Before the June 15, 1976 trading deadline, Charlie Finley contacted the New York Yankees and the Boston Red Sox. He had proposed a trade to the Boston Red Sox that would have involved Joe Rudi, Rollie Fingers, Vida Blue, Gene Tenace and Sal Bando for Fred Lynn, Carlton Fisk and prospects. In trade talks with the Yankees, Finley proposed Vida Blue for Thurman Munson along with either Roy White or Elliott Maddox. Finley also offered Joe Rudi for Thurman Munson.
On June 14, 1976, Finley was unable to make any trades. He had started contacting other teams about the possibility of selling his players' contracts. Joe Rudi, Vida Blue, Don Baylor, and Gene Tenace were worth $1 million each, while Sal Bando could be acquired for $500,000. Boston Red Sox General manager Dick O’Connell was in Oakland as the Red Sox would play the Athletics on June 15. Field manager Darrell Johnson had declared that he was interested in Joe Rudi and Rollie Fingers. The Red Sox had agreed to purchase both contracts for one million dollars each.
Dick O’Connell had contacted Detroit Tigers General manager Jim Campbell to purchase Vida Blue for one million dollars so that the New York Yankees could not get him. Gabe Paul of the New York Yankees advised that he would pay $1.5 million for the opportunity to acquire Vida Blue. Finley offered Blue a three-year extension worth $485,000 per season to make the sale more attractive to the Yankees. With the extension, the Yankees agreed to purchase Blue.
Finley had then proceeded to contact Bill Veeck of the Chicago White Sox about purchasing Sal Bando. He then contacted the Texas Rangers, as they were interested in acquiring Don Baylor for the one million dollar asking price. Three days later, Bowie Kuhn voided the transactions in the "best interests of baseball." Amid the turmoil, the A's still finished second in the A.L. West, 2.5 games behind the Royals.
