Kaupulehu, Hawaii ? Tom Watson birdied six holes on the back nine for a 6-under 66 and a two-stroke lead Saturday over senior newcomer Fred Couples after the second round of the Champions Tour’s season-opening Mitsubishi Electric Championship.

The 60-year-old Watson, coming off a win with Jack Nicklaus in the Champions Skins at Kaanapali, overcame a rocky start and finished with nine birdies and three bogeys for a 15-under 129 total. Couples, who shot a bogey-free 66, is making his first official Champions Tour start on a sponsors exemption to the winners-only event.

Tom Lehman had a 67 to join Michael Allen (66) at 12 under.
