Other than the 2nd serve, I found myself unable to think of anything else Andy could improve in the coming matches.
The 2nd serve is a massive liability though, and it's the one thing his upcoming opponents will be focusing on.
Forget modesty, Joao Sousa will be rolled over.
Upping his average 1st serve speed by an extra 10mph+ would help, not to mention his 2nd serve but for a first round it was good. 77% 1st serves is excellent but he hit under 100mph on average. His percentage was really good during Brisbane so I wonder if this is something he'll continue with.
