Josh Naylor just set a Seattle Mariners stolen base record. Yeah, 250-pound first baseman Josh Naylor. In Naylor's first four games with the Mariners, he has stolen four bases. He didn't swipe one in his debut, then has gone 1-2-1 in the last three games.

In a move that highlights their aggressive strategy before the MLB Trade Deadline, the Seattle Mariners made headlines by acquiring first baseman Josh Naylor from the Arizona Diamondbacks on Thursday.
