“Dalkowski was famous for his unpredictable performance and inability to control his pitches. His alcoholism and violent behavior off the field[citation needed] caused him problems during his career and after his retirement. After he retired from baseball, he spent many years as an alcoholic, making a meager living as a manual laborer. He recovered in the 1990s, but his alcoholism left him with dementia[6] and he had difficulty remembering his life after the mid-1960s.”

This is a pretty interesting story. I wonder that if he actually did throw 110 mph the umpires didn’t give him credit for pitches that just nicked the strike zone because they were too fast. Although there’s a good chance, he was way out of the zone.
