BetMGM Bonus Code TOPACTION
The BetMGM bonus code TOPACTION unlocks a First Bet Offer worth up to $1,500 in bonus bets, one of the biggest safety nets among all the MLB betting promos for Skubal's debut. Register, make a qualifying deposit, and place your first wager: win it and the cash is yours; lose it and BetMGM returns your stake in bonus bets, up to $1,500. Because the full amount backs a single opening bet, this is the offer for bettors who want to swing harder on a Dodgers run line, a Cubs upset at Wrigley, or a Skubal strikeout total.
If your first bet loses and the refund tops $50, it arrives as five equal bonus bets rather than one lump credit; refunds of $50 or less come as a single bonus bet. Either way, you get multiple cracks at turning the insurance into real winnings across the MLB slate.

Updated 2026 World Series Odds Today
The Skubal blockbuster didn't just change the Dodgers' rotation, as it moved the entire World Series board. Los Angeles was already the clear favorite, but landing a two-time Cy Young winner tightened its price even further.

Here's a snapshot of the latest 2026 World Series odds, via DraftKings Sportsbook (odds updated Aug. 4 and subject to movement):
| Team | World Series Odds |
|---|---|
| Los Angeles Dodgers | +150 |
| New York Yankees | +600 |
