Maybe a thank-you note would have sufficed.

Torii Hunter's gift of expensive champagne to the Kansas City Royals has the Minnesota Twins outfielder in some bubble trouble.

Hunter's gift of four bottles of Dom Perignon, which he had delivered to the Royals clubhouse this past weekend, was meant as a reward for the Royals sweeping the Detroit Tigers last September, allowing the Twins to come from behind to win the American League Central. The gift fulfilled a promise Hunter made last fall.

But baseball has rules about this sort of thing.

Namely, rule 21-b, which proclaims "Any player or person connected with a Club who shall offer or give any gift or reward to a player or person connected with another Club for services rendered ... in defeating or attempting to defeat a competing Club ... shall be declared ineligible for not less than three years."
