For about a week, it looked like the Pirates and Nationals were destined to make a trade that would send Andrew McCutchen to the Nationals, and according to Jon Heyman, they came close. They had a deal on the table involving Lucas Giolito, Dane Dunning, and a third player for McCutchen. Joel Sherman also reports they thought they were close to a deal on Tuesday night.

Now it appears that McCutchen will be staying in Pittsburgh, and the big decision they will have to make is whether to move him to a corner outfield spot.
