Pitcher cards have different schema than batters: (1) double_cf instead of double_pull, (2) flyout_cf_b instead of flyout_a/flyout_bq, (3) no groundout_c, (4) xcheck_* fields for 29 fielder chances, (5) pitching block for starter/relief/closer ratings. Combined OPS formula also differs: batters use min(vL,vR), pitchers use max(vL,vR). Detection in YAML profiles via player_type field or presence of xcheck_p/double_cf in ratings.
