CREATE TABLE table_21222 ("Province" CLOB, "Skip" CLOB, "W" FLOAT, "L" FLOAT, "PF" FLOAT, "PA" FLOAT, "Ends Won" FLOAT, "Ends Lost" FLOAT, "Blank Ends" FLOAT, "Stolen Ends" FLOAT, "Shot Pct." FLOAT)

When the skip is Glenn Howard, what the minimum PF?
SELECT MIN("PF") FROM table_21222 WHERE "Skip" = 'Glenn Howard'
SELECT MIN("PF") FROM "table_21222" WHERE "Skip" = 'Glenn Howard'
