Getty Images supplied most of the clues necessary for sleuthing this photo, so I present them and then will have some further explanation of what you’re seeing above.
Glenn Beckert of the Cubs makes head first dive back to 2nd base just in time as Cincinnati Reds 2nd baseman Pete Rose attempts tag in 1st inning of game in Wrigley Field here 4/22. Throw was from Reds’ catcher Don Pavletich. Umpire is Chris Pelekoudas.
With a date that made things fairly easy. This game happened Thursday, April 22, 1965. Beckert, inserted in the leadoff spot in the lineup that afternoon, singled and stole second.
