Replay overturns Parra's homer

Umpires award D-backs outfielder RBI double vs. Giants

PHOENIX -- D-backs outfielder Gerardo Parra had a two-run homer overturned thanks to the use of video replay in the third inning Tuesday night at Chase Field.

With Miguel Montero on first, Parra drove a Matt Cain ball deep to right-center. First-base umpire Marty Foster initially called the ball a home run. Before Giants manager Bruce Bochy could argue, the umpires quickly huddled and decided to review the play.

The replay system at Chase Field is located to the first-base side of home plate near the umpires' dressing room.

After a delay of only several minutes, the umpires emerged and ruled the ball a double. Montero was allowed to come around to score because the umpires ruled that he would have scored had the ball been ruled a double from the start, giving the D-backs a two-run lead in an eventual 10-8 victory.

Replays showed that the ball struck the green padding halfway up the outfield wall rather than clearing the wall.

D-backs manager A.J. Hinch briefly discussed the call with home-plate umpire Wally Bell.

"They got it right," Hinch said. "I just wanted to make sure the run was going to score on their discretion."

Parra wound up scoring anyway on a single to left by Brandon Allen.
