Pedro Strop thinks his problems aren’t physical. They’re mental.

The Orioles put Strop on the 15-day disabled list on Saturday with a lower back strain. He’ll use the time to work on his pitching issues.

Strop has an 0-2 record with a 6.11 ERA in 11 games with the Orioles.

“This is not the way that I wanted to fix whatever I was doing wrong,” Strop said. “Sometimes things happen for a reason. Of course I’m going to be working, and I’ll have time working on the stuff I have to be working on to be consistently successful on the mound. If you’re going to be helpful to the team you have to be consistent.”

Strop had a rough April, then for the first two weeks of May threw well, but his last five outings were rocky.

“I’m just going to have a clear mind and do what I know to do. My problem is more mentally than physically. I was trying to do much. I was rushing things. That’s what caused mechanical problems,” Strop said.

“I was lights out in the WBC,” Strop said. “I really don’t know if it effected me or helped me. It’s mental stuff. I wanted to do too much. I care a lot for the team.”
