Josh Naylor Just Joined Billy Hamilton in Unreal Baserunning History

Naylor is not the guy you think of a base stealer, but he has been with the Seattle Mariners.

Since arriving in a trade with the Arizona Diamondbacks right before the trade deadline, Josh Naylor has made quite the impact with the Seattle Mariners.

First off, he's homered three times since arriving in Seattle, including hitting a massive 450-foot blast in Wednesday's 8-6 win over the Chicago White Sox.

Second off, he's become a surprising base stealing threat, and he's swiped four bags in the last two games. Not thought of a speedster, Naylor has created all kinds of history in his new surroundings.

Per @MarinersPR:

Josh Naylor is the first @MLB player with 10+ stolen bases in his first 12 games with a franchise since Billy Hamilton for the Cincinnati Reds from Sept. 3-25, 2013.

One of the fastest runners in the 21st century, Hamilton stole 326 bases over parts of 11 seasons in the big leagues. He registered 56 steals or more in four consecutive seasons from 2014-2017.

In addition to Hamilton, Naylor also joined Baseball Hall of Famer Ichiro Suzuki in team history:

Josh Naylor is the second player in @Mariners history with 2+ stolen bases and 1+ home run in consecutive games, joining Ichiro Suzuki (Sept. 8-9, 2011).

Naylor, 28, is hitting .290 this season with 14 home runs and 65 RBIs. He also has 21 steals and a .357 on-base percentage.

After the win on Wednesday, the Mariners are now 62-53 and just two games back in the American League West. They also hold a one-game lead on the New York Yankees for the second wild card spot.

They'll play the White Sox on Thursday at 1:10 p.m. PT.
