Line: 8 IP, 3 H, 0 ER, 3 BB, 9 K; W, QS
My fantasy perspective: Chacin was a much-hyped sleeper pick coming into the season but who knew he'd become the ace of a Rockies' staff that had such proven winners as Ubaldo Jimenez and Jorge de la Rosa. Who knew he'd be leading the team in starts (13), innings pitched (87), wins (7), ERA (2.90) and strikeouts (74).
A few causes for concern going forward with Chacin would be an extremely low BAA (.197) and BABIP (.226), both likely a result of an extremely high GB% of 60.5%. Keep an eye on him as the temperature starts rising, humidity levels drop and balls start flying out of Coors Field.
