CINCINNATI — Raisel Iglesias did more than his part trying to break Cincinnati’s losing streak.
The Reds’ hitters, not so much.
Iglesias struck out 13 in seven innings but the Reds matched their worst skid of the season with their ninth straight loss, beaten by the Arizona Diamondbacks 4-0 Sunday for a four-game sweep.
Iglesias (3-5) put up the highest strikeout total by a Reds rookie since Gary Nolan fanned 15 Giants in 1967. He allowed two runs, one of them earned, and three hits and three walks.
“Unfortunately, we didn’t get any offense and gets a loss by his name,” Reds manager Bryan Price said.
The Reds’ bullpen has been worn down by the lack of innings that its starting rotation of five rookies has turned in.
Iglesias has been a bright spot, turning in his fifth straight quality start and second consecutive seven inning effort.
“My changeup has been better the last two games,” Iglesias said.
Price was thankful for Iglesias’ effort.
“What he did was save our bullpen for tomorrow,” Price said.
Chase Anderson (6-5) pitched shutout ball into the seventh inning and Welington Castillo and David Peralta homered.
Anderson (6-5) gave up five hits in 6 2-3 innings, walking three and striking out two. He was optioned to Triple-A Reno on Tuesday and recalled Thursday when Jeremy Hellickson went on the disabled list,
Relievers Addison Reed and Matt Reynolds finished up the shutout. Reynolds, coming back from Tommy John surgery, made his first big league appearance since June 2013.
Castillo put Arizona ahead with a solo home run with two outs in the fourth. It was his 16th homer of the season and 14th since being acquired from Seattle in early June 3.
Castillo’s line drive bounced out of the seats and back on to the field, prompting a 46-second crew chief review to make sure it was a home run.
Arizona capitalized on two errors on one play to make it 2-0 in the sixth. With Ender Inciarte on second, Paul Goldschmidt hit a chopper wide of first that Joey Votto caught backhanded, but his throw to Iglesias at first was low and literally booted by the pitcher for an error on the first baseman. Inciarte rounded third, and Iglesias’ throw to the plate sailed over catcher Brayan Pena’s head for the second error.
“I was angry with myself. I had time to make a better throw,” Iglesias said.
Peralta added a two-out, two-run homer in the eighth.
Diamondbacks: CF A.J. Pollock got the day off. He was 11 for 15 with a double, a home run, five runs and three RBIs in the first three games of the series.
Reds: Brennan Boesch was scratched from a start in right field because of a sore right ankle. He fouled a ball off it Saturday.
Reds: What had been scheduled as a day off turned into the makeup of a game against Detroit postponed by rain from June 18. RHP Keyvius Sampson (2-2, 4.43), who wasn’t with the Reds until July 30, is Cincinnati’s scheduled starter.
Ryan LaMarre got his first major league hit in the fifth. “I was happy to get it, but after that it was about winning the game,” he said.
Collin Balester’s contract was selected from Triple-A Louisville before the game to give the Reds a fresh arm. He pitched a scoreless inning in his first big league appearance since May 16, 2012, with Detroit.
