PORT ST. LUCIE, Fla. (AP) — Jeff Schmid shot a 6-under 66 on Friday to open a four-stroke lead after the second round of the PGA Assistant Championship.

Schmid, a 45-year-old PGA assistant professional at Perche Creek Golf Club in Columbia, Mo., had a 10-under 134 total on PGA Golf Club's Wanamaker Course.

First-round leader Trent Rommann of Wichita, Kan., was tied for second with Brett Carman of Claysville, Pa.; Adam Gary of Bowling Green, Ky.; and Chris Trout of Fort Myers, Fla.

Schmid had eight birdies, an eagle, two bogeys and a double bogey.

"My scorecard was kind of a mess today, but a good mess for the most part," Schmid said. "I have hit the ball extremely well both days, made a few putts, and now here I am. ... It all comes down to the fact that you have to putt well out here to win. Hopefully, I can do that this weekend."

Schmid won the Golden Bear Tour's 2002 GBT Classic on the Wanamaker Course.

"I've played a lot of golf out here and actually had the biggest check of my career on this golf course playing on the Golden Bear Tour," Schmid said. "I know this is a place where I can make some birdies and feel confident that I can play well."

Carman, a PGA apprentice at Dogwood Hills Golf Course, had a front-nine 31 en route to a 68.

"I need to keep plugging away and give myself chances to make birdies," Carman said. "The golf course is in great shape and that should make for a great finish."

Trout had a 69, Gary shot 70, and Rommann followed his opening 67 with a 71.

Ashley Grier of Hagerstown, Md., the first female player in the event since 2011, was tied for 23rd at even par after a 73. She's playing the course at 5,941 yards, while the men are playing it at 6,971.

Jim Troy of Elyria, Ohio, had the shot of the day, holing a 5-iron from 213 yards for a double eagle on the par-5 seventh. He was tied for sixth at 5 under after a 69.

"The wind was helping a little bit from left to right and I hit a real solid shot that faded perfectly," Troy said about albatross. "It landed 10 feet short and trickled right in the hole."

The tournament winner will receive $9,000 and a spot in the PGA Professional National Championship in June in Myrtle Beach, S.C.
