"The Arizona Diamondbacks and their new general manager, Kevin Towers, have made 23-year-old outfielder Justin Upton available and among the teams interested are the Seattle Mariners.

Upton, who wields the kind of bat the Mariners don't have, has a road-block in place that undermines Seattle's chances - a no-trade clause in his contract that, according to FOXsports.com wiz Ken Rosenthal, includes the Mariners.

Does that make a deal impossible? No, just highly unlikely.

Not only would the Mariners have to overwhelm the Diamondbacks with an offer - one almost certainly including Michael Pineda and Dustin Ackley - they would have to persuade Upton to then accept a trade. That would likely mean money, and lots of it."
