After resting most of their regular hitters, the Arizona Diamondbacks came through with a big win to avoid falling further behind in their playoff chase.
Christian Walker and Chris Owings homered off Cole Hamels, and Robbie Ray held the Cubs to one hit over six innings as Arizona beat the NL Central-leading Chicago Cubs 9-0 Wednesday night.
"We were not throwing in the towel today, and I think everybody in that dugout knew it," Diamondbacks manager Torey Lovullo said, promising that his "main guys" will be back in the lineup for the next game.
Walker and Owings, mainly used off the Arizona bench, were part of a Diamondbacks lineup that featured only two regulars in the field — Nick Ahmed and Ketel Marte. The group did most of its damage against Hamels (9-10), who had yet to lose a start since joining the Cubs via trade from Texas on July 27.
"What can you say? You get the understudies into a ballgame, they bring a certain energy to the start of a game and we end up playing downhill baseball with that big three-run home run by Walker," Lovullo said. "I felt like the time was right (to rest regulars) and it worked out well."
Arizona avoided a series sweep, put an end to a four-game losing streak and gained a game on St. Louis for the second wild card, although they still trail the Cardinals by five games. The Diamondbacks remained six games out behind the first-place Los Angeles Dodgers in the NL West.
Ray (6-2) struck out eight and walked four. Walker and Owings drove in three runs each.
"My fastball away was really effective," Ray said. "Honestly I didn't look at our lineup before I went out there."
Jeff Mathis added a two-run home run off Cubs reliever Allen Webster, who'd been called up from Triple-A Iowa earlier in the day.
The Cubs' lead in the NL Central dropped to 2 1/2 games over Milwaukee, which beat Cincinnati earlier Wednesday.
The Diamondbacks tagged Hamels for four runs and five hits in the first inning. Walker's homer, his third of the season, sailed onto the overhang in left-center field with Ildemaro Vargas and Marte on base.
Later in the inning, Owings blooped a single to shallow right field, and Patrick Kivlehan scored after he'd tripled to make it 4-0.
Kivlehan became the second Diamondback this season to triple multiple times in a game when he did it again in the sixth inning. He scored on Ahmed's single, and Ahmed scored on Owings' fourth home run of the year.
"Basically going out there with nothing to lose," Owings said.
"We knew we had to go out there and do a good job," Kivlehan said. "We just tried to keep it simple and not put too much pressure on ourselves."
Mathis went deep to left in the eighth for his first home run of the season.
Hamels allowed seven runs and nine hits, tying the most earned runs he's given up in a start this season.
"They got key hits all at the right time," Hamels said. "Three-run home runs, two-run home runs, they definitely hurt and makes it tough to come back."
The Cubs completed a stretch of 30 scheduled games in 30 days with 18 wins.
"Sign me up," Cubs manager Joe Maddon said. "We will take that every day of the week. I'm proud of my guys. We won five of our last seven through all this in different cities."
