Woods joins four rivals in lead at Orlando

ORLANDO, Florida (Reuters) - World number one Tiger Woods joined four opponents in first place at the Arnold Palmer Invitational after a four-under par round of 66 on Saturday.

Woods, looking for his ninth win in 10 tournaments, began the day seven shots off the lead but ended on six under-par with in-form Sean O'Hair, winner at Tampa Bay last week, who fired the best round of the tournament with his seven-under 63.

Bart Bryant produced his third consecutive two-under 68 to join the leading pack along with Bubba Watson and overnight leader and defending champion Vijay Singh.

Singh, who began the day on nine-under, had an eventful round with two bogeys and a double bogey inside his first seven holes but he recovered slightly to finish with a three-over 73.

The Fijian, who began the day on nine-under, had an eventful round with three bogeys and a double bogey inside his first eight holes but he recovered slightly to finish with a three-over 73 and a place at the top of the leaderboard.

Singh's topsy-turvy round was summed up by his performance on the par four 16th. Like a number of players he found water with his drive towards the green but after his drop he pitched in magnificently from the edge of the lake to save par.

But, once again, the outcome of this contest is in the hands of Woods.

A four-times winner, he had struggled with his putting on Friday, frequently ending short. But he was back to his clinical self with six birdies in difficult conditions with gusty winds, the highlights being two superb fairway shots for birdies on the tricky 15th and 16th, both par fours.
