The 22-year-old Evans resident didn't find much competition in the season-opener at Mount Vintage Plantation, where he ran away from the field in the Sunbelt Nissan Golf Capital Invitational.
McKenney closed with even-par 72 on Sunday to finish at 3-under 141, which gave him an eight-shot victory over Lance Johnson (74 on Sunday).
McKenney has used up his golf eligibility at Georgia Southwestern State University in Americus, but he will return in the fall to complete his business management degree. He'll also turn pro, after playing as many amateur events as he can this summer.
He said he was shocked that he led by six shots after Saturday's first round. But he wasn't going to play conservatively in the final round.
"I just wanted to keep going lower," McKenney said. "If I try to play safe, I know I'll end up hurting myself. It worked out great on the front nine."
After playing his first seven holes in 3-under Sunday, McKenney had built a huge lead over Johnson, one of his playing partners.
At that point, he started to play the course, not an opponent.
"I knew this was a tough course; they had an LPGA event here. I wanted to shoot something very respectable to gain confidence to go into the summer," he said.
After a four-birdie, one-bogey round Saturday, McKenney had a more inconsistent day Sunday, with five birdies, two double bogeys and a bogey.
He closed out his round with an unlikely birdie on his 18th hole (the ninth hole on the original 18).
After a great drive with a 3-wood, McKenney missed his second shot on the par-5 so badly that it skipped across the water.
"I was so shocked at how bad I hit it, I thought it was kind of funny," McKenney said.
He still had 100 yards to the pin for his third shot. He knocked it eight feet from the hole, then made a hard-breaking putt for birdie.
McKenney has won his past two Regions Cup starts, but they are separated by more than eight months. After winning the event at Gordon Lakes in July, he didn't play again until the Golf Capital.
Senior division winner Kenny Larry kept a more current winning streak alive. Larry, who shot 77-71 to beat Greg Scurlock (77-75) by four shots, won the final senior event of the 2008 season, at Jones Creek.
Larry, 54, wasn't going to play in the Golf Capital because he didn't want to leave his wife on back-to-back weekends.
When next weekend's City of Augusta Match Play event was postponed to June 12-14, he was suddenly free this weekend. He signed up Thursday night.
"Everything had to work out perfect for me to play," Larry said. "It's really funny."
Larry took advantage of the opportunity, making up for a poor showing last year at Mount Vintage. There, he shot 79-81 and tied for 16th place, earning just five Regions Cup points. He had to finish strong at the end of the year (a runner-up finish and a win in the final two events) to overtake Glen Hurt and win the senior player of the year award for the second consecutive year.
"I was down from the start," Larry said. "This is a better start."
