Three-time Grand Slam champion Stan Wawrinka rolled back the clock with his vintage style of play as he thumped No.4 seed Daniil Medvedev in a five-set thriller at the Melbourne Park on Monday. The 2014 Australian Open champion Wawrinka got the better of tenacious Medvedev 6-2, 2-6, 4-6, 7-6(2), 6-2 in a match that lasted three hours and 25 minutes at the Margaret Court Arena.

“That was an amazing match and an amazing atmosphere,” Wawrinka was quoted as saying by the ATP Tour website after the match. “It was really tough to play against Daniil. I had to raise my level in the fourth and fifth sets. The level was super high and the atmosphere is always something special here in Australia.

“I’m finding solutions. I was losing a bit of confidence in the second and third sets and was fighting against myself to play my game. I had to fight, stay positive and I’m happy with the result.”

The Swiss has not won a title since pocketing the 16th of his career on the Geneva clay in 2017, with two bouts of surgery on his left knee pushing him to the brink of retirement.

Beating Medvedev brought up another milestone in Wawrinka’s illustrious career — it was his 300th Tour-level win. It was classic Wawrinka in the first set, with the 34-year-old playing some of his best tennis in a long time.
