Digging out my husband's old Encylopedia Baseball, in 1963, Yost was a third base coach In D.C. when his old Senator's ex-teammate, Mickey Vernon was fired as manager.
After letting it be known he'd only do the job until a permanent manager was hired, the Senators traded Jimmy Piersall to the Mets for arthritic-knee'd slugger Gil Hodges, who was ready to call it a playing career and begin managing.
Yost went with Hodges when he left to return to the Mets as manager in 1968. A year later, they were World Champions!
Later on, Yost became third base coach in Boston, but his one game 9-3 loss to the WHITE Sox is recorded as TYING the shortest managerial stints of all time.
Incidentally, a doofus by the name of TED TURNER (Atlanta) made that same list on 5/11/77 with a 2-1 loss to Pittsburgh before NL President Chub Feeney ordered him out of the dugout and back into the stands with all the other drunks.
Thank you for the most informative post. But this was the sentence that made my day! (Such an appropriate use of the term "doofus") :-)
