CREATE TABLE table_name_20 (goals_for INT, goal_difference VARCHAR, goals_against VARCHAR)

What is the fewest goals for when goal difference is +10 and goals against is more than 61?
SELECT MIN(goals_for) FROM table_name_20 WHERE goal_difference = "+10" AND goals_against > 61
SELECT MIN("goals_for") FROM "table_name_20" WHERE "+10" = "goal_difference" AND "goals_against" > 61
