San Diego State Pitcher Stephen Strasburg left early in the Aztecs 2nd game of the Mountain West Conference Tournament on Wednesday, after pitching 7 and 2/3 of an inning with 6 K's.  It seemed at first that he had strained his oblique muscle, but after confirming with Stephen and the teams trainer, both said parties said he had felt some tightness in his lower back, and was taken out by Tony Gwynn for precautionary reasons. Aztecs radio announcer Craig Elsten caught up with Strasburg following the game and asked him how he felt. www.619sports.net/aztecs
