Forget his defense. He can't hit either.
Duran's real problem, at least in the near term, is that Cora is knee deep in good hitting outfielders, especially now that Dalbec, the August rookie of the month thanks to a 1.200 OPS, 7 dingers, and 21 rbi's, looks like a lock at 1b.
Even with Kike out, Cora has much better choices than Duran: Verdugo, Renfroe, and JDM/Schwarber--or, heaven forbid, Santana.
When Kike returns, Duran moves to pinchrunner/batboy because he can't hit and he can't field.
