BetMGM bonus code for college football and MLB on Saturday, September 6

After the NFL dominated our screens on Thursday and Friday, all eyes turn to the college ranks with another full day of college football, including a massive ranked clash between Oklahoma and Michigan. There are also 15 MLB games on the docket as baseball's regular season is in its final month, and the WNBA has two games on the schedule as well. 

Want to place bets on top college football, MLB or WNBA games on Saturday? Sign up with the BetMGM bonus code SPORTSLINE and get up to $1,500 in bonus bets if your first bet loses.

The BetMGM bonus code SPORTSLINE is only available to new BetMGM users who have never made an account before and who are of legal age in a state where the sportsbook is available. If you check those boxes, follow these steps to sign up:

If you're in Michigan, New Jersey, Pennsylvania or West Virginia, you can sign up with the BetMGM bonus code SPORTSLINE and get $150 in bonus bets if your first bet of $10 or more wins. If you're in another state where BetMGM operates, you can use the bonus code to get up to $1,500 if your first bet loses. There's no odds requirement for this wager. If you wager under $50 and the first bet loses, you get a single bonus bet slip equal to your stake. If you bet $50 or more and that first bet loses, you get five bonus bet slips, each worth 20% of your stake. Bonus bets expire after seven days and hold no cash value. A bet won with a bonus bet only returns the winnings and not the stake.

The top game of the day sees No. 15 Michigan head to Oklahoma for a date with the 18th-ranked Sooners at 7:30 p.m. ET. Each of these historic programs is coming off a down year by their lofty standards, but each entered 2025 with high expectations and enters Week 2 1-0. Michigan beat New Mexico 34-17, while Oklahoma defeated Illinois State 35-3. Each squad has a new quarterback, as the Wolverines have Bryce Underwood, a true freshman who was the top recruit in last year's recruiting class, while the Sooners went to the portal and got John Mateer from Washington State. Each will be key in this massive ranked clash, which could have College Football Playoff implications. The SportsLine Projection Model, which simulates every college football game 10,000 times, likes the Wolverines as road underdogs, as Michigan wins in over 50% of simulations at plus odds.

On the diamond, a key AL East matchup takes place in New York as the Yankees host the Blue Jays. Toronto has the best record in the American League, while New York holds one of three AL Wild Card spots. Toronto took Game 1 7-1 and can secure a series win on Saturday. Chris Bassitt (11-7, 4.10 ERA) gets the nod for the Jays, while the Yankees turn to Luis Gil (2-1, 3.68 ERA). Bassitt allowed two runs in six innings in his last start. As for Gil, the reigning AL Rookie of the Year missed most of 2025 due to injury and allowed two runs in 5.1 innings in his last start. The SportsLine Projection Model's top play for this game is the Yankees on the money line as they win in over 60% of simulations.
