Arizona Diamondbacks manager Kirk Gibson moved Miguel Montero down to eighth in the lineup, hoping it would give him a spark, playing a hunch that he might come up in a big situation. He was right on both counts. Hitting before the pitcher for the first time in two years, Montero hit a tiebreaking homer off the right foul pole in the eighth inning, helping the Diamondbacks beat the Philadelphia Phillies 3-2 Friday night for their fifth straight victory.
