Federer or SerenaIJ
After overtaking Roger Federer for most Grand Slam match wins in the Open era with 308, Serena Williams was asked who'll wind up retiring with more. Federer has 307 and can't increase that total until next season, because he is sitting out the US Open and the rest of 2016 because of problems with his surgically repaired left knee. "I don't know. We'll see," Williams said during an on-court interview after reaching the quarterfinals at Flushing Meadows on Monday. "Hopefully we'll both keep going. I know I plan on it. I know he does. So we'll see." Federer turned 35 on Aug. 8. Williams turns 35 on Sept. 26. With a 6-2, 6-3 win over Yaroslava Shvedova, Serena now owns more victories in Grand Slam matches than anyone else in tennis' Open era, surpassing Federer with her 308th.
Stan is the man
Two-time major champion Stan Wawrinka blew a lead, smashed a racket and eventually pulled out a four-set victory to reach his fourth straight US Open quarterfinal. After saving a match point in a five-set win in his last outing, Wawrinka was cruising against 63rd-ranked Illya Marchenko, who was playing in his first Grand Slam round of 16. Serving for the match in the third set, the third-seeded Wawrinka was broken and went on to lose a tiebreaker. After going down a break early in the fourth, Wawrinka took his frustrations out on his racket. He proceeded to win the next four games to regain control on the way to a 6-4, 6-1, 6-7 (5), 6-3 victory Monday. Marchenko had dropped the first set of his third-round match against 14th-seeded Nick Kyrgios but won the next two as the Australian struggled with a hip injury that eventually forced him to retire. Wawrinka next faces 2009 US Open champ Juan Martin del Potro, who beat him at Wimbledon this year.
