  • *= closer-by-committee

Vulture Save Options for Saturday, September 21

  • Ryan Pressly (HOU): Hader has pitched in back-to-back games. 
  • Tanner Scott (SD): In case the team gives Suarez the night off after suffering his sixth blown save. 
  • Jorge López (CHC): Received yesterday off and Hodge has worked in consecutive contests. 
  • Ryan Thompson (ARI): Martinez has appeared in three straight, Puk in the previous two. 

Vulture Save Stashes for Sunday, September 22

  • Tommy Kahnle (NYY): If Weaver pitches today, it will be consecutive outings. 
  • Evan Phillips (LAD): He will be off today and if Kopech pitches, it will be back-to-back appearances. 

Three Takeaways

Is a committee coming soon to San Diego?: For the third time in his past six appearances, Robert Suarez allowed the game-tying or go-ahead home run in the ninth inning. He’s also allowed the game-tying or go-ahead run in five of his past ten games since August 28, resulting in a win, two losses, and converting four of seven save chances. All three home runs have come against his four-seam fastball, which he has thrown 74.3 percent of his pitches in this timeframe. He’s allowed 24 batted ball events with the pitch, a 41.7 hard-hit percentage with a .283 expected batting average, and a .369 expected weighted on-base average. He’s only producing a whiff 10.2 percent of the time while allowing an 83 percent contact rate with the pitch:

This will be a difficult needle to thread, but a 4.5 K-BB percentage an a 1.68 WHIP in his last 10 contests could mean fewer save chances in the near future and potentially in the playoffs. 

Hierarchical change in the Desert?: Not only did Justin Martinez get used for a third straight game, he appeared in the seventh inning. He last recorded a save on September 3 against the Giants. Last night, A.J. Puk secured his second save as a Diamondback, and first since August 4. However, he’s been the team’s best reliever since his acquisition. Through 26 games, he’s produced 39 strikeouts against four walks (two intentional) for a robust 39.8 K-BB percentage with a minuscule 0.63 WHIP and 1.32 SIERA over 24 innings. He’s thrown strikes 71.4 percent of his pitches with Arizona with a 21.1 swinging strike percentage and a 61.2 percent contact rate allowed. Fantasy managers will monitor usage patterns closely, but our hierarchy has shifted to a closer-by-committee with these two relievers. Your move Torey Lovullo. Of course, this will have to wait until Sunday based on recent usage patterns, Puk and Martinez should be unavailable in today’s contest. 

Bigge, Bigge, Bigge, can’t you see: An unexpected turn of events resulted in the first career save for Hunter Bigge. He worked a clean top of the ninth against the Blue Jays, preserving a combined shutout. It’s tough trusting any Rays reliever for saves not named Pete Fairbanks, and this remains true through the end of the season. However, those in keeper leagues should monitor how Bigge gets deployed in his team’s remaining eight games. A strong finish could yield a higher leverage role in 2025 and potentially a shot at closing games by the second half of next year.

He threw 20 pitches (55 Strike%) and induced four whiffs (16 SwStr%) while working around a hit and a walk. Although he bounced back from a blown save in his last appearance, his walk rate (12.3 percent) must improve next season.

Emmanuel Clase retired the side on 14 pitches (11 strikes – 78.6 Strike%) and induced one whiff. He’s been scoreless across all eight appearances this month. He has worked on consecutive days and in four of the last five. He should be provided more rest with his team clinching a playoff spot.

He threw 19 pitches (15 strikes – 78.9 Strike%) and generated five whiffs (26.3 SwStr%).

  • Hierarchy remains: Kyle Finnegan | Derek Law | Jose A. Ferrer

Vulture Save Options for Friday, September 20

  • Ryan Thompson (ARI): Although Puk has pitched better, Thompson would face the right-handed heart of the Brewers lineup if a save chance is provided. Martinez has appeared in back-to-back games. 
  • Cade Smith (CLE): Clase and Gaddis have pitched in two straight games. 
  • Collin Snider (SEA): Muñoz and Taylor have appeared in the two previous games. 
  • Tyler Rogers (SF): Walker logged consecutive outings in Baltimore. 

Vulture Save Stashes for Saturday, September 21

  • José Buttó (NYM): If Díaz pitches tonight, it will be consecutive appearances. 
  • Tyson Miller (CHC): If Hodge and López pitch Friday, it would be back-to-back games. 

Three Takeaways

Kenley’s shoulder: Although he gutted out his 27th save on Wednesday while facing Tampa Bay, Kenley Jansen reported he worked through a sore shoulder. He was not placed on the injured list before last night’s contest, but fantasy managers should monitor his status for the last week of the season. If Boston gets eliminated from playoff contention, he may be shut down for the remainder of the season. Stashing Chris Martin, just in case, makes sense.

Edwin’s four-seam: After suffering a blown save on August 28, Edwin Díaz has changed his approach, using his four-seam fastball 72.2 percent of his pitches over his last 11 appearances. It’s resulted in 19 strikeouts against one walk while only allowing one earned run. For example, here’s his Stastcast box from last night’s outing while striking out the side against Philadelphia: 

Next, his splits from August 29 through last night: 

  • Four-seam fastball: 72.2 percent usage, 13:1 K:BB (46.2 K-BB%), 17.3 swinging strike percentage, .203 expected weighted on-base average (xwOBA)
  • Slider: 27.8 percent usage, 6:0 K:BB (54.5 K-BB%), 37.5 swinging strike percentage, .050 xwOBA

This tweak may provide a strong bounce-back campaign in 2025. Stay tuned. 

Chapman’s second half: There’s always risk in believing in short sample sizes. Since the All-Star break, Aroldis Chapman has the eighth-best K-BB percentage (30.2) and has converted six of eight save chances. He’s attributed his strong season to being in better shape entering the season, but he’s also adjusted his pitch mix: 

Comparing his full season results with the second half, he’s improved his strike percentage by 7.3 percent, his swinging strike percentage by 2.1 percent, and his first-strike rate by just under ten percent. He’s never been known for his control, but throwing more sinkers has benefited his results. As a pending free agent, could he reemerge as a trusted closer in 2025? Time will tell, but things went well for Kirby Yates in his Age-37 season this year.

Three Takeaways

Detroit’s bullpen surging in September: Using Fangraphs Win Probability Added metric, the Tigers bullpen ranks first in September, fueling a potential postseason berth. Entering game play on Thursday, Detroit’s a half-game behind Minnesota for the last Wild Card spot. These three relievers are shining, and they may be a key component over the team’s remaining nine contests: 

  • Jason Foley: 10 appearances, two losses, six saves, 9.1 IP, 8:2 K:BB, 0.75 WHIP
  • Tyler Holton: eight appearances, two wins, two saves, two holds, 11.2 IP, 10:1 K:BB, 0.52 WHIP
  • Will Vest: seven appearances, one save, four holds, 8.1 IP, 7:1 K:BB, 0.60 WHIP

Usage patterns limit Dream Weaver: Currently ranking third in Win Probability Added in September, Luke Weaver has recorded two wins, two saves, and a hold in his last five appearances with 16 strikeouts against three walks (48.2 K-BB%) across 7.1 innings and a 0.68 WHIP. However, he’s recorded five or more outs in his last three games, retiring 16 of 18 batters. With a postseason spot clinched, the team may start streamlining his workload. Still, until the division gets clinched, he may be deployed in multiple-inning outings. This will keep relievers like Tommy Kahnle and Ian Hamilton on the periphery of fantasy relevance over the last week and a half of the season. 

Appreciating Yates: Only Emmanuel Clase has produced a higher Win Probability Added this year than Kirby Yates. Securing his 31st save last night, Yates has logged 58.1 innings while converting 31 of 32 save opportunities with 83 strikeouts against 27 walks (24.7 K-BB%) in his Age-37 season. His 0.852 WHIP has benefited those fortunate to add him earlier this season. As an unrestricted free agent, he can dictate his role, though a return to Texas seems inevitable. It’s tough assessing aging relievers, but the time he missed because of his injury may yield another strong campaign in 2025.

Monkey Bytes: September 18

Tuesday provided six reliever wins, though one accompanied a blown save (Josh Hader) and seven saves. Marcus Stroman recorded his first save of the season, logging three innings during a lopsided win in Seattle, but it’s the second of his career. Our condensed game recaps cover yesterday’s high-leverage events of interest.

Closer CliffsNotes

Alexis Díaz (CIN) worked around Orlando Arcia’s two-out single with a game-ending strikeout, preserving a one-run win over Atlanta and securing his 28th save. He threw 19 pitches (12 strikes – 63.2 Strike%) and produced four whiffs (21.1 Strike%) while striking out two in his outing. He’s been scoreless in seven appearances this month with a win and converting four saves, with seven strikeouts against zero walks. Emilio Pagán recorded his seventh hold, giving up a hit and striking out one in a scoreless eighth. Brent Suter was awarded his first win, stranding a runner and yielding a hit in one-third of the seventh. 

  • Hierarchy remains: Alexis Díaz | Emilio Pagán | Fernando Cruz

Jason Foley (DET) retired the side and stranded the “place” runner at the bottom of the tenth, preserving a two-run win in Kansas City and locking down his 25th save.

Héctor Neris (HOU) allowed a walk and recorded a strikeout in a scoreless bottom of the tenth, preserving a one-run win while securing his 18th save, his first with the Astros this season. He threw 18 pitches (55.6 Strike%) and induced three whiffs (16.7 SwStr%). Josh Hader logged a multiple-inning outing against his former team to a smattering of boos but uncorked a wild pitch at the bottom of the eighth, scoring Fernando Tatis Jr. with the game-tying run, resulting in his third blown save. After tossing a clean ninth, Hader collected his eighth win. He retired all four batters, two via strikeout on 12 pitches (83.3 Strike%) with three whiffs (25 SwStr%).

  • Hierarchy remains: Josh Hader | Ryan Pressly | Bryan Abreu

Lucas Erceg (KC) suffered his sixth loss.

He threw 35 pitches (21 strikes – 60 Strike%) and induced four whiffs. This snapped a five-game scoreless streak, representing his first loss since August 29.

  • Hierarchy remains: Lucas Erceg | John Schreiber | Kris Bubic

Jesús Tinoco (MIA) allowed three hits and two earned runs while striking out one at the top of the ninth against his previous employer in a non-save appearance.

He recorded a strikeout, allowed a single, and induced a game-ending Bo Naylor groundout, preserving the three-run win during his ninth save. He threw eight pitches (75 Strike%) and generated four whiffs. This marked his first save since August 5. Jhoan Durán worked a scoreless eighth, then returned for the ninth. After allowing José Ramírez’s double and striking out Josh Naylor, he was removed after walking Lane Thomas. Durán notched his seventh hold and recorded two strikeouts while throwing 30 pitches (66.7 Strike%) with four whiffs.

  • Hierarchy remains: Jhoan Durán | Griffin Jax | Cole Sands

Marcus Stroman (NYY) recorded his first save and first since 2014, tossing the last three innings in Seattle.

He threw 21 pitches (66.7 Strike%) and generated five whiffs (23.8 SwStr%). He’s converted three straight saves but lost his modest three-game scoreless streak in this outing. 

  • Hierarchy remains: Mason Miller | Tyler Ferguson | Michel Otañez

Jeremiah Estrada (SD) retired both batters, keeping his team within one run. Adrian Morejon suffered his second loss, allowing two hits and the “place” runner to score on Kyle Tucker’s RBI single during one-third of the tenth.

José Leclerc retired the side for his 12th hold in the seventh. David Robertson gave up two hits and an earned run in the eighth while getting credit for his 32nd hold. Kirby Yates navigated around two walks for a scoreless ninth, finishing the five-run victory. 

  • Hierarchy remains: Kirby Yates | David Robertson | José Leclerc

Vulture Save Options for Wednesday, September 18

  • Tanner Scott (SD): Suarez and Adam have appeared in three consecutive games. 
  • Will Vest (DET): Hinch has pulled all the right strings, but Foley has pitched in three straight contests; Holton has worked in two of the last three, throwing 54 pitches. 
  • Kris Bubic (KC): If going against the grain, Erceg logged 35 pitches last night, and Bubic could match up against the heavy left-handed top of the Tigers lineup. 
  • Cole Sands (MIN): Durán threw 30 pitches in yesterday’s win, and Jax appeared in back-to-back games. 

Vulture Save Stashes for Thursday, September 19

  • Andrew Kittredge (STL): If Helsley pitches today, it marks consecutive outings. 
  • Tony Santillan (CIN): If Díaz appears today, he will be off on Thursday. 

Today’s Takeaways

Kimbrel and the Cliff: Any high-leverage reliever has a shelf life. Craig Kimbrel has transitioned from an All-Star snub, per many analysts, in the first half to a questionable postseason spot on the roster. After last night’s implosion, he has made 18 appearances in the second half without a save. Across 17 innings, he’s produced 20 strikeouts against 15 walks with a 2.177 WHIP, one win in four decisions, and one blown save. Watching the twilight of one of the best relievers is tough, but working with declining velocity, his days as a closer may be finished. 

Miller’s “second half”: While assessing Mason Miller and projecting him for 2025, marrying his strong start of the season with less pronounced strikeout rates throughout his rookie campaign must be accounted for and last night marked his 50th game, putting June 18 as the midpoint of his season. Over his last 25 games, he’s suffered a loss while converting all 14 save chances across 28 innings. He’s generated 39 strikeouts versus seven walks (29.4 K-BB%) with a 0.86 WHIP, 66.4 strike percentage, 19.1 percent swinging strike rate, and a 64.2 contact percentage allowed. It’s all impressive, but not quite at the levels he produced in his first 25 games. There’s nothing wrong with a reliever on pace for 90 strikeouts in this sample, and he will be projected as a top-five reliever next season. Note his 10-game rolling chart and target accordingly:

Monkey Bytes: September 17

Monday’s 10-game slate yielded wins by five relievers and four saves. Colin Rea (MIL) recorded the first save of his career while providing his teammates rest during a win over the Phillies. There were also four one-run contests with playoff implications. Our condensed recaps cover all of the high-leverage events of interest.

Closer CliffsNotes

Ryan Thompson (ARI) suffered his fifth loss during two-thirds combined innings in Colorado. He allowed Brenton Doyle’s lead-off single, followed by a stolen base, resulting in an intentional walk of Ryan McMahon. Thompson induced a ground ball, but a throwing error on the attempted double play scored the game-winning run, resulting in an unearned run on his ledger.

Ferrer retired the side and recorded a strikeout in the ninth, facing the Mets’ 4-5-6 lineup pocket.

  • Hierarchy remains: Kyle Finnegan | Derek Law | Jose A. Ferrer

Vulture Save Options for Tuesday, September 17

  • Hunter Gaddis (CLE): Clase has pitched the previous two games, but he has proven capable of working three in a row, especially against a divisional rival. If Clase pitches tonight, Gaddis carries over to tomorrow. 
  • Tyler Holton (DET): Foley has appeared in consecutive contests. 
  • Phil Maton (NYM): Díaz has pitched in back-to-back games. 
  • Jeremiah Estrada (SD): Suarez, Scott, and Adam have all logged consecutive outings. 

Vulture Save Options for Wednesday, September 18

  • Depends on usage patterns in Tuesday’s slate. 

Three Takeaways

Walters’ positive first impression: Andrew Walters could become a fixture in the Guardians’ deep bullpen after rising through the minor league ranks. He’s recorded three scoreless appearances since his promotion, including his first career win in last night’s come-from-behind win over the Royals. He’s only produced two strikeouts but has generated a 25-swinging strike percentage and may make the postseason roster with a strong finish this season. Those in keeper leagues should monitor his results closely. 

Wild Card, American League: After last night’s results, the Twins hold the last Wild Card spot with its lead over Detroit narrowing to one-and-a-half games, and Seattle moved within two games of the last postseason spot. Here are the updated playoff odds courtesy of Fangraphs: 

Wild Card, National League: Arizona’s loss and the Mets’ win in the late innings put three teams within a game of the two playoff spots. Entering game play tonight, Arizona sits in the second Wild Card spot, one game ahead of the Mets, who have a one-game cushion over Atlanta. However, this is hardly decided. Managing workloads and preserving late leads will be pivotal down the stretch.
