Goldy homer all D-backs need to down Dodgers

Cahill, bullpen make Goldschmidt's early homer stand up as D-backs take down Dodgers 2-1.

PHOENIX (AP) -- Brad Ziegler and the Diamondbacks are stayin' alive in the NL West.

Paul Goldschmidt hit a two-run home run in the first inning and Trevor Cahill and three relievers made it stand up in the D-backs' 2-1 win over the Dodgers on Monday night.

With Los Angeles' fourth loss in a row and Arizona's third straight win, the Dodgers' magic number to clinch the NL West remained four. The D-backs' win also means the Dodgers will need to take the final two games of the three-game series to celebrate at Chase Field.

"Until we are mathematically eliminated, we have to win every night," Ziegler said. "We've got to go at it, especially when we are playing the team we are chasing.

Los Angeles has lost 11 of 12 as the Dodgers' once 13 1/2-game lead over Arizona only has shrunk to 9 1/2 with 12 games to play.

The Diamondbacks are only in slightly better shape in the NL wild-card race, trailing the trio of the Pirates, Cardinals and Reds by eight games and the Nationals by three.

"We can't worry about what they are all doing," Ziegler said. "We have to go out and play our game."

The Diamondbacks managed only two hits against Dodgers starter Hyun-Jin Ryu, marking the third time in club history they have won with two hits or fewer.

"We were fortunate but sometimes you have to win 2-1 with two hits," manager Kirk Gibson said. "We got two hits but we made the most of them."

Goldschmidt raised his NL-leading RBI total to 116 with his 33rd home run, which came in the first inning off Ryu (13-7). Goldschmidt has homered in each of his last two games after an 83-at-bat drought.

"He threw a fastball first pitch, and I was looking for something over the plate," Goldschmidt said. "(Ryu) pitched great."

Ryu went the distance for his second complete game, allowing only the two runs on two hits in eight innings. He walked one, struck out four and retired 23 of the final 24 batters he faced.

"I threw 100 pitches, but that one pitch was the decision-maker of the game," Ryu said. "It was an error on my part, I believe, no matter how good a pitch it was. If it is a home run, it's a mistake."

Cahill (7-10) won for the fourth straight decision, holding Los Angeles to one run on two hits over 5 2/3 innings.

Brad Ziegler pitched the ninth for his 11th save, but not without some drama.

Michael Young hit a pinch-hit single to center, and Skip Schumaker followed with a single to left. Juan Uribe tried to bunt the runners over, but Ziegler fielded the ball and threw to third to force Young for the first out. Nick Buss then hit a soft bouncer to first for the second out as the runners advanced.

Mattingly then sent up Matt Kemp, who was activated off the 15-day disabled list earlier Monday. Ziegler got ahead 0-2 on two swinging strikes, wasted a pitch and then struck out Kemp on a lunging swing at on a curveball well low and outside.

"I've faced him a lot even before I got to Arizona, facing him in batting practice," Ziegler said. "I know what he's trying to do, and he knows what he wants to do against me. Luckily, I came out on top tonight."

Cahill was nearly untouchable over the first five innings, allowing only a single by Punto to start the game and a two-out walk to Puig in the first before retiring the next 13 in a row. But the right-hander quickly ran into trouble in the sixth with the Diamondbacks still holding a 2-0 lead.

Cahill walked Ryu, Punto doubled to the wall in left-center and Mark Ellis walked to load the bases. Cahill retired Adrian Gonzalez on a line drive to left, and the runners held, but he then walked Puig to force home Ryu and cut the lead to 2-1.

"He's done that in the past," Gibson said of Cahill. "He just starts to lose it. You could just see he was aiming the ball."

But Josh Collmenter came in on a double switch and escaped the jam, striking out A.J. Ellis and getting Schumaker on a broken-bat grounder to second to leave the bases loaded.

Collmenter threw 1 2/3 perfect innings, and David Hernandez hit Mark Ellis with a pitch but stranded pinch runner Dee Gordon at first in the eighth.

"Our pitchers have been doing unbelievable lately," Goldschmidt said. "Our offense hasn't always been there, but they've been tough."

NOTES: Arizona won for the third time in franchise history while finishing with two hits or fewer. ... Goldschmidt is tied with Reggie Sanders for eighth place on the Diamondbacks' single-season home run list and moved into sole possession of third place in RBIs behind Matt Williams' 142 in 1999 and Luis Gonzalez's 142 in 2000. ... Cahill has not pitched past the sixth since Aug. 22, a span of four starts. ... Ryu's other complete game came on May 28, when he threw a two-hit shutout against the Angels. ... Kemp had played only once since July 5, going 3 for 4 with a double and homer before spraining his left ankle on a play at the plate in the ninth inning against the Nationals. ... RHP Zack Greinke (14-3) will take the mound for the Dodgers against LHP Patrick Corbin (14-6) and the Diamondbacks in the second game of the three-game set.
