On the driving range Thursday, during a rushed practice session before the team’s match against Reservoir, Glenelg’s Megan Kirkpatrick was growing worried. Nothing, not even her favorite club, was working.

“I only had about 15 minutes to warm up and I was hitting horrible, especially my 7-iron which is so odd because that is usually my comfort club,” Kirkpatrick said.

It turns out, she was simply getting all of her bad swings out of the way.

Over the ensuing couple hours, Kirkpatrick played nearly flawless golf on the way to making Howard County history at Cattail Creek Country Club in Glenwood.

She made five pars, three birdies and an eagle on the way to scoring a county-record 32 points (5-under par) under the county’s Modified Stableford scoring system that awards five points for an eagle, four for a birdie and three for a par.

Her round breaks the county’s previous mark of 31 points for boys or girls in a nine-hole regular season match. Atholton’s Bryana Nguyen was the previous girls record holder, having posted the four-under total on multiple occasions.

Kirkpatrick ended up breaking the record in memorable fashion, sinking an eagle putt on the par 5 ninth hole to punctuate her round.

“As soon as I saw the 8-foot putt I had left, I knew I was going to make it,” she said. “The boys team had played before us and all the people who had played, and the parents who were there, were lined up on the edge of the green. Usually this would make me super nervous but it was the most calm I have ever felt in golf.”

Kirkpatrick’s big day helped spark Glenelg’s girls to a convincing 68-31 win over the Gators. The Gladiators’ other scorers were Samadhi Tennakoon (18 points), Amber Kostick (14) and Norah Vanderpool (4). Reservoir got 16 points from Riyana Patel and 15 from Payton Pullen.

After the shaky range session, Kirkpatrick was able to put that in the rear-view mirror and immediately settle in with a par on the first hole and then a birdie on the second. It marked the first time she has ever been under par in a high school match.

She parred the next two holes to set up the turning point of the day.

On the par 4 fifth hole, a dog leg to the left around a large cliff, Kirkpatrick hit her tee shot off the rocks and got a lucky bounce back into the fairway. She took advantage of the break by hitting her next shot just a foot off the green — the only green she didn’t hit in regulation all afternoon — and then she sank the lengthy birdie putt from the fringe to go to 2-under.

“That definitely changed my perspective on the round,” she said. “I was no longer trying to [just] shoot a stroke or two under par, I really wanted to go low.”

Kirkpatrick hit a wedge to within six inches of the hole on the par 3 eighth hole for her third birdie of the day. And then she reached the par 5 final hole in two shots before sinking the putt to etch her name in the record books.

Kirkpatrick finished her round with just 13 total putts.

Glenelg (3-0) is currently one of three Howard County girls teams — joined by Marriotts Ridge and River Hill — still undefeated this fall.
