D-backs second baseman Aaron Hill, the second batter of the game, lined a ball down the left-field line that hit off the wall for what would have been a double.
Left-field umpire James Hoye, however, ruled that the ball had struck the wall to the foul side of yellow line on the padded wall.
There was no argument from Hill because he could not get a good look from 344 feet away, and with the way the visiting dugout is situated at Miller Park, none of the D-backs there could see it clearly either.
Major League Baseball does allow for video review of fair or foul home run calls, but not on whether a ball off the wall is fair or foul.
How the inning would have unfolded had the ball been ruled fair is anybody's guess. Hill stepped back in the box and promptly lined a single to center. The D-backs failed to advance him past first as Justin Upton popped out and Miguel Montero struck out.
"It is what it is," Hill said. "You know James is a great umpire and it's tough to see out there. It didn't seem like it changed anything, so who knows?"
Hill did not watch a replay of the hit after the game, but did hear about it from his teammates.
"I heard it was fair," he said. "I didn't look at it. I mean you can't go back and change it, so there's no reason to get upset about it."
A reporter jokingly told Hill that he got two hits in one at-bat.
"What was I, 4-for-3 then?" he asked.
Hill went 3-for-3 with three singles and a pair of walks.
