Monday night’s headliner was right-hander Antonio Senzatela on his comeback tour. But it was the Rockies’ ninth-inning rally and another terrific performance by their bullpen that brought down the house. The Rockies beat the Diamondbacks 3-2 at Coors Field on a throwing error by shortstop Geraldo Perdomo. The rally began with a leadoff single by Brenton Doyle off reliever Ryan Thompson.
