Intrigued by Mosebach's raw arm strength, the Phillies selected him in the 2008 major league Rule 5 draft, but they couldn't find a place for him and returned him to the Angels last spring. As a full-time reliever for the first time, he reached the majors in July and made a positive impression despite pitching in just three games. He further bolstered his standing with a solid showing in the Dominican League. Mosebach is a hard-throwing sinkerballer in the vein of Rafael Rodriguez. While he throws harder than Rodriguez, Mosebach's breaking ball isn't nearly as advanced. His fastball averaged nearly 94 mph in the big leagues, and he peaks at 96 while rarely dipping below 92. His heater features hard, late sink, and he has improved his command to his arm side, which will be crucial to neutralizing lefthanders. His groundball-inducing, mid-80s slider features sharp tilt when he stays on top of it, but that's often a 50-50 proposition. Like any sinkerballer, he gets hit when he leaves the ball up. Mosebach limited minor leaguers to a .197 average while allowing only one home run in 67 innings last season, though he tends to walk too many lefthanders. Mosebach is 25 and has two minor league options remaining, just like Rodriguez, whom he'll battle for a bullpen job in spring training.
Mosebach turned down an offer from the Nationals as a draft-and-follow after they took him in 12th round in 2004, then signed with the Angels for $152,000 after going in the ninth round in 2005. Had he not turned pro, he would have attended Tennessee. Because he had a heavy workload at Hillsborough (Fla.) Community College, the Angels kept him on strict pitch counts in his pro debut and had him skip instructional league. His velocity varied from 87-95 mph with some life. Mosebach's slider was up to 87 as an amateur but sat near 82 after he signed. His slider is an average offering with depth and good tilt at times, though his front side tends to fly open, causing his stuff to flatten out and his control to suffer. When he stays on line to the plate, his command improves and he has a tendency to break lots of bats. The Angels place a priority on teaching their young pitchers a changeup, and Mosebach added one to his arsenal last summer. He profiles as a back-of-the-rotation starter and eventually could find a home in the bullpen. He's in line for an assignment to low Class A Cedar Rapids in 2006.

Mosebach turned down the Nationals as a draft-and-follow and the University of Tennessee before signing with the Angels for $152,000. He was kept on tight pitch counts in his pro debut, but he flashed noteworthy stuff. His fastball varied from 88-95 mph with late life, while his low-80s slider had good depth and tilt at times. Mosebach is just beginning to craft a changeup. He tends to fly open on the front side of his delivery, causing his stuff to flatten out and command to suffer. "He looks like he is throwing easy, but his ball has good carry through the glove and can shatter some bats," Kotchman said. "He's 6-4 with a young Derek Lowe body. His arm is loose and works as good as anybody's."
