Red Sox. Yankees.
Once upon a time, the rivalry was so heated, Boston's ace pitcher threw New York's 72-year-old bench coach to the ground. Alas, the two teams just don't seem to go at it with the same intensity these days.
That might have changed, at least a bit, with the flip of a bat Tuesday night.
It happened in the top of fifth inning in the Bronx. Yankees' rookie Hector Noesi nearly hit David Ortiz with a pitch - perhaps in retaliation for Mark Teixeira's plunking earlier in the game.
Big Papi brushed off the inside pitch and crushed a two-run homer, flipping his bat with a flourish.
Yankees manager Joe Girardi was not amused by the timber toss, the Boston Globe reports.
"I didn't care for it,'' he said. "I don't know if [Ortiz] was upset that he came in hard on him."
He went on: "I never had a problem with David. David has always played the game hard. I'm just protecting my young kid."
As for David, he laughed off the bat flip in typical Big Papi fashion - referring to himself in the third person.
"That's Papi style," Ortiz smiled. "It's not the first time and it's not my last one. I'm a home run hitter. It's not like I do it all the time. What can I tell you? Just another homer for Papi."
Seems harmless enough. But we'll see if "Papi style" adds any more spice to the rivalry when the teams meet again tonight.
