Massy Kuramoto had the only under-par round with a 1-under 71 on Thursday to take the first-round lead in the Senior PGA Championship in cool, damp conditions on the testy Pete Dye Course at French Lick Resort.

The 59-year-old Kuramoto, a 30-time winner on the Japan Tour, is the chairman of the PGA of Japan and plays on the side, something he does well enough to have won the 2014 Japan Senior Open.

Kuramoto had a one-stroke lead over defending champion Colin Montgomerie, Billy Andrade, Barry Lane, Jean Francois Remesy and Bart Bryant.

Sweaters and rain jackets were the uniform of the day and scoring on the rugged Dye Course's twisting fairways and small greens did not come easily.
