Bean and Lu teamed to shoot a better-ball 12-under 60 in a steady, light rain Saturday for a 125 total and a one-stroke lead after two rounds of the Liberty Mutual Legends of Golf.
"We have one more round to play, but I'm sure I'll be getting a phone call from Jerry," Bean said with a laugh.
Is it possible Pate will have to find a new partner next year?
"I think I got a pretty good one right now," Bean said. "Yes."
John Cook and Joey Sindelar (65) shared the first-round lead and were alone in fourth place at 127 heading into Sunday's final round of the Champions Tour event at The Club at Savannah Harbor, an island layout in the Savannah River.
Bean and Lu started the day at 7 under, three shots out of the lead. Bean's birdie from 8 feet at No. 9 got them to 10 under at the turn and started their charge up the leaderboard. Bean holed out from 126 yards with a 9-iron for an eagle at No. 10. The duo birdied every hole after that until the 18th, where they settled for par.
Lu, a native of Taiwan, was an outstanding player in Asia who had to survive an eight-hole playoff for the final spot during Champions Tour qualifying school last fall.
"Good horse, man," Bean said of Lu. "He lasts a long time. Load the wagon."
McCallister and Tway made just two birdies on the front nine. But Tway hit a 3-wood to 20 feet and made the putt for an eagle at No. 11, then used an 8-iron from 157 yards for a hole-in-one at No. 15. It was the seventh ace of his career.
"It's obviously a lot of luck," Tway said. "You could hit a lot of good shots that don't go in and it happened to go in."
Winners of this event each will earn $230,000 of the $2.7 million purse.
