Men's round-up: Richard Gasquet through, Juan Martin Del Potro bows out

The popular Argentinian had not played at one of the sport's four major tournaments since the Australian Open in 2014, enduring three operations on his left wrist in the intervening two-and-a-half years.

Del Potro showed form of old to knock out fourth seed Stan Wawrinka in the second round but was beaten 6-7 (4/7) 7-6 (8/6) 6-4 6-1 by fast-rising Frenchman Pouille.

The 22-year-old was ranked 90th in January but is now up to 30 and will climb further after reaching the fourth round of a slam for the first time.

The match was suspended on an ugly note on Saturday evening as Pouille, who had just taken a two sets to one lead, got into a discussion with the umpire and was unhappy at being told to "shut up" by Del Potro.

Del Potro would no doubt have hoped the overnight break could change the momentum but Pouille was the more consistent player and showed delightful touch at the net to break in the fourth game of the fourth set.

The Frenchman had never won a tour-level match on grass prior to beating Marius Copil in round one but looked fully at home on the surface and will play Bernard Tomic in the last 16 on Monday.

Seventh seed Richard Gasquet moved stealthily into the Wimbledon fourth round for the seventh time in his career on Sunday, finishing off Spain's Albert Ramos 2-6 7-6(5) 6-2 6-3.

The French stylist required only 31 minutes to seal victory on Court 18, having moved two sets to one ahead the previous evening against the world number 36.

Gasquet, who reached the semi-finals last year as he did in 2007, could face compatriot Jo-Wilfried Tsonga in the last 16 if he beats American John Isner.

His win was his 28th at Wimbledon, taking him to equal fifth on the all-time list for Frenchmen, level with Rene Lacoste.
