Yankees shortstop Derek Jeter has a sore right hamstring, but expects to resume running on Monday. Jeter skipped the team's running drills on Sunday. "It's no big deal," Jeter said. "It's really not an issue." He also said that the soreness won't affect his training for next month's World Baseball Classic. "It's not a pull. It's not a strain," manager Joe Girardi said. "It's a little sore. Obviously we're going to watch him and make sure he's ready."
