A proposal from the nation’s four largest conferences would give them more authority over rule-making, policy decisions and postseason events such as March Madness, Yahoo Sports reported Thursday.

The proposal, described as a “working document” ahead of next week’s NCAA convention, would grant the SEC, Big Ten, Big 12 and ACC rights to manage postseason championships such as the men’s and women’s basketball tournaments. Those events, worth more than $1 billion in revenue to the 1,100 schools of the NCAA, have long been run by the association.

The so-called power conferences already have existing autonomous legislative powers that separate them from other NCAA member leagues. They are seeking even more control as the distance between the Power Four and everyone else grows in terms of revenue and prestige.

The proposal, Yahoo reported, would create a new subdivision within the NCAA umbrella, a prospect raised by NCAA President Charlie Baker in December 2023. Baker’s plan, offered as a starting point for discussion, called for the creation of a new tier of NCAA Division I sports where schools would be required to offer at least half their athletes a payment of at least $30,000 per year through a trust fund.

COLLEGE BASKETBALL

Jackson Shelstad scored 24 points and made two free throws with 7 seconds left as No. 15 Oregon rallied late to beat Ohio State 73-71 in Columbus, Ohio.

Nate Bittle had 21 points, 8 rebounds and 3 blocks for Oregon (14-2, 3-2 Big Ten), which took a 70-67 lead on TJ Bamba’s shot in the lane with 40 seconds left. After Ohio State scored, Shelstad was trapped in the corner and turned it over, leading to two free throws by freshman John Mobley Jr. to give the Buckeyes a 71-70 lead with 12.6 seconds to play.

Shelstad raced the other way for a quick shot, and he was fouled before making two free throws to give Oregon a one-point lead. Bruce Thornton had a decent look at a 3-pointer from the top of the key, but it was short and Bittle secured the rebound.

Thornton led Ohio State (10-6, 2-3) with 20 points and Mobley had 16.

NO. 16 MICHIGAN STATE 88, WASHINGTON 54: Jaden Akins scored 20 points and the Spartans (14-2, 4-0 Big Ten) extended their winning streak to eight games by rolling past the visiting Huskies (10-6, 1-4).

MLB

Vladimir Guerrero Jr. and the Toronto Blue Jays avoided a salary arbitration hearing when the first baseman agreed to a $28.5 million, one-year contract on the day players and teams were to exchange proposed figures.

Houston left-hander Framber Valdez also reached a deal, an $18 million, one-year contract.

Guerrero and Valdez can become free agents after the World Series.

Left-hander Caleb Ferguson and the Pittsburgh Pirates agreed to a $3 million, one-year contract. The agreement is pending a successful physical.

The 28-year-old is 19-13 with five saves and a 3.68 ERA in 263 games with the Dodgers, New York Yankees and Houston Astros. Ferguson split time between the Yankees and Astros last season, going 1-4 with a 4.64 ERA.

The Pirates plan to stretch Ferguson out in spring training to see if he is an option to join the starting rotations. Ferguson has made 14 starts in his big league career, most as an opener.

SKIING

Lindsey Vonn was 10th fastest in a training run on Thursday for her first World Cup downhill in six years.

Three weeks after her World Cup comeback with a titanium knee at age 40 in a super-G, Vonn completed the 2-kilometer Karl Schranz course 2.55 seconds behind Federica Brignone of Italy.

The American star was clocked at 68 mph at a fast section of the hill where she won a downhill in December 2007.

A second practice is planned for today before the race on Saturday.

Vonn has won 43 World Cup downhills — a record for men and women — among her 82 career wins that is third on the all-time list. Mikaela Shiffrin, who is recovering after a crash in giant slalom last month, has 99 and Ingemar Stenmark won 86 in the 1970s and ’80s.

Brazilian star Marta, a six-time FIFA world player of the year, has re-signed with the defending National Women’s Soccer League champion Orlando Pride through 2026.

Marta scored 11 goals this season, one of her best with the Pride, including the game-winner in a 3-2 victory over the Kansas City Current in the semifinals.

Marta has 42 goals across 128 career appearances with the Pride.

On the international stage, Marta has played in six World Cups for Brazil and played last summer in her sixth Olympics, earning a silver medal after falling in the final to the United States.

Three-time Olympic champion Katinka Hosszu of Hungary, one of the greatest all-around swimmers, has announced her retirement.

Known as the “Iron Lady” of swimming for her gruelling repertoire of events, Hosszu, 35, competed at five Olympic Games. She was only 15 when she made her Olympic debut at the 2004 Athens Games.

Hosszu won her three individual gold medals in Rio de Janeiro in 2016, in the 100-meter backstroke, as well as her signature 200 and 400 individual medleys. She added a silver medal in the 200 backstroke.

She also won nine individual world titles in the long course pool dating to 2009 and still holds the long course 200 individual medley world record. She won 17 golds in the world short course championships.
