ONLY ONES: Johni Broome had 25 points and 14 rebounds, and Auburn beat Michigan State 70-64 on Sunday in Atlanta and completed a sweep of No. 1 seeds advancing to the Final Four. Auburn (32-5) earned its second Final Four trip, while No. 2 seed Michigan State (30-7) fell short in its bid to send coach Tom Izzo to his ninth national semifinal. Auburn’s only previous Final Four appearance came in 2019. The South Region champion Tigers, the top overall seed in the tournament, became the last of the No. 1 seeds to advance to the Final Four — joining Florida, Duke and Houston. It’s the first time all top seeds have reached the Final Four since 2008, which was the only previous year of all No. 1-seeded semifinalists since seeding began in 1979. And higher-seeded teams went 12-0 in regional semifinals and finals for the first time since the tournament expanded in 1985. Broome, right, fell on his right arm while attempting to block a shot with 10:37 remaining and left the game. The first-team All-America selection returned with 5:29 left, drawing an immediate ovation from Auburn fans. He had the elbow wrapped and sank a 3-pointer less than a minute later. — Associated Press
