The San Francisco Giants and the Los Angeles Dodgers sometimes don’t get nearly enough publicity as they should for being such a fierce rivalry. Heck, they followed one another from NYC to California to keep things going. They renew their rivalry this weekend, and Buster Posey delivered the first big knockout punch of the year between the two with the game tied at 2, nobody on base, and a 3-2 count: The walk-off HR is so much more exciting than any other ending in sports (with the exception of a Game 7 goal in OT of the Stanley Cup playoffs). It isn’t shocking that Posey was the one to deliver in the tight spot last night. That’s what your leader does. This was a great way to end a game that began in a pretty awesome way as well.
