Former U.S. Open champion Marin Cilic has upset No. 5-seeded Andrey Rublev to reach the fourth round of the Australian Open.

The 33-year-old Cilic, who won the 2014 U.S. Open title and was a runner-up to Roger Federer in Australia in 2018, beat Rublev 7-5, 7-6 (3), 3-6, 6-3 in the last match completed on Day 6 of the year’s first Grand Slam tournament.

He went into the encounter with just one win in his previous 15 matches against Top 10 players and had lost his previous four head-to-heads against Rublev, but was dominant from the start.

Cilic will next play No. 9 Felix Auger-Aliassime, who won 14 of the last 16 games in his 6-4, 6-1, 6-1 third-round win over No. 24 Dan Evans.
