PHOENIX -- For the first time in almost a month, the Los Angeles Dodgers are on a winning streak, even if it's just two games.
Jeff Kent hit his 12th career grand slam and Olmedo Saenz added a two-run shot to lead the Dodgers to a 7-4 victory over the Arizona Diamondbacks on Friday night.
The Dodgers have won consecutive games for the first time since May 1, a span of 23 games.
"We're better than that," said Eric Gagne, who earned his first two saves of the season in the last two victories. "We need to show it. We need to come here tomorrow and get another one."
Arizona's Tony Clark tied the game 4-4 with a pinch-hit, two-run homer in the seventh inning. But reliever Jose Valverde (1-2) walked Milton Bradley leading off the eighth, and with one out, Saenz hit a 1-2 pitch into the Arizona bullpen in left field to put the Dodgers back in front for good.
Gagne, who missed the first 35 games because of a sprained right elbow, pitched a perfect ninth for his second save in as many nights. It was his sixth appearance, but only second save opportunity.
"I don't care if it's a save situation or not for me right now," Gagne said. "It's just a matter of getting back in shape, getting back to game situations where I need to control my body and control my emotions."
Kent's slam also went into the bullpen, a line drive just over the fence down the line on the first pitch he saw from Shawn Estes in the third inning to give Los Angeles a 4-2 lead.
Jose Cruz Jr. hit a two-run home run for the Diamondbacks.
After a tough stretch of injuries, the Dodgers have gotten consecutive strong outings from starters Brad Penney and Derek Lowe, and they have Gagne approaching his old form.
"We finally, almost 50 games into the season, have those pieces in place," manager Jim Tracy said.
With the Dodgers leading 4-2 and two outs in the seventh inning, Koyie Hill singled, and Los Angeles manager Jim Tracy lifted Lowe. Left-hander Kelly Wunsch came in to force Clark, a switch hitter, to hit from the right side. On Wunsch's first pitch, Clark homered into the left field seats to tie it at 4-4.
Tracy explained the decision to remove Lowe.
"We got a guy out there that's pitched a terrific game. He's close to 100 pitches. He's completely saturated," Tracy said. "Tony Clark is hitting 145 points higher from the left side than he is the right side.
"He has no home runs thus far this year from the right side. He has three hits off Derek Lowe, two of which are home runs. You know, it's a move that you've got to make."
Clark has two pinch-hit home runs this season, and has 23 RBI in just 73 at-bats.
Although he gave up the tying homer and got just one out, Wunsch (1-0) got the victory.
Arizona has lost four of six after winning eight of 10.
"We went through it earlier in the year, too, and we've gone through it lately with the bullpen," manager Bob Melvin said, "and we have to find a way to tighten it up."
The Diamondbacks scored twice before the first out of the game. Craig Counsell led off with a single, then moved to third when Lowe was called for two balks. Cruz followed with a home run over the swimming pool in right-center field to make it 2-0. It was Cruz's fifth homer of the season.
Two walks by Estes set up Kent's slam. Perez led off with a single, then Cesar Izturis and Jayson Werth drew one-out walks to load the bases. Bradley flew out to left for the second out to bring up Kent, whose homer was his ninth of the season.
Both center fielders made tough catches. The Dodgers' Bradley caught one over his shoulder running toward the wall off Hill in the second. Arizona's Cruz made a diving catch of Bradley's blooper to save a run in the fourth.
The Bank One Ballpark roof was closed after eight innings because of a dust storm. ... In his last appearance in Arizona, Lowe was hit near the elbow with a line drive and had to leave the game. He took another line shot, this one from Alex Cintron, on Friday night. But it hit the pitcher in his backside and he chased the ball down and threw the batter out. ... Estes got his first career stolen base. It was the fourth by a pitcher in franchise history. ... Estes and Lowe were roommates in Seattle. ... After the game, the Dodgers optioned RHP Buddy Carlyle to Triple-A Las Vegas to make room for LHP Derek Thompson, who will start Saturday night's game.
