⚾ Autographed/Signed Edgar Martinez Seattle Blue Baseball Jersey — JSA COA — Seattle Mariners — Dorado, Puerto Rico — Baseball Hall of Fame 2019 — 'The Double' — The DH Who Changed How We Think About an Award

⚾ The National Baseball Hall of Fame waited too long — that was the consensus from the baseball press, from the analytics community, and from the Seattle Mariners organization when Edgar Martínez was finally inducted in 2019 in his final year of eligibility. The waiting was inexplicable to anyone who had watched him hit for nearly two decades in Seattle, posting numbers that stood among the most consistently excellent offensive careers in the game's history, doing it as a designated hitter, and earning the honor of having the DH award renamed in his memory. This is the Seattle Mariners blue baseball jersey signed by Edgar Martínez, authenticated by James Spence Authentication (JSA) — the signed piece from a Baseball Hall of Famer whose signature on a Mariners jersey carries the weight of a 18-year Seattle career that culminated in one of the most celebrated November moments in the franchise's history.

🌴 Dorado, Puerto Rico — An Island's Baseball Legacy

🌴 Edgar Martínez was born on January 2, 1963, in New York City, but grew up in Dorado, Puerto Rico — a municipality on the island's northern coast, roughly west of San Juan, in a region that has produced some of baseball's most celebrated players as part of Puerto Rico's extraordinary baseball culture. The island has given the major leagues a continuous stream of elite talent, and Martínez's development in Dorado's baseball environment produced a hitter with a swing mechanics understanding, a plate discipline, and a contact skill level that made him one of the most reliable right-handed hitters in the American League for the entirety of his professional career.

🚢 Seattle Mariners — 18 Seasons of Pacific Northwest Excellence

🚢 Edgar Martínez spent his entire 18-season major league career with the Seattle Mariners — a franchise born in 1977 and located in the rainy, coffee-and-mountains city on Puget Sound that adopted Martínez with the fierce loyalty of a fanbase who recognized that the quiet, methodical professionalism of a great hitter who showed up, worked, and produced every season was exactly what their team and their city deserved. From 1987 to 2004, Martínez was the constant in a Mariners lineup that changed around him, the offensive anchor who was there through the Ken Griffey Jr. era, the Randy Johnson era, the Ichiro era, and the years in between.

🏆 'The Double' — The Hit That Saved Baseball in Seattle

🏆 On October 8, 1995, in Game 5 of the ALDS between the Mariners and the New York Yankees at the Kingdome in Seattle, in the bottom of the 11th inning with the Mariners trailing 5-4 and two outs, Edgar Martínez hit a double down the left field line that scored Joey Cora and then Ken Griffey Jr. to win the series. The hit — known simply as 'The Double' to every Mariners fan who was alive to witness it — has been called the moment that saved baseball in Seattle, because the franchise was facing serious relocation pressure that only a playoff run could reverse. Martínez's double reversed it. Condition: NOS.
