The Seattle Mariners will retire Edgar Martinez's No. 11 during a ceremony on Aug. 12 at Safeco Field.
The Mariners are scheduled to face the Los Angeles Angels that night.
"This is an incredible honor for me and my family," Martinez said at a news conference where his framed jersey was unveiled. "It's a gift we'll cherish forever."
Martinez, who is scheduled to begin his second full season as hitting coach on manager Scott Servais' staff when the club opens Spring Training in three weeks, was inducted into the Mariners Hall of Fame on June 2, 2007.
