Meanwhile, Seattle’s bullpen, which has allowed just 2.9 runs per game in June [verified], will need to contain Baltimore’s late-game power hitters like Adley Rutschman (17 HR this season).
Pitching Matchup: Mariners’ Rotation vs. Orioles’ Lineup
Seattle’s Cal Stephens (Game 1) (4-2, 3.15 ERA, 1.04 WHIP) will look to build on his strong June performance, where he posted a 1.80 ERA in three starts [verified]. The right-hander will face Baltimore’s lineup, which has struggled against right-handed pitching this season (301 PA, .239 avg) [verified].

Defensive Shifts & Bullpen Strategy
The Mariners’ defensive shifts—ranked third in the MLB in defensive runs saved [verified]—will play a major role against Baltimore’s lineup, which has a .289 average on ground balls [verified]. Seattle’s infielders, led by Josh Bell (shortstop) and Cal Stephens (second base), will look to turn double plays and limit extra-base hits.

The Orioles’ closer, Guillermo Hernández (2.70 ERA in 2024), will look to close out the game against Seattle’s Julio Rodríguez, who has a .321 average against left-handed pitching [verified].
Playoff Implications: AL East Race & Wild Card Push
The Orioles, currently in first place in the AL East, will look to extend their lead over the Yankees (38-38) and Red Sox (37-39) [verified]. A win in Seattle would put Baltimore at 41-36, further solidifying their position at the top of the division. Meanwhile, the Mariners—who are just 2.5 games back of the Wild Card cutoff—will need to capitalize on this series to stay in contention.
According to MLB’s Wild Card standings [verified], the Mariners are currently tied for fourth place in the AL Wild Card race, behind the Rangers (42-34), Red Sox (37-39), and Yankees (38-38).
