A look at what's happening all around the majors today:
The Cubs can clinch the NL Central for a second straight year with a win against St. Louis or a loss by Milwaukee. Jake Arrieta (14-9, 3.43 ERA) pitches for Chicago, making his second start since missing nearly three weeks with a hamstring injury. The Cardinals counter with righty Carlos Martinez (12-11, 3.63), who gave up seven runs to Chicago on Sept. 15.
After going 59-103 last year, the worst record in the majors, the Twins (82-74) can clinch an AL wild card and their first postseason berth since 2010 with a win at Cleveland and an Angels loss to the White Sox in Chicago....
