Justin Upton rumors: Diamondbacks outfielder reportedly on trading block again

With a little more than a month remaining in the offseason, the Arizona Diamondbacks could be considering a deal involving Justin Upton.

The talented outfielder has been the talk of trade rumors over the past few years, and after a quiet month of December, it appears general manager Kevin Towers is contemplating another move. ESPN's Buster Olney tweeted on Thursday afternoon that the club now has different demands for Upton. Earlier in the offseason, Arizona wanted a shortstop (and possibly more) to part with their 25-year-old outfielder.

It is unclear what Towers is looking for now, although the D-backs could benefit from an influx of hitting talent into their farm system. Olney also tweeted that rival executives feel that Upton, and not Jason Kubel, was the more likely player to be dealt this winter. Kubel has also been on the trade block in recent weeks and could be an enticing piece for an American League team looking to add a DH.

Look for the hot stove to heat up in the coming weeks as front offices reopen following the holiday break.
