With talented rookie Hyun-Jin Ryu on the mound, the visiting Dodgers go for their first series sweep of the Diamondbacks in three years Wednesday night.
A winner of three straight and 14 of 17, Los Angeles (44-45) last sat at .500 when it was 13-13 on April 30. The Dodgers are 2 1/2 games behind the Diamondbacks (47-43), who were last swept by their division rival twice during the 2010 season.
"It just gives you more confidence when you're adding it to (Clayton) Kershaw, (Zack) Greinke and Hyun-Jin, three pretty kind of top-notch guys there at the top of the rotation,'' Dodgers manager Don Mattingly said. "Then to add Ricky, if he can pitch like this, every time you go out there you think you've got a good chance to win.''
Gonzalez is batting .410 with eight RBIs during a 10-game hitting streak versus Arizona.
However, Hanley Ramirez's 19-game hitting streak ended with an 0-for-4 performance. The veteran infielder is still batting .462 in his last 21 games.
Ryu (7-3, 2.82 ERA) improved to 1-0 with a 2.21 ERA in his last three starts after he allowed two runs and four hits in 6 2-3 innings of a 10-2 win at San Francisco on Friday.
"I changed my delivery a little and the outcome was not too bad," he told the Dodgers' official website. "Everything worked out.''
Despite a 4.50 ERA, the left-hander is 1-0 in two starts against the Diamondbacks this year.
Martin Prado had an RBI and one of the five hits for Arizona, which averaged 6.4 runs and 12.0 hits while winning five in a row prior to recording the two runs and nine hits in this series.
Despite the Diamondbacks' offensive struggles, All-Star Paul Goldschmidt is 10 for 24 in the last six games. He's hit .362 against the Dodgers this season, and is 3 for 6 with a double versus Ryu.
Scheduled Arizona starter Tyler Skaggs (2-1, 3.65) looks to build on his fourth start of the season. Hours after the left-hander was recalled from Triple-A Reno, he allowed three hits in eight innings of a 5-0 victory over Colorado on Friday.
"I feel awesome,'' said Skaggs, who was sent down June 10 after he yielded five runs each in consecutive starts. "It's great. To be up here this young is a dream come true.''
Skaggs, a southern California native who turns 22 on Saturday, gave up a home run to Ramirez in five innings while not factoring in the decision of a 2-1 loss at Dodger Stadium in Sept. 1.
Facing the Dodgers for the first time since serving a 10-game suspension for his role in a bench-clearing brawl between the teams last month, Arizona's Ian Kennedy hit Ramirez in the first inning Tuesday. Los Angeles' Ronald Belisario hit Miguel Montero in the leg in the ninth but nothing resulted from either incident - at least not immediately.
"It's not over,'' Belisario said, "but it wasn't on purpose.''
