Justin Upton trade rejection: Mariners offered 4

There have been rumors all offseason about the Mariners trying to improve their offense. There have been rumors that the Diamondbacks were looking to deal an outfielder. The two clubs found a match and swapped Justin Upton for a package that included Charlie Furbush, Stephen Pryor, Nick Franklin and one of Taijuan Walker, James Paxton or Danny Hultzen, according to Scott Miller of CBS.

There was one problem. Justin Upton has a no-trade clause in his contract that lets him reject a deal to four teams. Jon Heyman reported that the Mariners are on the list along with the Blue Jays, Cubs and Red Sox.

So it is back to the drawing board for the Mariners, who also struck out on Josh Hamilton earlier in the offseason. They have acquired Kendrys Morales and Raul Ibanez, but are still searching for one more bat and apparently aren't afraid to deal from their wealthy minor league system to acquire one.

Arizona is now back to having a surplus of outfielders in Upton, Jason Kubel, Adam Eaton, Gerardo Parra and Cody Ross. As Miller notes in his article, an industry source says that "something is going to happen somewhere with them. I just don't know where or when".

The Diamondbacks are rumored to be shopping Upton and Jason Kubel. Upton has been linked to both the Atlanta Braves and Texas Rangers this offseason.
