If you have the inclination I would run levels on the bottom left shot, bring up the blacks to make for more contrast.
Your WB is a bit hot, which looks fine for baseball, looks like a very sunny day, but to my taste I would drop the Kelvin temp a tad, looks like it was sunny but your cam was on cloudy.
The wide angle stuff is very nice, compositionally
The expressions on the close-ups are very good.
the next time you are there, play around with your position (if you can at all) and your timing to see what you can do with that pitcher shadow- that is the kinda shots they use in a magazine as it has neat elements in there.
