Evan Gattis and Tyler White matched their look so efficiently it's hard to tell who's who

There's a Pink Floyd tribute band called Which One's Pink? that travels around playing the songs made famous by the legendary English prog-rock band. This is relevant because there is no real mystery regarding their name -- they are not the actual Pink Floyd.
But when it comes to discerning whether a hoodie-wearing, bearded Astro is Evan Gattis or Tyler White, we have to ask: Which one's White?

That was the scene in the dugout during Houston's 5-4 win over the Tigers on Tuesday at Comerica Park, and kudos to you if you're able to correctly tell which one's which (spoiler alert: White's on the right).
