Closer Monkey’s Leverage Ledger | August 30

Friday’s full slate tilted towards relievers who recorded seven wins against five losses while securing nine saves. Three relievers recorded their first save of the season. Two of the nine saves required more than three outs. Here they are in condensed form:

For the save streamers:

Vulture Save Options for August 30

  • Riley O’Brien (STL): If he’s available, he should be the preferred option in the ninth. JoJo Romero has pitched in back-to-back games. 

Under the Hood

Entering with a one-run lead, Andrés Muñoz allowed a lead-off double by Nolan Jones, followed by Brayan Rocchio’s game-tying RBI single, though the throw from home took a strange hop going wide of home plate, letting Rocchio reach third. Facing Steven Kwan, Muñoz induced a flyout, but it was a walk-off sacrifice fly, resulting in his second loss and a seventh blown save. He finished with two hits and two runs (one earned) during one-third of an inning. First, his illustrator:

And, his results:

He has allowed at least a run in four of his last five appearances, and multiple hits in three. As the first chart will show, he has been working with reduced velocity since June:

This coincides with a declining strikeout percentage while allowing more contact:

For the visual crowd, like myself, his splits by month and half in 2025:

This could be as simple as fatigue, but it’s tough to provide a closer with extra rest while trying to qualify for a postseason berth. Keep tabs on his velocity, WHIP, and results through September.

Here are the remaining leverage events of interest from Friday.

Leverage Ledger

Arizona DiamondbacksCapping a combined shutout against the Dodgers, Jake Woodford recorded his second save, entering against the Dodgers’ 3-4-5 lineup pocket and allowing a two-out walk to Teoscar Hernández ahead of a game-ending strikeout of Dalton Rushing. He threw 19 pitches (57.9% strike rate) and induced one whiff.

This marked his first usage in the ninth inning as the point of entry and only his second appearance this month, not as a multi-inning reliever.

  • Kyle Backhus secured his ninth hold, retiring the side versus the 9-1-2 hitters in the eighth.
  • Jalen Beeks gave up a hit and recorded a strikeout in a scoreless seventh for his 13th hold.

Kyle Finnegan did the heavy lifting in this contest. He took over at the bottom of the seventh and stranded a runner, then returned for the eighth, retiring the side. He was awarded his fourth win, logging 1.2 scoreless frames while issuing a walk and striking out three on 22 pitches (59.1% strike rate) with five whiffs (22.7 SwStr%).
