Who THE FUCK Are You? Who who, who who?

So right now there are two sports commercials that have "famous athletes" in them, yet I just don't know who they are.

Commercial One: This is a commercial for the WBC. In it are Jeter, A Rod, Ichiro, and someone else. Are four players talk about former teams they've played on like the names of minor league teams and such. And then at the very end they say "Now I play for America" and Ichiro 'says' "Now I play for Japan. And the repeat." Who is the fourth baseball player, the one who says he will play for Mexico?

Commercial Two: This is a commercial for Sobe drinks and originally aired during the Super Bowl. In it are three football players- two black and one white- and they're just dancing around seemingly pretending to be ballerinas. They are against a white back drop and little CGI lizards are dancing around as well. In the end, one of the football's face turns into a lizard. It was speculated that the players where Ray Lewis, Justin Tuck, and Aarom Kampman, but to be honest, it's not 100% sure to me.

Please tell me who these players are!
