Rangers Acquire Andrew Chafin

The Rangers announced they’ve acquired lefty reliever Andrew Chafin from the Tigers. Pitching prospects Joseph Montalvo and Chase Lee are going to Detroit. Texas designated righty Jonathan Hernandez for assignment in a corresponding move.

The 34-year-old Chafin is in the midst of yet another solid season. He’s pitched 37 innings of 3.16 ERA ball with a big 30.9% strikeout rate, a 9.9% walk rate and a 35.8% grounder rate. He’s been particularly dominant of late, rattling off 17 innings of one-run ball with a 26-to-5 K/BB ratio dating back to early June.

That 35.8% grounder rate is an uncharacteristically low mark for Chafin, who’s changed up his pitch usage this year. He’s throwing more sliders than ever before (46.4%) and missing more bats as a result but also yielding more balls in the air and a few more walks than in recent years. Chafin’s velocity is down a bit from its 93-94 mph peak, however, sitting around 92 mph on average this year with both his four-seamer and sinker. It’s possible the change in repertoire was borne out of the diminishing life on those harder offerings. Regardless, it’s been an effective recipe for the well-traveled southpaw, who’ll now suit up for the sixth team of his 11-year career.

Chafin is playing on a one-year, $4.75MM contract, although the Rangers are picking up another year of possible control over him in the form of a 2025 club option valued at $6.5MM (a net $6MM decision after factoring in a $500K buyout). He’s owed about $1.42MM of his $4.25MM base salary but has a handful of incentives approaching that could boost the value of that contract. Chafin would earn a $125K bonus for pitching in his 50th game — he’s at 41 appearances — before taking home $250K bonuses for reaching 55 and 60 games, a $300K bonus for 65 games and a $325K bonus for reaching 70 appearances. The last of those milestones could be hard to reach, but the Rangers will be on the hook for some additional incentives of note, which will all come with a 30% tax given their luxury-tax status.

With Chafin’s acquisition and Cody Bradford’s return from a 60-day IL stint, a Rangers bullpen that has lacked an established left-handed option for much of the season will suddenly have two quality options in that regard. Chafin will join a late-inning mix including Kirby Yates, David Robertson and Jose Leclerc. He’s held lefties to an awful .180/.261/.213 batting line this season, and while righties are enjoying more success at .293/.366/.390, they’re not managing much power against the southpaw. In his career, Chafin has yielded only a .234/.313/.361 line to right-handed opponents, though much of that came with a more vibrant fastball and different mix of his three pitches.

The trade for Chafin underscores the fact that yesterday’s trade of Michael Lorenzen to the Royals was less about selling off in the midst of a disappointing season and rather opening space for the return of several other veteran starters (e.g. Max Scherzer, Tyler Mahle, Dane Dunning and, further down the road, Jacob deGrom). Much of the cost-savings from that trade of Lorenzen — earning $4.5MM with incentives of his own — will now be reallocated to the comparably priced Chafin.

Montalvo is the more highly regarded of the prospects headed to Detroit. Baseball America ranked him 19th on their most recent update of the Texas system, crediting him with a plus changeup and the ability to spin his low-90s fastball. He’s dominating lower minors opponents, striking out nearly 30% of batters faced with a 2.44 ERA in High-A. Lee is an upper minors reliever who’ll be eligible for the Rule 5 draft next offseason if he’s not added to the 40-man roster. He lost the first couple months of this season to injury but had a 3.98 ERA in Triple-A last year.

ESPN’s Jeff Passan first reported the Rangers were finalizing a deal for Chafin. The Athletic’s Ken Rosenthal confirmed an agreement was in place. Evan Grant of the Dallas Morning News reported the Tigers would receive Montalvo and Lee.
