The eagles keep landing for Jason Dufner at Muirfield Village

DUBLIN, Ohio—With two second-round eagles including a hole-in-one at the par-3 16th, Jason Dufner has a chance break a longtime PGA Tour record for eagles in a tournament. Even better news for fans of The Duf: the 2013 PGA Championship winner looks ready to contend after a long slump.

Dufner posted a 133 total (66-67) to sit just a shot off Memorial Tournament leader David Lingmerth heading into the weekend. The hot start at Muirfield Village for one of the tour's more popular players follows an eight-place finish last week at the AT&T Byron Nelson Classic. Prior to that, Dufner's best finish of the season was a 17th place at the Honda Classic.
