Rockies' Cook hurt, leaves in fourth
Cook, who has been bothered by a sprained big toe on his right foot that may have been the culprit in a mechanical flaw he discovered in his delivery, left after walking Nate Schierholtz on four pitches to start the fourth.
Cook labored through a 47-pitch outing, allowing four earned runs and three hits and four walks in three-plus innings. In his previous start, at Florida on Sunday, he allowed a season-high seven runs and eight hits in just 2 1-3 innings.
