Juan Martin Del-Potro v Dominic Thiem
The Argentinian has struggled to rediscover the sort of form that saw him win the US Open in 2009 since he returned from a long injury lay off early last year, but he is showing signs that he could be on his way back to his best. Despite being a slight outsider in the betting in his last round match against world number 13 Roberto Bautista-Agut, he came out with victory in straight sets.
Dominic Thiem is enjoying one of his best years on tour to date, but the 24-year-old Austrian’s least favourite surface is hard court, where his win rate is just 58.14%, 15% less than his record on clay. In contrast, hard courts are where Del Potro thrives, and his win percentage at Flushing Meadows alone is 77.42%.
Their head-to-head record also favours the Argentinian 2-0. The 6 foot 6 big hitter can continue his love affair with the US Open into the quarter-finals.
Elina Svitolina v Madison Keys
Madison Keys had to dig deep in her last match against Elena Vesnina after losing the first set. She admitted the crowd helped her fight back, where she won eight of the last nine games to secure her passage into the 4th round. Standing between the American and her first US Open quarter final is 4th seed Elina Svitolina. The Ukranian is currently one of three players who can become world number one at the end of the tournament.
I expect momentum in this match to swing both ways, as 22-year old-Svitolina has to contend with a large crowd cheering on the world number 16 from Rock Island. The result is difficult to call and there is is value in the 11/8 on offer for the match going 3 sets.
