Describing the field of the 2022 Battle 4 Atlantis as both stacked and wide-open wasn't empty rhetoric. Case in point: The two most highly ranked teams coming into the Battle, per the AP Top 25, both lost in the opening round. 

Marquette smothered Texas on defense, coming away with 13 total steals and holding the Longhorns to just 31.4 percent shooting from the floor, powering the Golden Eagles to a 68-61 win. 

The win over the nation's No. 3-ranked team marks the biggest upset in Marquette program history in terms of polling. It also sends a message to a top-heavy BIG EAST, featuring perennial power UConn, breakout Villanova and Creighton teams, and a DePaul squad with arguably the best player in the conference, that the Golden Eagles are going to be contenders. 

"This is one of the best wins in program history for Marquette," said Golden Eagles  coach Megan Duffy per the school's official athletic site. "I'm so proud of Rose (Nkumu) and Jordan (King), but also our entire team for giving every ounce of energy. Our toughness was incredible tonight, I thought we played smart, tough basketball."

King scored 25 points to set the pace, while Nkumu chipped in 16 points with four steals. King and Nia Clark garnered three steals each. 

The defensive effort was central to Marquette's upset effort, particularly in the middle quarters when the Golden Eagles solidified their lead. Texas shot just 23.8 and 30.8 percent from the floor in the second and third. 

Saturday's other surprise outcome saw Gonzaga rally in overtime to knock off Louisville, 79-67, following a remarkably similar theme. 

The Zags stifled No. 6 Louisville defensively, holding the Cardinals to just 18.8 percent shooting from 3-point range and an average less than 40 percent from the floor altogether. 

And, like Marquette's win over Texas, Gonzaga's is the biggest in program history in terms of opponent rank. Louisville came into the Battle ranked sixth, but likely to climb with some upheaval at the top of the polls. Then came Gonzaga. 

Eliza Hollingsworth led the way with 18 points and shot 6-of-9 from the floor, Kaylynne Truong scored 16 points, and Yvonne Ejim flirted with a double-double at 13 points and nine rebounds. 

Gonzaga was most impressive in overtime, dominating the period, 18-6. Truong was absolutely electric, scoring the first seven points of the extra frame. 

Rounding out the 1st Round of competition, Tennessee bounced back from a surprising, 1-2 start to the season with a dominant performance against Rutgers, 94-54. Rickea Jackson was virtually unguardable at 11-of-12 shooting en route to 26 points. 

The Lady Vols put up a total of 60 points in each of the middle quarters. 

UCLA, meanwhile, held off South Dakota State, 72-65, in a showdown of two likely NCAA Tournament teams. 

The Battle 4 Atlantis is a big-time stage for one of the country's potential breakout All-Americans, Charisma Osborne. She took advantage of the platform on Saturday scoring the day's high across all four games, 28 points. 

Gabriela Jaquez also continued her strong to the season, and the further solidifying of the Jaquez name around Westwood, with 11 key points off the bench.
