The San Francisco Giants and Colorado Rockies played a doubleheader on Tuesday that featured big, decisive innings on offense- for each team.

In Game 1, the Giants scored *10* runs in the first inning. First baseman Brandon Belt had five RBI in the inning, capped off with this grand slam:

And Buster Posey — who looks back to prime, MVP level form with an insane .382/.440/.735 slash line — cranked his seventh dinger of the season to give the Giants their 10th run of the inning.

The Giants came away with a 12-4 victory in the seven-inning game.

In the nightcap, the Giants were ready to complete the doubleheader sweep, and then #Coors happened in the bottom of the seventh.

The Giants took a 6-2 lead into the bottom of the seventh, and it remained that score with two outs. But the Rockies erupted for six runs and walked it off on a Charlie Blackmon three-run blast:

So the Rockies scored six runs with two outs in the final inning to get a walk-off victory, hours after allowing a 10-run inning that led the Giants to victory.

That’s Coors Field for ya (and why pitchers hate it).
