And even if it isn't eminantly clear, isn't it possible Liriano's problem's were not entirely on him, but perhaps those coaching and instructing him held some blame? He came up as a rookie and was lights out using a healthy dose of his slider at the expense of his fastball. He got hurt and the team asked him to stop using the slider excessively and he struggled. He signs with the Pirates and he's back to using the slider as mush as his heart desires and again the fastball is the pitch that takes a hit. The increased slider, decreased fastball did happen one other year in a Twins uniform, his seemingly resurgent 2010 season. Why they made him alter his approach the following season is puzzling. Obviously the talent has been lacking in the rotation lately, but still, if for the past half decade you have more starting pitchers underachieve than overachieve, there might be a coaching/stratagy issue.
