Will Djokovic win his 10th Australian Open title on Sunday?

He launched to the side to return a ball and he apparently strained his left hamstring.

He quickly sought medical time out, receiving physiotherapy and then he returned with seemingly good mobility to defeat Medvedev by two sets to love.

Medvedev was not convinced that Djokovic's vague pain justified gaining a medical time out and he mocked Djokovic by pointing to his own thigh as he sat on the bench.

But in the final that followed, Djokovic had to struggle against his younger opponent, Korda.

He lost the first set and he had to save a championship point in the second set and had a medical time out again, before winning against Korda to become the 2023 Adelaide International 1 Champion.

At the time of the writing Djokovic has reached the quarter finals after beating Alex de Minaur. He has reached this round with his left thigh heavily strapped and with a number of medical times out.

Now the road to winning the championship becomes increasingly difficult for Djokovic.

Several players in the remaining eight may have enough all-round technical skills to seriously challenge him.

There are perhaps two main factors that may determine whether or not Djokovic will become the champion.

The first is the seriousness of his injury. If it does not deteriorate further, Djokovic may win.

I watched Djokovic's level of mobility throughout his third round match against Dimitrov and it appeared to be adequate. Indeed, without good movement he may not have beaten his hard fighting opponent in three straight sets.

But if his hamstring injury progresses to become high grade, it will sabotage his game, no matter how much he would try to apply mind over matter.
