Andy Murray has reached the US Open final in four sets, winning by a scoreline of 5-7, 6-2, 6-1, 7-6 (7).

One mistake from The Bird (Berdych) could land him in an exit row from the semifinals.

Berdych won a game! He is now down 3-1 and is looking to break back to breathe some light into this match.

Andy goes up 3-0 in the fourth (and most likely, final) set. Who would've guessed that?! Berdych has faded very quickly and a five-setter happening would be an upset.

Murray has done a great job of climbing his way back into the match after disappointingly dropping the opener.

Andy holds at love and closes in on a 5-1 gap.

And Berdych is on the board! There is still an improbable chance of him coming back in this set from 4-1 down but he is giving a valiant effort.
