Novak Djokovic refused to let anything stop his pursuit of a record 25th Grand Slam trophy in the Australian Open quarterfinals. Not a problem with his left leg. Not an early deficit. And not the kid across the net,

Novak Djokovic produced a vintage performance to beat Carlos Alcaraz in the Australian Open quarterfinals on Tuesday, moving one step closer towards winning a record-breaking 25th grand slam singles title.

Djokovic’s four-set victory over his young rival sets up a semifinal with second-seeded Alexander Zverev and keeps alive his hope of a record 25th Grand Slam title.
