Autographs of Buck Martinez

John Albert "Buck" Martinez (born November 7, 1948) is an American former professional baseball catcher and manager, and was the television color commentator for the Toronto Blue Jays until his retirement in 2026. He played 17 seasons in Major League Baseball (MLB) with the Kansas City Royals, the Milwaukee Brewers, and the Toronto Blue Jays. Since the end of his playing career, he has been a broadcaster, working on the Blue Jays and Baltimore Orioles radio and television broadcasts, and nationally for TBS and MLB Network. Martinez managed the Toronto Blue Jays from 2001 to May 2002 and Team USA at the inaugural World Baseball Classic in 2006.
Martinez attended Elk Grove High School, Sacramento City College, Sacramento State University, and Southwest Missouri State University. He was originally signed by the Philadelphia Phillies as an amateur free agent before being taken by the Houston Astros in the 1968 Rule 5 draft. On December 16, 1968, the Astros traded Martinez to the Kansas City Royals alongside Mike Sinnerud and Tommy Smith in exchange for Johnny Jones.
Martinez made his major league debut on June 18, 1969, against the Oakland Athletics. He pinch-hit for Ellie Rodríguez in the ninth inning, and hit a flyout for the game's final out. He played in 72 games with the Royals that season, batting .229 with four home runs and 23 RBI. He is mentioned in Jim Bouton's 1970 bestseller Ball Four as John Martinez, a player Bouton and his Seattle teammates know little about. During a meeting, as Bouton's team is devising strategies to effectively pitch to their opponents, manager Joe Schultz lacks any concrete suggestions about the rookie Martinez, and famously advises that they just "zitz" him.
