Just thinking about this, Tom Seaver and Johnny Bench just might be the greatest battery to ever perform.

Trying to come up with others:

Mickey Cochrane-Lefty Grove on the 1930 A's

Warren Spahn and Yogi Berra on the 1965 Mets actually does not count, Yogi played in only 4 games, only one of which Spahn pitched and Yogi appeared as a pinch hitter, check that out at ultimatemets.com

Ivan Rodriguez did catch Nolan Ryan early in Rodriguez's career (though considering Pudge was a juicier should he still be that highly regarded)

Mike Piazza-Pedro Martinez does count on last years Mets (more smoke involved with Pudge than with Piazza)

Heh, Carlton Fisk caught Seaver as a White Sox, as well as Steve Carlton guess they qualify

Berra-Ford for sheer World Series dominance

Hmmm, any more...
