Paul Casey showed a return to form in shooting a 6-under 66 Saturday to share the lead with Bradley Dredge after the third round of the Qatar Masters. The 32-year-old Casey arrived in Doha still feeling the effects of a lingering rib muscle injury and having missed the cut in each of his three previous appearances at the tournament.

But he made seven birdies along with a single bogey to sit tied with Dredge (70) with a 10-under total of 206. The duo will be chased by Lee Westwood in the final round, after the Englishman shot a 70 to stay one shot off the lead - despite cracking the head of his driver on the 11th tee. Under the rules, he was not allowed to have a replacement brought to him on the course.
