Martin Kaymer takes control in PGA Grand Slam of Golf

Martin Kaymer has earned a two-shot advantage on the opening day of the PGA Grand Slam of Golf event in Bermuda.

The four-man competition also includes Rory McIlroy, Bubba Watson and Jim Furyk in a tournament reserved for the year's four Major winners.

Kaymer took control of the 36-hole challenge with a round of 66, which included an eagle and six birdies.

Masters champion Watson is two strokes back on four-under-par, while world number one McIlroy trails Kaymer by four shots.

Furyk, who was handed an invite due to McIlroy's victories in the Open Championship and US PGA Championship, struggled on the opening day as two late bogeys saw him finish his round on one-over.
