BENTON HARBOR, Mich. (AP) — Richard Bland shot a 5-under 66 on Friday to set the target at the KitchenAid Senior PGA Championship in the Englishman's senior major debut.

Bland, who won his first DP World Tour title at 48, was at 12-under 130.

He had a one-shot lead over Scott Dunlap after the morning wave, and it looked as though it would hold up as the 36-hole lead. The second round was delayed in the afternoon by potentially dangerous weather, making it unlikely it would finish.

Chris DiMarco (65) was three shots behind. Among those still on the course, former Open champion Stewart Cink was at 6-under and still had seven holes remaining, including a pair of par 5s and a short par 4.

Bland has been leaning on his driving accuracy, even as he waits for his putter to warm up on the tricky Jack Nicklaus-designed greens.

He made his first bogey on the par-4 fourth when he failed to get up-and-down, and Bland considers the next hole key to his round — all because of a fly.

“As I was hitting my tee shot — literally as I was starting my downswing — a fly came straight across the ball,” Bland said. “I saw it and I hit it in the left trap. For that hole, I would've been reaching that, especially with it being downwind and off the right. I could have probably hit maybe even iron into that hole today.”

Instead, he had to lay up and then managed to get up-and-down from 130 yards for birdie.

Dunlap, who won earlier this year on the PGA TOUR Champions, was challenging for the lead with seven birdies until he lost a scoring opportunity by making bogey on the par-5 16th. He still posted a 65 and was not in the mood to complain.

“That's as good of golf as I've got,” Dunlap said. “Obviously, I won recently, so got a little bit of confidence, maybe figured a few things out. But my track record around here has been a little wanting, so I guess maybe I hadn’t used up any of good golf. It’s kind of all come out in these two rounds. See what we have left in the tank for the final two.”

DiMarco's highlight was holing out a bunker shot on the par-5 10th for eagle.

Defending champion Steve Stricker, who had never played at Harbor Shores, was 1-over for the round through 12 holes and eight shots behind Bland.
