When I pointed out outfield assists, it wasn't to imply Beni has the best arm, only that he isn't as inept as a few posters here insist. If a ballplayer leads the league in a positive stat at his position, he's at least doing his job. We also know the eye-test shows us that baserunners stopped running on Dewey Evans or Mookie -- affecting their numbers... or that the Red Sox won rings with true rag arms in center with Damon or Ellsbury.
It was only two years ago that Benintendi was chosen by professional observers as a finalist for the AL Gold Glove in left field. He also led the MLB postseason in runs scored in '18 and tied for the AL lead in hits with JD Martinez. But bodies can change quickly (Ozuna won Gold in '17 and now he's a DH). Maybe Andrew's dealing with a recurrent arm or leg injury; we shall see.
