With the yell of "Squad change" in the 18th inning, players from both teams rotate onto-and-off the field, during the marathon baseball game at GCS Stadium in Sauget. The teams -- Joplin vs St. Louis -- are holding the 62 hour-long marathon game in an attempt to get into the Guinness World Book of Records, and also as a fundraiser to help the tornado victims of Joplin, Missouri. The game began at 5 a.m. on Friday, under the lights at GCS Stadium. The participants play in roughly four hour "shifts" and in their down-time they rest, sleep, or eat. The game should end around 7 p.m. on Sunday. The fundraising efforts underway include pledges for time played, auctions, and more, all designed to help the victims of the EF5 multiple-vortex tornado that hit Joplin on the afternoon of May 22, 2011. About a third of the town was destroyed, with damages estimated at $2.8 billion. A total of 161 people were killed, with another 1,100 people injured.
