Well, it is just one example, but tonight Horacio Ramirez led off the 3rd inning against Odalis Perez and popped a ball into the 2nd row on the 3rd base side. This ball would have been catchable in the past few years, but not anymore.
Anyways, he went on to single in his AB, starting the 5 run rally.
So yes, you are right, there is something to worry about here.
On the other hand, maybe they'll get some more run support....but I think I'd rather have the better ratios.
