Badly in need of innings from its "Kiddie Korp" of rookie starters, Raisel Iglesias was up to the task but a line drive by Wellington Castillo hit a butter fingered fan two rows deep in the leftfield bleachers and plopped back on the field. A Keystone Cops act ensued as the throw from leftfielder du jour Jason Bourgeois made it all the way through the infield. Joey Votto had to chase it down.
Iglesias gave the Reds what they needed. He finished seven innings, allowing one run on three hits and three walks while striking out 13.
The umpires reviewed the play for 48 seconds before awarding Castillo his 16th home run.
The Reds left two runners on against Chase Anderson who has been bounced back and fourth between Triple A Reno and the big club. The Reds got a leadoff single from Ivan De Jesus Jr. in the second but he was erased on a double play. Bourgeois hit a one-out single int he third but a double play got him as well. In the fifth, De Jesus Jr. walked and rookie Ryan LaMarre got his first Major League hit to put runners at first and second with one out. Iglesias squared to bunt but pulled the bat back to take a full swing. He lined the ball toward rightfield but Paul Gosldschmidt speared it as he charged for the bunt and beat LaMarre back to first base for an unassisted double play.
Reds' fielding helped the Diamondbacks take a 2-0 lead in the sixth. Ender Inciarte walked and stole second. Goldschmidt hit a ground ball wide of first against the shift. Votto speared it back handed on a short hop but threw it by Iglesias covering first. The ball trickled toward the dugout and Iglesias threw it over Brayan Pena's head, allowing Inciarte to score and Goldschmidt to advance .
David Peralta hit a two-run home run off Jumbo Diaz in the eighth. It was Peralta's 13th of the season.
