Russia's Daniil Medvedev advanced to his first Grand Slam semi-final Tuesday at the US Open by defeating three-time major winner Stan Wawrinka while Roger Federer eyed his 46th Grand Slam semi-final berth. Fifth seed Medvedev's 7-6 (8/6), 6-3, 3-6, 6-1 triumph sent him into a Friday matchup against the later winner between Bulgaria's 78th-ranked Grigor Dimitrov and 38-year-old Federer, owner of a record 20 Grand Slam titles.
