Before Louis Gagne teed off in his final regular season tournament at Orlando Christian Prep, his coaches jokingly said they expected a 29 out of him.

Little did they know, Gagne had one better in store.

He carded an 8-under 28 on nine holes, shooting what opposing coach Justin Johnson of Lake Nona High School called "the greatest nine-hole round I have ever seen."

It could have been a 27, too. Gagne rolled a 25-footer on his final hole and watched on as it just lipped out.

Gagne made two eagles, four birdies and three pars at the par-36, 3,286-yard front nine at the North Shore Golf Club in Orlando, Fla.

"I struck the ball the same, but yesterday my putting started to click and I made everything," Gagne said. "I really thought that I could make (the putt on No. 9) because the hole felt like a big bucket."

The high school senior drove the green on the par-4 first hole, reaching the putting surface about 260 yards away with a 3-wood. He made a putt for eagle, starting his round at 2 under. His second eagle of the day came at No. 5, where he chipped in from off the green.

He ended up beating out his teammate by nine strokes for the win and topping his previous nine-hole best by three strokes.

Gagne is a class-of-2015 LSU commit and the No. 28 player in the Golfweek/Sagarin Junior Ranking.
