Quit smoking ... get a brand-new Maserati???
That's the deal Josh Donaldson made with his mom ... and when the MLB superstar paid up his side of the bet with the $70,000 whip -- Momma Donaldson's reaction was PRICELESS!!!
The Atlanta Braves stud says he made the pact with his mom a couple of years ago ... saying if she cut out cigarettes, he'd deliver a pricey ride as a present.
Well, sometime recently, she reached the two-year clean mark ... so he filmed himself giving her the Maserati, and the footage is amazing.
The third baseman's mom goes absolutely bananas when she sees the car ... jumping into his arms and screaming wildly.
Seriously, it's the best.
"2 years of not smoking and here is her early Christmas present," Donaldson said. "Trust me you are going to want to watch this."
The vid is so amazing ... a bunch of MLB stars weighed in, with JD Martinez calling it the "best reaction ever" and Ian Kinsler saying, "That's amazing."
By the way, if you're wondering how the new ride will affect Donaldson's checkbook ... don't fret -- the dude is expected to sign a MASSIVE contract in free agency this offseason!!!
