Over time, Vernon became one of the best-liked ballplayers, mainly through his unique personality and charismatic, but quiet, style. On September 1, 1960, after a season spent as the Pittsburgh Pirates' first-base coach, Vernon was placed on the active list when MLB rosters expanded to 40 men. He appeared in nine regular-season games as a pinch hitter for Pittsburgh, notching an RBI single and an intentional walk in his nine plate appearances to become one of only 29 players in baseball history to have appeared in a major league game in four decades. By his final game played, on September 27, 1960, he was, at 42, the oldest player in the National League by almost a year, and one of the most popular figures in the game. He appeared in 2,409 MLB games without playing in the postseason, third most in history behind Ernie Banks and Luke Appling. Notably, on September 25, 1960, during Vernon's time on the active list, the Pirates clinched the NL pennant; but he was not on the Pirate playing roster for the 1960 World Series, resuming his full-time coaching duties. He earned a World Series ring when the Bucs triumphed in seven games over the New York Yankees.
