Talk about strange plays, and heads up thinking.
It happened in the seventh inning with Arizona already leading 4-1. Peralta was the runner on third base after tripling earlier in the inning and Miguel Montero was at first after a walk. On the mound for Colorado was Rex Brothers and behind the plate was Michael McKenry. After Brothers delivered an 0-2 pitch outside to Jordan Pacheco, McKenry very casually lobbed the baseball back to Brothers, which many Diamondbacks players and coaches noticed he had a tendency to do.
In fact, McKenry's lobs had become a topic of conversation in the Arizona's dugout, and veteran teammate Cliff Pennington had planted the seed in Peralta's mind that he should take off if it happened with him on base. So as soon as Peralta saw McKenry lean back and lob it, he immediately took off for home. There was no hesitation whatsoever, and thanks to a bobble by Brothers, he recorded Arizona's first steal of home since Chris Young in 2007.
