Baseball fans spooked by 'Thriller' flash mob

Baseball fans came in for a spooky surprise after a flash mob ran onto the pitch and performed a set to Michael Jackson's Thriller.

The diverse dancers wore all sorts of costumes from zombies to sumo wrestlers, to former US president Abraham Lincoln.

The performance was part of the San Diego University baseball team’s annual Halloween Game.

Coach Mark Martinez told the San Diego Union Tribune newspaper that the “Thriller” dance was a tribute to the team's former manager Tony Gwynn, a fan of Jackson’s music, who died last year.
