Here's a detailed account of the harmonica incident
Although Phil Linz could have been blamed for the firing of Yogi Berra from the Yankees in 1964, Linz is attending a ceremony to honor his teammate that's now part of the Hall of Fame. He even plans to take with him the device that lead to the infamous argument they had. This device is the harmonica.
In this annual fundraising dinner of the B.A.T, who's expected to gather a hundred of past and present players to celebrate Yogi Berra's career, maybe enough years had passed so Berra wouldn't mind if he could hear a few tunes. Linz joked they'll find out later and that he knows he can play "Mary had a little lamb." It was the exact song that angered Berra and caused his violent outburst that was so bad it reached national news and had since been dubbed as the harmonica incident. It happened one afternoon in August 20, 1964. The Yankees just lost with a score of 5-0 versus the White Sox, dropping them from first place by 4 ½ games. Since their bus was late to depart for O'Hare Airport, Linz took out his new harmonica. He read the manual and started playing. Yogi Berra, who was the team manager at that time, shouted at Linz to stop playing. Linz didn't clearly understood what he said so he asked his teammate Mickey Mantle what the coach said and Mantle told him Berra wanted Linz to play louder.
Berra then charged toward him. He threw the harmonica to Berra and Berra threw it again but it hit another player in the knee. The next day, the harmonica incident was all over the news since some reporters were with them at the time it happened. They settled the mishap, with Linz apologizing at Berra for yelling at him. The harmonica incident became so famous that fans threw harmonicas in the field when they had a game and Linz even scored an endorsement deal worth $10,000 from a harmonica company. However, when they lost to St. Louis in the World Series, Berra was fired and the incident between him and Linz was considered as part of the reason why. Despite of this, Linz said Berra never held a grudge against him. He complimented Berra, saying that he was a wonderful human being.
At 73 years old, Linz is currently the account manager for New York insurance company. He is a fan of the Ravens by way of his upbringing.
