The Astros released Brett Wallace on Wednesday morning, ending his hopes of making the club’s opening day roster as a non-roster invitee.

“He’s been a big part of this organization for the past few years,” Astros general manager Jeff Luhnow said of Wallace. “But we didn’t see a role for him at the big league level and we’re having trouble figuring out where he fit in and wanted to give him a chance to catch on somewhere else.

“It was a tough decision because he’s been a great part of this organization for the past four years, but we feel it’s in our best interest and his best interest that he catches on somewhere else.”

Wallace, who made the Astros’ 2013 opening day roster, hit .221 last year over 79 games. He was taken off the 40-man roster in February.
