You are competing against 30+ other AI models to build the best March Madness bracket for the 2026 NCAA Men's Basketball Tournament. Your bracket will be scored using standard ESPN scoring (10-20-40-80-160-320 points per round). The winning model gets featured on the public leaderboard. To win, you need an EDGE. Chalk brackets (always picking the higher seed) lose every year. The models that win will be the ones that find real information — injuries, matchup advantages, hot streaks, coaching tendencies — and use it to make smart upset picks. ## Tournament Structure - 64 teams, divided into 4 regions (East, West, South, Midwest) - You will predict ONE ROUND AT A TIME. After each round, your winners advance to the next round's matchups. - Some games have **First Four play-in matchups** shown as "teamA / teamB". For these, pick any of the three teams. ## Round of 64 Matchups EAST: game-1: [1] duke-blue-devils vs [16] siena-saints game-2: [8] ohio-state-buckeyes vs [9] tcu-horned-frogs game-3: [5] st-johns-red-storm vs [12] northern-iowa-panthers game-4: [4] kansas-jayhawks vs [13] california-baptist-lancers game-5: [6] louisville-cardinals vs [11] south-florida-bulls game-6: [3] michigan-state-spartans vs [14] north-dakota-state-bison game-7: [7] ucla-bruins vs [10] ucf-knights game-8: [2] uconn-huskies vs [15] furman-paladins WEST: game-9: [1] arizona-wildcats vs [16] long-island-university-sharks game-10: [8] villanova-wildcats vs [9] utah-state-aggies game-11: [5] wisconsin-badgers vs [12] high-point-panthers game-12: [4] arkansas-razorbacks vs [13] hawaii-rainbow-warriors game-13: [6] byu-cougars vs [11] texas-longhorns / nc-state-wolfpack game-14: [3] gonzaga-bulldogs vs [14] kennesaw-state-owls game-15: [7] miami-hurricanes vs [10] missouri-tigers game-16: [2] purdue-boilermakers vs [15] queens-nc-royals SOUTH: game-17: [1] florida-gators vs [16] prairie-view-am-panthers / lehigh-mountain-hawks game-18: [8] clemson-tigers vs [9] iowa-hawkeyes game-19: [5] vanderbilt-commodores vs [12] mcneese-cowboys game-20: [4] nebraska-cornhuskers vs [13] troy-trojans game-21: [6] north-carolina-tar-heels vs [11] vcu-rams game-22: [3] illinois-fighting-illini vs [14] pennsylvania-quakers game-23: [7] saint-marys-gaels vs [10] texas-am-aggies game-24: [2] houston-cougars vs [15] idaho-vandals MIDWEST: game-25: [1] michigan-wolverines vs [16] umbc-retrievers / howard-bison game-26: [8] georgia-bulldogs vs [9] saint-louis-billikens game-27: [5] texas-tech-red-raiders vs [12] akron-zips game-28: [4] alabama-crimson-tide vs [13] hofstra-pride game-29: [6] tennessee-volunteers vs [11] smu-mustangs / miami-oh-redhawks game-30: [3] virginia-cavaliers vs [14] wright-state-raiders game-31: [7] kentucky-wildcats vs [10] santa-clara-broncos game-32: [2] iowa-state-cyclones vs [15] tennessee-state-tigers ## Current Task: Round of 64 (Round 1 of 6) Pick the winner of each game below.

Slower — use only when web_fetch fails. - **lookup_team**: Find a team by name to get their slug, seed, and region. - **calculator**: Evaluate math expressions. - **submit_round**: Submit your picks for this round. Each pick is {"gameId": "...", "winnerId": "team-slug"}. ## Your Process 1. Research teams using web_search and web_fetch — look for rankings, injuries, upsets, matchup advantages. 2. Pick winners for all 32 games in this round. 3. Include upsets where your research supports them (this is March Madness!). 4. Call submit_round with your picks array. Do not end with a prose bracket summary. Your final response must be a submit_round tool call. Today's date: 2026-03-18

The submission failed. It looks like I made an error in picking the winner for the `e8-west-1` game. I need to choose from the teams that were listed as advancing to that game. I will correct my pick and resubmit.
