From the age of 9 on, Stephenville’s Maury Shock has played the prestigious Texas-Oklahoma Junior Golf Tournament.

Late last month, the Tarleton State-signee left the event for the last time as a player — and as a first-time champion.

Shock rode the momentum from a red-hot second round — in which she shot a 5-under 67, her best tournament score ever — and held off a late charge from Haslet’s Chandra Alexander to win the Girls Open Championship by two strokes.

Winning the tournament was “something I dreamed about for 10 years,” Shock said, adding that the win still seems unreal.

Shock finished the three-day tournament with a 218, shooting a 76 to begin and a 75 to secure the win over a field of 85 players from all over the United States and Mexico. She was 13th last year, “about eight strokes” back, she said.

Winning the tournament on her last trip was a mixed bag of emotions for Shock. Though she was thrilled to win — and in dramatic fashion, no less, by draining a 15-foot putt on her final hole — she was also “definitely sad” about nearing the end of her junior career.

The last day was “very emotional,” she said, as it became clear that a chapter in her life was ending. She plans to attend next year’s tournament, if only as a spectator.

On top of all that, she had to hold off Alexander, herself a veteran of the tournament and a future member of the North Texas women’s golf team.

Shock and Alexander go way back, and their showdown provides a fitting end to their days as juniors.

“We’ve played it forever,” Shock said. They met at the tournament six years ago, and have become “great friends” since — “but everybody wants to come out on top,” Shock said.

And this time around, she did just that.

The pair were “back and forth all day,” she said. “But God blessed me for some reason and I came out on top.”

Shock entered the final round with a slim one-stroke lead, but Alexander leapfrogged her on the front nine.

In the end, it came down to one final 15-foot par putt for Shock — which she drained.

“I knew if I made that, I had won,” she said.

Of her personal best round the day before, Shock said she “was just having fun.”

“Even when I hit it bad, it was good,” she said. “I’d never played that well, and I was just enjoying it.”

She finished the day with six birdies, split evenly between the front and back nine.

Shock, who will join the TexAnns in the fall, said head coach Jerry Doyle was “extremely excited” about her accomplishment.

“He was so proud of me he didn’t know what to do,” she said.

The TexAnns won their first-ever regional title in May and finished fifth at nationals, capping a stellar season.

Shock said she was looking forward to joining the young TexAnns, adding that there are “many things to look forward to with the Tarleton golf team.”

She’s set to close out her summer by playing the Forth Worth City Junior Championship and the Texas State Junior Championship.
