Former Presidents George H.W. Bush and George W. Bush will take to the baseball diamond this weekend to throw out ceremonial first pitches at the World Series.

The ex-presidents will appear at the Ballpark in Arlington on Sunday to toss out the pitches at Game 4 of Major League Baseball's championship series between the Texas Rangers and San Francisco Giants. 

The younger Bush — a former Texas governor — was part-owner of the Rangers until 1998, two years before his presidential run. 

He famously threw out a ceremonial first pitch at Game 3 of the 2001 World Series at Yankee Stadium, just over a month after the Sept. 11 terrorist attack on the World Trade Center. 

Bush again took to the mound in 2008, the last full year of his presidency, to throw out the first pitch at then-brand-new Nationals Park in southeast Washington, D.C.
