I'll echo the welcome message.
Here are my thoughts: first of all, if you're looking for comments, it's a LOT better to number your shots. Secondly, a lot of these look a little hot, or overexposed. I tried to check out your EXIF but it has been stripped.
Look at the pinstripes on Soriano's uniform (if you can). They pretty much disappear into the white of the fabric, as you've blown out the highlights.
In general, a shot of the back of a player isn't ideal (the first one of DeJesus) unless they're doing something interesting, and like Ted said, if you're going to shoot pitchers or batters, you normally want to get the entire body in frame. You have a lot of shots of players kinda standing around not doing much. Any reason for this? Your pitcher shots would be better earlier in the delivery Vs. the follow-through. Also, on the shot of Outman, the player in the background ruins the image.
Hope this helps.
