The Syracuse native scored seven points during the pivotal 19-0 run that turned a four-point deficit into a double-digit lead and put the Cardinals in a hole they couldn't climb out of.
Stewart later swooped in for an incredible offensive rebound that she put back to make it 39-23. The Huskies led 48-29 at the half as Stewart had 18 points; the 19-point advantage fell four points short of the championship record set by Tennessee against Louisiana Tech in 1998.
"We rushed a lot, we started to panic a bit," Walz said. "They started executing."
UConn dashed any hopes of a Louisville comeback going on a 12-2 run after the Cardinals had cut its deficit to 60-44. The only question during the last 10 minutes would be whether this was the biggest blowout in title game history, and the Huskies easily surpassed Tennessee's 23-point win over Louisiana Tech in 1987.
The Huskies beat Louisville by 22 points in the 2009 title game. Louisville was trying to become the lowest seed to win a NCAA championship on the women's side. Villanova, as an eight seed, was the lowest to win it on the men's side back in 1985.
UConn hit 13 of its 26 3-pointers, including four by senior Kelly Faris, who finished with 16 points, nine rebounds and six assists.
The Schimmel sisters, who really carried Louisville in the tournament, had a rough go against UConn. Shoni Schimmel missed her first six shots and finished with just nine points on 3-of-15 shooting. Jude Schimmel was saddled with three fouls in the first half.
"We made a miracle run in this tournament and will always remember that," said Sara Hammond, who led Louisville with 15 points.
