But with the club designating David Pauley for assignment, Cassevah may get time to prove he's back to being the reliable sinkerballer of last year.
"As long as you get outs and throw strikes," Cassevah said. "I think I'm up here for good, but you never know. I can get up here and start walking guys and I'm down in Triple-A tomorrow."
Cassevah began the year on the disabled list with right shoulder inflammation and was inconsistent in the Minors, compiling a 5.29 ERA, a 1.71 WHIP and a 1.83 strikeout-to-walk ratio in 17 innings at Class A and Triple-A.
The 26-year-old didn't feel like his release point was right early on, which didn't give him much feel for his sinker and led to walks. But he was encouraged by his last three one-inning appearances for Triple-A Salt Lake, when he didn't walk anyone, gave up just one hit and struck out four.
"I had some kinks I needed to work out," Cassevah said. "Everything wasn't really consistent with my fastball and off-speed stuff. I had to get more work in, and everything's good to go now."
"Last year, he had a terrific season for us," Scioscia added. "There's nothing that says that kind of arm won't move to the back of the bullpen as depth and be able to pitch, whether it's the seventh, eighth or ninth inning, whatever. We'll just see how it evolves."
