Martin Landaluce vs Matteo Arnaldi — R64 — Cincinnati Open

Seeding was the only thing making this an upset: the market at 10Bet had the 20-year-old across the net as a 53 percent pick over the Cincinnati 31st seed. Arnaldi took the better share of the chances, converting 5 of 9 break points to Landaluce's 6 of 14, and lost serve six times in 15 games anyway while winning 38 percent of his second-serve points. The last break landed in game 9 of the third set, for 5-4, and the Italian saved a match point before the end. Landaluce had beaten Draper here two days earlier; this one ran 3 hours 59 minutes and sends him into the round of 32, a season that began at ATP No. 146 still climbing.
