The Phillies have placed starting 3B Placido Polanco on the 15-day disabled list due to a sports hernia. Polanco has played in 89 games for the Phillies so far this year and he is 95 for 345 (.275 avg, .672 OPS) with 35 runs scored, 4 homers, 40 RBIs and 3 stolen bases. 33-year old Wilson Valdez and 28-year old switch-hitting Michael Martinez will likely share time at 3B until Polanco is ready to return to action. Valdez has played in 75 games for the Phillies so far this year and he is 47 for 199 (.236 avg, .578 OPS) with 25 runs scored, 0 homers, 17 RBIs and 2 stolen bases. Martinez has played in 65 games so far this year for the Phillies and he is 32 or 151 (.212 avg, .551 OPS) with 19 runs scored, 2 homers, 19 RBIs and 3 stolen bases.
