A look at what's happening all around the major leagues today:
A KEY MATCHUP
San Francisco rookie Chris Heston is set to start in Miami, fresh off being honored at Marlins Park. He's from Palm Bay, Florida, about 170 miles up the highway, and was presented with the keys to the city by its mayor to celebrate Heston's recent no-hitter against the Mets.
Red Sox left fielder Hanley Ramirez could return to the lineup after missing six straight starts. He's been out since getting hit in the left hand by a ball off the bat of teammate Xander Bogaerts. Ramirez tops Boston with 15 homers and 38 RBIs. Outfielder Rusney Castillo is up from Triple-A and with the team in Toronto, but not on the active roster - he's there on a standby basis in case Ramirez needs to go on the disabled list.
Astros rookie Vincent Velasquez tries again for his first win in the majors. He's started four times since making his big league debut in June and hasn't gotten a decision in any of them. The 23-year-old righty has been helped by strikeouts but hurt by walks going into this outing vs. the visiting Royals.
GET OVER IT
Twins righty Trevor May tries to get past the worst start of his young career. He retired only one batter in Milwaukee last Friday, giving up six runs on six hits in a 10-4 loss. He also had a throwing error. He's matched in Cincinnati against Johnny Cueto, who's making his sixth start since returning from an inflamed elbow.
ON THE MEND
Brewers outfielder Khris Davis begins a rehab assignment at Class A Wisconsin. He's been on the disabled list since May 31 because of torn cartilage in his right knee.
