McCray's father Rodney got 14 big league at-bats but is more famous for crashing through the outfield fence at Triple-A Vancouver while trying to make a catch in 1991. Grant flew under the radar as a prospect until late in the spring before his athleticism started attracting clubs. The Giants signed him away from a Florida State commitment for $697,500 in the third round.
Though he has a big league heritage, McCray also spent time playing football and running track in high school, so he still has plenty of room to develop. He has a smooth left-handed swing and feel for the barrel, which bode well for his hitting ability. He has the bat speed for at least average power once he put more muscle on his lanky 6-foot-2 frame.
McCray's best tool is his plus speed, which gives him the ability to steal bases and run down balls in center field. He also has solid arm strength that allows him to play anywhere in the outfield.
