The long awaited 2010 Phillies debut of Scott Mathieson is here as he was called up today when lefty Antonio Bastardo was placed on the DL with left elbow  “ulnar neuritis”.  Mathieson has been lights out in his position as the Lehigh Valley closer except for his most recent outing during which he gave up a game winning grand slam to Fernando Martinez. In his 25 outings, Mathieson  was 2-2 with a 2.43 ERA and 12 saves (5th in the IL). Opponents are hitting just .194 against him. Mathieson, coming off two Tommy John surgeries, throws very hard, with his fastball hitting 100 mph on the Lehigh Valley radar gun at times. In addition to the fastball, Mathieson has been throwing both his curveball and change in key situations.
