Per Ken Rosenthal:
Article LinkThe Rockies have agreed to trade outfielder Preston Wilson to the Nationals for righthanded pitcher Zach Day and Class AAA outfielder J.J. Davis, the Sporting News has learned.
Before the deal can be completed, the two clubs must agree on how much the Nationals will pay on what remains of Wilson's $12.5 million salary. Also, Wilson must OK the deal because the Nationals are one of five teams to which he can reject a trade.
