One prospect each MLB team should call up
Chicago White Sox: Reynaldo Lopez
There are a few options the White Sox should consider calling up at some point this season. The front office absolutely hit the jackpot by trading away Chris Sale and Adam Eaton this winter, and could move Jose Quintana, Todd Frazier, or Jose Abreu at some point this season. They are looking at one of the best farm systems in all of Major League Baseball.
The three options that stand out as most nearly MLB-ready are Yoan Moncada, the best offensive prospect in baseball, Lucas Giolito, and Reynaldo Lopez. For the Sox, there is little point in calling Moncada up to accrue MLB service time for a bad team. Look for his arrival in September as was the case last year when he was in the Red Sox organization. Giolito is very polished, but struggled in his brief MLB stint with the Nationals last season. Lopez performed fairly well.
Of the two pitching prospects, Lopez would stand to benefit the most by working with Quintana before he is traded. His command has made great progress the past three seasons, but the right-hander still struggles to locate his curveball and changeup at times. Let him learn from Quintana for a few months. With or without Lopez, the White Sox are going to be a very bad team, with James Shields, Derek Holland, and Miguel Gonzalez making up the bulk of their rotation.
