I think his defensive skills are better than Turner
Trea Turner has shown to be a solid to above average short stop in the minors and majors.
Wilmer Difo still has a limited sample size at short and has put up great defensive metrics and passes eye test.
I still think Trea Turner is the short stop since he plays every day and we don't want to move him around, but Wilmer Difo just making the question be asked who is better at the spot is a credit to him.
