ARLINGTON -- Nothing has seemed to go in Scott Feldman's favor since he moved into the Texas Rangers' rotation.
In his last six appearances, all starts, Feldman has received no more than one run of support from the best offense in the major leagues.
That trend continued Thursday night, and the defense faltered behind him with a costly error.
In the end, Feldman lost his sixth consecutive start, as the Arizona Diamondbacks rolled to an 11-3 victory at Rangers Ballpark, avoiding a series sweep.
"I feel like I'm very close to being good," said Feldman, who is 0-6 with a 6.50 ERA this year.
"It's just frustrating to keep going out there and not be winning, but I feel like I'm really close. I didn't think it'd take this long for me to feel like I'm clicking."
Feldman started the game by striking out the side in the first, and the Rangers grabbed an early 1-0 lead in the bottom of the inning. But things unraveled from there.
In the second, Feldman gave up a two-run home run to Jason Kubel.
The Diamondbacks scored two more runs in the third after Mitch Moreland committed his first error of the season.
With two outs and a runner on first, Moreland couldn't come up with a grounder hit his way by Miguel Montero.
The next batter, Lyle Overbay, ripped a two-run double to left, giving Arizona a 4-1 lead.
"That kind of stuff happens," Feldman said. "I've got to get the next guy out and I didn't do that."
Moreland made no excuses for his error, saying he simply missed it.
"It had a lot of topspin on it, and it stayed down on me," Moreland said. "I was up and I should've been down, but that's the way it goes."
Feldman worked a 1-2-3 fifth, but his night ended when he gave up consecutive doubles to Montero and Overbay to start what became a five-run sixth for the Diamondbacks.
Tanner Scheppers relieved Feldman, and gave up a three-run home run to Gerardo Parra. That gave the Diamondbacks a commanding 9-1 lead, and the Rangers never truly threatened it.
All three Texas batters in the sixth struck out, including Ian Kinsler.
Kinsler wasn't pleased with a called third strike by home plate umpire Eric Cooper, and let his feelings be known once he returned to the dugout. Cooper eventually tossed Kinsler.
Kinsler declined comment on his ejection, but said: "Tonight wasn't the best game. We didn't really do anything right. It was a tough one, but we got a game tomorrow night."
Diamondbacks starter Daniel Hudson held the Rangers to one run over the first six innings before giving up a two-run home run to David Murphy in the seventh.
Hudson went seven innings, allowing three runs on five hits with no walks and seven strikeouts.
"Give credit to Hudson, he kept us off-balanced," Rangers manager Ron Washington said. "The guy is a major-league pitcher and he shut us down. I have nothing else to say about it."
The Diamondbacks added two more runs in the eighth on a homer by Montero off Yoshinori Tateyama.
Despite the lopsided loss, Washington hasn't lost any confidence in his team.
Texas will have a three-game lead over the Anaheim Angels in the American League West when it opens a three-game series against Houston tonight.
"We still won the series," Washington said. "Don't forget that."
