Zack Wheeler pitched three scoreless frames and struck out three in his rehab start Saturday for Triple-A Lehigh Valley.
Wheeler, coming back from thoracic outlet surgery, threw 38 pitches. His velocity was down 2.5-3 mph from last year, which might or might not be a concern. If he was trying to throw as hard as he could and only came in at 92-94 mph, that would be a problem. But if he was just easing into things, being down 2-3 mph sounds about right. We will just note that last year, Wheeler averaged 95.9 mph with his fastball in his first spring outing, which was practically a match for the 96.1 mph he averaged during the season. Wheeler is due to make two more rehab starts before being reevaluated.
