McClure, a center fielder, was named a second-team high school all-American and first-team all-Southeast region selection by Rawlings. He was also named to the 2012 Louisville Slugger preseason high school all-America team.
The 6-foot-3, 190-pounder hit .412 with one homer, 12 doubles, 15 RBIs, 26 steals and 28 runs scored during his senior season at Jacksonville, after leading it to the Arkansas state baseball title as a junior.
Cleveland also signed eighth-round pick Caleb Hamrick, a right-hander out of Cedar Hill High School in Texas.
Hamrick was named to the all-district team four times and was the district MVP in 2010.
The Indians were able to come to terms with Logan Vick, the team's 11th-round selection out of Baylor University. Vick hit .345 with four homers and 43 RBIs in 2012.
Cleveland signed 26 of its 40 Draft selections, including 21 of its top 24 picks and each selection from the first 10 rounds.
