For a 24-105mm lens, I think you did great. These must be significant crops, but the focus holds up well... the CA is heavy on the white edges. Nice action.
Easier to comment when pictures are numbered.
In #1, whites are a little hot, but you exposed well for his face. CA on his back thigh. Maybe a little late on the action, no ball, no eyes, but good dirt/chalk flying, which is always good to capture.
#2... again, good shot... Good fingertips, good dirt flying. A little late again, but I'm always guilty of that too... too much delayed reaction, not enough prediction. No ball. Cluttered background.
#3. Just OK. I like the manager's hand on the pitcher. I like the ball in his hand. But the mgr's face is obscured. And the background is very busy.
#4. Good job getting the ball in frame. A little loose, but understandable with your available lens. Good composition... outfielder on the left-third, ball on the right-third. Good background... I like the team URL.
