Cubs one step closer to having on-site sports betting at Wrigley Field

The Cubs still need approval from the City Council, Illinois Gaming Board and the National Park Service.

Ian Happ drove a two-out, two-run homer in the ninth inning to sour what could be Jon Lester's final career start, lifting the Chicago Cubs over the St. Louis Cardinals 6-5. Lester, 37, hasn't declared whether he intends to come back for a 17th season. 

The left-hander pitched for the Cubs for six seasons, including the 2016 World Series team. 

Happ drove a 2-0 pitch from Luis Garcia over the center-field wall for his career-high 25th home run of the season. 

The blast made a winner out of Jason Adam, who pitched a perfect eighth.
