Table schema:
CREATE TABLE table_name_57 (points_1 INTEGER, goal_difference VARCHAR, drawn VARCHAR, goals_against VARCHAR, lost VARCHAR)

Question: What is the most points 1 when the goals against are fewer than 97, lost less than 22, 9 draws and goal difference of +28?
SQL: SELECT MAX(points_1) FROM table_name_57 WHERE goals_against < 97 AND lost < 22 AND drawn = 9 AND goal_difference = "+28"
