It's been a rough couple of years for Ryan Harrison, who hasn't been in the ATP Top 100 since the beginning of 2014. He's played qualifying and Challengers over that span, even made the semifinal of an ATP 500 last year, but hadn't found, partly due to injuries, the game that had gotten him into the Top 50 back in 2012. After getting through qualifying last week at the US Open, Harrison beat Adrian Mannarino of France Monday for his first slam main draw win since the French Open in 2013. Today Harrison, known for getting lousy draws at majors, faced a much tougher task in No. 5 seed Milos Raonic of Canada, a finalist at Wimbledon last month. Although Harrison was a clear underdog, he did have a previous win over Raonic to boost his confidence and Raonic proved to be out of sorts physically, leading to Harrison's 6-7(4), 7-5, 7-5, 6-1 victory.
Next up for the 24-year-old, in his first third round slam match, is Marcos Baghdatis of Cyprus, who defeated No. 32 seed Benoit Paire of France 6-2, 6-4, 3-6, 6-4.

Other US men to reach Friday's third round with wins today are No. 26 seed Jack Sock, who blew past qualifier Mischa Zverev of Germany 6-1, 6-1, 6-2 and No. 20 seed John Isner, who needed only one tiebreaker to beat qualifier Steve Darcis of Belgium 6-3, 6-4, 6-7(10), 6-3. Sock plays No. 7 seed Marin Cilic of Croatia on Friday, with Isner getting Kyle Edmund of Great Britain, who eliminated wild card Ernesto Escobedo 7-5, 6-4, 6-4.
The only US women to win today were those playing other Americans.
Seventeen-year-old CiCi Bellis made the third round of a slam for the first time tonight, coming back to beat Shelby Rogers 2-6, 6-2, 6-2. Bellis, who made the second round when she received a wild card as National 18s champion in 2014, will play No. 2 seed and Australian Open champion Angelique Kerber of Germany on Friday.
This year's 18s champion, Kayla Day, also won her first round match, beating veteran Madison Brengle when Brengle retired down 6-2, 4-2 on Monday, but she had no answers for the power of No. 8 seed Madison Keys, who blasted winner after winner in a 6-1, 6-1 victory. Next for Keys in Naomi Osaka of Japan.
The men's draw is here; the women's draw is here.
Doubles started today, with both USTA National 18s champions scheduled. JJ Wolf and John McNally were beaten by Chris Guccione of Australia and Andre Sa of Brazil 6-4, 6-4 and Ena Shibahara and Jada Hart lost to No. 7 seeds Sania Mirza of India and Barbora Strycova of the Czech Republic 6-3, 6-2.
NCAA men's doubles champions Mackenzie McDonald and Martin Redlicki of UCLA had a set point in the first against top seeds and Wimbledon champions Nicolas Mahut and Pierre-Hugues Herbert of France but fell 7-6(8), 6-1. NCAA women's champions Brooke Austin and Kourtney Keegan of Florida play Thursday against Asia Muhammad and Taylor Townsend.
