Thiago Agustin Tirante vs Jan Choinski — R128 — Cincinnati Open

This came down to a handful of return points. Each man broke twice in 18 return games, and Tirante edged the total count 123-118 across 241 points, his 20 aces to Choinski's 14 keeping every breaker inside one swing. Choinski put 80 percent of his first serves in play to the ATP No. 65's 60 and still lost, having struck first in the decider with a break in game 4 for 3-1 before Tirante broke back in game 7 for 3-4. He saved two match points along the way, then watched the last tiebreak go, 2 hours and 50 minutes in. Tirante carries on the hard-court form that produced a win over Taylor Fritz at the Canadian Open last week.
