Surging Stan Wawrinka slammed down a solid win on Wednesday, powering into the French Open third round 6-3, 6-2, 3-6, 6-1 over German Dominik Koepfer.
The 2015 titleholder from Switzerland showed off the same big game which took him past Andy Murray in the first round without the loss of a set on the wet and heavy Paris clay.
After three-time grand Slam champion Wawrinka won the opening set, his momentum was established.
In the second, the 35-year-old hit a dozen groundstroke winners which more than accounted for near-perfect Koepfer’s three unforced errors.
No. 16 seed Wawrinka lost serve for the first time in the match as his opponent took a 5-3 lead in the third set, helped in part by 20 unforced errors off the Swiss racquet.
Wawrinka broke for 2-0 in the fourth set but missed on a pair of match points while leading 5-1.
He saved a break point before finishing the afternoon with a forehand drive.
