Tony Clark's drive to left nicked the foul line. That's all the Diamondbacks needed for a comeback win.
Clark's two-run, pinch-hit double highlighted a four-run eighth inning, and Arizona rallied for a 5-2 victory over the Milwaukee Brewers on Friday night.
Reliever Carlos Villanueva (1-3) was trying to protect a 2-1 lead in the top of the eighth.
He retired the first two batters, but Conor Jackson walked and took third on Mark Reynolds' single. Todd Coffey came on to face Justin Upton, who hit a slow roller in the grass down the third-base line letting Jackson score. Clark followed with his hit that replays appeared to show just catching the outside edge of the left-field line. Chris Snyder singled in Clark to make it 5-2.
"I haven't seen the replay yet," Diamondbacks manager Bob Melvin said of Clark's hit. "From what I heard, it hit the far side of the chalk. It's not my call."
The Brewers felt just the opposite.
"Clark's ball was called fair regardless of what I saw or what anybody else saw," said Coffey who allowed an inherited runner to score for the first time this season.
Brewers manager Ken Macha ran from the dugout to question third base umpire Brian Gorman and was told the ball hit the line.
"I haven't seen the replay," Macha said. "I just know by the reaction of Jason Kendall and Bill Hall who were jumping up and down."
Melvin was happy to see the Diamondbacks take advantage of some opportunities as the Brewers' bullpen failed to hold a lead. Milwaukee rallied for four runs in the seventh to beat Arizona on Thursday.
"The Justin hit was a big one for us, too," Melvin said. "We haven't been getting too many breaks. He hits a little nubber out front of third and beats it out. Tony puts a good swing on the next ball. We'll take it."
Clark added: "You can't script a full swing dribbler down the third-base line for a hit to tie the ballgame," Clark said. "That was a big at-bat."
Macha said Jackson's at-bat was key.
"It all started with a two-out walk," he said. "Walks will kill you."
Tony Pena (3-0) pitched 1 2-3 innings for the victory. Former Wolf Pack pitcher Chad Qualls worked the ninth for his fifth save in six chances.
Diamondbacks starter Jon Garland held the Brewers scoreless through six innings, striking out Ryan Braun, Prince Fielder and Mike Cameron with runners at first and second in the sixth. But the Brewers broke through in the seventh when Kendall's groundout scored Craig Counsell, who led off with a double and took third on a single by Hall.
"I'm glad that he didn't get stuck with that loss, that we came back," Melvin said. "He's pitched in that fashion for us all year. Most of the games that he's in, he's in there late in the game and they're close games. We haven't given him much run support."
Pena relieved Garland. Pinch-hitter Chris Duffy singled to left to score Hall as Milwaukee grabbed a 2-1 lead.
Milwaukee starter Manny Parra, a left-hander, dominated the eight right-handed batters in the Diamondbacks' lineup, except for switch-hitting Felipe Lopez.
Lopez, who finished with three hits, singled and went to third on Eric Byrnes' double. Parra struck out Jackson, but then walked the next two batters to force in Lopez as Arizona went ahead 1-0. Chris Young flied out to end the inning.
