The 6th seed and the former US Open semi-finalist Matteo Berrettini made a winning start in New York, beating Jeremy Chardy 7-6, 7-6, 6-3 in two and a half hours. Matteo lost serve twice and seized three out of ten break chances to prevail in straight sets, despite a great effort from the Frenchman.
Jeremy matched Matteo's winners, but he made too many unforced errors and lost ground in the decisive moments to propel the Italian through. Both players served well in the opener and reached a tie break after one loose service game from Berrettini.
From 5-3 down, Matteo claimed four straight points to claim the breaker 7-5 and gain a massive boost. Chardy led 5-3 in the second set and served for it in game ten, wasting a set point and allowing Berrettini to extend the action.
The Frenchman saved two set points at 5-6 to send them into a tie break, where he squandered a set point at 6-5. Matteo stole the breaker 9-7 and moved over the top with a double break in set number three. The 7th seed Denis Shapovalov toppled Federico Delbonis 6-2, 6-2, 6-3 in an hour and 49 minutes, dropping 19 points behind the initial shot and never facing a break point.
The Canadian stole the Argentine's serve six times and controlled the pace from start to finish to race into the second round. In the opening set, Denis grabbed five straight games and carried that form into the second to build a 4-0 advantage.
Shapovalov closed the set on his serve at 5-2 and played on a high level in the third to seal the deal with a double break on his tally. A qualifier Maxime Cressy stunned a two-time US Open semi-finalist Pablo Carreno Busta 5-7, 4-6, 6-1, 6-4, 7-6 after three hours and 33 minutes.
Young guns have made a winning start in New York.
Rushing to the net almost 100 times, the American went for all-or-nothing strokes and fended off four match points in the deciding tie break for a career-best victory. Maxime found his strokes in the third set and produced five commanding holds in the fourth to keep Carreno Busta under pressure.
Pablo lost serve once, and they went into a decider, deciding the winner in the tie break. The Spaniard built a 6-3 lead before squandering it, hitting a double fault at 6-5 and wasting the fourth match point soon after that following Cressy's incredible volley.
The American sealed the deal with a deep return at 8-7 that his rival failed to control to start a massive celebration and earn the third Major win.
