Angels pitcher Brandon Sisk will have Tommy John surgery on his left elbow, ending his 2012 season.
Sisk was acquired from the Kansas City Royals for right-hander Ervin Santana in October. He made two Cactus League appearances, allowing one hit and one run in two innings, before being reassigned to minor league camp March 11.
The recovery period is typically no shorter than 12 months.
The Angels reassigned pitcher A.J. Schugel to their minor-league camp, optioned pitcher Brandon Sisk to Triple-A Salt Lake and optioned outfielder Travis Witherspoon to Double-A Arkansas.
The Angels cleared a spot on their 40-man roster by outrighting right-handed reliever Bobby Cassevah on Thursday. Cassevah has 72 hours to either accept his assignment to the minor-league side or become a free agent.
Cassevah appeared in one game this spring, allowing a single and walking two batters but escaping the jam Sunday against the Oakland A’s.
The assignment comes as Cassevah was hoping to move past a disappointing 2012 season. He hurt his shoulder in spring training and pitched in just four major-league games all year, walking six and surrendering four runs in five innings (7.20 ERA). At Triple-A Salt Lake, Cassevah went 4-1 with a 6.22 ERA in the hitter-friendly Pacific Coast League, recording 10 saves in 12 opportunities.
The Angels could use Cassevah’s roster spot to acquire a player via trade or free agency, though it’s too soon to say if the Angels want to go that route. It’s also good news for 40-man roster pitchers Nick Maronde, Brandon Sisk, David Carpenter, Steven Geltz and Michael Kohn, whose chances of starting the season in the majors temporarily improve.
