Corbin looks to keep rolling: ARI@HOU, 2:10 p.m.
This series concludes with Arizona southpaw Patrick Corbin looking to repeat his strong performance against the Cubs last week. Corbin held Chicago scoreless and struck out eight through 6 2/3 innings, his longest scoreless outing of 2017.
Right-hander Mike Fiers will start for the Astros. After turning his season around with a promising 10-game stretch in which he went 6-2 with a 2.36 ERA, Fiers has taken a step back of late. He's 0-3 with an 8.41 ERA over his last four starts, allowing seven home runs in that span.
D-backs outfielder David Peralta is expected to rejoin his club Thursday after his wife gave birth to their first child on Monday. It's not yet clear whether he'll return to the lineup against the Astros.
"I would like to have him play as soon as possible," Arizona manager Torey Lovullo said. "I know he was a little sleep deprived. Hopefully, he's caught up in that area. Emotionally, he's probably riding a little high knowing what happened. I think each case is different, so that's why I want to talk to him and see how he's feeling."

Subway Series finale: NYY@NYM, 7:10 p.m.
The Subway Series comes to a close Thursday with the Mets and Yankees taking the field for the second game in Queens. The Yankees will be vying for a series sweep after winning the first three contests by a 14-9 margin. They'll send All-Star Luis Severino to the Citi Field mound, as he looks to rebound from his worst outing of the season. He gave up a career-high 10 runs (eight earned) in 4 1/3 innings, as the Yankees lost to the division-rival Red Sox.
"This is a bad day," Severino said after the game. "I have to keep working. I've got the Mets [next]. I've got to work hard and try to get the win."
The Mets will counter with lefty Steven Matz, who's 0-5 with a 9.51 ERA in his last seven starts.

Nola takes the hill: PHI@SF, 10:15 p.m.
The Phillies head into Thursday's opener against the Giants at AT&T with a red-hot Aaron Nola taking the mound. The young right-hander has been dominant since the All-Star break, going 3-1 with a 1.85 ERA and 44 strikeouts in six starts (39 innings).
Nola is the first Phillies pitcher since current mound regulations were established in 1893 to go 10 consecutive outings without allowing more than two runs in any of them.
Jeff Samardzija will start opposite Nola for San Francisco. The right-hander has historically struggled against the Phillies -- posting a lifetime 8.67 ERA in 10 games (four starts) -- but enters Thursday's game with quality starts in four consecutive outings. He's 3-1 with a 3.29 ERA in that span.
