The San Francisco Giants have won exactly three series against the New York Yankees over the past 104 years: the 1921 & 1922 World Serieses, and the interleague matchup hosted at Oracle Park (then AT&T Park) in June 2007. It breaks down to just 25 wins in 64 franchise matchups, from New York to the Bay, and since the turn of the century — when interleague play became a regular feature of the sport — the Giants are 6-15 against the Bronx Bombers.
So, you know, whatever. Thank goodness the Giants got off to such a hot start.
