The Arizona Diamondbacks moved Jordan Montgomery to the bullpen as the veteran left-hander continues to struggle in his first season with the team.

Montgomery, one of baseball's top free agents this offseason, didn't sign with the Diamondbacks until late March, ultimately landing a one-year, $25 million deal that includes a vesting option for 2025.

His agent at the time, Scott Boras, negotiated several similar short-term deals for his top free agents late in the offseason.
