Jimmy Rollins hasn't been in the lineup for the Philadelphia Phillies the last three days and hasn't been given an explanation.

The 35-year-old, who has played all 14 of his Major League seasons with the Phillies, is waiting for an explanation from Ryne Sandberg.

"Obviously he's upset about something," Rollins said. "That doesn't mean it's over the course of spring training, it could have been one specific incident. But he's upset about it. That's something when he's ready, he'll let me know."

Rollins said Charlie Manuel would always talk to him when he wasn't in the lineup, but that isn't the case with Sandberg.
