I quite liked #2. The contrast between the sharp look of concentration on the players face, and the blurred components of the frame (hair, ball, and racket) give a great sense of intense concentration in motion.
I'm sure the shooting conditions were tough (bright overhead sunlight and players in visors/hats). The photos feel overexposed and washed out. Sports shooting (where you have limited control of shooting angles in relation to the light source) in those sorts of conditions is tricky. I'm not sure I have specific recommendations but it seems like there's room for improvement in your camera settings. Shorter exposure time immediately jumps to mind.
