Monkey Bytes: September 7

One game was postponed on Friday, leaving the slate one short of being full. Washington and Pittsburgh will play a split doubleheader later today. Three relievers recorded wins, including one in extra innings on Oakland’s walk-off in the 13th against Detroit. Six saves were secured, though one was a surprise in Boston, segue alert.

Roster Notes and Injury Updates

Boston Red Sox With Kenley Jansen being unavailable with lat soreness, it’s unfortunate timing for Liam Hendriks. He suffered a slight setback when he could not appear on consecutive days during his rehab assignment. He still believes he will pitch this season, but the window’s getting shorter.

Colorado RockiesVictor Vodnik fired a clean inning in his first rehab outing for Double-A Hartford last night. He recorded two strikeouts while throwing 13 pitches (9 strikes – 69.2 Strike%).

Minnesota Twins The team announced that Louie Varland will enter the bullpen for the stretch run. He’s made nine appearances as a reliever in his career, posting 22 strikeouts against two walks (26.3 K-BB%) with a 0.97 WHIP across 18.2 innings.

New York Yankees – Per Bryan Hoch, Ian Hamilton will be activated before Saturday’s game. He should be eased into high-leverage events but become a factor for save chances based on performance moving forward. 

Seattle MarinersGregory Santos hit 96 m.p.h. on the radar during his rehab outing last night. He allowed a soft-contact single and recorded a strikeout on 15 pitches (60 Strike%).

Next, our condensed recaps cover Friday’s high-leverage events of interest.

Vulture Save Options for Saturday, September 7

  • Tanner Scott (SD): Although he’s shared the same workload as Robert Suarez, Scott’s pitch count and durability make him the pivot for the save chance in this match-up.
  • Pierce Johnson (ATL): Iglesias and Jiménez pitched three of the previous four days. If they pitch again today, you will still have Johnson for tomorrow’s vulture save opportunity. 
  • Yennier Cano (BAL): Dominguez threw 28 pitches during his four-out save. 
  • Emilio Pagán (CIN): Díaz and Santillan have appeared in back-to-back games. 

Vulture Save Stash for Sunday, September 8

  • Phil Maton (NYM): If Díaz pitches today, it will be consecutive appearances and three in the last four days.

Three Takeaways

DreamWeaver: This may not be the answer for the entirety of the postseason, but Luke Weaver recorded his first career save, sealing a combined shutout of the Cubs on the road. As this chart indicates, he did benefit from two called strikes:

When viewing his arsenal, one can see that his change-up represents the difference-maker during high-leverage events. It’s produced a 32.2 K-BB percentage, a 21.3 percent swinging strike rate, and a .223 weighted on-base average (wOBA). Although Aaron Boone was non-committal about the closer role going forward, he did say Weaver could see more save chances. Monitor the usage patterns closely this weekend and over the last three weeks. 

Jansen’s lat: His recent outcomes have not helped fantasy managers, but it’s worse not seeing the closer warming for the save chance with his team ahead by three runs. After last night’s game, Julian McWilliams of The Boston Globe reported that Kenley Jansen would not pitch until his lat issue subsided. This translates into a closer-by-committed approach moving forward. Here are the underlying statistics for three potential fill-in relievers over the last 30 days: 

  • Chris Martin: 23.9 K-BB%, 6.7 SwStr%, 87.8 percent contact rate allowed, 1.50 WHIP, 2.78 SIERA, 76.1 Strike%
  • Justin Slaten: 13.3 K-BB%, 15.2 SwStr%, 77.4 percent contact rate allowed, 0.82 WHIP, 3.37 SIERA, 76.1 Strike%
  • Josh Winckowski: 13.6 K-BB%, 9.9 SwStr%, 81.5 percent contact rate allowed, 1.50 WHIP, 3.27 SIERA, 69.5 Strike%

Cano’s “save”: Although Seranthony Domínguez gets credit for securing the save in last night’s win over the Rays, Yennier Cano’s appearance in the seventh represented the game’s most leveraged moment. He took over a bases-loaded situation with no outs at the top of the seventh, replacing Dean Kremer. Cano induced consecutive strikeouts of Jonny DeLuca and José Caballero before an inning-ending Ben Rortvedt pop-out for his 32nd hold, second most in the majors. He’s been scoreless in his last six outings with 11 strikeouts versus one walk while recording five holds.
