Stumbled across a Mettle the Mule reference in 1981 Mets Fog Game article

My Joel Youngblood search turned up this article about the fog game which is interesting enough…but look who gets sort of mentioned…

If the Mets’ pet mule had been roaming the lawn beyond the centerfield fence, he would have been lost in the night.

The umpires, embarrassed by the fact that the home team still had a man on third base with nobody out, rendered a decision that would have pleased Solomon or even Chub Feeney, the president of the National League: play suspended by fog, all the records count (including the fogbound three‐bagger), the game to be replayed in its entirety at a later and presumably clearer date.  (via NY Times)

Despite Mr. Met acting like he’s such a big fan, he was nowhere to be seen in the 1980s (or 1979, I guess the Seaver trade got to him too).  Nowhere.  We had a mule.  Where the hell were you Mr. Met?
