Garbine Muguruza is through to the last four of the WTA Finals with a 100 per cent record after coming through a dramatic encounter with Petra Kvitova in Singapore.

Muguruza - the first player to reach the semi-finals of the singles and doubles at this event since Serena and Venus Williams did so in 2009 - eventually triumphed 6-4 4-6 7-5 on Friday in a contest featuring 15 breaks of serve.

The second seed, guaranteed to progress once she won the first set, overcame an injury scare when rolling her right ankle midway through the match as she completed a third White Group victory.

Kvitova was left hoping Lucie Safarova would beat Angelique Kerber in straight sets later on Friday. Any other scenario would see the Czech eliminated.

Both players struggled on serve early and Muguruza was the first to break in game five when Kvitova sent a backhand into the net.

Kvitova hit straight back with a clean backhand return winner, but a wonderful forehand down the line set up another Muguruza break and this time she consolidated.

The Spaniard showed no nerves closing out the set, doing so to love when Kvitova sent a forehand return well long.

Breaks then came even more regularly in set two - only one of the first seven games going with serve.

Kvitova was the more aggressive player and twice seized the initiative after giving up the initial break, only for Muguruza to respond on each occasion before holding serve herself at the fourth time of asking - in the game that saw her roll her ankle.

Muguruza made a mess of two drive volleys in game nine, Kvitova subsequently gaining assistance from the net cord as she held for a 5-4 lead.

Having saved a break point to open up that advantage, the Czech then levelled the match as Muguruza sent a forehand into the net.

It appeared the earlier stumble might be having an effect on a frustrated Muguruza as she slipped 2-0 down in the third set, but she then won successive games to love before breaks were exchanged once more.

Another break at 5-5 then gave Muguruza the chance to serve for the match and she eventually converted her fourth match point, after saving two game points, to reduce Kvitova's chances of progressing.
