But he was the top player during the hard-court tuneup circuit and the title match at Flushing Meadows will be his fourth final in the last four events he's entered.
The 78th-ranked Dimitrov eliminated Roger Federer in a five-set quarterfinal and was a point away from taking the first set against Medvedev in their semifinal.
