     _a_t_b_a_t_8_6 times at Bat: number of official plate appearances by a
          hitter.  It counts as an official at-bat as long as the
          batter does not walk, sacrifice, get hit by a pitch or reach
          base due to catcher's interference.

     _h_i_t_s_8_6 hits.

     _h_o_m_e_r_8_6 home runs.

     _r_u_n_s_8_6 the number of runs scored by a player.  A run is scored by
          an offensive player who advances from batter to runner and
          touches first, second, third and home base in that order
          without being put out. 

     _r_b_i_8_6 Runs Batted In: A hitter earns a run batted in when he
          drives in a run via a hit, walk, sacrifice (bunt or fly)
          fielder's choice, hit-batsman or on an error (when the
          official scorer rules that the run would have scored anyway).

     _w_a_l_k_s_8_6 A "walk" (or "base on balls") is an award of first base
          granted to a batter who receives four pitches outside the
          strike zone.

          necessarily consecutive.
