US Open champion Lucas Glover leads his three fellow 2009 major winners by two shots at the halfway stage of the PGA Grand Slam of golf.

Glover, who won his first major at Bethpage Black in New York in June, shot a six-under-par 65 at the 6,824-yard Port Royal Golf Course in Southampton.

He leads Open champion and fellow American Stewart Cink by two shots in the four-man, 36-hole tournament following a round which included one eagle, six birdies and two bogeys.

Cink's 67 contained five birdies and one bogey with Masters winner Angel Cabrera of Argentina five shots off the lead following a 70 and USPGA champion Y E Yang trailing in fourth place after a 71.
