Pinch-hitter Mike Carp singled in Daniel Nava in the bottom of the 10th to give the Red Sox a second straight walkoff win over the White Sox on Thursday. Carp's single off Ronald Belisario was his first hit since he came off the disabled list Monday. He had been hitless in 17 at-bats since May 22. The Red Sox will continue to employ him primarily as a pinch-hitter unless someone wants to trade for him and give him an expanded role.
