CREATE TABLE table_name_58 (total NUMBER, finish VARCHAR2, year_s__won VARCHAR2)

When the year won is 1981, 1987, and the finish is t46, what is the lowest total?
SELECT MIN(total) FROM table_name_58 WHERE finish = "t46" AND year_s__won = "1981, 1987"
SELECT MIN("total") FROM "table_name_58" WHERE "1981, 1987" = "year_s__won" AND "finish" = "t46"
