Pavin followed his opening 8-under 64 with a 70 to match Senior at 10 under. Senior had a 68.
Pavin had a two-shot lead with two holes left but bogeyed the 17th'his lone bogey of the day'and Senior birdied the 18th. Pavin is making his 35th career Champions Tour start, Senior his 48th.
I played solidly, Pavin said. I didnt get as much out of this round as I did (Friday), but it was difficult out there with the wind coming from a different direction.
Senior overcame a bogey on the par-5 first hole with five birdies on his last 13 holes. The Australian had a one-shot lead heading into the final round last year but shot a 77 and faded to 17th.
I have more confidence than I did this time last year because Im playing better, Senior said. I know Im close to winning.
Calcavecchia was 3 over after three holes, then finished with seven birdies. Hes shooting for his 12th consecutive top-10 finish on the Champions Tour. Don January holds the record with 36 from 1980-84.
I wasnt thinking about winning when I walked to the fourth tee, I can promise you that, Calcavecchia said. I have never been this consistent in my career. If I putt well, Im going to have a good chance.
Langer won at Broken Sound two years ago when he holed a bunker shot in a playoff with John Cook and lives just minutes from the course.Its going to take a lot of patience, Langer said. You need to try and hit as many greens as possible because its going to be difficult to get up and down for pars.
I didnt expect this, said Jacobsen, returning from his 17th surgery, a laser operation last November to remove bone spurs in his lower back.Defending champion Tom Lehman was 1 under after a 72.
