Tony Cingrani (6-3) pitched 3.2 innings before feeling discomfort in his lower back and after being looked at by the Reds trainer, Dusty Baker opted to remove him from the game. Cingrani started the inning by allowing a home run to Martin Prado and then walked Paul Goldschmidt. He was able to pickoff Goldschmidt in between first and second, but Aaron Hill followed with a double to left to bring out pitching coach Bryan Price, who then called on the trainer.
Cingrani is already filling the void left by Johnny Cueto, who is nowhere near returning from his stint on the disabled list. There is no word yet on how severe the injury is or if he'll miss any starts. Pedro Villarreal and Greg Reynolds have each made spot starts this season.
Alfredo Simon filled in and was able to keep the Diamondbacks (65-59) off the scoreboard over the next 2.1 innings to keep it a 1-0 game. On the other side, Patrick Corbin (13-3) dominated Reds (71-55) hitters holding them without a run through the first seven innings.
Arizona gave Corbin some extra insurance when Sam LeCure allowed three straight singles and then J.J. Hoover allowed a grand slam to Goldschmidt for his league tying 31st homer of the season.
The Reds finally got on the board against Corbin when Chris Heisey hit a two run homer into the left field seats. Corbin settled in an retired the final six hitters for his second complete game of his rookie season. In two appearances against the Reds, Corbin has tossed 17 innings and allowed three runs while striking out 15.
The two teams continue their four game series on Wednesday as Brandon McCarthy (2-7) faces Mike Leake (10-5). Leake is looking to turn around his month of August in which he is currently 0-1 in three starts with a 6.35 ERA.
