Mike Hulbert and Bob Tway shot a 13-under-par 59 Friday to surge into a five-stroke lead at the halfway point of the $600,000 Chrysler PGA team championship at West Palm Beach, Fla.
Hulbert and Tway, runners-up a year ago, had 11 birdies and an eagle at the Palm Beach Polo and Country Club for a two-round score of 120.
The teams of Jeff Sluman-Robert Wrenn and Fred Couples-Mike Donald were tied for second place at 125.
Defending champions Gary Hallberg and Scott Hoch, who were tied for the lead with Hulbert and Tway after the first round, shot a second-round 66 and fell into a four-way tie seven strokes off the pace.
Sluman and Wrenn birdied five of the last six holes for a 63. Couples and Donald also shot a 63, making six birdies on their first nine holes.
