Britain's Andy Murray went out of the Miami Open as he lost 6-7 (1-7) 6-4 6-3 to Grigor Dimitrov in the third round.
Scot Murray, 28, was on course for a place in the last 16 when he took the first set on a tie-break.
But Bulgarian Dimitrov, the 26th seed, came back to oust Murray, a two-time winner of this tournament.
Earlier, Johanna Konta became the first British woman to reach the quarter-finals in Miami, but Heather Watson lost to Simona Halep.
Konta, 24, needed just 34 minutes to take the first set against Romania's Monica Niculescu.
