Grigor Dimitrov rallied for a shocking upset of 20-time Grand Slam champion Roger Federer at the US Open, the lowest-ranked New York semi-finalist in 28 years advancing to face Daniil Medvedev. The 78th-ranked Bulgarian, who had dropped all seven prior meetings with Federer, on Tuesday made a dramatic fightback to defeat the Swiss third seed 3-6 6-4 3-6 6-4 6-2 at Arthur Ashe Stadium and will face Russian fifth seed Medvedev in Friday's semis.
I'm just happy, Dimitrov said. 'The only thing I was telling myself was to stay in the match. Physically I was feeling pretty good. I was hitting some shots against him that were hard to hit.'"This is Grigor's moment, not my body's moment," Federer said. Dimitrov broke Federer twice on the way to a 4-0 lead in the final set and the 38-year-old Swiss star had no effective reply, foiled by 61 unforced errors in falling after three hours and 12 minutes.
