It's a process of getting through that initial soreness, building up strength and building up endurance."Jennings said he thinks he is a "a week, maybe two at the most" behind from where he would normally be in previous springs.Jennings threw 63 pitches, nearly half in the first inning after an error by Edgardo Alfonzo led to an unearned run.The 29-year-old righty went 2-9 with a 6.45 ERA in Houston last year, His season ended in late August, when he had elbow surgery to repair a torn tendon.
