#5 Juan Martin Del Potro/Lucas Pouille/Kevin Anderson
The only contender who looks in great form is Juan Martin Del Potro. The World No. 8 is riding an 11-3 win-loss in 2018. Capturing the Acapulco title, The Argentine registered the biggest win of his career since Basel 2013.
With this 21st ATP title, Del Potro, who is riding a momentum, certainly will be the one to watch out for.
Of course, Lucas Pouille is in great form. A runner-up at the Dubai Duty Free tennis championships and also at the Open 13, the World no. 12 is 11-4 this season but it is doubtful if he can go to make a difference in the tournament. Kevin Anderson, too, is riding a wave but Anderson's 0-4 record against Federer suggests he isn’t quite equipped to derail Federer who is at the peak of his powers.
