At Delray Beach on Tuesday. He was hitting with NCAA champ Benedikt Dorsch. At one point the two were just doing constant baseline rallies and after about 15 mins. of non-stop hitting Dorsch looked like he was ready to lose his lunch. Agassi looked fresh. Agassi and coach Cahill appear to be working on heavier groundies (if you can believe that). His serve in last nights match was much improved. In one game he aced Mello three times and hit an unreturnable to close out the game. If you think you see Agassi hit some awesome shots during a match, you should see some of the stuff he does in practice. It's absolutely unreal! He hit some winners that where among the hardest shots I've ever seen. They played some practice games. Agassi won most of them, but Dorsch held his own, at least when serving. It was a blast to get to sit in on the session. Honestly, it looks like Agassi uses Cahill to bounce ideas off of more than anything else. It looks like Agassi is serious about giving it one last shot at trying to catch Federer. It will be an uphill battle for sure, but he's in tremendous shape and seems to be hitting really sharply. It's good to see him coming back so strong after a long layoff.
