20-year-old Croatian Borna Coric knocked out Alexander Zverev in four sets in the second round of the US Open, leaving his quarter wide open. Zverev had been touted by many as a possible winner of the tournament – he was third favourite behind Federer and Nadal - so to crash out early was a surprise.

The man that can take advantage is Sam Querrey. The main threats in his quarter now are now John Isner and Kevin Anderson. Two men he has a positive head to head record against. The American has a newfound confidence on court this term and is on track to earn his highest end of year position in the ATP Rankings.  He’s also begun to beat the top players.

This season his record reads 4-4 against the top 10, which is the fifth best on tour. He reached the semi-finals of this year’s Wimbledon, beating the defending champion Andy Murray in the quarter-finals. The 6 ft 5 big server has also won two tournaments this year – the same amount as he has managed in the last 6 years – both on hard courts. In one final, he faced John Isner and the other, current world number one Rafa Nadal.

Sam Querrey to win his quarter at 12/5 is where the value lies and although Marin Cilic, a man he has never beaten, would likely be awaiting him in the semi-finals should he reach them, I'd back Querrey to chalk his first win on the board. At 33/1 an e/w bet on the tournament outright is certainly worth a punt.

Sam Querrey to win 3rd Quarter - 2pts @ 12/5
Sam Querrey Outright - 0.5pts e/w @ 33/1
