The Pirates' Zach Duke, who had already missed one start with an elbow strain, will go ahead and miss a couple more, MLB.com reports. Duke could come back within a week or two. An MRI found no structural damage, but Duke and the Pirates are probably right to proceed with caution - elbow injuries are never good news for pitchers. To replace Duke, the Bucs will look to one of a clump of subpar options that includes Charlie Morton, Brian Burres, Dana Eveland and Daniel McCutchen. So Saturday against Oakland, when Duke would have pitched, should be all kinds of fun.
