Ambassador Caroline Kennedy and Japanese Home Run King Sadaharu Oh toss out first pitch

U.S. Ambassador to Japan Caroline Kennedy joined Japanese Home Run King Sadaharu Oh before Friday's Japan Series matchup to toss out the ceremonial first pitch at the Tokyo Dome. 

Kennedy, daughter of U.S. President and noted Red Sox fan John F. Kennedy, was appointed ambassador in 2013. She welcomed several MLB stars to a reception at her residence before the game, and they were kind enough to offer her an autographed base in return:

Oh, on the other hand, is a Japanese Hall of Famer who, in his 22 seasons as a player, hit a record 868 home runs -- the most by any Japanese player. In fact, Oh had a friendly rivalry with former MLB home run leader Hank Aaron, and the two actually competed in a legendary home run derby in Japan:

The two tossed our their ceremonial offerings to free-agent outfielder Nori Aoki and Hall of Famer Dave Winfield, who both made the catch without a problem.
