Charlie Blackmon hit a tiebreaking, two-run homer off Madison Bumgarner in a four-run sixth inning, left fielder Raimel Tapia made a dazzling catch to thwart a rally attempt and the Colorado Rockies beat the Arizona Diamondbacks 7-6 on Saturday. Bumgarner (4-4), limited to four innings on Monday against the Los Angeles Dodgers because of soreness in his midsection, allowed seven runs — five earned — and eight hits in six innings as his ERA rose to 4.53. The Rockies won their second straight game after a five-game skid.
