Willie Mays turns 90 on May 6 (Thursday). His biographer has a marvelous essay in the Times. He was particularly close to Seaver, who as a college player noticed that Mays didn't button the top of his jersey, so Seaver never buttoned the top of his. They became teammates when Mays was traded to the Mets in 1972, and before each game Seaver started, Mays asked him how he was going to pitch each hitter. As the game progressed, Seaver discreetly signaled to Mays in center what adjustments he was making on the mound, and Mays repositioned himself accordingly. https://www.nytimes.com/2021/05/05/sports/baseball/willie-mays-90.htmlhttps://www.nytimes.com/2021/05/05/sports/baseball/willie-mays-90.html
