Two games later, Djokovic locked up the victory when Musetti double-faulted. He paid tribute to del Potro by imitating his takeback forehand in celebration.
A round earlier, Djokovic set the record for most wins at the 1000 level when he surpassed Rafael Nadal with 411. The Belgrade native is bidding to lift his 100th career trophy and can move within two wins of achieving that milestone if he advances past Sebastian Korda.
The No. 24 seed fended off Gael Monfils, 6-4, 2-6, 6-4, to avenge his Indian Wells defeat to the Frenchman. In January 2023, Korda held a championship point on Djokovic before the legend battled back to clinch the Adelaide crown.
