The stadium is empty, because the owners suck. Yankees were shit in the late 80's early 90's talking about moving the team to Jersey because the Bronx was so horrible the fans wouldn't show up. Stienbrenner gets suspended and old, next thing you know they are winning, filling up the stadium, and building a new one next door.

Look at KC isn't Pittsburgh, where High School football was out drawing the Pirates in the Bonds/Bonilla hey day. KC has a cheap owner that was taking revenue sharing checks from the Yankees and giving executives bonuses, instead of investing in player development. Watch in a couople years when Grienke is nearing free agency, they will trade him for a bag of balls. They may trade him when he gets $15mill in arbitration. Its f'd up, but you MLB isn't going to force a sale of the team. They are more likely to let the guy move the team, so he can ruin another market.

Oh, KC usually draws a ton of fans when the Yankees play there. Everybody loves hating on the Yankees.
