I've been saying for years that corner OF defense isn't worth worrying about. However, I don't feel that way about C, SS, 2nd base, and to a certain degree, CF. Catcher handles the ball on almost every pitch. SS and 2nd base HAVE to turn ground balls into outs, virtually every time, and there are a lot of ground balls between the two of them. The SS or 2nd baseman are going to take every relay from the OF. They handle the ball, a lot. So IMO, no...in addition to the errors, Polanco just doesn't turn enough ground balls into outs.
