Seattle will host the All-Stars for the third time. The ballpark, then known as Safeco Field, opened in 1999 and was the site of the American League's 4-1 victory in 2001, part of a streak of 12 AL wins around the 7-7 tie in 2002. The game marked the final All-Star appearances of Cal Ripken Jr., who homered, and of Tony Gwynn.
The 1979 All-Star Game was at the old Kingdome and was won 7-6 by the NL.
Hall of Famers Ken Griffey Jr. and Edgar Martinez are scheduled to attend the news conference along with Mariners chairman John Stanton and president of business operations Catie Griggs.
