The Mariners held their own in a pitching battle with the Yankees, as new signing Luis Castillo marked his first home start by giving up just three hits through eight scoreless innings.
Seattle's relief pitching was similarly effective, while there were a series of stunning defensive plays as the two teams repeatedly failed to bat in runners in scoring positions.
Eventually, after more than four hours of play, a pinch-hit single from Luis Torrens scored Eugenio Suarez to the delight of a raucous Seattle crowd.
"Baseball's not a boring game," Mariners manager Servais said after the 1-0 victory.
"I've been at a lot of major league games, I've been in a lot of major league games, and that was one of the best games I've ever seen.
"The electricity in our ballpark tonight, the fans were incredible. As we sit here in early August, we've got big things ahead of us."
The Mariners occupy the second AL wild card place at 60-52 as they bid to end a 21-year playoff drought.
"I don't know, because we haven't been to the postseason in a while, but I'm assuming it would be like this and maybe a little bit better," Servais added.
"Our fan base is starved for this type of baseball. We have a team that can provide it. We're fun to watch. We can be frustrating to watch.
"I get all that as a fan and what it means to hang on the edge of your seat for every pitch. That's what baseball is about, and our team embodies that."
