"I felt like I could have kept going, but I had a lot of pitches and I expected that," he said.
Through four games, Astros starters have combined for a 2.49 ERA, having allowed six runs in 21 2-3 innings. They entered the game ranked third best in ERA in the American League with a 2.08.
The bullpen has been another matter over the past three games, which the Astros have lost by a combined 19-2.
Cedeno walked the first two batters he faced to load the bases, then watched as Gonzalez botched a potential double play at short, an error that cost the Astros two runs on the play and allowed Yoenis Cespedes to reach base.
Josh Reddick made it 4-0 on a sacrifice bunt by John Jaso, and Josh Donaldson followed a Chris Young walk with an RBI single that scored Cespedes.
"That's a tough error," Porter said. "The ball was hit pretty hard, but at the same time, if he'd field that ball cleanly, it's definitely an easy double play."
Cedeno then hit Eric Sogard with a pitch to again load the bases to end his outing. He was replaced by right-hander Rhiner Cruz, who allowed Crisp's two-run double to make it 8-0.
Straily allowed a single to Chris Carter with two outs in the first inning before retiring 13 of the next 14 batters.
The Astros' next hit came in the sixth when Gonzalez doubled down the right field line.
The Astros scored for the first time in 24 1-3 innings when Altuve drove in Gonzalez with a single to make it 8-1.
Justin Maxwell doubled with no outs in the seventh off Straily. Straily was replaced by Pat Neshek with two outs, and Neshek allowed an RBI single to Matt Dominguez.
Wallace said the team is working hard to regain its form at the plate.
"You can't get too caught up on the numbers, especially this early in the season," Wallace said. "When we get pitches to hit we have to put them in play hard and do damage."
"I think it comes down to rhythm."
