August 22: Houston finalized their one-year deal with Kimbrel this afternoon. They also activated Lance McCullers Jr. from the 15-day injured list to start tonight’s game in Baltimore. They cleared active roster space by optioning rookie Logan VanWey to Triple-A and placing southpaw Bennett Sousa on the 15-day injured list. Brandon Walter, who has been out for a month with elbow inflammation, was moved to the 60-day IL in the necessary 40-man move.
Sousa is dealing with elbow inflammation himself. Manager Joe Espada said Sousa reported discomfort after Tuesday’s appearance and has not progressed as hoped. He’s flying back to Houston for further evaluation while the team continues its road trip (link via Chandler Rome of The Athletic).
August 21: The Astros are in agreement with Craig Kimbrel on a major league contract, reports Jeff Passan of ESPN. The SportsMeter client was just granted his release from a minor league deal with Texas, per Evan Grant of The Dallas Morning News. Houston will need to create space on both the active and 40-man rosters.
Kimbrel spent a little more than two months in Triple-A with Texas. He signed in June one day after electing free agency from the Braves. That followed a bizarre sequence in which Kimbrel’s initial team called him up for one day. The nine-time All-Star labored through a scoreless inning in his lone appearance. That remains his only MLB outing this season. Kimbrel has otherwise divided the year between the upper minors affiliates of Atlanta and Texas.
Between the two organizations, Kimbrel carries a flat 3.00 earned run average in 39 minor league innings. He has recorded an excellent 31.5% strikeout percentage but has walked nearly 13% of batters faced. It’s a similar profile as Kimbrel has shown in the big leagues in recent seasons. He had a strikeout rate in the 31-34% range while issuing free passes between 10-13% of the time in both 2023 and ’24. Kimbrel remained effective with the Orioles in the first half of the ’24 season, but he melted down after the All-Star Break (20 earned runs in 17 innings) and has barely gotten an MLB look since then.
While the Triple-A results are solid, Kimbrel’s raw stuff hasn’t been as sharp this year. His fastball has been in the 92-93 MPH range in Triple-A; he averaged less than 92 on the heater in his only big league outing. He’d sat closer to 94 last year and was up to 96 as recently as 2023. He missed enough bats against minor league hitters to intrigue the Astros, whose bullpen has struggled of late.
Only the Rockies, Blue Jays and Nationals have a higher bullpen ERA than Houston does over the past month. The Astros lost Josh Hader for at least the remainder of the regular season to a capsule strain in his shoulder. Bryan Abreu is an elite back-end arm in his own right, and they have a strong left-handed trio of Steven Okert, Bryan King and Bennett Sousa. Abreu is essentially their only reliable righty reliever. Kimbrel’s command makes him a volatile bullpen piece as well, but he has more swing-and-miss upside than Enyel De Los Santos or Shawn Dubin provide in the middle innings.
The signing is expected to become official on Friday. Getting the deal done before September 1 means Kimbrel will be eligible for postseason play if the Astros qualify. He’ll have a little over five weeks of regular season action to convince the front office and coaching staff he’s worth carrying in October. Houston leads the Mariners by 1.5 games in the AL West. They’re 3.5 games clear of the Royals, the top team that is not currently in playoff position.
