Nationals manager Dave Martinez said Friday that Williams (elbow) remains limited to throwing off flat ground, adding that it will "be a while" before the right-hander gets back on the mound, MLB.com reports. "He is feeling better, it's just been a slow process," Martinez said.

EDGE Analysis

Despite not heading into spring training with a guaranteed rotation spot, Williams was one of the Nationals' top pitchers over the first two months of the season, accruing a 2.22 ERA and 1.08 WHIP across his 11 starts. He was then diagnosed with a right flexor muscle strain in early June and has struggled to shake off the injury, as he's still not progressed to mound work two months later. Even if Williams is given the green light to throw bullpen sessions within the next few days, he'll still need several weeks to get fully stretched back out for starting duty. Williams doesn't look like he'll be a realistic option for the Washington rotation until September, and he might be brought back as a reliever if his rehab process remains slow over the next few weeks.
