Yes sir, you can declare multi-column primary keys. After the column 
definitions, type
    PRIMARY KEY (<column list>)
This is covered in the online manual.

If you want to use an auto_increment field as the primary key, you 
can insure uniqueness in the SportName and TeamName fields by 
declaring a UNIQUE INDEX in the same way.
