Wood hasn't allowed a run in three of four starts, helping him post a 0.82 ERA. Wood has struck out 25 and walked four in 22 innings, while posting a .182 opponents' batting average.

The 2012 second-round pick is considered the Braves' sixth-best prospect by MLB.com.

"He's got a little funk in his delivery, which I think helps him," Braves general Wren told MLB.com in March. "The good thing is there are guys who have funk who can't repeat. He repeats his delivery and throws quality strikes, along with having good quality stuff. He's got good life and a good breaking ball. Depending on the role as he moves forward, he's another guy you watch over the next year or so to determine what is the ideal role. You know at the very least he can be a quality left-handed reliever that throws real hard."

Wood, who is considered a top 10 prospect in the Braves' system by Baseball America (seventh) and MLB.com (sixth), went 4-3 with a 2.22 ERA and 1.01 WHIP in 13 starts for Class A Rome last season. He was a second-round draft pick in 2012.
