Colin Montgomerie is still on course for a hat-trick of Senior PGA Championship titles heading into the final round at Harbor Shores.

The 52-year-old Scot posted a three-under 68 for a 12-under 201 and lurks just two shots behind frontrunner Rocco Mediate.

Montgomerie, aiming to become just the third player in the championship’s history to win three in a row, will now compete in the final group as he seeks his fourth major title in the senior ranks.

“You know how much this tournament championship means to me,” Montgomerie said after attaining his target score of 68. “Obviously, my first 72-hole stroke-play win here in America and managed to repeat the feat last year. To come back here, I wanted to make a good showing of it. I really did. I wanted to come here and contend on Saturday night. And that’s what I’ve done.”

Mediate posted a 71 to keep his hopes of a wire-to-wire won alive.
