Michael:
Those are all good shots. Good crops as well. The only bad one is the left-handed batter--got to stay away from backs and butts, or so I've heard!
Focus is good, colors really pop! Nice job on the shortstop throw to first, too. #2 ... dead duck at 2nd unless that was ball 4 and sent the runner on a 3-2 count play!
I've shot baseball a few times and know the game incredibly well. You mentioned surfing and bike racing. Very predictable. Baseball = very UNpredictable.
I found it best to show up to a game and plan on coming away with a few types of shots. Might be the pitchers during delivery, pickoff moves to 1st, the hitters from the side of the plate with good light, etc.
This way, you're not focusing on the action as it comes at you at 100+ mph. You may be good enough to capture it, but it certainly didn't work for me. Stepped back and thought about it at bit. It made the most sense to me to plan on getting a few shots of this or that activity that routinely happens during a ball game and not focus on catching everything as it happens.
