Holmes (fibula) might begin a rehab assignment in the second half of July, Tim Britton of The Athletic reports.
The right-hander has been sidelined since May 15 after taking a 111 mph comebacker off his leg. Holmes was having a career-best season as a starting pitcher when he was injured, posting a 2.39 ERA, 1.10 WHIP and 45:18 K:BB through 52.2 innings, and if he can get back on a mound within the next few weeks, he could be an enticing trade target for a contender as a rental -- Holmes has a $12 million player option on his contract he'll almost certainly decline.
