The D-backs and Dodgers have both struggled against the National League West early in 2013.
Arizona is 9-10 against the division, while the Dodgers have a 5-13 mark vs. the rest of the NL West.
The division rivals will meet for the first time this year at Dodger Stadium on Monday in the opener of a three-game series, each looking to break out of a recent slump.
The D-backs have lost five of their last six games and are 7-9 during a 16-game stretch against division opponents that continues Monday night in Los Angeles.
The Dodgers have sustained a rash of injuries of late and lost six of their last eight. Despite losing shortstop Hanley Ramirez to the disabled list Friday and second baseman Mark Ellis nursing a strained right quad for more than a week, Dodgers manager Don Mattingly said his club still has enough to be competitive.
"For the most part, we haven't been consistent enough," Mattingly said. "We get a lot of hits, but aren't getting them in. I don't think injuries are that big a factor. Every club's got guys missing.
"We can still win. We're capable and we know it. Because we're down a guy or two doesn't mean we can't compete. We can't feel sorry for ourselves."
Trevor Cahill will start for the D-backs on Monday. The right-hander has pitched better than his 1-3 record suggests. He owns a 2.84 ERA and has gone at least seven innings in three of his last four outings. Cahill allowed one run in eight innings against the Giants on Tuesday, but settled for a no-decision.
Cahill tossed eight scoreless innings in that outing, but allowed a single to the leadoff hitter in the ninth and was removed from the game. Pablo Sandoval homered off closer J.J. Putz two batters later to give the Giants a 2-1 victory.
"It's real frustrating when you're so close and you can't finish it out," Cahill said. "You're going to kick yourself maybe even more than if I'd only gone three innings and given up 10. It's a bad feeling."
The Dodgers are expected to activate Chris Capuano off the disabled list before Monday's game to start against the D-backs. The left-hander is returning from a strained left calf that he suffered in his start against the Padres on April 16. Capuano made one rehab start Wednesday with Triple-A Albuquerque, allowing two runs in 5 1/3 innings.
D-backs: Sax returns to L.A.
Steve Sax makes his first visit as a coach to Dodger Stadium, where he played for eight seasons from 1981-88. The D-backs first-base coach was drafted by the Dodgers in 1978 and won the NL Rookie of the Year Award with the club in 1982.
Sax will be glad to visit some old friends, but said he's "looking forward to us hopefully beating those guys."
"It's amazing how many guys stay intact," Sax said. "Last time we went to L.A., the same guys are doing the escalators, the same guys are doing the elevators, the same people work in the food area. It's funny how that stays the same. I think it's a great park still, and I think it's better now that the amenities have been fixed up and it's been brought up to date. I think it's a great place to watch a game and I have a lot of good memories there."
Sax is in his first season as a coach with the D-backs.
Dodgers: Gonzalez dealing with neck issue
Adrian Gonzalez was out of the lineup for a third straight game Sunday against the Giants, the result of a stiff left trapezius muscle at the base of the neck, but he entered the game later as a pinch-hitter and singled in two runs.
Gonzalez sustained the injury in a collision with first-base umpire Tony Randazzo on Wednesday night against the Rockies when the slugger turned to chase a double down the line by Carlos Gonzalez.
Gonzalez leads the Dodgers with 22 RBIs and is hitting .337 with three homers in 28 games.
• Dodgers catcher A.J. Ellis is 6-for-14 (.429) in his career against Cahill with a solo homer.
• D-backs first baseman Paul Goldschmidt is 9-for-12 (.750) in his career against Capuano with two homers, three doubles and seven RBIs.
