12:32 PM PT -- 11/02 -- Okay, the numbers are in ... and Jon Lester dropped a grand total of $47,094.90 on his free beer giveaway!
Here's the breakdown ... Lester bought 4,838 Miller Lites for fans in the Chicago area between Friday and Sunday -- totaling around $31k in booze alone.
And gratuity?? Lester dropped a 34% tip (a nod to his jersey number) -- which came out to $16,012.27!
And he's got the receipts to prove it!
"Thanks for coming out this weekend y’all," Lester tweeted.
"Shout out to all the bars, their staff, and those cheers-ing from afar! Whether this is goodbye or see you next year, I love you Chicago! #JonsTab"
Dude loves Chicago!!
Jon Lester's future in Chicago is uncertain ... but one thing is guaranteed -- Cubs fans are getting LIT on the ace's dime this weekend!!!
The 36-year-old pitcher is expected to get a $10 million buyout and hit free agency this offseason ... so he wanted to say "thank you" to his fans over the past 6 years by buying their "first round" of beers at several spots in the Windy City this weekend.
"Regardless of what's next I want to thank the fans for the past 6 years," Lester tweeted Friday morning.
"So this weekend (10.30-11.1) I'm buying y’all my favorite beer."
All fans gotta do is hit up Hopsmith Tavern, The Lodge, Butch McGuire's or She-nannigan's -- which are all on Division Street in Chicago -- and they get a free Miller Lite!!!
"Just tell em to put it on #JonsTab."
It's a very kind gesture on Jon's part, but don't worry -- dude's reportedly made more than $190 MILLION in his career ... so it's just a drop in the bucket keg.
