Seattle Mariners’ 2025 MLB Postseason Schedule: Dates, Ticket Options for Cal Raleigh’s Historic Home Run Chase

The Seattle Mariners have made history by clinching their first AL West title in 24 years, securing a prized first-round bye in the 2025 MLB postseason. Cal Raleigh’s electrifying 60-home run season has sparked unprecedented demand for playoff tickets as fans scramble to witness his historic chase.

With their dominant performance culminating in a sweep of the Rockies, the Mariners enter October as legitimate World Series contenders. The team’s ALDS journey begins October 7 at T-Mobile Park, where Raleigh aims to continue his record-breaking power display against baseball’s elite pitchers.

Seattle Mariners’ 2025 MLB Postseason Schedule: Key Dates and Matchups

The Seattle Mariners have secured a prized first-round bye in the 2025 MLB postseason after clinching the AL West title with an 89-69 record. Their playoff journey will begin on October 7 in the AL Division Series at T-Mobile Park, where they’ll face the winner of the Yankees-Twins Wild Card matchup. The complete schedule includes:

• ALDS Games 1-2: October 7-8 at T-Mobile Park (if necessary)
• ALDS Games 3-4: October 10-11 at opponent’s ballpark
• Potential ALCS: Begins October 13 for Mariners if they advance

This marks Seattle’s first postseason appearance since 2022 and only their fifth in franchise history. The team’s .563 winning percentage might not dazzle historically, but their 28 comeback victories – most in MLB – showcase their late-game resilience.

Interesting scheduling quirk – the Mariners will have 6 days off between their regular season finale and ALDS Game 1. That’s enough time to reset the rotation but risks cooling baseball’s hottest September team (22-7 in final month).

Why the Schedule Favors Seattle

The Mariners’ pitching staff benefits tremendously from the extended break. Luis Castillo, who threw 208 innings during the season, will start Game 1 on full rest despite pitching the regular season finale. Manager Scott Servais can deploy his bullpen aggressively knowing they’ll have multiple off-days between series.

Ticket Availability for Cal Raleigh’s Historic Postseason Chase

All standard tickets for potential Mariners home playoff games sold out within 47 minutes of their division clincher. The team announced they’ll release limited standing-room-only tickets 48 hours before each potential game, with prices starting at $175. Secondary market trends show:

The ticket frenzy stems from Cal Raleigh’s 60-homer season and Seattle’s Cinderella storyline. Local businesses report hotel bookings near T-Mobile Park have tripled compared to last September, with many fans planning to attend regardless of ticket availability.

Pro tip for budget-conscious fans: Consider buying for potential Games 3-5 during the Wild Card round. If Seattle sweeps, you’ll get refunded – if the series extends, you’ve locked in prices before the inevitable surge.

Alternative Viewing Experiences

For fans unable to secure tickets, the Mariners will host watch parties at Lumen Field’s Event Center with capacity for 5,000 fans. The team is collaborating with 35 local bars to create “Mariners Postseason Alley” along 1st Ave South, featuring giant screens and food specials.

Cal Raleigh’s Historic Home Run Chase: Playoff Edition

Cal Raleigh’s 60 regular season home runs already place him in elite company – only 10 players in MLB history have reached that milestone. His pursuit of Barry Bonds’ record 73 homers now moves to the postseason, where the difficulty multiplies exponentially:

• Postseason pitchers have lower ERAs (3.80) than regular season (4.22)
• Raleigh will face only elite rotations, with starters averaging 95+ mph fastballs
• Teams will employ extensive defensive shifts and intentional walks in key situations

Historical comps suggest Raleigh would need an unprecedented power surge to challenge the record. When Sammy Sosa hit 66 homers in 1998, he managed just 3 in 7 postseason games. The clean home run record (61 by Roger Maris) remains within reach if Raleigh slugs 2 postseason homers.

Here’s what’s not being discussed enough – Raleigh’s 21% strikeout rate is the lowest among 50-homer sluggers since 2010. That plate discipline gives him a fighting chance against elite October pitching.

Projected Home Run Timeline

Mariners’ Playoff Rotation and Bullpen Strategy

Seattle’s pitching staff enters October with the AL’s third-lowest ERA (3.82) and MLB’s best September performance (2.98 ERA). Their planned rotation:

1. Luis Castillo (Game 1: 2.42 ERA in 8 postseason starts)
2. Logan Gilbert (1.89 ERA in final 6 regular season starts)
3. Bryan Woo (0.87 WHIP vs. AL East teams)

The bullpen features three relievers with sub-2.00 ERAs since August: Andrés Muñoz, Matt Brash, and Justin Topa. Servais plans to deploy Muñoz for multi-inning saves, citing his dominant split-finger fastball that’s held hitters to a .148 average.

Watch for sneaky bullpen weapon Isaiah Campbell – his 96 mph sinker has generated 53% ground balls. Perfect for double plays when Castillo or Gilbert leave runners on base.

Defensive Alignment Changes

Expect Seattle to start Dylan Moore in left field during NL park games, replacing Teoscar Hernández for defensive upgrades. Shortstop J.P. Crawford’s +12 Defensive Runs Saved will be crucial against elite baserunners like Bobby Witt Jr. (ALCS potential matchup).

Historical Context: Comparing 2001 and 2025 Mariners

While the 2001 Mariners set the AL record with 116 wins, this 2025 squad shares uncanny parallels beyond both ending division title droughts:

Don’t overlook intangible factors – this team’s 11-3 record in extra innings shows clutch performance the 2001 team lacked (5-5). That’s the difference between an ALCS exit and potential World Series berth.

Farm System Impact

Unlike the veteran-heavy 2001 roster, the 2025 Mariners feature six homegrown starters including Julio Rodríguez (age 24) and George Kirby (26). This sustainable model suggests Seattle’s window could remain open longer than their 2001-2003 run.
