MADRID (REUTERS) - Andy Murray collected more points to aid his ATP World Tour finals qualification bid, when he fought back from a set down to beat Kevin Anderson 6-7 (3-7), 6-4, 6-4 in the quarter-finals of the Valencia Open on Friday.

A wild card at the Spanish indoor hard-court event, which he won in 2009, Murray is eighth in the race to secure a berth at the season-ending tournament in London.

The Scot will play top-seeded Spaniard David Ferrer, who is also eyeing a place at the Tour finals, or Brazilian qualifier Thomaz Bellucci on Saturday for a place in Sunday's showpiece.

Murray is attempting to qualify for the Tour finals for a seventh consecutive year and won the Vienna title last week when he came from a set down to beat Ferrer in the final.
