Adam Walton vs Nicolas Mejia — R128 — Cincinnati Open

The return games separated it. Walton faced one break point all afternoon while generating nine, converting four, and after Mejia broke in game 3 for 2-1 the qualifier held just five of his nine service games. Three more breaks — games 1, 3 and 5 — carried the second set as Mejia's first-serve points won fell to 37%. In 1 hour, 47 minutes, the win ends a four-match losing run for Walton, his first since beating Nick Kyrgios in June.
