TIMONIUM, Md. — Tom Watson is feeling good and likes his golf game these days.

The 60-year-old Watson celebrated his one-year anniversary from successful left hip surgery by shooting a 6-under 64 and building a four-stroke lead Saturday at the Senior Players Championship.

Watson, bidding to become the oldest major winner on the Champions Tour, attacked the Baltimore Country Club course and put together a bogey-free round — he’s made only one during the tournament — with six birdies to finish at 12-under 198 and four shots clear of Loren Roberts (65), John Cook (65) and Mark Wiebe (66).

Watson nearly won the British Open back in July, but a balky putter on the 72nd hole cost him the Claret jug. Now, Watson said he’s more confident on the greens and, three months removed from his dramatic performance at Turnberry, happy about his play.

He’s also healthier. Last season, Watson walked with a limp and had trouble sleeping because of pain in his hip. After the surgery, Watson said he immediately saw results.

“I heard a lot of good things about hip replacement, people getting great results and having more flexibility, more range of motion,” he said. “I can get up on a horse, over a fence, all kinds of things now. It is something, to think you’ve got this metal, ceramic piece of merchandise in there. It works so well, I hope it lasts a long time.”
