The D-Backs owner blames himself for the “terrible” addition of Jordan Montgomery

After making an unexpected run to the World Series a year ago, the Arizona Diamondbacks looked to expand their roster in hopes of building a consistent contender.

Instead, the D-Backs miss the playoffs after some of the team's better-known names failed to make the expected impact.

Team owner Ken Kendrick knows exactly who is responsible for at least one of these steps: himself.

“If anyone wants to blame anyone for Jordan Montgomery being a Diamondback, you're talking to the guy you should be blaming,” Kendrick told Arizona Sports. “Because I brought it with me [the front office’s] Attention. I pushed for it. They agreed to it – it wasn't in our plan. They know when he was signed – right at the end of spring training. And looking back, it was a terrible decision to invest that money in a man who performed as poorly as he did. From a talent perspective, it's our biggest mistake this season. And I am the perpetrator.

Montgomery joined the Diamondbacks on a one-year deal worth $25 million that includes an option for next season, but struggled this year, going 8-7 with a 6.23 ERA and spending time in the bullpen.

He was coming off a year in which he went 10-11 with a 3.20 ERA with the St. Louis Cardinals and Texas Rangers and was a key part of the rotation as the Rangers won their first World Series title the franchise won.

Signed by Arizona in March, Montgomery was the last of the major free agents to sign in the offseason after a weaker-than-expected market forced some players, many of them clients of agent Scott Boras, to sign short-term contracts sign. Montgomery fired Boras shortly after he signed with the Diamondbacks.
