Quentin hasn't played since July 26.
• First baseman Yonder Alonso, already done for the season with a right forearm strain, is probably headed down a path that will lead him to surgery, Black said.
"He's heading to that decision," Black said Saturday.
Alonso hit .240 in 84 games with seven home runs and 27 RBIs. He last played on Aug. 12 when he sustained the injury while preparing to hit. Black said the surgery would likely require a four-month recovery period.
