Emily: Absolutely cannot decide who I want to win this match. Nadal and Dimitrov both playing amazing tennis.
Kev: Unless bodies break down this is now about will to win, not ability. An area where Rafa was king - is the old Rafa really back?

The momentum is swinging backwards and forwards with every game. It seems each service game has been held under heavy pressure on each point. It's much more physical than yesterday's match too.
*Nadal 6-3 5-7 7-6 (7-5) 6-7 (4-7) 1-2 Dimitrov
A weird point at 15-15 as Grigor Dimitrov appears to turn an ankle as he chases back to retrieve a Nadal lob, but he turns, whacks a winner and seems right as rain as he prepares to serve once again.
A superb point at 30-15 as Dimitrov follows up the deftest pick-up half-volley with pin-point pass down the line.
A serve - rammed down the T - closes out the game.
Five-star stick-you-to-your seat entertainment.

*Nadal 6-3 5-7 7-6 (7-5) 6-7 (4-7) 0-0 Dimitrov
Grigor Dimitrov has a forehand at a brutally acute angle called out at deuce.

Nadal thinks the Hawk-Eye machine needs a reboot.
Dimitrov with a rather desperate drop-shot from behind the baseline offers up another break point.
Saved with a big serve that Nadal pats long.
If Dimitrov can get out of this game with his serve intact it will be a big mental boost for him. And a dent to Rafa's morale.

It seemed like Dimitrov was getting frustrated and lost some energy earlier in the set because Nadal was playing so well, but he found another level.

Who have you got in this then?
Even before the tie-break, Grigor Dimitrov looked the better player in the latter stages of that fourth set.
Nadal has the experience on his side. Dimitrov has youth.
Let's see.

Dimitrov is playing like a future Grand Slam champion without a doubt.

Cancel that dinner date. On we go.
Dimitrov misses the first chance to take this into a decider - he doesn't need asking twice.
