On December 1, Jayson Stark of ESPN wrote in his winter meetings preview that Upton would be the "human trade rumor" in Nashville.

For the third straight winter meetings, the Diamondbacks will spend the week listening on their intriguing 25-year-old right fielder. And although, as one AL exec put it, they might not be "aggressively shopping him, they've definitely done a good job of letting teams know they will listen."
