The 1977 Los Angeles Dodgers season had Tommy Lasorda replace longtime manager Walter Alston as Manager of the team. The Dodgers won the National League West by 10 games and defeated the Philadelphia Phillies in four games in the NLCS, then lost to the New York Yankees in the World Series.
The New York Yankees beat the Phillies in the 1977 world series. 
It doesn't say that the Yankees directly played the Phillies in the world series that year, but it does say that the Yankees were the overall winners.  So they may have won the title, but we aren't sure if they played and beat the Phillies.
