STORYLINES

Staying Hot at Home? The Astros are now 18-7 at home in 2020 after taking two of three from the Texas Rangers. Conversely, the Diamondbacks are 8-19 on the road. It's a perfect blend for the Astros to continue their winning ways at home and position themselves in a more ideal spot for the playoffs.

Staff Settling in: Greinke and Urquidy taking the bump in a three game series brings a sense of normalcy to the Astros rotation. The days of Brandon Bielak and Luis Garcia getting starts are in the past. McCullers looked fantastic in his outing against the Rangers, and Justin Verlander is close to returning. That is a staff capable of winning a World Series.

Sinking Ship: The Astros win over the Rangers Thursday night kept the Mariners three games back of the Astros with just 10 games left to play. The Astros also own the tiebreaker over Seattle, meaning Seattle really needs to make up four games to jump the Astros for a playoff spot. Of course, the Astros' series in Seattle starting Monday will play a big role in that.

PREDICTION

The Diamondbacks are reeling, and the Astros are a force at home. Zac Gallen presents some problems for a slumping offense, but the Astros break out against Weaver and Bumgarner to take two of three.
