Through the first two games of this three-matchup set, the Atlanta Braves and Seattle Mariners have split their current series. The opener ended in a 5-4 win for the M’s at home, a favorable result for a team in need of some positive momentum in front of its home crowd. Last night, Atlanta bounced back with a low-scoring 3-2 victory to get back in the win column amidst what’s been a hot season overall. Today, they settle the score with game three.

Here’s a betting prediction and pick for Wednesday’s Braves vs. Mariners matchup courtesy of MLB odds and lines on DraftKings Sportsbook.

Braves vs. Mariners prediction, preview

Atlanta Braves

The Braves still hold the best record in baseball at 26-11, rattling off seven wins in their last 10 games. Atlanta averages an MLB-best 5.73 runs per game, producing totals of 11, four and three since Ronald Acuna Jr. departed the lineup due to injury. The Braves maintain the best OPS in baseball at .802, slashing .273/.338/.464. They’ve notably out-hit the Mariners in both games of this series, tallying a total of 15 knocks and four homers. On the year, the Braves have a .191 ISO that ranks second in baseball along with 55 home runs, also second most. They also have an 0.42 BB/K ratio but are third lowest in K% at just 19.8%, an impressive mark given the power bats. Atlanta also has one of the best pitching staffs in the MLB. The Braves come in at third in ERA (3.22) and fourth in WHIP (1.18), also sitting second in LOB% (77.5%). The staff is also 11th in K-BB% (14.1%) and ninth in K% (23.7%), marks which ticked upward over the first two games of this series.

Tonight, Atlanta starts LHP Martin Perez. The 35-year-old veteran has been excellent across six appearances, four of which were starts. He has a 2.22 ERA and 0.99 WHIP, though one can argue he’s overperforming an xERA of 4.47 and xBA of .255. He also has just 19 strikeouts in his 28.1 innings.

Seattle Mariners

The Mariners fell to 17-20 after last night, but as mentioned in yesterday’s write-up, the AL West is far from competitive at the moment. The M’s are now just 5-5 across their last 10 games. With just 4.05 runs per game, the 23rd-ranked OPS at .692 and a slash line of .227/.318/.374, it’s tough to argue that this team is underperforming. Cal Raleigh’s continued struggles at the plate have been a major reason as to why, hitting just .180 with a .633 OPS. He’s still bashed seven homers and the team does have a respectable but uninspiring .147 ISO with 41 homers, tied for eighth most. An 0.43 BB/K ratio is around average, but they do have the fourth-worst K% at 24.5%. The pitchers have been good as well, logging a 3.71 ERA that ranks sixth and the seventh-best WHIP (1.24). A 15.6% K-BB% also sits sixth best in baseball and their LOB% of 74.8% is good for fifth among all teams.

Tonight’s starter is RHP Bryan Woo, who’s been a smidge vulnerable to start the season. The 26-year-old was excellent last year with a sub-3.00 ERA and 0.93 WHIP. While his 1.07 WHIP in 2026 is still great across his seven starts, he has a 4.61 ERA and just 29 strikeouts in 41 innings of work. However, he does have a 98th-percentile grade in BB%.

Braves vs. Mariners pick, best bet

DraftKings Sportsbook lists the Mariners as -141 Moneyline favorites at home tonight. The Braves come in at +117 odds to win outright. The run total also sits at eight combined runs between these sides.

Best Bet: Bryan Woo over 2.5 earned runs allowed (+127)

Woo is in quite the cold stretch, allowing a combined 16 hits and six homers across his last two starts. His inning count from those two appearances? Only 9.0. He’s also struck out just three batters in this span, so clearly, things aren’t going well for him at all after getting shelled in these appearances. With his confidence possibly shaken, I think that Atlanta’s offense should capitalize and jump on him early. Woo is great, but the recent form and the prowess of the Braves’ offense should prove too much for him to handle in the early innings of today’s game. With that in mind, I like over 2.5 earned runs for him in this one.
