Vicente Padilla was pulled after 2.2 innings in which he dominated for the first two on mostly an 88-91 mph fastball (CC starter Felipe Paulino was 94-96, his usual reported FB speed, so it wasn't the guns), then struggled through several batters in the third, throwing about 50% junk balls (58-62 mph "curveball"/eephus). He was visited by the Frisco trainer before being pulled and left the dugout area soon thereafter.
Haven't heard anything else since I've left the game, but there was definitely something weird in that third inning.
