Ricky Dimon of The Grandstand and Steen Kirby of Tennis Atlantic preview and pick the four best men’s singles matches on Tuesday at the French Open. The schedule includes Grigor Dimitrov vs. Jack Sock and Alexandr Dolgopolov vs. Nicolas Almagro.

(10) Grigor Dimitrov vs. Jack Sock

Ricky: Their only previous encounter (Stockholm last fall) will not soon be forgotten, mainly because Dimitrov hit two absolutely ridiculous winners on back-to-back points. He eventually overcame Sock 5-7, 6-4, 6-3. This one should be similarly competitive even though Sock is an obvious underdog. The American may be coming off consecutive first-round losses in Rome and Nice, but he captured a title on the red clay of Houston and played relatively well in Madrid. Dimitrov is looking vulnerable, with a modest 18-10 record on the season. The Bulgarian was last seen getting bageled in the third set against Fabio Fognini in Rome…
