Char­lie Black­mon ripped a grand slam over the right-field fence to give the Rock­ies a dra­mat­ic 8–4 walk-off vic­to­ry over the Angels at Coors Field on Fri­day night.

“I real­ly just need­ed to not make an out and that’s it. I wasn’t real­ly try­ing to hit for extra bases or swing hard,” Black­mon said. “All wins count the same, but that’s a good time to win.”

Col­orado start­ing pitch­er Ger­man Mar­quez threw sev­en strong innings, the bullpen lost the lead but a resilient Rock­ies’ offense bat­tled back. Col­orado, after being swept in three games by the Padres this week, turned the page in a big way to start a nine-game home­s­tand, inch­ing a bit clos­er toward the eighth and final Nation­al League play­off spot at 21–23.

The Angels took a first-inning lead when Rock­ies short­stop Trevor Sto­ry unchar­ac­ter­is­ti­cal­ly made an errant throw to sec­ond on a fielder’s choice that allowed LA’s Jared Walsh to score. The Angels kept their momen­tum rolling when Justin Upton slapped a first-pitch sin­gle to left, send­ing Mike Trout home, to go up 2–0.

That’s when Mar­quez — 0–4 with a 6.00 ERA over his pre­vi­ous six starts — final­ly found his rhythm. He allowed six hits, struck out five, and didn’t allow a run over his final six innings pitched Friday.

“He didn’t have his over­pow­er­ing fast­ball that we’ve seen in the past, but it had good move­ment,” Rock­ies man­ag­er Bud Black said. “I thought the change­up, slid­er and curve all played tonight. … He gave us a good start after giv­ing up those two scratch-runs in the first and held the fort down until late in the game, which was awe­some. Very impres­sive for Ger­man. I thought he threw the ball well.”

The Rock­ies tied the game in the third. Set up by a Josh Fuentes sin­gle and Tony Wolters walk, Sto­ry blast­ed an RBI dou­ble to deep cen­ter. A Black­mon sac­ri­fice fly scored Wolters. The stale­mate extend­ed into the fifth inning when Sto­ry hit a stand-up triple off the right-field wall that brought home Ramel Tapia — giv­ing Col­orado its first lead, 3–2, which the bullpen could not hold.

The Rock­ies turned to new­ly acquired reliev­er Mychal Givens in the eighth and Daniel Bard in the ninth. Both Col­orado pitch­ers allowed solo home runs (Walsh and Antho­ny Bem­boom) as LA took a 4–3 lead into the bot­tom of the frame.

The Angels went to clos­er Ty But­trey. Rock­ies infield­er Ryan McMa­hon made him pay with a homer to left. Fuentes dou­bled and pinch-hit­ting Daniel Mur­phy got inten­tion­al­ly walked before LA pulled But­trey for south­paw Jose Qui­ja­da — who loaded the bases after four straight balls to Story.

Blackmon’s moment to shine arrived with two outs fac­ing a 3–1 count. His walk-off grand slam marked just the sec­ond in Col­orado fran­chise his­to­ry (Ryan Spilborghs, 2009 vs. Giants).

“That was real­ly great to see from Chuck,” Black said. “Let’s hope that jump­starts Char­lie and he can put more swings (togeth­er) like tonight, tomor­row, the next day, the day after that, and the next 16 games.”

The Rock­ies faces the Angels on Sat­ur­day and Sun­day to close out their three-game series.
