The Atlanta Braves welcome the Seattle Mariners to Truist Park on Saturday night in a matchup that could define both teams' late-season trajectories, with Atlanta (+102) looking to play spoiler against a Mariners squad (-122) still fighting for playoff positioning.
Despite sitting 14 games under .500 at 63-77, the Braves have shown resilience at home and will send promising rookie Hurston Waldrep (4-1, 3.63 ERA) to the mound against Seattle's reliable Bryce Miller (3.91 ERA).
The betting market gives Seattle the edge as road favourites, but Atlanta's superior fielding (.990 percentage, 2nd in MLB) and home-field advantage make this Saturday night showdown far from a foregone conclusion.

Atlanta Braves vs. Seattle Mariners preview
The Mariners arrive at Truist Park riding a solid 73-67 record and clinging to wild card hopes, while the struggling Braves sit at 63-77 and looking to play spoiler down the stretch.
Seattle's offense has been steady but unspectacular, averaging 4.6 runs per game behind 200 home runs, though their pitching staff has kept them competitive with a respectable 4.04 ERA.
Bryce Miller takes the ball for Seattle with strong career numbers, posting a 3.91 ERA and solid strike-to-walk ratio that should give the Mariners a chance against an Atlanta lineup that's struck out over 1,200 times this season.
The Braves counter with rookie Hurston Waldrep, who's shown promise in limited action with a 3.63 ERA across 42 innings, though his inexperience could be tested by a Seattle team that's been scrappy all year.
Atlanta's defense has been excellent, ranking second in the majors with a .990 fielding percentage, but their offense has struggled to generate consistent run production at just 4.41 per game.
With the Mariners desperately needing every win to stay in playoff contention and the Braves playing with house money, this Saturday night matchup could produce the kind of competitive baseball that makes September special.
