Who has the most World Series rings in MLB?

Yogi Berra holds the record for the most World Series rings in MLB history with 10 championships, all won as a player with the New York Yankees between 1946 and 1963. He appeared in 14 World Series total, which is also a record. If you include rings earned as both a player and coach, some individuals have additional rings, but Berra's 10 as a player stands as the benchmark. The Yankees dynasty of the late 1940s through the late 1950s was central to his remarkable collection.
