South Atlantic League hitter can rejoice, as the Rockies promoted arguably the league’s best pitcher to high Class A Modesto.

Asheville righthander Jhoulys Chacin–who says his name is pronounced "YO-liss"–will join Modesto for the second half of the season after posting a 1.86 ERA in 111 1/3 innings. Chacin, 20, has three pitches that most scouts say grade out as at least average, including a two-seam fastball that has helped him generate a well-above-average 2.83-to-1 groundout-to-air out ratio. His fastball generally sits in the low-90s, but he has touched 95 mph.

When the Rockies signed Chacin out of Venezuela in 2004, he started off throwing a four-seam fastball, but he eventaully picked up the two-seamer.

"I mostly use it go get groundballs and double plays," Chacin said through an interpreter last week at the SAL All-Star game, where he was the starting pitcher for the Southern Division. "I just focus on keeping the ball low and not giving hitters pitches to drive."

Chacin also has a high-70s curve with late break and a good changeup. Chacin did not have a changeup when the Rockies, but it has developed into his best secondary pitch.

"In a tough situation, I’m more likely to throw a changeup than a curveball," Chacin said. "The changeup is my go-to pitch."
