This weekend brought two new #1's, more rankings chaos at 149, 174, and 184, and more than three dozen total upsets. Check out the biggest upset stories of the week, then read through the comprehensive list of all the upsets we could find. 

As always, if you see an upset we missed, please email david.bray@flosports.tv so we can be sure to include it. Now, here are the biggest stories of the weekend.

Brock Mauller Takes Out #1 Lewallen

The field at 149 has been parity-packed since the beginning of the season. All-Americans Brock Mauller and Boo Lewallen have been among the title contenders all year, but Lewallen occupied the #1 spot in the rankings when the two met on Sunday.

Lewallen led for most of the match, but Mauller tied it with a takedown late in the third period. He finished Lewallen off with another takedown in overtime and stopped Lewallen's unbeaten streak. We'll have a new #1 when the rankings come out on Tuesday.

#3 Kemerer Over #1 Hall in High-Scoring Affair

Three-time NCAA finalist Mark Hall was the clear favorite on Friday in his match with #3 Mikey Kemerer. He came out with explosive attacks, but Kemerer battled through Hall's positions and came out on top in a wild 10-6 match.

Kemerer's win will make him the new #1 at 174 and sets up thrilling potential rematches at the Big Ten and NCAA Championships.

Norfleet Notches Upset Over #6 Traxler

Arizona State fans have long believed that Kordell Norfleet was capable of greatness. While he's had brilliant moments throughout his career, he hasn't registered very many wins over highly ranked opponents.

He earned the biggest win of his career on Friday with an overtime victory over #6 Nathan Traxler. Stanford's Traxler could have the opportunity to even the series at the Pac 12 Championships, but for now, Norfleet is in control.

Norfleet's win could mean big things for Arizona State who is currently ranked #6 in the country but is vying for a top-four trophy.

#7 Griffith Stays Unbeaten, Knocks Off #5 Shields

Stanford was not without its own upset in the dual with the Sun Devils as #7 Shane Griffith Took out #5 Josh Shields. Griffith has put together an undefeated season so far with wins over #13 Ethan Smith, #10 Travis Wittlake, #9 Tanner Skidgel, and now #5 Josh Shields.

If Griffith remains undefeated through his conference tournament, he'll probably have another win over Shields which could reasonably earn him one of the top two seeds at NCAAs.

Go ahead @shanegriffith7 ???

Bucknell's Hartman Pins #8 Monday

The second top-10 upset at 165 came on Saturday when #20 Zach Hartman pinned #8 Kennedy Monday of North Carolina. Monday got the opening takedown, but a takedown, turn, and fall at the end of the first period gave Hartman the upset.

This win, combined with Hartman's pin of #16 Quentin Perez, demonstrates the danger that Hartman could bring into the post-season at 165.

184 Continues to be Chaotic.

The rankings chaos at 184 has been a recent topic of conversation on FRL and among wrestling fans on Twitter. The hierarchy in this weight class became less clear this weekend after another round of upsets.

At the top, #8 Abe Assad had two losses, one to #10 Aaron Brooks and a second to #14 Cam Caffey. This was one of two upsets for Caffey who also took out #13 Zach Braunagel. #9 Taylor Venz took his second loss in as many weeks, this time to #24 Rocky Jordan.

Rutgers' #23 Billy Janzer beat #15 Jelani Emberee, #19 Chris Weiler beat #16 Noah Stewart, and #21 Anthony Montalvo upset #17 Zach Carlson.

To recap, six of the wrestlers ranked between #8 and #17 were upset this weekend setting up an unpredictable postseason.

Cardani Bests #9 DeAugustino

The final top-10 upset of the week came at 125 where Illinois' Justin Cardani took out #9 Michael DeAugustino of Northwestern.

DeAugustino has been a pleasant surprise for the Wildcats this season as he finished third at CKLV and second at Midlands. That makes the Cardani upset all the more impressive.

DeAugustino has dropped a couple of bouts recently but will look to get back on track next weekend against Michigan State and Ohio State. Cardani's next action will be against #16 Nic Aguilar of Rutgers on Friday followed by Maryland's Brandon Cray on Sunday.
