Acuna (hamstring) isn't expected to be activated from the IL until at least Sunday, Ian Quillen of MLB.com reports.
A rainout Friday for Triple-A Gwinnett put a bit of a hiccup into Atlanta's weekend plans for their star right fielder as he wraps up a rehab assignment. Gwinnett has a doubleheader scheduled for Saturday, and MLB manager Walt Weiss didn't rule out Acuna playing both ends of it. "There's a chance he'll play both," Weiss said Friday. "I think it's two [seven-inning games]. There's a chance he'll play both. He'll let us know when he feels like he's ready to go." Atlanta planned to have the 28-year-old back in the big-league lineup this weekend, so a Sunday activation remains possible. Acuna has been sidelined since June 9, and over 53 games for Atlanta this season he's managed a .794 OPS with seven homers and 15 steals.
