SEMI-FINAL TEE TIMES 0915 & 1345 Els v Singh 0930 & 1400 Curtis v Bjorn all times BST

Vijay Singh was taken to a second extra hole by Shaun Micheel before clinching his place in the HSBC World Match Play semi-finals.

The Fijian world number three trailed by two holes at the halfway mark and went as many as three behind on the 22nd hole.

Day two highlights

But four birdies inside five holes around the turn gave him the lead for the first time at the 10th, his 28th.

The players traded the lead to the 18th but after halving the first extra hole, Singh wrapped it up on the short 2nd after a wayward tee shot from his opponent.

Break-in shocks Micheel

USPGA champion Micheel played well in the circumstances after being kept up half the night following a burglary at his rented house on the Wentworth Estate.

Singh now faces Ernie Els in the semi-finals, but the reigning champion did not have things all his own way against Tim Clark.

He almost threw away a five-hole lead against his fellow South African before clinching victory by two holes.

Els survived a comeback by Clark

Els seemed set for a simple win after reaching the afternoon's 13th tee five up.

But he drove into the trees on the 13th and sand and woodland on the 15th as Clark won four in a row to take the match to the 18th.

Els finally sealed an unconvincing win with a par on the final hole.

Thomas Bjorn eased into the semi-finals with a 5&4 victory over Masters champion Mike Weir.

The British-based Dane, seeded 10th, led Canada's number two seed by three at the 18-hole stage.

He went on to close out the match on the short 14th, his 32nd hole.

Bjorn, the Open runner-up, was pegged back to level at the 10th in the first round but birdied five holes after the turn to take control at lunch.

He then cruised to six-up and not even a Weir eagle at 12 could delay the end.

Bjorn was rarely troubled by Weir

Bjorn now faces Open champion Ben Curtis who proved his class by claiming an impressive 5&3 victory over Chad Campbell.

Curtis fought back from two down to lead the morning session by one thanks to an eagle on the final hole.

Campbell managed to get back on level terms but only briefly as Curtis used his sand wedge to great effect to win the afternoon's fourth and sixth holes.
