text: what's whip? baseball walks and hits per inning pitch.  this is more or less the number of baserunners a pitcher allows an inning... this is also considered a more accurate representation of how good a pitcher is (much more so than era).  a excellent whip is 1.00 or under; usually only the top closers and maybe one or two starters have whips this low.  a whip of 1.50 i'd think would be average, anything above that is... not very good.
