Astros' Dallas Keuchel and Cubs' Jake Arrieta Win Cy Young Awards

Updated 9:15 p.m. ET

The Houston Astros' Dallas Keuchel and Chicago Cubs' Jake Arrieta won the Cy Young Awards for best pitchers in Major League Baseball for 2015.

Keuchel received enough votes to squeak past second-place finisher David Price in the American League. Arrieta handily beat runner-up Zack Greinke in the voting for the National League.

Keuchel, who has been with the Astros for four seasons, led the American League in innings pitched with 232 and finished with a second-best earned run average of 2.48. He struck out 216 batters — good for fifth in the league.

In the National League, Arrieta finished second in innings pitched with 229 and posted a 1.77 ERA, second to Greinke, whose ERA was 1.66. Arrieta had a solid first half of the season, but he caught fire down the stretch, helping the Cubs to the playoffs for the first time since 2008. Here's a stat that speaks for itself: In his last 15 starts, Arrieta posted a minuscule 0.75 ERA.

Here's how the voting broke down, from the Baseball Writers Association of America.
