“Obviously we’re trying to take precautions and give him extra rest,” Girardi said [when asked if he was concerned with Bartolo Colon's durablity]. “That is something that we’re trying to do. He had the one bad inning that really cost us (last night), but it’s something that we look at, yes.”
Colon got off to a great start this season. In 13 games, over 78.1 innings, he had just a 3.10 ERA and had a 4:1 strikeout to walk ratio. Since then he has been in eight games over 41.1 innings. His ERA is 3.70 over that span and his strikeout to walk ratio is barely better than 2:1.
His biggest problem has been command. There will be a huge difference in the results if a K:BB ratio drops a full two points. He just cannot control pitches in the zone like he used to be able to. That could be due to the injury, but it could just be general wear over the course of the season. Or it could be both.
Either way, the guy was one of the Yankees best pitchers before he got hurt. Since then he hasn’t been terrible, but it’s clearly not the same either. If the Yankees feel that they can do something to make him more effective than they need to do that.
