Mets vs Rockies @ Shea last week

I only just got back into photography recently (1-2 months ago) and picked up a 40D and an EF 100-400L. I went to Shea last week and took these pics. Any comments are welcome. As it got dim I had to increase the ISO and when I zoom in I can see some noise in some of the shots, but in order to keep a decent shutter speed to try and freeze the action I didn't have much choice (unless someone can tell me otherwise).

I had no problem getting into Shea with the gear, including a monopod, but I didn't use a large gear bag... just a regular backpack. My seats were on the field level but still a ways back....

Here are the pics...

I remember sitting in my dorm (USAF) in Korea in April 1999. Fernando Tatis cracked a grand slam and I was all pumped up as the Cards went on to score 3 more runs. Then they loaded the bases up and up comes Tatis. He jacked another one. Only player in history to hit two grand slams in one inning.
