Rooting for the Big Maple: The 2025 Mariners Maple Grove T-Shirt Giveaway is a Grand Slam for Fans
Front and center on the crisp white tee, the bold navy lettering proclaims “The Maple Grove” across the chest, wrapped in leafy maple branches that frame the words with both softness and strength. Nestled among the foliage is an illustrated headshot of none other than James “Big Maple” Paxton, beaming in his Mariners cap, ready to mow down hitters with that signature lefty fire. Below the artwork, smaller text proudly reads: “James ‘Big Maple’ Paxton / Seattle Mariners #65”.

It’s the story behind the Grove. In 2017, a dedicated group of Mariners fans dubbed a cheering section “The Maple Grove” to honor Paxton’s Canadian roots and his dominance on the mound.
Whether you cheered for Paxton’s no-hitter in Toronto, proudly wave a leaf for every strikeout, or just love a good sports pun, the 2025 Mariners Maple Grove T-shirt Giveaway is your perfect game day uniform. Don’t leaf this opportunity behind. Show up early, grab your shirt, and let the world know you stand tall in the Grove.
