The Panama City News-Herald of Feb. 28, 1968 has the following:
"The Mets also completed a minor deal made earlier this week that sent catcher John Sullivan to Philadelphia's San Diego farm club. New York's Jacksonville farm optioned outfielder Johnny Lewis to San Diego in return for outfielder Bill Sorrell."
So we can now correct this for all three players:
February 19, 1968 The New York Mets traded John Sullivan and a player to be named later to the Philadelphia Phillies for a player to be named later. February 27, 1968 The New York Mets sent Johnny Lewis to the Philadelphia Phillies for Billy Sorrell to complete the trade.
