Bidge and Baggy become just the fourth tandem in Cooperstown to play for at least 15 years together on the same club. If you want to take a guess at the others they played for Pirates, Giant (NY) and Yanks.
I'm guessing Whitey Ford and Mickey Mantle are the Yankee combo.
Stargell and Clemente?
That was not the tandem but one of the above is part of the answer.
I would have said Mays and McCovey but I think McCovey was just a SF giant and not an NY giant.
The Giants were Mel Ott and Carl Hubbell.
