In Response to Why is Beckett so Good this Year!?:
[QUOTE]He is throwing the Cut fastball for strikes?  Should other Sox pitchers throw it? The master is of course, Mariano Rivera thats all he throws. Thoughts?

Becket gave the answer himself on NESN.  He has lost his ability to throw a change-up and now he's got it back.  It's the single most important pitch after the heater.
