The White Sox could make a big move at the trade deadline, according to FoxSports.com’s Ken Rosenthal and Jon Paul Morosi.

As both Danny Knobler and Jon Heyman have mentioned, the White Sox are interested in Zack Greinke

The White Sox, however, have a weak farm system, and may not have the pieces needed to acquire him. Because of that, Morosi and Rosenthal suggest the White Sox may need to involve another team in order to get Greinke in a trade.

Gavin Floyd could be involved in a potential deal. The White Sox are “eager” to move him.

The Blue Jays have scouted Floyd recently, and the White Sox have been scouting Justin Nicolino, one of the Jays pitching prospects. 

While Rosenthal and Morosi’s trade proposal is highly speculative, they note that the White Sox and Blue Jays were involved in a three-team trade last season.
