French Open: Former champion Stan Wawrinka knocked out in round one

Former Champion Stan Wawrinka was knocked out of the French Open in the first round as he lost 6-2 3-6 4-6 7-6(5) 6-3 to Spain's Guillermo Garcia-Lopez on Monday.

The Swiss, who lifted the Musketeers Cup in 2015, led two sets to one but faded away after losing the fourth-set tie-break.

Seeded 23rd in Paris, Wawrinka has been finding it hard to make to the top again after undergoing two knee surgeries last year.
