Mandatory Credit: Joe Nicholson-Imagn Images | Joe Nicholson-Imagn Images The Mariners drew more fans in April than they have in than 20 years. T-Mobile Park hs hosted 539,263 fans so far in 2026. That’s the second most in March and April in the history of the park, only bested by 619,771 fans in April 2002. The average attendance over 17 games (31,721 fans) is sixth most, behind all the years 2000-2004.

Not that many fans showed up to Opening Day. Well, it was essentially a sell out at 44,938 fans. But that’s actually the fourth fewest in the history of Opening Day at T-Mobile Park (though still a slosh higher than 42,871 on Opening Day last year). Why? Probably because first pitch was at 7:10 p.m. on a Thursday against the Guardians with the temperature in the 40s. The best attendance so far actually came on Saturday, April 18, with 45,552 tickets sold. About 10,000 of those fans went home with a Cal Raleigh 70s Night jersey. The others were treated to 70-degree weather while they watched the Mariners snap a four-game losing streak against the Rangers. I wrote at length about the Mariners attendance at the end of last season. I did some loose math in search of what determines attendance, and found to no surprise that fans mostly like winners. Teams that win see more fans throughout the season, and teams that make the playoffs often get a big boost the following year. I figured there’s a reasonable shot for the Mariners to draw three million fans this year. Attendance is up in April for a reason. In that post, I pointed out that the April schedule looked like a tough draw. For instance, I thought the Guardians weren’t ideal out the gate in the frigid days of March. That ended up being wrong. Yes, Opening Day attendance was (relatively) low, as stated above, but game two was the fourth highest attended game two in the history of the park. Game three was the second best game three. More than 156,000 fans poured into the stadium on Opening Weekend. Fans were excited to see their new banner. I also pointed out the timing of the series was not ideal. This ended up being correct. It was the second series of the season in March on a Monday to Wednesday for the only home series against the Yankees of the year. Fans care very much about who the Mariners play when deciding whether to show up, and the Yankees tend to be one of the five biggest draws in Seattle each year. This year, only an average of 27,832 fans showed up, making it the third lowest attendance for a series against the Yankees in the history of the park. Still, fans showed up big time for the series against the Rangers and Astros. If attendance were to hold at the level from April, the Mariners would expect to draw 2,569,401 fans in 2026, or just a smidge more fans than 2025. If the team wins, however, attendance should trend up as the weather gets warm. This isn’t a bad start toward three million. After the road trip, the Mariners will face the Royals for Randy Johnson Number Retirement Weekend. Fans will get a jersey on Friday, they’ll get to see the Big Unit himself on Saturday, and they’ll get a Kingdome pin on Sunday. Then they’ll face the Braves — another potentially big draw — on that pesky Monday through Wednesday slate. Perhaps warmer weather will compel larger turn out. Later in the month is the Vedder Cup, followed by a weekday series with the . How will the Mariners coax fans to the ballpark to see the South Siders? A well-timed bobblehead, of course. As the summer progresses, there will be jersey days and collegiate nights and value games and fireworks and bobbles and Funkos and Blue Jays. The Mariners will also celebrate their 50th season on August 8 against the — the same team and dates of last year’s spectacular weekend. The Mariners finish the year with a six-game homestand — two against and four against the Angels. Again, if they’re relevant, people will show up for a chance to see the Mariners clinch their first ever back-to-back AL West title.
