Hmmm, Garry's BA and OPS last year in 11 games was 000.
Doing well against Spring Training pitching may, or may not, mean much depending on the pitcher one is facing; doing lousy against Spring Training pitching means a lot, if you can not hit against any one here you probably will be a failure in the Big Show.
A high K rate here will probably follow the batter to the regular season.
If it meant nothing , there would not be visits to the mound by coaches or batters taking a time out, as why would they if it was meaningless?
