BREAK! - ANDERSON 6-1 6-2 5-7 6-7 2-5 SCHWARTZMAN. Wow! Anderson is broken yet again. Schwartzman will now serve for the match! There are going to be mental scars for Ando if he does lose this match. He was in complete control.

ANDERSON 6-1 6-2 5-7 6-7 2-4 SCHWARTZMAN. We have a hold! Schwartzman punches the air and looks towards his team. Is he on course for a sensational comeback victory her? Time to see what Anderson has left now.

BREAK! - ANDERSON 6-1 6-2 5-7 6-7 1-2 SCHWARTZMAN. Has Big Kev ever had such trouble on serve in one match? He looks to continue his rejuvenation at 30-15 but then comes unstuck. Diego takes the game to extend the run of breaks at the start of this decider.

BREAK! - ANDERSON 6-1 6-2 5-7 6-7 1-1 SCHWARTZMAN. Where did that come from? Ando appeared to have nothing left in the tank, but seems to have found a second wind. He rediscovers the brutal forehand and churns out a couple of winners to earn a much-needed break back.

BREAK! - ANDERSON 6-1 6-2 5-7 6-7 0-1 SCHWARTZMAN. Anderson needs to dig his way out of this mammoth slump sharp-ish. He looks like a beaten man as he is broken to 15 at the start of the decider.

SET! - ANDERSON 6-1 6-2 5-7 6-7 SCHWARTZMAN. It's a nightmare for Anderson. He double faults and that's the set. All square. Only Ando will know how if he goes on to lose this match.

TB LATEST: Schwartzman leads 6-0 at the change of ends. Anderson is all over the place. He's leaking errors and handing this on a plate to Diego.

ANDERSON 6-1 6-2 5-7 5-6 SCHWARTZMAN. Diego screams in delight as he hits back from 15-30 down to edge in front. It's the same situation as in Set 3. Can he break at the death again and take us to a decider? Penny for Ando's thoughts right now?

BREAK! - ANDERSON 6-1 6-2 5-7 5-5 SCHWARTZMAN. Lightning has struck twice! Anderson's serve goes missing and Diego takes full advantage. An audacious lob tees up triple break point and the Argentine turns in delight as Ando is broken to love and fails to serve out the match for a SECOND time.

ANDERSON 6-1 6-2 5-7 5-4 SCHWARTZMAN. Ando applies the heat from 40-0 down to get to deuce. He was rattled serving for the match last time and no doubt fancied getting it done without that pressure. However, Diego digs deep and will now look for lightning to strike twice...

ANDERSON 6-1 6-2 5-7 5-3 SCHWARTZMAN. Ando moves within a game of victory. It's not vintage serving, but he gets it done to 30 when Diego fluffs a forehand and picks up a warning for venting his frustration on the ball!

ANDERSON 6-1 6-2 5-7 4-3 SCHWARTZMAN. The No.11 seed stays on Anderson's heels with a solid enough hold to 30.
