SEATTLE – A group of students helping make an anti-bullying video at Safeco Field on Thursday were surprised by Mariners ace pitcher Felix Hernandez and Seattle rapper Macklemore.

The students from Highland Middle School in Bellevue thought they were making the public service announcement with the Mariner Moose.

But after the Moose “flubbed” his lines a couple of times, Hernandez came on in relief. Then the group was joined by Macklemore at home plate to complete the video.

The anti-bullying message will be available for radio and television use.
