"It's pretty set," Porter said of the roster. "Most of the guys that aren't playing [Sunday], the reason they're not playing today is they're on the team. [Carlos] Corporan is catching, just because he's our backup catcher and I want to make sure he's ready to go."
Saturday's starting nine could easily be a regular lineup for Houston, as newcomer Dexter Fowler complemented established starters such as Jason Castro, Jose Altuve and Matt Dominguez.
They didn't leave a strong final impression, as Veracruz starter Tomas Solis shut them down through three innings. Fowler did add a home run in the fourth, but Astros regulars managed just three hits in four innings against the Mexican League Triple-A affiliate.
Porter said he's not concerned about that performance, instead preferring to emphasize health over reps at this point in the spring.
"I'm excited about getting through the spring mostly healthy," Porter said. "As long as nobody slips on a banana peel between now and Tuesday, we'll be good."
