IT'S semi-final day at the WTA Finals in Singapore and two former champions go head to head.
Maria Sharapova, the winner in 2004 and current 7-5 favourite for glory with Boylesports, takes on 2011 champ Petra Kvitova who scraped through despite winning just one of her three group matches.
The other match sees Garbine Muguruza, making her first appearance at the Finals, look to continue her fine form of five consecutive top-10 wins. She is 8-15 at Boylesports to see off Agnieszka Radwanska, who has lost four in a row to the Spaniard and is 15-8 at Marathonbet to end that losing streak.
At the Swiss Indoors, Rafa Nadal hit back from a set and a break down to oust Marin Cilic yesterday and now tackles Richard Gasquet while the other semi-final sees Roger Federer take on Jack Sock.
There's second-round action from the European Championship darts, featuring Gary Anderson against Simon Whitlock and Stephen Bunting versus Dave Chisnall.
