On January 22, 1969, the Houston Astros trade Rusty Staub to the Montreal Expos for Donn Clendenon and Jesus Alou. But Clendenon refuses to report to Houston, and eventually announces his retirement. The Astros petition Commissioner Bowie Kuhn to void the deal, but Kuhn later rules that the trade will stand and that Clendenon will remain with the Expos. Kuhn also orders the teams to work out additional compensation.
