CASTLE ROCK, Colo. (AP) – The best part of Patrick Sheehan’s day was playing with Ian Leggatt and Chris Riley through the tall pines, thin air and steep hills of the Rocky Mountains – before the rains came.

“When you got two guys that you really like … it was a good group for me because everybody talks to each other and you’re telling jokes,” Sheehan said. “We all played pretty well (Thursday) and it just continued today. A guy makes a couple birdies and you just follow him up.”

Sheehan piggybacked on Leggatt’s incredible second round to take the lead at the halfway mark of the International golf tournament at Castle Pines Golf Club, the PGA Tour’s most novel event.

Seventy-two of the 140 golfers will have to finish the second round on Saturday.

Sheehan’s five birdies offset his two bogeys and gave him eight points for the day and 18 for the tournament, the only stop on the PGA Tour that uses the modified Stableford scoring system, which awards two points for a birdie, five for an eagle and eight for a double eagle. One point is deducted for a bogey, three for a double bogey or worse.

Stanford hangs on

LONDON, Ontario (AP) – Angela Stanford woke up after the second hole Friday in the Canadian Women’s Open. She would have been better off going back to sleep.

A day after matching the tournament record with an 8-under 64, Stanford birdied her first two holes – Nos. 10 and 11 – to reach 10 under and put herself in position to run away with her second LPGA Tour title.

“That was a lot of fun. I don’t know how it happened,” Stanford said. “I thought, ‘Wow!’ I felt like I was still asleep. I felt like I was still dreaming.”

On the par-5 10th, she two-putted from 40 feet after reaching the green in two with a 7-wood. Then on the 11th, she hit a pitching wedge to 3 feet.

“Hitting 10 in two. Even my caddie was like, ‘I never thought we were going to hit this green in two. No way,”‘ she said. “And then out of the bunker on 11. It was just kind of happening. I wasn’t thinking about it and then I started thinking.”
