The air, even up there at the 5,280-foot marker on the Rooftop party deck, felt heavier Tuesday night at Coors Field. Maybe that drenching rainstorm the night before, which delayed a Rockies loss before the eighth inning, lingered around LoDo.

Or maybe in the midst of a sinking season with just three victories in three weeks, the threat of another was weighing down the atmosphere.

The Rockies are hitting like their bats are bricks.

But one hitter, on one big hit in the third inning, broke through. Charlie Blackmon, one of two Rockies all-stars, hit a high, deep home run to right field, pushing Colorado to a 2-1 victory over the San Diego Padres. It was Blackmon's first home run since June 16.

"We knew it was going to be tough to score against (Tyson) Ross," Rockies manager Walt Weiss said. "But Charlie Blackmon had the big blow."

Blackmon, who Sunday became a surprise selection to the NL all-star team, leads baseball with 13 leadoff home runs and 45 RBIs from the first spot. He's the Rockies' first all-star leadoff hitter since Eric Young in 1996.

Blackmon's two-run, line drive homer, off an 88 mph slider from San Diego's Tyson Ross, scored DJ LaMahieu and gave the Rockies a 2-0 lead in the third inning.
