Chacín was called up directly to the majors from the Class AA Tulsa Drillers on July 24, 2009. In 2010, in his first full season in MLB with the Rockies Jhoulys Chacín had nine wins, 3.28 ERA, and led all NL rookies in strikeouts with 138.
Chacín started the 2011 season as one of the best young pitchers in baseball, but after the second half of the season, he became inconsistent with his mechanics. He did, however, finish with a record of 11–14 with a 3.62 ERA in 31 starts. In 194 innings pitched, he struck out 150. However, he led the National League in walks with 87. He threw his first career shutout in his first career complete game on April 15, 2011.
In 2012, Chacín was limited to just 14 starts due to a pectoral injury.
In 2013, Chacín rebounded to give the Rockies a much needed lift in the rotation. He finished 14-10 with 3.47 ERA in 197.1 innings pitched. He kept the ball in the ballpark, allowing 11 home runs, 6 of which were allowed in Coors Field.
Chacín began the 2014 season on the DL with shoulder inflammation.
Jhoulys and former Houston Astros pitcher Gustavo Chacín are second cousins.
