BetMGM promo code for NFL, MLB, WNBA and more on Saturday, August 23

The NFL preseason wraps up on Saturday with 10 games on the schedule. Additionally, Saturday features a full 15-game MLB slate as well as three WNBA games. Top games on Saturday include Rams at Browns, Red Sox at Yankees and Liberty at Dream.

If you want to place bets on any of Saturday's games, check out the BetMGM bonus code SPORTSLINE, which gives new users up to $1,500 in bonus bets if they lose their first bet.

The BetMGM bonus code SPORTSLINE is available exclusively to brand-new BetMGM users. You must be 21 or older to sign up, and you have to be in a state where BetMGM's sportsbook operates. Follow these steps to sign up:

If your first bet wins, you get the winnings and stake like normal. If it loses, however, you will receive bonus bets equal to your stake up to $1,500. If your first bet is under $50, you get one single bonus bet slip equal to your stake. If your bet is $50 or more and loses, you get five bonus bet slips, each worth 20% of your stake. So if you bet $500 and lose, you'd get five $100 bonus bet slips. Bonus bets expire after seven days and can't be withdrawn, as they hold no cash value. If you win a wager using bonus bets, you get the winnings but not the stake.

There are 10 NFL preseason games on the schedule for Saturday, starting at 12 p.m. ET when the Ravens visit the Commanders and wrapping up at 10 p.m. ET when the Cardinals host the Raiders. Other games on Saturday are the Broncos at Saints (1 p.m. ET), Rams at Browns (1 p.m. ET), Colts at Bengals (1 p.m. ET), Texans at Lions (1 p.m. ET), Seahawks at Packers (4 p.m. ET), Jaguars at Dolphins (7 p.m. ET), Bills at Buccaneers (7:30 p.m. ET) and Chargers at 49ers (8:30 p.m. ET). A few teams are worth keeping a close eye on this weekend. One of them is the Saints, who have yet to name a starting quarterback for Week 1. Spencer Rattler, a second-year player, started the team's first preseason game while second-round rookie Tyler Shough got the nod in the second preseason contest. Rattler again gets first crack this week against the Broncos. The Browns have named veteran Joe Flacco as the team's starting quarterback, but who knows how long that will last. The team also has Kenny Pickett, Tyler Huntley and rookies Dillon Gabriel and Shedeur Sanders on the roster. Sanders didn't play last week but is expected to this week against the Rams, so keep an eye out for how he and Gabriel perform after Flacco is removed from the game. The Seahawks have their new starting quarterback in Sam Darnold, but he won't play against the Packers, nor will his backup, Drew Lock. Instead, Seattle will start rookie third-round pick Jalen Milroe, who will play the entire game.

The Kansas City Royals have quietly played much better baseball of late and have crept their way up the standings both in the Wild Card and AL Central races. While it's doubtful they catch the Detroit Tigers, who are their opponent this weekend, Kansas City can make things interesting for the three teams currently holding Wild Card spots in the American League: New York, Boston and Seattle. The Tigers took the series opener 7-5 on Friday and will look to secure a series win on Saturday. Michael Wacha (8-9, 3.34 ERA) starts for K.C., while the Tigers turn to Chris Paddack (4-11, 5.10 ERA). Wacha has allowed two earned runs or fewer in each of his last seven starts for the Royals, while Paddack, who was traded by Minnesota at the deadline, is coming off an eight-run blowup outing against his former team. The SportsLine Projection Model, which simulates every MLB game 10,000 times, likes the Tigers on the money line as Detroit wins in 65% of simulations, returning value at -125 odds.

The WNBA returns with a three-game slate on Saturday, with the Liberty visiting the Dream at 2 p.m. ET, the Aces at the Mystics at 3 p.m. ET and the Sun at the Sky at 4 p.m. ET. In the New York vs. Atlanta matchup, WNBA expert Max Meyer is targeting Sabrina Ionescu's total points prop line of 17.5 as part of his WNBA best bets for Saturday.
