Arrieta, Keuchel ace Cy Young awards

Chicago Cubs right-hander Jake Arrieta won a tight race to become the National League Cy Young winner on Wednesday, while lefty Dallas Keuchel of the Houston Astros earned the vote as the American League's top pitcher.

Arrieta, 29, edged out Los Angeles Dodgers teammates Clayton Kershaw and Zack Greinke for the coveted award after going a league-best 22-6 and posting a 1.77 ERA that was second only to Greinke (1.66).

The ultra-consistent Keu-chel went 20-8 with three complete games and a 2.48 ERA in 33 starts. He led all AL pitchers in wins and innings pitched (232) to gain the nod over 2012 winner David Price of the Toronto Blue Jays, by 186 points to 143.
