CINCINNATI (AP) A.J. Pollock drove in two runs with a bases-loaded single in the eighth inning as the Arizona Diamondbacks came back from a 4-0 deficit to beat the Cincinnati Reds 5-4 in the opener of a four-game series Thursday night.
Chris Owings homered and drove in two runs as Arizona sent the Reds to their sixth consecutive loss.
The Diamondbacks loaded the bases against Burke Badenhop (1-3) on Yasmany Tomas' single, Jarrod Saltalamacchia's pinch-hit double and Ender Inciarte's walk, setting up Pollock's two-out hit.
David Hernandez (1-3) pitched a perfect seventh to get the win. Daniel Hudson left the bases loaded in the eighth and Brad Ziegler pitched the ninth for his 22nd save.
Reds' rookie John Lamb, who went six innings in his major league debut last Friday, lasted 5 1-3 innings in his second career start. The left-hander allowed nine hits and three runs with eight strikeouts.
Arizona starter Patrick Corbin (3-4) lasted just two innings. The left-hander allowed eight hits and four runs with two strikeouts.
The Reds, who scored a combined four runs while losing a two-game series to Kansas City on Tuesday and Wednesday, scored that many over the first two innings on Thursday.
Jason Bourgeois led off the first with a single to center and scored on Jay Bruce's sacrifice fly. The Reds added three runs on five hits in the second, including RBI singles by Tucker Barnhart and Eugenio Suarez sandwiched around Bourgeois's run-scoring triple.
Lamb lost his shutout in the fifth, allowing Owings' fourth homer of the season leading off the inning and a two-out run-scoring single by Pollock. Owings added an RBI single in the sixth.
Diamondbacks: Hopes that RHP Jeremy Hellickson's left hamstring injury wasn't too severe were dashed when he couldn't throw on the side on Wednesday, prompting Arizona to place him on the 15-day DL.
Reds: INF Brandon Phillips was available to pinch-hit or pinch-run on Thursday, one day after leaving Cincinnati's 4-3 loss to Kansas City with inflammation in his right biceps tendon.
Diamondbacks: RHP Rubby De La Rosa (10-5, 4.40) hopes to continue his recent hot streak in Friday's start, the first of his career against Cincinnati. De La Rosa is 4-0 with a 2.54 ERA over his last six starts.
Reds: LHP David Holmberg (1-2, 5.95) makes his first career appearance against his former team in the second game of Cincinnati's four-game series against Arizona. The Reds acquired Holmberg in December 2013 as part of a three-team trade in which Cincinnati sent C Ryan Hanigan to Tampa Bay.
