These have the potential of being really really great. Crop them tighter and you have a bunch of winners here. In the future, you may want to number your shots to make it easier for others to comment.
#2 just crop both players looking toward the umpire waiting for the call.
#3 Lose as much fence as you can and just focus in on the sliding runner and the catcher.
#4 Just the player -- lose as much fence and field and grass. Focus on the players emotions.
#5 Nice portrait crop here -- go tight.
On the home runs shots, crop tight enough to lose the guy watching along the fence and then lose the umpire as he crosses the plate.
Try that and your shots will become winners. These are quite good -- and will be better immediately.
Yeah, some real winners here but most are too loose. Give your subjects the more direct attention they deserve. It's hard to pick a favorite, but I'll have to go with the last shot. Nice work.
