Jiri Lehecka beat Pablo Carreno Busta 6-1, 7-6, 4-6, 6-2 at the US Open, taking the first set in a burst and then closing decisively after Carreno Busta had pulled a set back. The Czech finished with seven aces and won 10 of his 14 service games, while Carreno Busta could not hit a single ace.
Lehecka surged to 5-0 in the opener before allowing one game back, then held on through a topsy-turvy second set that went to a tiebreak and took it. Carreno Busta hit back by winning the third 4-6, but Lehecka responded with two breaks in the fourth and wrapped up the match at 6-2.
Lehecka's first serve was the difference: he put only 58% in play compared with Carreno Busta's 73%, yet won 69% of points behind his first delivery and 42% of Carreno Busta's first-serve returns. His 5-4 edge in break-point conversions meant those numbers showed up where it mattered.
