The Athletics have selected the contract of right-hander Brian Schlitter from Triple-A Las Vegas, the team announced. He’ll take the 25-man spot of closer Blake Treinen, whom the A’s placed on the injured list Saturday, and give the club a full 40-man roster.

This will be Schlitter’s first time in the majors since 2015, when he threw 7 1/3 innings with the Cubs. Schlitter saw action with the Cubs in two other seasons (2010 and ’14), and combined for a 5.40 ERA/4.26 FIP with 5.27 K/9, 3.27 BB/9 and an excellent 56.5 percent groundball rate in 71 2/3 frames with the club. He hasn’t pitched in the majors for anyone else.
