Stanton, Price affect Upton trade market 

January, 16, 2013

The four-prospect offer that the Seattle Mariners made for Justin Upton, built around pitcher Taijuan Walker, was thought by rival executives to be an extraordinary overture. Now that Upton has exercised his no-trade clause and Arizona looks to find another deal with another club, the Diamondbacks' challenge will be to find a similar deal -- at a time when looming trade possibilities may distract potential suitors.

There is an expectation that sometime in the next 11 months, two of the sport's great young stars will be available on the trade market. David Price has three seasons remaining before he reaches free agency, and rival officials believe that the Tampa Bay Rays will trade him in the forthcoming summer or next winter to get the maximum return. And the Miami Marlins have already sent signals that they are open to offers for Giancarlo Stanton, who has 93 home runs in his first 373 games in the big leagues and is only 23 years old.
