Rob Neyer, in Rob Neyer's Big Book of Baseball Legends, investigated the claim that Munson once deliberately dropped six or seven of Ron Guidry's strikeout pitches because of his competition with Fisk.
Neyer discovered what really happened from Marty Appel. It is a great story, but it apparently never happened. Still, the following is what Appel says.
Munson was aggravated that Fisk received more attention than he did. "It's that [Curt] Gowdy on NBC," Munson told Appel. "He's from Boston. He can't stop talking about Fisk on national telecasts."
Appel, who was the New York Yankees' PR director, had added some fielding statistics to the daily press notes sometime in June, 1976, which was not usually done. The Sporting News published fielding statistics once a month in those days.
Munson saw that Fisk led catchers in assists with 48. He had 46.
"What the hell is this?" he asked Appel. "This is a [expletive] statistic. How could you print this?"
In the game that night, Munson dropped the third strike and threw to first base when a batter struck out in the first inning. Munson pointed to Appel as if he were saying, "That was for you."
Munson dropped two more third strikes and looked toward Appel after each on. After the game, Appel spoke to the catcher, whose three assists put him ahead of Fisk.
"Did you drop those on purpose because of that press note?"
Munson ignored Appel.
Neyer's research revealed that Munson never dropped three third strikes and turned them into assists in one game. Neyer used Retrosheet as one of his primary sources.
There are two points to the story. The first is that the Munson-Fisk rivalry couldn't have been any more intense. The second is that great stories can become true stories.
