Bruce Markusen, The Hardball Times, March 17, 2020:
With the score remaining tied heading to the ninth, [Cardinals relief pitcher Al] Hrabosky decided to make the Cubs wait by going through his trademark routine, which he called "The Psych." Hrabosky walked behind the mound, furiously rubbed up the ball, muttered a few words to himself as motivation, and then slammed the ball from his bare hand into his glove before stomping back onto the mound.
