Polanco leads the Pirates with a career-high 23 home runs, 81 RBIs and 61 extra-base hits. He batted .254 this season.

Polanco dislocated his throwing shoulder on an awkward slide into second base on a double last Friday against Miami. He had surgery Wednesday, and the Pirates said it is projected to take seven to nine months for a return to action.

Along with injuring his shoulder, Polanco bruised his knee on the slide. He has played all five of his major league season with Pittsburgh.
