Merida recovers from a set down to beat Rublev at US Open

Daniel Merida came from a set down to knock out Andrey Rublev 6-7 6-2 6-4 6-4 in the US Open round of 64, turning a tight opening tiebreak loss into three increasingly assured sets. The difference lay behind the second delivery: the Spaniard won 55.3 percent of his second-serve points, while Rublev managed just 34.0 percent of his and coughed up eight double faults. Rublev's raw firepower was there — 13 aces and 78.8 percent behind the first ball — but he landed only 60.2 percent of them. For Merida, it was a statement win over a marquee name on the sport's biggest hard-court stage.
