"That's way too many pitches, obviously," Feldman said. "I've got to come out better than that. I settled down a little bit, but next time I've got to come out better in the first."
Feldman retired Delino DeShields to start the game and got Nomar Mazara to hit a grounder to shortstop Carlos Correa, who misplayed it for an error. Prince Fielder followed with a two-run homer on an 0-2 pitch Feldman hung.
"I feel like the 0-2 count there, I've got to make a better pitch," Feldman said. "[Fielder's] a great hitter, but at the same time, when you're that far ahead in the count, you can't throw him a strike like that. I was trying to bounce that one and didn't get it there, and he put a good swing on it."
In the Astros' last turn through the rotation, only Dallas Keuchel -- eight scoreless innings on Friday against Detroit -- has managed to finish the sixth inning. Keuchel has two of the Astros' five quality starts; Mike Fiers, Collin McHugh and Feldman each have one.
"We're leaning on our bullpen pretty heavily," manager A.J. Hinch said. "We have a good bullpen, and certainly guys like [Chris Devenski] and others in the middle have stepped up and done well. It's part of it. I think our guys are just putting themselves in a hole a little bit and using up a lot of pitches and a lot of taxing innings.
"It hasn't come easy early in the season and early in the games. For the most part, I believe they're going to come back and bounce back out of this. It's important for our guys to put up zeros, even if they don't last deep into a game, try to keep the game close early."
Feldman is aware of the workload of the bullpen and says the starters will get it turned around.
"We obviously are trying our best to get deep into the game, and those guys in the 'pen have been carrying a heavy load," he said. "We're going to get better and keep improving as the season goes on, and hopefully none of this five-and-dive-type stuff like tonight."
