How's Sano's defense at 3rd going? From what little I saw of Polanco at 3rd, he looked pretty good. Maybe not a strong enough arm? SS? Maybe he's not getting enough reps to smooth out his throwing issues? Outfield? Where the heck is that coming from? Just skimming Polanco's MiLB record, he played 10 games in rookie ball in 2011.
Trade Nunez, an infielder, for a MiLB pitcher who needs more MiLB time, opening a spot to call-up an infielder, i.e. Polanco. Almost like it was planned.
At this point, I believe there is only one logical thing to do: Send a semi load of those throwback jerseys to Sale. See if he throws another nutty and the White Sox see it as a need to trade him for ANYTHING! http://sportsmockery.com/wp-content/uploads/2015/08/2012-3-19-SoxShorts.jpg
