If Evan Gattis can play catcher ( 6' 4" 270lbs ) then Sano can play 3rd. The big thing with Sano has been and always will be: he has the potential to out hit any defensive liabilities. If he can't ( reduced hitting / increase to really horrible defender ) the DH position was created specifically for ballplayer like that. The little we've seen of Sano at 3rd, he's made improvements in his throwing and footwork, i.e. he's not patting the ball a couple times in his glove before throwing. Unfortunately, because of the time of year, poor record and the need to workout MiLBers at different positions, Sano won't get the full-time workout at 3rd most would like to see. I liked seeing Polanco playing 3rd very well. SS, too. Another young player that can play 3rd should Sano pull another nutty. This team is developing, progressing and moving on. Some will be left behind. Can't wait for the Aug 1st roster expansion!
