Grigor Dimitrov beat 17-time Grand Slam champion Roger Federer in an exhibition match at Madison Square Garden on Tuesday in a confidence-building victory for the younger player.
Dimitrov won 6-2, 1-6, 7-5, rallying from a break down in the final set.
The 23-year-old Bulgarian is 0-3 in official matches against Federer, who’s nearly a decade older.
Dimitrov broke Federer’s serve in the final game to clinch the match.
Earlier, Gabriela Sabatini, 44, beat Monica Seles, 41, in a pro set 8-5. Both have rarely played since retiring, but they decided it was worth training to commemorate the 25th anniversary of their classic five—set 1990 WTA Finals match at the Garden, won by Seles.
