You can win a lot of money betting on MLB parlays, but if you get one leg wrong, it doesn’t matter that you got the other seven right. You wager grades as a loss. But if you register for a new account with BetMGM to bet on MLB parlays, you can protect your stake with a $1,500 First Bet token.

A first bet token is a form of bet insurance. If your wager loses, you'll get the stake back in bonus bets. Something like this could really come in handy if you want to bet on an MLB parlay. More on the First Bet in a moment; here’s our top MLB parlay pick for Saturday, Sept. 20.

Featured Bet: MLB Parlay Pick, Saturday, Sept. 20

Dodgers -1.5 at -115 (vs. Giants)

Tyler Glasnow has been unhittable pitching at home (2.38 ERA in ten starts with a .159 OBA). Giants starter Kai-Wei Teng has been at his best on the road (5.85 ERA in five starts with a .263 OBA), but has been great when pitching at night (1.46 ERA in three appearances, two starts with a .173 OBA).

The Dodgers hit .300 over the last week; the Giants have hit .164. It is doubtful they turn things around tonight vs. Glasnow.

Astros ML at -115 (vs. Mariners)

Control of the AL West is on the line. Houston is going with their ace, Framber Valdez, on the mound. Valdez has had a rough September with a 7.88 ERA across three starts, but he has been solid this season at home (6-3 in 14 starts with a 2.21 ERA and .217 OBA). George Kirby has struggled on the road, going 4-4 in ten starts with a 5.74 ERA and .285 OBA.

In two starts and 12 innings vs. Seattle, Valdez has allowed six hits and one earned run. In his one start vs. Houston, Kirby was chased after 3 2/5 innings after giving up six hits and five earned runs.

Guardians ML at +105 (vs. Twins)

Cleveland has been on a roll with eight straight wins, including a 6-2 win Friday night. Minnesota is out of the postseason and playing accordingly, having lost its last three and seven of the last ten. However, Joe Ryan (Twins) has held Cleveland hitters to a .186 BA (18-97).

However, Cleveland has an immense amount of momentum here. At +105, there is value in taking the Guardians to win.

MLB Parlay Odds: +616

A $100 wager will result in a $716 payday, your stake plus $616 in winnings.

Upcoming Schedule—MLB, Saturday, Sept. 20

  • Cleveland Guardians vs. Minnesota Twins @ 2:10 p.m. EST.

  • San Francisco Giants vs. Los Angeles Dodgers @ 9:10 p.m. EST

Who doesn’t like the idea of taking $100 and turning it into $716? Silly question; we all love the idea. However, taking on the risk involved to make it happen does not sound ideal. Were you to risk the maximum allowed under this promo, $1,500, we’re talking about a $10,000+ payday.

But if you were to take that risk after signing up for a new account with BetMGM and claiming your $1,500 First Bet, and lose, you’d get your stake back in the form of five $300 bonus bet tokens. It sounds to me like signing up for an account with BetMGM is a win-win!
