Table schema:
CREATE TABLE table_name_52 (lost VARCHAR, club VARCHAR, played VARCHAR, losing_bp VARCHAR)

Question: What is the total number of games lost when 22 have been played, the losing BP number is 2, and the club is Merthyr RFC?
SQL: SELECT lost FROM table_name_52 WHERE played = "22" AND losing_bp = "2" AND club = "merthyr rfc"
