PHOENIX -- The D-backs are one victory away from winning their first series at home this season.
The Dodgers are one win from claiming another series in their domination of a division rival in head-to-head competition.
Sunday's rubber match at Chase Field definitely means something.
The Dodgers, who are 8-2 against the D-backs this season and 14-8 on the road, will send Dan Haren to the mound in the series finale. The D-backs counter with Josh Collmenter.
"It may have felt like it's been one-sided this whole year, but that's a team with a lot of pride and plays the game really hard," Dodgers catcher A.J. Ellis said. "They are not going anywhere."
Collmenter battled his way through five innings in his last start against the Nationals. He didn't have his best command, and the Nats made him pay for it with a series of extra-base hits that led to a no-decision. The right-hander is 1-2 with a 4.28 ERA in six starts since moving from the bullpen to the rotation.
"[He] struggled through five, and didn't have much of changeup, and they pounded three of them," D-backs manager Kirk Gibson said after Collmenter's last start. "[Denard] Span got a triple, and two home runs on the other ones."
As for Haren, he went seven innings, allowing three earned runs, to beat the Marlins on Monday. He won against the D-backs on April 13 in his only start against them this season.
"Typical Dan," Mattingly said after Monday's win. "He stays in the game, keeps making pitches and kind of hangs in there."
Haren has limited opponents to three or fewer runs in 12 consecutive starts, but he'll be challenged by D-backs first baseman Paul Goldschmidt. On Saturday, Goldschmidt scored a club-record five runs and racked up a career-high six RBIs in an 18-7 D-backs victory.
"It was a good game, but we need to go out there and try to have some good at-bats tomorrow and the days after that," Goldschmidt said.
Dodgers: Ryu closing in on return
Left-hander Hyun-Jin Ryu continues to make progress and remains on track to come off the disabled list next week.
He threw a simulated game Friday and was scheduled to play catch on Saturday. He has showed no signs of the left shoulder-blade soreness that put him on the disabled list after an April 27 start.
"We feel pretty good about where he is at," Mattingly said. "We just want this throwing to go good."
Ryu could start against the Mets in New York next Wednesday or make a Minor League rehab start.
D-backs: Hall of Famer on board
Tony La Russa, named the team's chief baseball officer Saturday, is getting right to work.
La Russa plans to visit each of the team's Minor League affiliates before joining the big league team on the coming road trip.
"He said I'd like to see every player in the system," team president and CEO Derrick Hall said. "He said, 'I have a pretty good idea what we have in the system, I have a pretty good idea of what we have going on here, now I want to see what we have below.'"
La Russa had been serving as special assistant to Commissioner Bud Selig and was a member of the Commissioner's 14-member special committee for on-field matters since December 2009. He was elected to the National Baseball Hall of Fame over the winter and will be inducted in July.
• Arizona second baseman Aaron Hill was scratched from Saturday's game with a sore shoulder.
• Collmenter is 2-3 with a 6.00 ERA in 13 career games against the Dodgers.
• Yasiel Puig is riding a 16-game hitting streak and has at least one extra-base hit and one RBI in a Dodgers-record eight consecutive games.
• The D-backs recorded three triples in an inning for the first time in club history Saturday against Clayton Kershaw in the second.
