Mackenzie McDonald

Four months separate Mackenzie McDonald from his last win, and a 4-6, 5-7 loss to Alex Michelsen in Washington sank him to 2-6 on the year. He landed 80 percent of first serves and saved three match points, but won 46 percent of points and converted two of ten break chances, his fifth straight-sets loss in six defeats.

His last win remains a 6-4, 6-2 over Jenson Brooksby on March 30, and the only set since came off Patrick Kypson at Wimbledon. The ranking tracks it: ATP No. 112 in January, No. 145 now, down 49 in a year.
