A look at what's happening all around the majors today:

SADNESS

More from FoxSports

The Miami Marlins play for the first time since 24-year-old pitcher Jose Fernandez was killed in a boating accident. Popular and productive, Fernandez had been scheduled to start this game at home against the Mets. There were tributes at Marlins Park and all around the majors after he died early Sunday.

HARPER CHECK

Washington star Bryce Harper is getting X-rays on his left thumb. The reigning NL MVP was hurt Sunday on an awkward slide after Pittsburgh third baseman Jung Ho Kang made a fake tag. Harper had surgery to repair a torn ligament in the same thumb in 2014. The NL East champion Nationals host Arizona.

CLINCH CLUB

The Cleveland Indians can wrap up their first AL Central championship since 2007 with a win at Comerica Park. Cy Young candidate Corey Kluber goes for his career-high 19th win. He's 3-0 with a 1.88 ERA against Detroit this season. The Tigers are 1 1/2 games behind Baltimore for the second AL wild-card spot.

ACE APP

J.A. Happ tries for his 21st win when Toronto hosts the Yankees. The Blue Jays lead the AL wild-card chase by 1 1/2 games over the Orioles, thanks in big part to Happ (20-4). Luis Severino (3-8) starts for New York.

BACK AGAIN

Sonny Gray will come off the disabled list to make his first start in nearly two months for Oakland. The 26-year-old righty hasn't pitched in a game since Aug. 6 because of a strained forearm.
