On Sunday, Conner Menez and Zach Green became the 19,588 and 19.589 players in MLB history. To put that in perspective, those fans lucky enough to be in attendance at the game could have looked around Oracle Park and, at a glance, seen more human beings — nearly twice as many in fact — as have ever taken a field of play for a major league game. From the long, illustrious newly enshrined HOF careers like Mariano Rivera and Lee Smith, to the Gary Browns and Moonlight Grahams of the sport, over 150 years of major league history, less than 20,000 people have ever done what Conner and Zach did this weekend.
