Lyles is said to be dealing with left hamstring tightness. The muscle has given him issues of late, disrupting what had been an excellent start to the season.
After joining the Pirates on an affordable, one-year deal, Lyles turned in eight starts of 1.97 ERA pitching. But he stumbled in his next outing and soon thereafter reported hammy troubles. Lyles has permitted 16 earned runs in his past 18 2/3 frames.
Despite the recent downturn, there’s still plenty to like about the 28-year-old’s work to this point. He’s averaging more than a strikeout per nine for the first time in his career while sustaining the swinging-strike increase he has shown in recent years. Lyles isn’t throwing as hard as he did last year but has found more and more success by shelving his once heavily used sinker in favor of his four-seamer and curve.
It seems reasonable to hope that Lyles won’t require too long an absence, though he’d do well to ensure the problem is behind him. Trouble is, the Pirates are already dealing with some tough injury and performance issues in the rotation. Just what the team will do to fill in isn’t immediately clear. The Bucs are already on the look for innings from outside the organization.
