Defending champion Jimmy Walker one-putted his last 11 holes Saturday on his way to an eight-under-par 62 and a two-shot lead at the Sony Open in Honolulu.
Walker putted like he did on Sunday last year at Waialae. That gave him a victory. This only gave him a chance to become the first player since Ernie Els in 2004 to successfully defend at the Sony Open.
With his 16th consecutive round in the 60s in Hawaii, Walker was at 16-under 194.
Matt Kuchar birdied two of his last three holes for a 68 and was two shots behind.
Walker had a share of the lead going into the final round at Kapalua last week in the Tournament of Champions and lost in a playoff.
Seeking a fourth title in eight years in Abu Dhabi, Kaymer shot a seven-under 65 in the third round to extend his overnight lead from one stroke to six. He moved to 20-under 196 overall -- a record-low total here after 54 holes.
The U.S. Open champion's pace was too hot for McIlroy, whose putting failed to match his tee-to-green play as he shot 71. The top-ranked McIlroy is eight strokes behind Kaymer and dropped from third into a share of fifth.
Thomas Pieters of Belgium shot 70 to stay in second and will play in the final group Sunday for the second consecutive day.
