Pettitte was the first player of the Core Four to retire, announcing his decision at a news conference at Yankee Stadium on February 4, 2011. He told the organization "not to count on his return" after the Yankees lost the 2010 American League Championship Series to the Texas Rangers, citing his desire to spend more time with his family. After spending the season away from baseball, he served as a guest instructor for the Yankees during 2012 spring training and insisted that he was not considering a comeback. However, he reversed his decision on his final day as instructor and rejoined the organization on March 16, signing a $2.5 million minor league contract. He pitched in both the and seasons for the Yankees before announcing his second retirement on September 20, 2013. Although he was initially not going to reveal his decision, it was at Rivera's insistence that he eventually did. The Yankees held a ceremony for Pettitte five days later on September 25, with fellow Core Four members Jeter and Rivera presenting him with a framed base from his final Yankee Stadium start, signed by all his teammates. He made his final appearance on September 28 against the Houston Astros, the only other team he had pitched for in his career. He pitched a complete game—his first since 2006—and by winning his last start, he finished the season with an 11–11 win–loss record. This preserved his records of never having a losing season throughout his 18-year career and being the only pitcher in major league history to have 15 winning seasons (with a minimum of three starts each) without recording a losing season.
