The Harmonica Incident took place on a New York Yankees team bus on August 20, 1964, en route to O'Hare International Airport. Infielder Phil Linz, slightly resentful at not being played[1] during a four-game sweep by the Chicago White Sox that was believed at the time to have seriously set back the Yankees' chances at that year's American League pennant, began playing a harmonica in the back of the bus. Manager Yogi Berra, feeling that Linz's behavior was inappropriate given the team's recent poor performance, angrily called on him to stop, whereupon Linz threw the harmonica and loudly complained about being singled out despite not having been at fault for the losses.[2]
Journalists on the bus following the team reported the incident in the next day's newspapers, and it became national news. Although Linz was fined for the incident, he received an endorsement contract from harmonica manufacturer Hohner after the company saw an increase in sales. The contract more than made up for Linz's lost money from the fine. Radio stations in Boston urged fans of the Red Sox, whom the Yankees played immediately afterward, to greet Linz at the plate in Fenway Park with a harmonica and kazoo serenade. At an exhibition game against the crosstown New York Mets, Mets players tossed harmonicas onto the field.
The incident had divergent effects on the team. For the players, it ended well: Berra's authority as their manager was decisively established and they went 30–11 through the end of the season, clinching the pennant that had seemed out of reach. For the team's management, which had been dogged all season by reports that Berra could not control his former teammates, it confirmed that impression, and efforts to find a replacement for Berra (that had reportedly already been underway) succeeded shortly afterwards, with Johnny Keane, who was considered likely to be fired from his position as St. Louis Cardinals' manager after the season concluded, secretly agreeing to become the Yankees' manager. Keane's team had also came back from deep in the standings to win the National League pennant, and then defeated the Yankees in that year's World Series. The day afterwards, Berra was fired and Keane shocked his superiors by resigning instead of accepting a contract extension. Keane took over from Berra a few days later.
Despite its role in catalyzing the team that season, the incident has been seen as the beginning of the end of the Yankees' 15-year postwar dynasty,[3][4] since it also coincided with the announcement that the CBS television network was buying the team. Keane was never able to fully earn the respect of either the aging, injury-plagued stars or the few promising younger players, The 1965 Yankees not only failed to win the pennant, they recorded the team's first losing season in 40 years. When the subsequent season started with even worse results, Keane was fired, although that did not prevent the Yankees from finishing in last place. They did not return to the World Series until 1976, nearly four years after CBS had sold the team to George Steinbrenner.
