Daniil Medvedev -05- (RUS) def  Stan Wawrinka -24- (SUI)
Match recap from Arthur Ashe Stadium announcer Andy Taylor.
Daniil Medvedev extends the win streak to 11. With a cramping left quadricept, he took-out 2016 US Open Champion Stan Wawrinka in four sets. In Ashe, the bellicose Russian found fans indifferent, rather than hostile. His previous two victories in Louis Armstrong Stadium included some memorable, sarcastic exchanges with fans…and a middle finger.
Like him or not, the dude’s a solid player. Two weeks ago, he won his first Masters-1000 title in Cincinnati, dispatching David Goffin in the championship match. The week before that, he fell to Rafael Nadal in Montreal’s Final. The week before that? Nick Kyrgios beat him in the Washington D.C. Final. This year he’s reached 6 Finals, won 2 titles, and owns more match victories in 2019 than any other player on Tour.
When you play deep into every tournament, who needs to book a practice court? He’ll simply rest-up for either Federer or Dimitrov…and his first career Grand Slam Semifinal.
