A bit more complicated. But yeah, Wood was part of the trade. It would have actually been a real good trade for the Marlins. And for us. Instead, Marlins got nothing.

But, if I remember correctly, Mathis was also going to be included. But as you said, the hangup was on Wood. Marlins wanted both Wood and Kendrick, and the Angels would only include one of them.
