The MLB regular season is moving fast, and Wednesday, May 20, 2026, brings a loaded slate of baseball games. If you want to get in on the action, the BetMGM bonus code WSNSPORTS gives new players a great way to start.

Whether you are looking at an afternoon matchup or a night game under the lights, you can use the BetMGM bonus code WSNSPORTS when you set up your new account. This gives you some cushion on your first wager if things do not go your way on the diamond.

Use BetMGM Promo Code WSNSPORTS and Get Up to $1,500 in Bonus Bets

BetMGM has a couple of different welcome options depending on where you live. For most sports bettors across the country, entering the BetMGM bonus code WSNSPORTS unlocks a first-bet offer worth up to $1,500 in bonus bets.

Here is how it works. You sign up, deposit money, and place your very first wager. If that first bet wins, you keep the profits and move on. If that first bet loses, BetMGM will credit your account with bonus bets equal to the amount you lost, up to a maximum of $1,500. It is a straightforward way to get a second chance if your first baseball pick falls flat.

Now, if you live in Michigan, New Jersey, Pennsylvania, or West Virginia, the offer is a bit different. In those states, using the BetMGM bonus code WSNSPORTS gets you a Bet $10, Get $150 in bonus bets offer. For this one, you just need to place a $10 first bet, and you will get $150 in bonus bets added to your account if your first bet wins.

For both offers, any bonus bets you receive cannot be cashed out directly. You must use them to place another bet on the sportsbook. Also, bonus bets expire seven days after they hit your account, so you will want to use them before they disappear.

Best Sports Matchups for Your BetMGM Bonus Code This Wednesday, May 20, 2026

There is plenty of great baseball on the schedule this Wednesday, May 20, 2026. From early matinees to late-night West Coast games, you have options all day long. Below are the current BetMGM odds for some of the biggest games on the schedule.

Please note that odds are subject to change.

Cincinnati Reds at Philadelphia Phillies (1:05 PM ET)

The day starts early in Philadelphia. The Phillies are looking tough at home, but the Reds have a scrappy lineup that can cause trouble if a pitcher leaves the ball over the plate. This is a classic afternoon game where a hot start from either offense could dictate the pace.

Baltimore Orioles at Tampa Bay Rays (1:10 PM ET)

This is a huge battle in the AL East. The Orioles bring a ton of young power to the plate, while the Rays rely heavily on their pitching depth and smart defense at Tropicana Field. The odds are tight for this one, making it a great choice to test out your BetMGM bonus code WSNSPORTS.

Houston Astros at Minnesota Twins (1:40 PM ET)

The Twins are the slight favorites playing in front of their home crowd at Target Field, but you can never count out the veteran bats in the Astros lineup. Houston always plays tough on the road, so expect a close contest that could come down to the bullpens in the late innings.

Place Your Bet on Astros vs. Twins

Texas Rangers at Colorado Rockies (3:10 PM ET)

Whenever teams visit Coors Field in Denver, you have to look out for high scores. The ball flies out of that stadium, and both the Rangers and Rockies have hitters who can take advantage of the thin air. The high over/under total tells you exactly what kind of game the sportsbooks are expecting.

Place Your Bet on Rangers vs. Rockies

San Francisco Giants at Arizona Diamondbacks (3:40 PM ET)

An afternoon NL West rivalry finishes up the main slate of early games. The Diamondbacks are playing on their home turf and hold the edge in the odds, but the Giants are always built to fight through division games. A single clutch hit late in the game could easily decide this one.
