Vijay Singh rebounded from a bad shot on the 17th to birdie the final hole Thursday and take a two-stroke lead after the first round of the U.S. Senior Open.

Still playing full-time on the PGA Tour at age 53, the big Fijian shot a 4-under 66 on a hot and humid afternoon at Scioto Country Club in suburban Columbus.

Singh pushed his tee shot right and bogeyed the par-3 17th. On the par-4 18th, he hit his second shot to 4 feet. The three-time major champion hit 13 of 14 fairways and 16 of 18 greens.

Miguel Angel Jimenez, Jeff Gallagher, Michael Allen, Gene Sauers and Glen Day shot 68.

Defending champion Jeff Maggert had a 70. He won last year at Del Paso in California.

John Daly also shot 70.

Bernhard Langer opened with a 73.
