Barker was drafted by his hometown Atlanta Braves in the 16th round, with the 493rd overall pick.
As a senior at Mercer, Barker went 4-4 in 15 starts, finished with a 3.84 ERA and a team-high 63 strikeouts over 68 innings.
A right-hander who graduated from Etowah in 2010, Barker started as a true freshman for the Bears, progressing from a mid-week starter into a weekend starter, making 20 appearances over the course of the season. He finished with a 4-0 record and a 3.38 ERA.
Barker was named to the Atlantic Sun Conference’s all-freshman team that year.
As a sophomore, Barker proved his value to Mercer once more, splitting time as a starter and closer. He made 22 appearances — including 12 starts — and finished with a 5-5 record and 3.47 ERA.
As a junior, Barker served as the Friday night starter and had a career year on the mound, starting 17 games and finishing with a 7-2 record. He was third in the A-Sun with 79 strikeouts and sixth with an ERA of 2.66.
Barker finished his junior season by being named the A-Sun’s Scholar-Athlete of the Year and to the all-conference second team.
Should Barker come to terms with the Braves, he would likely start out with the team’s rookie-level affiliate in Danville, Va., or in the Gulf Coast League at the team’s complex in Kissimmee, Fla.
Barker was one of two Mercer players drafted Saturday, joining third baseman Chesny Young, a 14th-round pick of the Chicago Cubs.
