Serbian great Novak Djokovic defeated Sebastian Korda 6-3, 7-6(4) in a quarterfinal clash that was postponed from Wednesday and became the oldest ATP Masters 1000 semi-finalist in the series history.
At 37 years and 10 months, Djokovic is the oldest ATP Masters 1000 semi-finalist in series history (since 1990), surpassing Roger Federer, who reached the last four in Indian Wells and Miami at 37 years and seven months in 2019.
Djokovic, into his eighth Miami semifinal and a record-extending 79th at Masters 1000 level, will next face 14th seed Grigor Dimitrov, whom he leads 12-1 in their ATP Head-to-Head series.
The Serb, who is seeking his record-breaking seventh title in south Florida and a 100th tour-level trophy, is aiming to break his tie with Andre Agassi for most titles at the ATP Masters 1000 event.
