CINCINNATI - Arizona's Jake Lamb and Cincinnati's Eugenio Suarez each hit two homers Thursday, but here was the difference:
Lamb's homers drove in six runs and his teammates hit two more. Suarez's homers drove in two runs and his teammates were no help.
Arizona's Patrick Corbin pitched into the eighth inning during an emergency start, leading the Diamondbacks to a 12-2 victory while the punchless, pitching-less Reds fell to 1-6 since the All-Star break - all at home.
The last-place Reds have allowed 10 or more runs in four of those losses. They have been outscored 63-20 in the seven games.
“The problem is clear,” Reds manager Bryan Price said. “Unfortunately, we’ve given up double figures in runs in four of these games. That’s the constant thing. We need to pitch better. It’s a worn-out record. I’m tired of talking about it.”
The Reds have given up 166 homers, the most in the majors. They’re on pace to break their major league record of 258 allowed last season.
Lamb homered in the first inning off Luis Castillo (1-3) and again in the ninth. Gregor Blanco and Ketel Marte added two-run shots.
Suarez homered off Corbin in the fourth inning and tagged ex-Red J.J. Hoover in the eighth.
Castillo retired 18 of 20 batters after Lamb's first-inning blast, but the bullpen gave up eight runs.
Corbin lasted a season-high 7 1/3 innings. The left-hander pitched out of a bases-loaded, no-outs threat in the fourth to hold the lead.
Arizona's scheduled starter, Taijuan Walker, was scratched after his wife went into labor Thursday morning. Corbin (7-9) was moved up a day and wound up with his first victory since June 16. The left-hander had gone 0-3 in his previous five starts.
Billy Hamilton doubled in the first inning and was thrown out by catcher Chris Iannetta while trying to steal third. It was the second time in two games that Hamilton was caught stealing. He’s been caught seven times and has stolen 40 bases, most in the majors.
Paul Goldschmidt went 0 for 5 with four strikeouts, ending his hitting streak at 11 games. It also ended his road hitting streak at 17 games, one shy of the Diamondbacks record.
Walker was placed on paternity leave, and RHP Matt Koch was called up from Triple-A Reno. Manager Torey Lovullo will rearrange his weekend pitching plans with Walker gone, and he might use Koch to start one game.
Diamondbacks: Martinez was out of the lineup with the bruised hand, sustained in his second at-bat on Wednesday night. "A crazy 24 hours," he called it while headed to get treatment on Thursday morning. Lovullo is hopeful he can return over the weekend.
Reds: SS Zack Cozart got a day to rest. He missed time last month because of a strained right thigh that is not fully healed.
Diamondbacks: Arizona opens a three-game series Friday against visiting Washington. The Diamondbacks lost two of three at Nationals Park in May and are 3-7 against the Washington during the last two seasons.
Reds: Homer Bailey (2-3) faces Jose Urena (7-4) when the Reds open a home series Friday against Miami. Bailey makes his sixth start since returning from elbow surgery. He gave up eight runs in four-plus innings of a 14-4 loss to the Nationals last weekend.
