The Arizona Diamondbacks are still looking to trade away one of their outfielders, and industry experts have yet to reach a consensus about which outfielder -- Justin Upton or Jason Kubel -- is the more likely candidate, reports Ken Rosenthal of FOX Sports:

Still can't get consensus on which OFer #DBacks will trade. Some in industry say preference is Kubel. Others still convinced it's Upton.

The D'Backs have been shopping their outfielders for months, and now that they have added Cody Ross on a three-year, $26 million deal, a trade is even more of a sure thing. The question that remains is who the outfielder shopped will be.

Upton, 25, has been a mainstay on the rumor mill seemingly since the beginning of time, while the 30-year-old Kubel's name has been dropped in more recently as the "preferred" trade option.

Upton is younger and has the higher ceiling of the two players, but is owed $28.5 million over the next three years, a rather steep price for a corner outfielder. Kubel, on the other hand, will earn $7.5 million in 2013 and has an equally-priced option for the next season.

Both Kubel and Upton put up solid numbers in 2012, and both have rather severe home/road splits, so the choice of who to trade may come down to what kind of package the D'Backs can get in return for the outfielders.
