AVG, OBP, SLG, ERA and WHIP are season-to-date through each game, not that game alone — so the column reads as a trend and its last value is the season figure. They stay season-to-date when the log is filtered by opponent; the figure for the filtered games is the one in the Total row. The second game of a doubleheader is marked (2).
