...Johnathan Richard Buck.
There was actually a sort of x-factor in Octavio Dotel, who was sent to Oakland from Houston, but then became a Yankee before becoming a Royal, then a Brave, and finally a White Stocking. Mike Wood's been out of baseball for two years. Beltran of course went to Houston, and has been a Met ever since his partial season as an Astro. This left Buck and Mark Teahen, who, as of today, joins Dotel in the Windy City. As not mentioned in the story, Kansas City acquires Josh Fields and Chris Getz from Chicago.
Last but not least, it will be interesting to see if Johnny B's still on the roster come April, as Miguel Olivo's got a better arm from behind home, and the Royals, as they should be, are fond of Brayan Pena's bat. What, then, did the Beltran trade mean for Kansas City in the long run? Answer, as you are so inclined to do, in the comments.
