ON THE MOUND: Zack Greinke gave up one run over six innings, but that was enough to end his 15-start unbeaten streak dating to last season. His last defeat was on Aug. 9, 2014, in Milwaukee. Between then and Saturday, Greinke was 10-0 with a 1.94 earned-run average. The only run charged to Greinke came in the first inning on a solo home run by Carlos Gonzalez. That was one of four hits given up by Greinke, who struck out five, walked none and hit a batter. The Rockies blew open the game after Greinke departed, scoring six runs in the last three innings to turn a 1-0 lead into 7-0. Sergio Santos gave up five runs in two innings, surrendering a two-run home run to Daniel Descalso in the seventh inning and another to Nolan Arenado in the eighth. On the plus side, Santos managed to strike out four batters in the eighth inning, including DJ LeMahieu, who reached base on a passed ball.
