I think if Roddick were to win any other slam, he needs to improve his break point conversion percentage and beef up his return of serve in both percentage and placement. Plus, maybe he needs to increase his diversity on first and second serves. Traditionally, his first serve is either a huge flat one down the T or a slice out wide, while his second serve is almost always a kicker to the backhand side. Personally, I think the body serve is always a good choice for Roddick as nobody wants a ball coming upwards of 140 mph at their chest. Now, aside from there being no Federer, Nadal, or Del potro, what does he need to improve in the offseason this year in order to win the AO in January?
