Pearl Jam guitarist Mike McCready will be making another appearance at Safeco Field in Seattle to perform "The Star-Spangled Banner" when the Mariners take on the Chicago White Sox on August 8.

The Mariners are releasing a special section of tickets that will help raise funds for the Crohn's and Colitis Foundation of America. If you order tickets from the Mariners site, you'll also get a set of unique guitar picks.
