⚾ The Seattle Mariners' teal jerseys are among the most nostalgic and beloved alternate uniforms in the history of Major League Baseball — a color identity that connects the franchise to the 'Refuse to Lose' era and to decades of passionate Seattle baseball, and that continues to be one of the most recognizable uniform variants in the sport. Felix Hernandez, the pitcher from Valencia, Venezuela, who became 'King Felix' across 15 seasons as the face of the Mariners franchise, signed this teal Seattle Mariners baseball jersey, authenticated by James Spence Authentication (JSA).

🌟 Valencia, Venezuela — The King's Arrival in Seattle

Felix Hernandez was born on April 8, 1986, in Valencia, Venezuela, and signed with the Seattle Mariners as an international amateur at age 16 before debuting in the major leagues at 19 — one of the youngest pitchers in franchise history. His combination of a mid-90s fastball, a devastating changeup, and an advanced pitching intelligence made him immediately effective, and by his mid-20s he had established himself not only as the best pitcher in Mariners history but as one of the most complete pitching packages in either league. The nickname 'King Felix' was coined by fans who brought royal banners and yellow-and-green 'K' crowns to Safeco Field whenever he pitched — one of baseball's most beloved in-park fan traditions.

🏆 2010 AL Cy Young Award — The Record That Made History

Felix Hernandez won the 2010 American League Cy Young Award with a record of 13 wins and 12 losses — the first pitcher in modern baseball history to win the award with a losing record, and a milestone that changed the way baseball analysts and voters talked about pitcher valuation. Despite the losing record (a function of run support, not Hernandez's performance), Hernandez posted a 2.27 ERA across 249.2 innings — numbers so dominant that the Cy Young voters correctly recognized him as the best pitcher in the league regardless of how many wins the Mariners provided behind him. The 2010 Cy Young changed how the award is evaluated. Condition: NOS.

⭐ The Perfect Game — August 15, 2012

On August 15, 2012, Felix Hernandez threw the first perfect game in the history of the Seattle Mariners — 27 batters, 27 outs, zero base runners, a final score of 1-0 over the Tampa Bay Rays at Safeco Field. It was the 23rd perfect game in MLB history, and one of the most celebrated individual pitching performances in Mariners history. The 'King's Court' section of Safeco Field erupted with every strikeout in a defining moment for a franchise that had never previously produced a perfect game, and Hernandez's place in Mariners lore was permanently secured in one afternoon.
