World tennis number one Carlos Alcaraz has fought his way into the final of the Australian Open after beating Alexander Zverev in five sets in the last-4.
The Spaniard went 2 sets up before struggling with cramp.
Zverev was angered by Alcaraz taking medical timeouts but he pulled the game back to 2-all - before the top seed came from a break down to win in the fifth.
