Early Sunday morning, it was confirmed that the Royals and Brewers had agreed to a Zack Greinke trade that sends a handful of young players Kansas City's way while molding Milwaukee into a strong contender. But while Greinke wound up a Brewer, there was a time at which it looked like he could end up a National instead.
The Royals and Nationals were far along in trade negotiations, and Jon Heyman says that reliever Drew Storen and infielder Danny Espinosa could've been a part of the package. However, Greinke's contract with Kansas City gave him limited no-trade protection, and he invoked his rights in turning down a deal to Washington. That killed any possibility of a trade going down.
And so he's off to the Brewers instead. Greinke also had Milwaukee on his list of teams to which he could block a trade, but he chose to accept this one, as he considers the Brewers a better bet to contend than the Nationals. He's also said to like the city, for whatever that's worth.
The Nationals will now presumably turn their attention to trying to sign free agent Carl Pavano.
