Kyle Busch Gives Wife Props For 'Inches' Roast, 'She Played That Well'

NASCAR star Kyle Busch is giving credit where it's due ... telling TMZ Sports he can only applaud his wife, Samantha, for ruthlessly trolling him over "inches" last week.

In case you missed it -- one of the closest finishes in NASCAR history went down in the Ambetter Health 400 at Atlanta Motor Speedway last Sunday ... with Busch, Daniel Suarez and Ryan Blaney being neck and neck (and neck) right up until the checkered flag.

The 2015 and 2019 Cup Series champion addressed his third-place finish after the race -- going to Instagram and admitting he "Needed a couple inches📏" in order to come out on top ... to which Samantha hit him with a sick burn.

"I’ve been telling you that for almost 20 years 😜" Sam wrote in the comments.

OUCH!!!

We caught up with Busch this week and asked about his wife's friendly jab ... and even he's admitting she got him good.

"I think I left the door wide open for those sorts of comments with how I scripted my text underneath my post, so she played that well."

As for the actual race, Busch broke down the "chess game" he was trying to execute in the final laps ... and how Suarez was able to use his own strategy against him.

But, all things considered, the driver of the No. 8 car said he was able to keep his composure in the end (per usual) ... and is thrilled they were all able to cross the finish line without crashing.
