SAN FRANCISCO -- Two highly regarded Padres pitching prospects appear to be on their way to making significant inroads in their recoveries from injuries. Right-hander Casey Kelly, who is regarded as the Padres' top prospect by MLB.com, allowed four earned runs on six hits in two innings for the Padres' entry in the Arizona League on Monday. He struck out three and didn't issue a walk. Kelly has been on the disabled list since April with a strained right elbow ligament. His outing Monday was the first time that he's pitched in a game since April, when he was pitching with Triple-A Tucson.
Kelly -- who had a 2.25 ERA in two starts with Tucson before the injury -- will pitch again on Saturday in Arizona. Erlin, a left-handed pitcher who is regarded as the Padres' sixth-best prospect, has been sidelined since May with tendinitis in his elbow. He threw live batting practice on Tuesday and will do so again Friday. Erlin was 2-1 with a 2.67 ERA in seven starts before going on the DL.
