Her struggles shooting the basketball didn't carry over into the game.
Cox, Lake's 5-foot-5 junior guard, had a tough time missing from behind the 3-point arc.
She matched her single-game record for 3-pointers made by sinking six en route to leading the Flyers to a 52-38 victory over the host Comets.
The victory clinched a third straight SLL championship for the Flyers, who also finished 12-0 in league for the third consecutive season.
"It's awesome, for three years in a row we have not lost a league game," said Lake coach Denny Meyer, whose team improved to 19-1 overall.
The Flyers made it clear they were going to defeat the Comets (10-2, 18-2) by scoring most of their points from behind the 3-point arc. They nailed 9 of 23 3-point attempts while only attempting 13 shots from two-point range, making good on seven of those shot attempts.
The Comets were 0-for-3 from 3-point range and 15 of 33 on two-point attempts.
Kaysie Brittenham and Carly Huston added 11 points apiece to help Lake's cause. Brittenham sank three 3-pointers, including two after halftime when the Flyers outscored the Comets 29-14.
Genoa, led by Alyssa Meis' 13 points, actually went into halftime with a 24-23 lead.
"It was a night of runs," Genoa coach Mike DeStazio said. "We kind of played even with them for two quarters and two minutes and then they made a run."
The Flyers outscored the Comets 15-6 during the third quarter, which included an 8-2 run to close out the period to give Lake a 38-30 advantage heading into the final eight minutes of action.
Brittenham nailed a 3-pointer to give Lake a 33-28 lead with 4:30 remaining in the quarter. Huston added a bucket off a Genoa turnover a few moments later to make it 35-28.
Cox drained her fourth 3-pointer of the night -- and second in the quarter -- to give the Flyers a 38-28 lead with 2:50 remaining.
A putback by Genoa's Bailee Adams with just over two minutes remaining ended a two-minute scoring drought for the Comets and made it 38-30.
Cox made four of her 3-pointers after halftime. With the Comets attempting to keep wraps on Brittenham, the league's leading scorer (19.3 ppg), it allowed for Cox to receive her share of wide-open looks from 3-point territory. She clearly made the most of the moment.
"In warmups I wasn't hitting anything," Cox said. "In the game, I just got the ball and shot it."
DeStazio credited Cox for meeting the challenge.
"It's not much you can say when a kid makes a couple of threes," DeStazio said. "It broke our back.
"I've got to give her credit. She was left open a little bit and she made it."
Jessica Feller added 12 points for Genoa, which suffered its two league losses against Lake.
