Updates from the second men’s semi-final in New York
Zverev takes out Khachanov in straight sets to make final
Andrew Lawrence: in praise of five-set tennis | Mail Bryan
If tonight’s match turns into another war of attrition, both men appeared seasoned for the task. Tiafoe has already spent 16hr 3min on court across five matches, the fourth-longest journey to a US Open semi-final since the ATP began tracking match times in 1991. Shelton is only slightly fresher at 15hr 41min. Tiafoe has played 19 sets and Shelton 20, with both coming through five-set quarter-finals. The difference is down to literal mileage: Shelton has covered 44,143ft during the tournament to Tiafoe’s 39,472ft.
A strong US Open for the American juniors is heading into the final weekend, with four US players – two boys and two girls – through to championship matches on Saturday.
