Would you slam a vat of Italian dressing for $1,000!?!
That's a question Tim Lincecum apparently asked one of his teammates back in 2018 ... and, according to the salad-topping drinker, the answer was YES!!!
Tyler Wagner -- a former Texas Rangers pitcher -- revealed the story on social media late Thursday night ... and it's hilarious, mostly because he provided photographic proof that it all went down!
Wagner says when he and Lincecum were teammates in Texas about three years ago ... the two-time Cy Young winner bet him a grand that he wouldn't drink the leftover dressing that came with the team's salad.
