Though her individual match was now moot, it was aggravating for the junior. An ultimate competitor, she was just starting to hit her stride.
"I knew I could've pulled the match out," Krupp said of the match in which she lost the first set, 6-3, but led 3-0 in the second. "I wish I could've finished."
Krupp will never know how that match -- her toughest of the season -- would have turned out. Either way, The Augusta Chronicle All-Area Girls Tennis Player of the Year completed an undefeated season.
That being said, she and her teammates left Clayton County International Park unsatisfied. After advancing to the Final Four for the third consecutive year, the Lady Wolfpack fell in the semifinal round for the third time.
Though coming agonizingly close to a state title yet again still stings, six of the seven starters will be back next season.
With young players coming up and providing a challenge for starting spots, it's likely that next year's Greenbrier girls tennis team will be the best in program history.
"We all want it so bad next year to win the state title," Krupp said. "... If it was going to happen, it would be next year."
Krupp has developed her game through consistent tournament play and training at Petersburg Racquet Club. She's ranked No. 16 in the United States Tennis Association's Under-18 division for the state of Georgia.
Her coach at Greenbrier believes Krupp's mental game is just as impressive as her tennis strokes.
"A lot of players, their emotions show on the court," Brittany Jackson said. "She's one that pretty much holds it together, emotionally. She does get down on herself sometimes, but it's not something that other players see.
"She's very confident."
One thing's for sure: Krupp will be busy this summer doing everything she can to prepare for her final season.
On the weekends, she's traveling to and playing in tournaments. On weekdays, she has tennis practice from 10:30 a.m. until 5:30 p.m., with a lunch break in between.
She also teaches younger players in the program for nearly two hours each weekday morning.
"It's a different point of view seeing everything from a teaching perspective," Krupp noted. "You definitely see how it affects other people besides just yourself."
