MLB.com's Jim Duquette's trade prediction...
4. J.A. Happ, Blue Jays: The southpaw continues to be consistent from the left side, sporting impressive stats again this year despite pitching for a struggling Toronto team. Given his attack mentality and experience in both leagues, the 35-year-old will likely receive attention from a sizable number of clubs. He looks like a perfect fit to return to the Senior Circuit to join a Brewers squad that needs more rotation depth to complement its dominant bullpen.
Prediction: Happ to Milwaukee for a package of right-hander Corbin Burnes (MLB.com's No. 58 prospect) and outfielder Brett Phillips (Brewers' No. 5 prospect).
9. Josh Donaldson, Blue Jays: Donaldson has suffered a number of calf-related injuries this year, and his most recent setback may hurt his chances of being traded altogether -- which is why he ranks so low on the list. If he stays healthy, however, he could bring back a significant return for the Jays -- something similar to what the Orioles might receive for Machado. Look for him to return from the DL toward the middle of July with the possibility of becoming a top trade target in August if he returns to form. The Cubs could use roster depth and extra punch in their lineup, and manager Joe Maddon is one of the best at rotating his personnel for maximum production.
Prediction: Donaldson to the Cubs for a package of right-handers Adbert Alzolay (team's top prospect) and Alex Lange.
