Ole Miss assistant coach and recruiting coordinator Dan McDonnell later confirmed the signing.
The Cubs have now signed their first 14 overall picks from this year's draft, beginning with first round selection Mark Pawelek and ending with 13th round pick Brett Jackson. The Cubs received an additional third round pick courtesy of the Red Sox as compensation for losing Matt Clement, a type B free agent.
Holliman, a native of Germantown, Tenn., went 8-4 with a 3.90 ERA in 18 starts during his junior season at Ole Miss. He is the most recent 2005 draft pick to sign, followed by shortstop Dylan Johnston--the organization's fourth round pick from Hamilton High School in Chandler, Ariz.
Overall, the Cubs have now signed 29 of their 51 picks from this year's draft.
