LEADING OFF

A look at what’s happening around the majors today:

ZEROED IN: Zack Greinke makes his Houston debut, joining an Astros rotation that is on quite a roll. Justin Verlander, Gerrit Cole, newcomer Aaron Sanchez and the starters for the AL West leaders are 14-1 in their last 17 games — the Astros held Seattle to a total of seven hits in a three-game sweep over the weekend, including a combined no-hitter.

Greinke (10-4, 2.90 ERA) was acquired from Arizona on Wednesday. He’ll see a lot of familiar faces when he starts against Colorado at Minute Maid Park. Trevor Story has hit five home runs off Greinke, tied with Carlos Gonzalez and Jason Giambi for the most against the right-hander. Rockies star Nolan Arenado, however, hasn’t homered in 75 at-bats vs. Greinke.

HE’S BACK: Mike Foltynewicz returns to the Atlanta rotation after getting demoted to the minors. He’ll start against the

AL Central-leading Twins at Target Field.

A 13-game winner and an AllStar for the Braves in 2018, he struggled to regain that form after battling elbow trouble in spring training. He was sent to Triple-A on June 22 after going 2-5 with a 6.37 ERA in 11 starts.

Foltynewicz will take the place of Kevin Gausman, who was claimed on waivers by Cincinnati. Gausman was 3-7 with a 6.19 ERA.

NOW WARMING: The Cubs plan to take a closer-by-committee approach after putting Craig Kimbrel on the 10-day injured list because of inflammation in his right knee. Kimbrel is 0-2 with a 5.68 ERA and nine saves in 14 games. He got a late start this year after he finalized a $43 million, three-year deal with Chicago in June.

The NL Central leaders also will be without All-Star catcher Willson Contreras for four weeks because of a strained right hamstring. He is batting .275 with 19 homers in 87 games.
