MLB Opening Day begins with Pirates vs. Mets on Thursday, March 26, 1:15 p.m. on NBC, and Action Network highlights this as a top MLB Opening Day betting promo from BetMGM for new users.
You can bet $10 and get $150 in bonus bets if your first bet wins. Enter the BetMGM bonus code ACTIONGET during signup, place your $10 bet, and once it wins, BetMGM deposits $150 in bonus bets directly into your account.
Eligible states: Michigan (MI), New Jersey (NJ), Pennsylvania (PA), and West Virginia (WV).
According to Action Network, this offer ranks among the best MLB Opening Day betting promos, giving fans extra value while watching Pirates vs. Mets kick off the season.
Claim $150 Bonus with BetMGM Bonus Code ACTIONGET Today
If you’ve already got a lean on Pirates vs. Mets prediction, the BetMGM bonus code ACTIONGET lines up perfectly with a single-game card. Paul Skenes takes the mound for the Pirates, making your $10 Opening Day bet especially relevant as you navigate new lineups, early pitcher workloads, and unpredictable bullpens.
The catch is simple: the $150 in bonus bets only appears if that first bet wins, so this isn’t a safety-net promo. Think of Pirates vs. Mets as the “unlock” bet. Once it hits, you can roll those bonus bets into other MLB games or any other matchups on the board. This ACTIONGET promo ranks as the MLB Opening Day betting promo for fans looking to add extra value.
Use our odds calculator to see potential payouts and compare the latest MLB odds before placing additional bets.
In addition to ACTIONGET, BetMGM also offers:
- BetMGM bonus code TOPACTION: a $1,500 First Bet Offer for new users.
- BetMGM bonus code TOPTAN1500: a 20% deposit match, up to $1,500 in sports bonus funds.
Pirates vs. Mets Expert Pick for MLB Opening Day
If you’ve already got a lean on the Pirates vs. Mets expert pick, we recommend Carson Benge not to hit a home run (-3000). We use this big favorite because we must win the first bet to unlock $150 in bonus bets through the BetMGM bonus code ACTIONGET, one of the best MLB Opening Day betting promos available.
The $150 bonus bets only appears if that first bet wins. Once BetMGM credits your account, you can use the bonus bets, but the stake isn’t returned — only the winnings are cashable. To manage variance, split the $150 into multiple bets across different games or markets instead of risking it all at once.
Use our parlay calculator to plan how to deploy these bonus bets across multiple MLB games, helping you maximize potential winnings while controlling risk.
