The Seattle Mariners say a pre-recorded announcement that requested fans to evacuate Safeco Field before Thursday's Mariners-Angels game was a mistake.
About two hours before the 7:10 p.m. game time, a technician pressed the wrong button and the unnecessary evacuation announcement was heard. There was no follow-up to the announcement, but there were few people in the ballpark at the time.
Club officials told ushers around the park to spread the word that announcement was inadvertent and there was no need to leave.
The Mariners say 13,000 tickets were sold for Thursday night's game. The all time record low for Safeco Field was set a couple weeks ago at 10,493.
