The Dodgers will look to get back to .500 for the first time since the end of April when they go for a three-game sweep of the D-backs on Wednesday night at Chase Field.
The Dodgers have won three straight games and 14 of their past 17. More importantly, they have won 11 of their last 13 games against National League West opponents. The recent surge has brought Los Angeles within 2 1/2 games of first-place Arizona. The Dodgers were 9 1/2 games out of first place nearly three weeks ago.
"Without this streak, who knows what position we'd be in," said Dodgers catcher A.J. Ellis. "The other teams in the NL West have come back to us. Early on, every other team in the division had a hot streak except us. Then it just so happens they all had a cold streak and we got hot and within striking distance."
The Dodgers won the first two games of the series behind strong pitching performances from Zack Greinke and Ricky Nolasco, acquired in a trade with the Marlins over the weekend. Rookie Hyun-Jin Ryu will look to continue the trend when he faces Arizona for the third time this year.
The D-backs, meanwhile, are 5-5 over their past 10 games. Arizona has nine hits in the series, compared to 27 for L.A.
Tyler Skaggs will face the task of cooling off the Dodgers in only his fifth start this season. The left-hander was promoted from Triple-A on Friday, and responded with eight scoreless innings to beat the Rockies. That performance earned Skaggs a second start in place of the injured Trevor Cahill.
"He pitched great. I'm not going to take him out of there now," said D-backs manager Kirk Gibson. "He's certainly developing, but he was good. He's only 21 years old, so you hope he starts to benefit from the experience."
Skaggs, who will turn 22 on Saturday, was born in Woodland Hills, Calif., and graduated from Santa Monica High School in 2009. In his only other start against his hometown club, Skaggs settled for a no-decision at Dodger Stadium in September.
Dodgers: Lilly seeks bullpen role
Left-hander Ted Lilly, on the disabled list for the third time this season, wants a shot as a reliever.
Lilly told club officials Tuesday he would like to pitch out of the bullpen when he's activated. The veteran hasn't made a relief appearance since 2003, but said he can't manage a chronic neck issue as a starting pitcher.
"Ideally, I'd like to be a starter and be effective in that role," Lilly said Tuesday. "I've had a hard time staying healthy. I pitched Saturday [rehab start at Class A Rancho Cucamonga], and it was sore Sunday. Yesterday, it was pretty good."
Dodgers manager Don Mattingly said the club will "give it a shot" and have Lilly pitch simulated games every other day to evaluate him as a reliever.
Lilly is 0-2 with a 5.09 ERA in five starts this season.
D-backs: Eaton activated; Brewer optioned
Outfielder Adam Eaton came off the 15-day disabled list on Tuesday and reliever Charles Brewer was optioned to Triple-A Reno.
Eaton hit leadoff and started in center field in his first Major League game since September. But he made a costly error in the fifth inning that allowed two runs to score.
Eaton hit .256 with five doubles, two home runs, 13 RBIs and eight stolen bases in 26 Minor League games. He strained his left elbow during Spring Training, and then suffered a setback during his rehab, which caused him to miss over three months.
Brewer, 25, appeared in four games with the D-backs, allowing two earned runs in six innings.
• Dodgers outfielder Carl Crawford scored two runs and had a bunt single in the fifth inning on Tuesday, his first hit since coming off the DL on Friday.
• The D-backs are 6-3 in their past nine games against the Dodgers, and 19-10 since the start of 2012.
