I haven't noticed a big dip in velocity for Beckett. What I have noticed is that he doesn't have the same movement on his 2 seamer. This is important because it's such a nasty pitch for him that allows him to keep the ball on the ground for easy outs. Instead, hitters are elevating on him and knocking the ball out of the park. His curve is being left in the zone and it's getting hit hard. I think this is just a bump in the road for him and expect him to get back on track.
