DJOKOVIC 6-1 4-6 6-1 6-4 - DJOKOVIC WINS THROUGH TO THE SEMI-FINALS! He is pushed to deuce by a determined Berdych, but Djokovic produces two powerful first serves down the T to close out the match in four sets and secure his place in the semi-finals of the Australian Open for the fourth year in succession! It's a very fine win from the top seed, and he roars with his arms aloft as he clinches the win!

DJOKOVIC 6-1 4-6 6-1 5-4 - Credit to Berdych, who battles through from 15-15 to hold in determined fashion as he at least forces Djokovic to serve out for the match in the fourth set. The Serb battles away furiously in an attempt to snatch the match away prematurely, but Berdych has just enough to hold.

DJOKOVIC 6-1 4-6 6-1 5-3 - Djokovic is utterly relentless as Berdych throws everything at his opponent but to no avail as he holds serve with a flurry of powerful groundstrokes and a serve down the T that clips the line! He is now just a game away from victory and a place in the semi-finals. Can Berdych at least hold to apply the pressure?

DJOKOVIC 6-1 4-6 6-1 4-3 - Berdych continues to battle extremely hard as he holds serve to 30 with three well-worked points to close it out after finding a big first serve. The Czech produces an emphatic smash down the line to take the game, but Djokovic remains just two holds away from a place in the last four.

DJOKOVIC 6-1 4-6 6-1 4-2 - Djokovic restores his two-game cushion as Berdych looks to be running out of time in this match. The Serb holds serve with relative ease, and he is finding his first serves with precision at the moment with Berdych having committed 42 unforced errors.

DJOKOVIC 6-1 4-6 6-1 3-2 - Djokovic is hugely disappointed as a hawkeye call goes against him at 30-15, and Berdych is relieved to come through another tough service game as he stays in touch with the top seed at just a break down. Can he challenge Djokovic on his opponent's serve now?

DJOKOVIC 6-1 4-6 6-1 3-1 - Djokovic has no problems in consolidating his break of serve as he drives a forehand down the line and manages to find two big serves outwide to pin his opponent back behind the baseline. Berdych has to find another gear, with his current approach just not troubling the Serb.

DJOKOVIC 6-1 4-6 6-1 2-1 - BREAK! Djokovic looks to be in total control now as he bludgeons a forehand down the line and forces the break of serve with Berdych utterly frustrated with his inability to hold under pressure since the second set. Djokovic has the break and the clear advantage now.

DJOKOVIC 6-1 4-6 6-1 1-1 - Brilliant rallying from Djokovic to go 30-0 up, sending his opponent all over the court before a forehand winner. An ace follows then a superb forehand drive which leaves Berdych standing. He levels and gets on the board at the first opportunity on serve.

DJOKOVIC 6-1 4-6 6-1 0-1 - Berdych forces his way to 40-15 with two tremendous volleys at the net, and a solitary forehand passing shot cross court from Djokovic is not sufficient. Berdych drills a powerful volley, then a smash, to close out the game in emphatic fashion! Can he now challenge Djokovic on the top seed's serve?

Can you see any way back for Berdych now, or will Djokovic continue to run away with the match? Should Berdych continue to come into the net, or give up on that tactic? Get in touch with your thoughts and predictions via Twitter -

DJOKOVIC 6-1 4-6 6-1 - SET! Djokovic is utterly clinical as he takes the third set in hugely convincing fashion, and Berdych is left shell-shocked as he trudges off to his chair. The world number one is back in control now, and Berdych has got to start the fourth set considerably sharper than he did the third if he is to take this match the distance.

DJOKOVIC 6-1 4-6 5-1 - Berdych belatedly gets on the board in the third set as he battles through to hold from 30-30, and Djokovic is absolutely gutted to lose even a single game! He now has the chance to serve out for the set, and Berdych will have to produce something very special if he is to compete.

DJOKOVIC 6-1 4-6 5-0 - This is a mauling in the third set as Djokovic racks up five games in the space of 19 minutes, and Berdych seems to have long since abandoned any hope of competing in this set. It's ruthless play from the world number one, but Berdych has been extremely flat since hauling himself back level in the match.

DJOKOVIC 6-1 4-6 4-0 - BREAK! It's all too easy for Djokovic in this third set as he breaks for a second successive game and establishes a hopelessly one-sided four-game cushion. Berdych lacks intensity after his exploits in the previous set, and he can only find three tame first serves as Djokovic breaks once more in clinical fashion. We've played just 17 minutes of this set!

DJOKOVIC 6-1 4-6 3-0 - Djokovic is rampant at the start of the third set as he consolidates his early break to assume a 3-0 lead, and he is utterly ruthless as he breezes through his service game with Berdych unable to challenge the world number one. He needs to arrest this slump and quickly! /// @Cazzykins86 believes Djokovic will win in five sets with Berdych making it very hard work for the top seed. What do others think?

DJOKOVIC 6-1 4-6 2-0 - BREAK! Djokovic is immediately into his stride with a powerful forehand winner down the line, and an exquisite lob over Berdych's head to post two break points at 15-40. Berdych saves the first with a brutal forehand cross court, but he cannot stave off the pressure from Djokovic as the Serb breaks to open up a commanding early lead in the third set!

DJOKOVIC 6-1 4-6 1-0 - Djokovic composes himself after looking absolutely furious with how he allowed Berdych to close out the second set courtesy of two unforced errors, and he manages to settle down and complete a very solid service hold to love to begin the third.
