Cassevah has yet to appear in a Cactus League game because of inflammation in his right shoulder, which flared up once again during a bullpen session earlier this week and forced him to temporarily shut it down.
The 26-year-old sinkerballer hopes to be cleared to pitch off a mound again on Monday, and then get in game action later in the week. He's thinking that timetable could be enough to have him ready for the season.
"I think so," Cassevah said. "As long as I get in a [simulated] game Wednesday or Thursday, and then face some live hitters a couple of times, that's about it. That's all you need."
Cassevah missed 17 games with shoulder inflammation last April, but was a crucial member of the Angels' bullpen upon being called up from Triple-A in mid-June -- posting a 2.72 ERA and a 1.19 WHIP in 30 games down the stretch.
"Hopefully I can be ready [to start the season]," Cassevah said. "I see the doctor tomorrow and hope to start throwing again tomorrow."
