Rockies closer Greg Holland struck out two in a perfect ninth inning for his 27th save, which is a new club record for most before the All-Star break.
The Reds didn't go quietly, though. Trailing 3-1 in the top of the sixth, Scooter Gennett and Joey Votto launched back-to-back solo home runs to lead off the frame. Their efforts were undone in the bottom half of the inning by Tapia's homer, though.
MOMENTS THAT MATTERED
Milestone jacks: Rockies starter Jeff Hoffman, who allowed three runs over seven innings, had been cruising for much of the game, but Gennett and Votto's home runs tied it up quickly.
