Nuno Borges vs Thanasi Kokkinakis — R128 — Cincinnati Open

Three breaks of serve in 36 return games left the tiebreaks to sort it, and Kokkinakis took both of the break points he saw while Borges went 1 for 6. The hinge came early in the second. Kokkinakis broke in game 2 for 2-0, Borges broke back in game 5 for 2-3, and the Portuguese, who won 59 of 67 first-serve points, was not broken again. The 30-year-old Australian, in on a protected ranking, hit 20 aces — 11 in the third set — saved 5 of 6 break points and won 19 games to 17, and still lost. He saved a match point before Borges closed it at 2 hours, 58 minutes, a second win over him in as many meetings on record.
