Jon Lester may have thrown his last pitch for the Chicago Cubs.

He signed a six-year, $155 million deal with the Cubs before the 2015 season and helped them finally win a World Series the year after.

Lester, 36, bought beers for patrons over Halloween weekend at four Chicago bars, tweeting out his tab, which included a 34% tip, the same number he wore on his uniform.

Lester spent $47,094.90 between Friday and Sunday, which included $31,082.63 on Miller Lites and $16,012.27 in gratuity.

The Cubs turned down a $25 million option on his contract over the weekend, but the sides say there is still a chance he could return on a lesser deal.
