GAME, SET AND MATCH!- FEDERER 6-7 6-4 6-1 CILIC. Roger Federer maintains his 100 per cent record at this tournament after coming from behind to sink Cilic in one hour and 54 minutes. The Swiss misfired off the backhand for long spells but eventually got the job done, serving out to love, to head into Saturday's semi final with another win. Cilic bows out with three straight defeats, despite being competitive throughout the week.

BREAK! - FEDERER 6-7 6-4 5-1 CILIC. The SABR makes an appearance and forces Cilic to try a lob attempt that drops just wide. It provides Roger with another break point. Cilic battles to save it but can't deny the Swiss when a second one comes along. Federer will now serve for the match.

FEDERER 6-7 6-4 4-1 CILIC. The 19-time Grand Slam champion stays well on course for victory with a routine hold to 15.

FEDERER 6-7 6-4 3-1 CILIC. Marin stops the rot as Roger starts to produce some party pieces. The Swiss makes deuce with the help of a sublime angled overhead off the backhand, but Cilic unloads the big serve when he needs it to get on the board.

FEDERER 6-7 6-4 3-0 CILIC. The Swiss Maestro consolidates to love and looks to have finally broken Cilic's spirit.

BREAK! - FEDERER 6-7 6-4 2-0 CILIC. Make that four on the spin for Federer! The Swiss senses the moment and gets the break with a supercharged return winner off the forehand. Cilic looks deflated.

FEDERER 6-7 6-4 1-0 CILIC. A good few moments for Fed as he makes it three games in a row and snares the scoreboard advantage in the decider. Does Cilic still believe? We're about to find out...

SET! - FEDERER 6-7 6-4 CILIC. We are level! Federer cranks up the heat - and Cilic can't handle it. The Croatian had been untroubled for much of the set, but wobbles all over the show at the worst possible time. Federer earns double break point and Cilic hands it to him with a wayward backhand approach that lands way wide of FedEx's left flank.

FEDERER 6-7 5-4 CILIC. An important hold for Roger after Cilic had posed a question with some good depth in the rallies to make 30-30. The Swiss has that scoreboard advantage and knows a break now will win him the set.

FEDERER 6-7 4-4 CILIC. How Marin must wish he had played like this in his previous matches at the O2. The Croatian did well in both of those, but this is a different level. His forehand has been painting lines and clipping corners all afternoon, while the serve has crunched into gear more often than not. The result here? A rather impressive love hold to level.

FEDERER 6-7 4-3 CILIC. Another service game, another solid hold. Are we hurtling towards a second-set TB or can one of these players halt the serving masterclass currenly on show?

FEDERER 6-7 3-3 CILIC. Federer spent a fair bit of time looking at the floor in contemplation prior to this service game. Whatever he was thinking doesn't result in a solution as Cilic canters to a love hold.

FEDERER 6-7 3-2 CILIC. A thumping forehand winner seals a similarly comfortable hold for Fed. A couple of quick-fire games fly by as if the players are already eyeing the business end of the set and are eager to get to it.

FEDERER 6-7 2-2 CILIC. Marin takes his ace tally to eight with more assured serving to easily move level.

Nice.
