Bobby Cassevah pitched 50 games with the Los Angeles Angels over three seasons.
He was drafted in the 34th round in 2004 by the Anaheim Angels, signed by scout Tom Kotchman and began his career in 2005 with the AZL Angels, going 2-5 with a 5.40 ERA in 15 games (4 starts), allowing a .318 average. He pitched for the Orem Owlz in 2006, going 2-5 with a 6.80 ERA in 16 games (10 starts). Despite a .337 opponent average and almost a walk per inning (38 in 41), the Angels stuck with him. He became a reliever in 2007 and did well, going 2-1 with a 2.75 ERA in 24 relief appearances between the Orem Owlz and Cedar Rapids Kernels. In 2008, he went 2-3 with a 3.79 ERA in 44 relief outings for the Rancho Cucamonga Quakes. He went 3-7 with a 3.68 ERA in 57 games for the Arkansas Travelers in 2009.
On December 10, 2009, the Oakland Athletics drafted him from the Angels in the 2009 Rule V Draft. He was offered back at the end of spring training as he failed to make the A's roster on the strength of two innings of work, then was called up to the major league club a few days into the season, after one appearance for the Salt Lake Buzz, when Robb Quinlan was sent down. He made his debut on April 9, giving up only one hit in 2⅓ innings against, who else, the A's. He saw his most extensive action in 2011, with a 1-1, 2.72 record in 30 games (39 2/3 innings). He struggled in four 2012 outings and began the jaunt into baseball oblivion, last pitching in the Colorado Rockies system in 2013.
