Greiner will undergo arthroscopic surgery on Thursday with Dr. Chris Mazoué with USC Sports Medicine. He will miss the 2012 Columbia Regional.

Greiner owns a .258 (24-for-93) batting average in the league with 12 of his 234 hits, extra base hits (eight doubles, one triple, three homers).

Greiner earned SEC Freshman of the Week after the Mississippi State series. It marked the second straight week a Gamecock had earned Freshman of the Week accolades.
