Mannarino finds key to success in first round of US Open

After nine defeats in a row in the first round, Adrian Mannarino won a match against Borna Coric that will obviously do him the world of good. Between these two players who lacked benchmarks (the Croatian, 98th in the world, is not at his best either), the match was not flamboyant, far from it, largely dominated by unforced errors to the detriment of winning points (5 for the Frenchman in the first two sets).
