Cespedes, who was placed on the DL on May 12 retroactive to May 7, is still being bothered by a strained muscle in his left hand. Though he said his hand feels better than it did last week, Cespedes hasn't been able to swing a bat in his rehab. A's manager Bob Melvin said there's currently no definitive timetable for his return.
"It's going to be how he progresses as far as how his hand feels," Melvin said. "I think it's pretty obvious he won't play in this series, and then we'll just see. If he's at the point where the medical staff feels he's able to swing a bat and take some swings in the cage, then we'll probably start to have a better indication what the timetable is."
Cespedes had emerged as a power threat in his first season in the Major Leagues, and his absence has hurt the struggling A's lineup. The team has scored just 24 runs in its past eight games, hitting .193 in that span.
At the time of Cespedes' injury, his 21 RBIs and four stolen bases led all rookies, and his five home runs were tied for the lead. The earliest he could return now appears to be Friday, when the A's open a three-game series with the Yankees at home.
