An hour away from the A’s christening the domestic portion of their schedule, and just go give you an idea as to what the mood is like in the hours leading up to such a high-adrenaline game, consider:

— Huston Street and Andrew Brown were quietly playing a game of chess, striking the same pose they’ll likely have for the next 159 games.

— Travis Buck was pulling on his socks, chatting amiably with me. He’s on the cover of the team’s Opening Day program. Just three years ago, he was still doing the college thing at Arizona State. “Pretty crazy, huh?” he said.

— Daric Barton was desperately in search of some tickets. “Five of them,” he said. “Family members, and then one for my agent.” Sigh. Shame that last part ever became a part of the American lexicon.

— Reliever Henry Rodriguez, the Rule 5 pick, sat by himself at his locker. In the 45 minutes or so that I was in the clubhouse, I’m not sure he exchanged a word with anybody.

So you see, Opening Day (or Re-Opening Day) might be full of pomp and circumstance. But for most of the players, in many ways, it really is just another day.

With both the A’s and Giants celebrating their respective anniversaries in the Bay Area this season, the time is right to ask which of the two teams has had the biggest impact on your life?

A’s or Giants? Which is the team you just couldn’t live without? If you’ve got a minute, cast your vote and let us know what you think.
