Colorado Rockies outfielder Charlie Blackmon just keeps reaching new heights this season, and on Saturday night, he did something that had never happened before.

Blackmon drilled a curveball from Clayton Kershaw into the Coors Field seats in the third inning. In doing so, he became the first left-handed hitter to go deep off a Kershaw curve in 2,188 1/3 innings across 332 regular-season games, according to Thomas Harding of MLB.com.

Blackmon was surprised to learn of his feat after the game.

"That's interesting. ... Are you sure?" Blackmon said. "He doesn't throw a lot of curveballs, so that's part of it. I guess it doesn't count. You've gotta do it twice, or it doesn't count."

Kershaw has thrown his curveball 13.7 percent of the time over his career and has increased his usage to 16.7 percent in 2019, according to FanGraphs.
