Allen is one shot removed from Fred Funk, Brandel Chamblee and Loren Roberts. John Huston, Bob Heintz, David Berganio, Jr. and 1994 Tucson champion Andrew Magee are two back, following 66s.
This is the first time Allen has held at least a share of the lead since the first round of the 1993 Bay Hill Invitational.
Needless to say, Allen hasnt had an overabundance of success on the PGA Tour. He turned professional in 1984, and joined the tour in 1990. This is his 164th career tour start, having finished inside the top 140 on the money list but once (73rd, 1993).
A winner on the Buy.Com Tour (1998 Greater Austin Open), Allen is still seeking his first title on the primary circuit. His best finish is a tie for third, at this event and the Phoenix Open, both in 1993.
He finished tied for 12th in last year's U.S. Open, and earned his '02 card thanks to a tie for 19th in the Qualifying Tournament.
Allen would like to follow in the footsteps of Len Mattiace, who snapped an 0-for-219 streak at last weeks Nissan Open. Mattiace is riding that momentum this week, opening in 5-under 67.
Last years winner, Garrett Willis, shot 1-under 71.
