There is, however, plenty of evidence that they lost games. And season ticket-holders: By last account, they were outpaced by the Sounders (though of course the Sounders play a much shorter season, so their season tickets cost less.)
The M's may have sold more season tickets by signing Ken Griffey Jr., though we suspect that nostaglists will instead buy tickets in smaller quantities. And we must remember that playing Griffey in the field--which appears to be the team's intention--will lose games, meaning lower attendance.
Remember when brash young Junior was known for predicting his home runs to teammates in the dugout? We couldn't find the article citing it, but we're sure it happened. Maybe it was to Kevin Mitchell? Either way, take a trip down memory lane. And know that these days, Junior's predicting singles.
