26-year old switch hitting Cliff Pennington came into this season as the full time starting shortstop for the A’s. He has played in 47 games this season and he is 37 of 169 (.219 avg, .635 OPS) with 19 runs scored, 3 homers, 17 RBIs and 5 stolen bases. Pennington’s bat is causing the A’s to rethink about the P.T. at SS. That’s because 27-year old righty swinging Adam Rosales did such a good job filling in for Mark Ellis (who is back) while he was injured. Rosales has played in 44 games for the A’s this year and he is 41 of 146 (.281 avg, .748 OPS) with 17 runs scored, 4 homers and 19 RBIs. The A’s just can’t afford to carry Pennington as the starting SS if he’s not hitting so look for Rosales to steal P.T. from him and he could eventually bump him to the bench.
