Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###

### Question ###
What is the lowest Long, when Name is Kass, Rob, and when Avg/g is less than -0.30000000000000004?

SELECT MIN(long) FROM table_name_81 WHERE name = "kass, rob" AND avg_g < -0.30000000000000004
