Table schema:
CREATE TABLE table_name_89 (top_5 INTEGER, events VARCHAR, cuts_made VARCHAR, tournament VARCHAR)

Question: What is the average value for Top-5, when the value Cuts is 5, and when the tournament is the Open Championship, and when the value Events is less than 6?
SQL: SELECT AVG(top_5) FROM table_name_89 WHERE cuts_made = 5 AND tournament = "the open championship" AND events < 6
