Has been strictly a RP the last few years. Raw numbers look good at LHV, but BABIP of .130 says they're a bit fluky. Extreme GB pitcher this season, probably another fluke unless Phillies coaches made changes (like sharpen his changeup).
Think this means the 5th starter is going to be a bullpen game.
Uelmen, Erich 6’3 195 (4-17 CHI) 
Uses an abbreviated windup, has toned down hand movement since college. Throws across body with low 3/4 arm slot and will vary timing. Gets himself in strong fielding position after delivery. Repeats mechanics very well. Sinker, his primary pitch. Gets weak contact more than swing and misses, bottom falls out of the pitch making it difficult to square up. Works everything low in the zone. Above-average pitch. Leans heavily on it. 92-94, t96. Grade: 55 His 83 MPH slider is his best secondary pitch. Good movement but doesn't miss bats, instead getting more groundballs. Will throw the pitch in any count and it plays well off of the sinker. Grade: 50 Changeup is so-so. Control over command profile. Throws strikes but will leak over the middle of the plate too much. When he's in sync he lives on the lower quadrants and even below the zone. Thin margin for error and below average command is living on the fringes of a big league roster. Control: 50 | Command: 40 Future relief arm. Could get some extra ticks on the fastball with a permanent shift to the pen. Ability to work multiple innings increases big league utility with expanded staffs.
