This past season, Greiner helped lead the South Carolina Gamecocks to the NCAA regionals by batting .311, with a .389 on-base percentage and a .486 slugging percentage. He's improved each year offensively while at the University of South Carolina and he's considered to have some potential raw power at the catcher position.
At 6'5" he's tall for a catcher, but that hasn't stopped scouts from raving about his excellent defense behind the plate. He features a canon for an arm, the agility to block balls in the dirt and he is plus at receiving pitches behind the plate.
He joins fellow SEC college baseball player Spencer Turnball from Alabama and Derek Hill a high schooler out of California as one of the Tigers draft picks in this years MLB Draft. The Tigers farm system is considered one of the worst farm systems in Major League Baseball. If Greiner performs he could rise fairly quickly through the system to take center stage on a World Series contending team.
