In 2015, the Red Sox chose to forgo the official criteria and retire Pedro Martínez's number 45. Martínez only spent 7 of his 18 seasons in Boston. In justifying the number's retirement, Red Sox principal owner John Henry stated, "To be elected into the Baseball Hall of Fame upon his first year of eligibility speaks volumes regarding Pedro's outstanding career, and is a testament to the respect and admiration so many in baseball have for him." After announcing Martínez's number retirement, the official criteria no longer appeared on the team website nor future media guides.
