Let’s analyze BetMGM Sportsbook’s lines around the Braves vs. Mariners odds and make our expert MLB picks and predictions for the best bets.

Season series: Mariners lead 1-0

Seattle picked up a 2-1 series opener win behind a walk-off 2-run HR from C Mitch Garver and an impressive start fromRHP Bryce Miller, who allowed just 1 earned run in 7 inningsin a game which easily cashed the Under (7).

The Braves tied a season low with the 1 run scored, as they also lost 5-1 in Miami against the Marlins April 13. The Under has cashed in 7 straight games for Atlanta. The Braves are on an 11-2 run to the Under in their past 13 games overall and a 4-0 run in their last 4 on the road.

The Mariners have won 4 of the past 5 games, and they’re also on an impressive Under run, as the total has gone low in 6 straight, 11 of the past 12, and 17 of the previous 19 contests. The Under is also 11-2 in the past 13 interleague games for Seattle.

Braves at Mariners picks and predictions


Braves 5, Mariners 2


The BRAVES (-125) are a solid play to bounce back after Monday’s series opener loss.

Atlanta has been getting tremendous pitching from Lopez, who has fired out of the chute by posting All-Star caliber numbers in the first month of the season. On the flip side, Seattle hasn’t been getting the same kind of production from Castillo. Lately, the Mariners (+105) have seen the right-hander turn it around, but he has struggled mightily at home.

Run line/Against the spread

If you’re a little more adventurous, back the BRAVES -1.5 (+145) on the run line rather than playing the moneyline. Don’t do both.

It’s a little more risky, as Atlanta has won 3 of the past 5 games but only covered the run line in 1 of those 3 outings as the favorite, and the Braves are 0-2 in the past 2 tries on the road as run-line favorites. In addition, as well as Lopez has pitched, the Braves are 0-3 in his 3 starts on the run line when favored.


TOTAL 7 (O: -105 | U: -115) should be an AVOID play, as I expect the total number of runs to come right down on the number. If there was a lean, it would be low, based on Lopez’s solid production, but Castillo has been awful at home, too. The best bet is to take a PASS.
