The Mariners apparently added an unstoppable base-stealing specialist when they acquired Josh Naylor at the trade deadline. They just didn't know it at the time.

Even the most ardent Josh Naylor fan wouldn't have seen this coming. Naylor has played 11 games since his trade to the Seattle Mariners. In that span, Naylor has eight stolen bases. He's a perfect 8-for-8, too, not having been caught. No one in this span has more steals than Naylor does, per Just Baseball.
