BetMGM Bonus Code ACTION1550 for Cavs vs. Raptors — Game 4 (1 p.m. ET, ESPN)
The Cavs travel to the Raptors for Game 4 of their NBA Playoffs first-round series at 1 p.m. ET on ESPN at Scotiabank Arena.
So far, no team has won on the road, which means this series could extend to six or seven games. The Raptors won Game 3, 126-104, behind a 33-point performance from Scottie Barnes.
Current BetMGM odds for Cavs vs. Raptors Game 4:
- Spread: Cavs -3.5 (-110) | Raptors +3.5 (-110)
- Total: O 221.5 (-105) | U 221.5 (-115)
- Moneyline: Cavs -165 | Raptors +135
Let's say you bet $100 on the Raptors moneyline (+135) with BetMGM bonus code ACTION1550. You either profit cash with a win or if the pick misses, your $100 wager is returned in bonus bets.
