After making an unexpected run to the World Series a year ago, the
Montgomery joined the Diamondbacks on a one-year deal worth $25 million that features an option for next season, but struggled this year, going 8-7 with a 6.23 ERA and spent time in the bullpen.
He was coming off a year in which he went 10-11 with a 3.20 ERA splitting time with the St. Louis Cardinals and Texas Rangers and was a key part of the rotation as the Rangers went on to win the franchise’s first World Series title.
Signed by Arizona in March, Montgomery was the last of the major free agents to sign in the offseason after a softer-than-expected market developed and forced some players, many of them clients of agent Scott Boras, to sign short-term deals. Montgomery fired Boras soon after signing with the Diamondbacks.
