                     behind Home Plate (ND indicates the number of games 
                     that were suspended and/or completed at a later date)

AVER TOT RUNS      Average Total Runs Scored in Umpire's games

H&W Per INN        Baserunners Allowed Per Inning by Starting Pitchers
                    in Umpire's games

ERA                 Overall ERA of Starting Pitchers in Umpire's games

K/BB RATE          Ratio of Strikeouts to Walks for the Starting Pitchers
                    games umpired.  The theory is that OVER Umpires tend to
                    have lower K/BB Ratio while Under Umpires tend to call
                    more strikes and thus have higher K/BB Ratios.

BB/9 INN           Average number of walks per 9 Innings pitched by a
                    Starting Pitcher in games umpired by this Umpire.  An
                    OVER Umpire tends to call more balls resulting in more
                    Walks while an UNDER Umpire tends to call more strikes
                    and fewer walks.
