Yep...today, it looks like a mistake to trust him. Sometimes a guy just don't have it....and no one will mistake him for JV. JMO.
When your fully rested starting pitcher gives up 4 runs in one inning, the problem is the pitcher's performance (and said pitcher's defense). Ironically, if someone told me Valdez would have 4 Ks and 0 walks through 2 innings I would have taken that.
