Big win by Wawrinka over Rublev. When the season restarted, Wawrinka looked stale and unlikely to get back to anywhere near his best. Given he's 35 which was once a million and nine in tennis years, unless you were Ken Rosewall or Jimmy Connors, that wouldn't be that surprising. He's now up to a provisional 18 ranking, and if the results work out 1 more win could move him back into the top 16.
