Edgar Martinez is the greatest free agent signing in Mariner franchise history, period.
Some may call this a sympathy pick for his recently failed attempt of get into the Hall of Fame.
Some may call this the wrong pick.
But when your peers label you as one of the best designated hitters of all time, you've obviously done something right.
Signed as a free agent in 1982, Edgar made his big league debut for the Mariners in 1987 as a pinch runner for third basemen Jim Presley. Edgar would play some third base over his career, but by 1995 he was all but strictly a designated hitter.
Edgar's first full few seasons were a success, but he truly burst on to the scene in 1992, when he hit .343, winning the first of his two batting titles and finishing 12th in the AL MVP vote.
Over his career, Edgar batted over .300 10 times while finishing with 2,247 hits and a career .312 batting average. Martinez also hit for power, finishing with 309 homers as well.
In 1995, Edgar Martinez helped lead the Mariners back from an 0-2 hole in the opening round of the AL playoffs against the New York Yankees to an improbable 3-2 come-from-behind series win, capped by Edgar Martinez' walk-off double in Game 5. It is the single most memorable moment in Mariners' history and is commonly known by fans as The Double.
In that series, Edgar hit a whopping .571 and reached base 18 times in five games.
Edgar Martinez may never get the votes to reach Cooperstown, but to many he is one of the main reasons Seattle still has the Mariners.
And with that distinction comes the title of the greatest Seattle Mariner free agent signing of all time.
