Boca Raton, FL (SportsNetwork.com) - Michael Allen carded a 3-under 69 on Saturday and remained atop the leaderboard after two rounds of the Allianz Championship.
Allen, who fired a course-record 60 on Friday, ended two rounds at 15-under- par 129. He will go for his sixth Champions Tour title on Sunday.
Chien Soon Lu fired a 7-under 65 and jumped into a share of second place at minus-14. He was joined there by Scott Dunlap, who shot 67 in round two.
Duffy Waldorf had the low round of the day, a 9-under 63, which vaulted him into fourth place at 13-under-par 131. Jay Haas (64) and Tom Lehman (67) share fifth place at minus-12 at The Old Course at Broken Sound Club.
Wes Short, Jr. (68), Gary Koch (66) and Brad Bryant (67) are tied for seventh at minus-11, while Jeff Hart (66) is one stroke back at minus-10.
Allen led by three at the start of the round, but that cushion was gone before the turn. He started with five pars in a row before a bad drive on the par-5 sixth led to a bogey. He followed that with four more pars and was suddenly trailing.
Waldorf flew up the leaderboard with five birdies and an eagle on the par-4 seventh. That burst moved him to 11-under.
Dunlap, who was in the final group with Allen and Lu, started with birdies on the first, fourth and seventh to move into a share of the lead at 12-under. He was joined there by Waldorf, who got up and down for birdie on the par-5 11th.
Waldorf fell one off the pace as he bogeyed the par-3 14th. Dunlap birdied the 11th to take a 1-shot lead at 13-under. Allen birdied 11th and made it two it a row with a birdie on No. 12. That put him at 13-under.
Lu, who had five birdies in the first 13 holes, birdied the 15th to gain share of the lead. Waldorf made it a four-way tie for the lead as he birdied the 18th.
Allen ended a run of four straight pars with a birdie on the 17th. That gave him a 1-shot lead, and he kept that lead thanks to a 5-foot birdie effort at the last.
"I really kind of hung in there. I felt comfortable the whole way," Allen said. "It was hard. I felt like I was playing well. I was confident and I knew if I could hang in there I knew eventually things would turn around."
Lu 2-putted for birdie from just over 20 feet out to end one back. Dunlap, who had six pars in a row, closed with a 2-putt birdie at 18 to share second with Lu.
NOTES: Allen, the 2009 Senior PGA Champion, will go for his sixth Champions Tour win on Sunday ... This is the sixth time Allen has owned the 36-hole lead, and he has won two of the previous five, one of which was a team event, the Liberty Mutual Legends of Golf ... Lu and Dunlap, a tour rookie, are both looking for their first Champions Tour title ... Defending champion Rocco Mediate carded a 5-under 67 and he moved into a share of 14th at 8-under 136.
