Maholm's contract will look even better come July. If his ERA is as glossy as it was last year, at worst, they could get a mid-level prospect for him.
You would think that, and it may prove to be true, but if it is true, then you would also think it would have been true in 2011, when Maholm had an ERA of 3.06 on July 16th as the trade deadline approached, and the Pirates, who certainly could have used prospects or low salary talent still developing, instead held onto him.... perhaps because Maholm, for whatever reason, simply is not the kind of guy to draw much attention at the trade deadline.
I certainly hope it is because the Pirates refused offers or made outrageous demands and that Maholm brings some young talent in July... but the track record in 2011, indicates it might not happen in 2012, even if Maholm seems to be doing well.
I'm all for Wells becoming a situational righty once the rotation takes shape.
You generally want situational relievers to have a pretty dramatic split, and Wells does not. RH batters have an OPS of .714 against him for his career and LH batters have an OPS of .740. Just not a great deal of difference.
