ATLANTA -- Paul Goldschmidt doesn't often stand and stare at his homers. This time he had to look, just to make sure his drive stayed fair.
He liked what he saw.
Goldschmidt ripped an inside pitch from Alex Wood toward the left-field seats in the third inning. He said he immediately figured it had home run distance. He was just hoping the ball would stay fair, and it hit the foul pole for his 16th homer.
"I wasn't sure," Goldschmidt said. "I knew it probably had the distance but it started fair and was going, so that was one of the few times I was watching to see what was going to happen. I saw it hit the pole and come down. I was pretty happy."
Miley (4-6) allowed one run on five hits and one walk in 6 2-3 innings. He struck out eight. The left-hander was 0-3 in his previous nine starts and had not won since beating the White Sox on May 10. The win snapped his streak of five straight no-decisions.
Miley shrugged when asked if he was relieved to finally get his fourth win.
"You really can't control that," he said. "You've just got to go out and try to give your team a chance to win. That's the plan. You don't go out to try to get wins, you just try to get quality innings and get your offense on the field and we were able to do that and able to score enough runs today."
Wood (6-7) allowed two runs on only three hits and three walks in seven innings.
B.J. Upton was 0 for 4 with three strikeouts to end his career-best 11-game hitting streak for NL East-leading Atlanta. The loss kept the Braves from sweeping their third straight series.
"We had a great run, had a great homestand," manager Fredi Gonzalez said.
Arizona right-hander Brad Ziegler gave up a leadoff single to Andrelton Simmons in the eighth. With one out, Ziegler walked Justin Upton, and the runners advanced on Jason Heyward's groundout. Ziegler struck out Chris Johnson to end the inning.
Walks hurt both starting pitchers.
Wood issued a walk to Miley to open the third inning before Goldschmidt's two-out homer gave the Diamondbacks a 2-0 lead. Goldschmidt, who had an infield single in the first, had two of Arizona's three hits off Wood.
"That's baseball for you," Wood said. "You go into the game telling yourself that there's one guy you don't want to let beat you and then he ends up beating you."
Miley walked Justin Upton to open the fourth. He scored from second on Johnson's single up the middle.
