LOS ANGELES (AP) The Dodgers mustered just one hit off Zack Greinke through three innings. Then their former teammate faltered and Los Angeles hammered the former Cy Young Award winner for five home runs.
Joc Pederson joined the 20-plus home run club with a solo shot and Los Angeles beat Greinke and the Arizona Diamondbacks 10-2 on Monday night in his first road start against his former team.
''Things were going bad and they were swinging good,'' Greinke said.
The Dodgers increased their lead in the NL West to a season-high four games over San Francisco, which lost 6-0 at Colorado. They have won three straight and four of five.
''They're not going to quit, so you can't take your foot off the gas,'' Dodgers rookie shortstop Corey Seager said.
Kenta Maeda (14-8) allowed one run and three hits in 6 1/3 innings, struck out eight and walked one to tie Kazuhisa Ishii and Hyun-Jin Ryu for the second-most wins by a Los Angeles rookie, trailing only Rick Sutcliffe's 17 in 1979. The Japanese right-hander has won six of his last seven.
''He was staying out of the middle of the plate and he was getting strikes from both sides and hitting his spots,'' said Arizona's Paul Goldschmidt, who was 0 for 3 with a walk and a strikeout. ''He really had command of all four pitches.''
Greinke (12-5) imploded in his return to Dodger Stadium for the first time since spurning the team as a free agent last December.
He signed a $206.5 million, six-year deal in the desert after winning 51 games and compiling a 2.30 ERA from 2013-15 as part of a 1-2 punch with ace Clayton Kershaw in Los Angeles.
Greinke gave up eight runs - second-most this season - and nine hits in 4 2/3 innings and struck out six. The five homers - four in the fifth inning - were a career-worst. He hadn't allowed a homer in his last three starts.
''I felt real comfortable out there, just not a good game,'' he said. ''I felt like I was going to make pitches and get every guy out.''
Adrian Gonzalez broke open a scoreless game with a two-run shot in the fourth, a preview of what was to come.
''More times than not you are going to get him out with that pitch,'' Greinke said, ''but he is one of those guys that can actually get to it, so I wasn't completely shocked.''
After Howie Kendrick grounded out to open the fifth, Greinke gave up five consecutive hits. Pederson's homer was his sixth in as many games against Arizona. He, along with Justin Turner (25), Yasmani Grandal (24) and Seager (24) give the Dodgers four or more players with 20 or more homers for the seventh time in franchise history.
''Zack is one of the best pitchers in the game,'' Pederson said. ''We were really able to break it open and that's tough to do against a pitcher like him.''
Greinke called the 1-2 pitch to Pederson ''probably the worst pitch of the night.''
Two hitters later, Seager slammed a three-run homer into the pavilion in left field. Turner followed with a solo shot in nearly the same location as fans directed a derogatory chant at Greinke, who was booed heartily in his first at-bat.
With two outs, Grandal homered for the third straight game to right field, making it 8-0. Arizona manager Chip Hale came out to pull Greinke, who walked off with his head down and boos ringing in his ears.
''He's so strategic with everything he throws,'' Seager said. ''So it's fun to kind of play with him. You know everything he does is with purpose.''
Last season, Greinke led the majors with a 1.66 ERA, won a career-high 19 games and was an NL All-Star while helping the Dodgers win a third straight division title. Now, they are in pursuit of a fourth, while the D-backs have failed to contend this season and are mired in next-to-last place.
Jake Lamb's RBI single and Chris Owings' RBI double accounted for Arizona's runs.
GONZO VS D-BACKS
Gonzalez's 35th career homer against the D-backs ties Todd Helton for second-most all-time against the franchise, trailing only Barry Bonds' 39.
GREINKE AT THE RAVINE
Until Monday, Greinke had been dominant at Chavez Ravine, winning his previous eight starts and compiling a 1.09 ERA dating to July 4, 2015. He was one of five pitchers to win eight-plus consecutive starts there, the longest active streak in the majors at a single ballpark. The right-hander had limited the opposition to two or fewer earned runs in 14 straight starts at the stadium. Greinke had beaten the Dodgers once this season, 3-2 on June 13 at Arizona.
ONE TRIPLE AWAY
Seager came up a triple short of hitting for the cycle. He singled in the first, doubled in the fourth and homered in the fifth before grounding out in his last two at-bats. He is hitting .342 with 12 doubles, five homers and 15 RBIs in 19 career games against Arizona.
ROOKIES ON THE MOUND
The Dodgers had four straight rookie starters from Aug. 27-31, the team's first time doing so since Sept. 8-10, 1952. The franchise was in Brooklyn then and Ken Lehman, Billy Loes, Ray Moore and Johnny Rutherford took the mound. The Dodgers are doing it again this week. Jose De Leon won his major league debut Sunday, Maeda won Monday, Ross Stripling goes Tuesday and Brock Stewart pitches Wednesday.
D-backs: LHP Andrew Chafin (shoulder, groin) will be activated Tuesday after pitching a scoreless inning last weekend for Triple-A Reno.
Dodgers: RHP Brandon McCarthy (right hip stiffness) was to make his first rehab start Monday for Class-A Rancho Cucamonga. He last pitched on Aug. 13. ... LHP Scott Kazmir (neck inflammation) will make a rehab start Wednesday for Triple-A Oklahoma City. ... LHP Alex Wood (posterior elbow impingement) will throw a bullpen session in a few days, followed by a simulated game. ... RHP Pedro Baez will rejoin the team on Tuesday now that Double-A Tulsa's season has ended.
D-backs: RHP Shelby Miller (2-10, 6.81 ERA) makes his second start in the majors since July 6. He allowed two runs in six innings of a loss at San Francisco on Aug. 31. He last faced the Dodgers on July 20, 2014, when he tossed a scoreless inning of relief as a member of the Cardinals.
Dodgers: Stripling (3-6, 4.15) is 2-4 with a 4.84 ERA in nine games (seven starts) at home. The right-hander has struck out 30 and walked 13. He has a 3.72 ERA in two games (one start) against Arizona this season, limiting the opposition to a .229 average.
