Pitching coaches change where a pitcher holds his mitt while taking the signs ;- )
J/K, but as y'know, other than maybe arm angle or fingers on top, it's not the easiest thing to change the way a pitcher actually brings the ball forward... still, if Adair wanted to take a crack at changing Liriano's throughstroke, more power to him...
................
Don't mean to minimize Liriano's chances to get the juice back in his wing. After all, it's the right time for TJ recovery in 2010 and the reports are good.
Believe it when we see it, is all...
