The Rockies enter Friday’s action at 39-42 in the National League West. They’re going to need a lot of things to go their way to make a second half run, which is exactly why they’re taking every precaution with their most promising young arm.
Jhoulys Chacin was originally slated to start tomorrow night against the Royals, but Troy Renck of the Denver Post reports that he has been pushed back to Tuesday against the Braves due to right forearm tightness.
Chacin told Renck he felt tightness when he was throwing curveballs in his last start Monday against the Cubs, which at least helps explain why he tied a career-high by giving up six runs on nine hits and three walks over five innings. However, the good news is that he has been able to play catch the past two days without incident.
Chacin, 23, is 8-5 with a 3.10 ERA through 16 starts this season. He has 92 strikeouts over 104 2/3 innings.
