In regard to the Medwick incident and Klem's comment :
Crespi returned to the lineup on June 18 versus the Dodgers at Ebbets Field and found himself at the center of a brouhaha. In the bottom of the sixth inning, Brooklyn’s Joe Medwick attempted to advance to second base on a wild pitch. St. Louis catcher Walker Cooper quickly recovered the ball and threw to Marion covering at second. Medwick was 10 feet from the bag when the ball arrived, but he nonetheless slid spikes high into Marion. As Marion and Medwick exchanged words, Crespi took Medwick down with a “flying tackle” as both benches emptied.24 After cooler heads prevailed, Medwick and Crespi were ejected, and each was subsequently fined $25 by National League President Ford Frick.25 Bill Klem, umpiring supervisor of the National League, asked Crespi about the incident the next day. After Crespi admitted he got a couple of good licks in on Medwick, Klem offered his hand and said, “Put ‘er there kid, you’re alright.”
