The Mariners' quest to improve their offense took a hit when Diamondbacks outfielder Justin Upton rejected a proposed deal recently that would have sent him to Seattle for a multi-player package.
But even after this, Upton appears a short-timer in Arizona.
The deal would have sent three or four players back to Arizona, according to CBSSports.com sources. Included among those players would have been relievers Charlie Furbush and Stephen Pryor, minor-league shortstop Nick Franklin and, likely, one of three minor-league starting pitching prospects: Right-hander Taijuan Walker, lefty James Paxton or lefty Danny Hultzen. The clubs discussed the possibility of a second player accompanying Upton to Seattle in the deal. The identity of that player, believed to be a low level minor leaguer, is not known.
