SHANGHAI (AP) - U.S. Open champion Rory McIlroy increased his lead to three strokes with a 7-under 65 in the third round of the Shanghai Masters on Saturday.

The 22-year-old Northern Irishman made seven birdies in another bogey-free round on the Jack Nicklaus-designed course at Lake Malaren in the outskirts of Shanghai to finish at 18-under 198 overall.

American Anthony Kim moved up a spot to second after hitting three consecutive birdies to close out the front nine followed by another four on the back nine to match McIlroy's 65. His only misstep was a bogey on the 18th hole.

South Korea's Noh Seung-yul was one stroke behind Kim at 14-under after following up his second-round 63 with a 67.
