Because of Joey Gallo's immense power, Houston Astros manager A.J. Hinch used a unique tactic to ensure the Texas Rangers slugger wouldn't get on base.

MLB.com's Daren Willman showed how the Astros positioned their defense with a four-man outfield that had third baseman Alex Bregman in left field during Gallo's first-inning at-bat:

The Athletic's Jake Kaplan noted hitters like Jay Bruce, Justin Bour, Logan Morrison and Matt Adams saw this four-man outfield alignment against the Astros in spring training.

Hinch explained to Kaplan the reasoning behind the strategy:

“It's not a gimmick play as much as it's a coverage. Like any shifting that you do, you're trying to put guys in a position where we can cover the most ground that makes the most sense. And some guys, when you look at fly-ball rates and you look at where they actually hit the ball, you don't want to defend an area where there's minimal chance of those guys hitting it, and a lot of times that's on the ground on the opposite side of the field.”

Chicago Cubs manager Joe Maddon tried to use the four-man outfield against the Cincinnati Reds last season, but Joey Votto got a double out of it.

Given all the analytics being used across MLB today, teams could look to use unique defensive alignments like the four-man outfield more often if odds suggest it is more likely to result in an out.
