PHOENIX -- Tony Clark came through again for the Arizona Diamondbacks.
Clark, who has spent much of the season picking up the Arizona offense, broke up a scoreless game with a seventh-inning home run, and the Diamondbacks beat the Cincinnati Reds 2-0 Sunday.
After Clark's two-out solo shot, Shawn Green doubled and pinch-hitter Luis Terrero lined an RBI single into right field.
"To have Greenie follow it up with a double and then Terrero come up with a big hit to give us two runs and a little bit of breathing room was all the more important, especially against that lineup," Clark said.
The rally ended what had been a superb outing for Eric Milton, who had allowed only a pair of singles by Alex Cintron in 6 2/3 innings before Clark stepped to the plate.
Milton (4-10) gave up five hits and had a season-high eight strikeouts. He walked none.
"He pitched great," second baseman Rich Aurilia said. "If you ask him, I think he'll tell you he made one mistake, and that was to Tony Clark -- left the changeup up."
Lance Cormier, who bailed Diamondbacks starter Michael Gosling out of a jam in the sixth and worked the seventh, earned the win. Cormier (5-1), Armando Almanza, Jose Valverde and Brian Bruney combined for 3 1/3 hitless innings to finish.
Bruney struck out the side in the ninth for his 10th save in 13 chances.
"I was prepared to go early if Gos got in trouble," Arizona manager Bob Melvin said. "That's one of the reasons we didn't use Lance yesterday -- we wanted to give him potentially more than one (inning), Valverde more than one. Really, all I needed was four from Gos and keep us in the game.
"But 5 2/3 and no runs? It was tough to take him out."
The Reds had taken the first two games of the series aided by late home runs -- Ken Griffey Jr. hit a tying three-run shot on Friday and Adam Dunn hit a grand slam Saturday.
This time, Clark, a part-time first baseman, drove his 13th into the left-field seats.
Cintron singled on Milton's first pitch, but the left-hander, who won at San Francisco on Tuesday for his first victory in seven starts since May 23, struck out the next two hitters and retired the next 17.
Milton matched his previous season high for strikeouts when he got defensive replacement Quinton McCracken swinging for the second out of the sixth.
It was a big out, because Cintron singled again. Royce Clayton, the next batter, hit a dribbler along the first base line, and the inning ended when he was called out for going too far outside the line trying to dodge Sean Casey's tag.
Gosling gave up a leadoff hit in four of the first five innings, but also got two outs on groundballs in each frame to keep it scoreless.
In the fifth, Wily Mo Pena singled and Jason LaRue walked with nobody out, but Gosling fielded Milton's bunt and forced Pena at third. Then Troy Glaus made an unassisted force at third after a grounder by Felipe Lopez, and Rich Aurilia popped up to center field.
"You're not going to win a lot of games if you don't hit the ball with guys in scoring position," Reds manager Jerry Narron said.
Gosling, who gave up five hits and four walks in 5 2/3 innings, left after Joe Randa's two-out double and a walk to Dunn. Cormier walked Pena to load the bases, but LaRue flied out.
"I was mad at myself for not finishing that sixth inning," Gosling said. "I shouldn't have made Cormier come in there. But, he did and he did a great job."
The Diamondbacks turned double plays to end the first and second innings. Casey grounded into his major league-high 21st with a tapper back to Gosling, and Pena hit into a 6-4-3. ... Casey went 0-for-3 to end a five-game hitting streak. ... Milton's major league-high 29 homers allowed are the most by a Reds left-hander since Tom Browning gave up 32 in 1991. RHP Jose Acevedo gave up a team-high 30 last year. ... Gosling and Kimberly Sandler of San Diego will be married on Tuesday. He said Brandon Webb, another member of the rotation, and former Arizona pitchers Andrew Good and Chris Capuano are part of the wedding party.
