PHOENIX -- Cubs reliever Pedro Strop, who has been sidelined with a right hamstring strain since Thursday, is continuing to make progress and said Wednesday he expects to return to game action by the end of the regular season.
"Everything is pain-free. We're not trying to do too much," Strop said. "We're letting that thing heal. We're going to do whatever is possible to do."
Cubs manager Joe Maddon will continue to sort out the bullpen in the final 10 games. With Strop and Brandon Morrow both injured, left-hander Justin Wilson may be the leader as far as closer options.
