Japan tour

The Orioles made its second Yomiuri Shimbun-sponsored tour of Japan since 1971. The newspaper received approval from MLB on December 29, 1982 to invite the winner of the 1983 World Series to play 15 games against Nippon Professional Baseball competition, primarily the 1984 Japan Series champion. Yomiuri owner Tōru Shōriki originally wanted to invite the 1984 World Series winner, but eventually agreed to MLB Commissioner Bowie Kuhn's suggestion of the previous year's World Series champion. The exhibition matches were intended to be part of the golden jubilee celebration for the Yomiuri Giants which was owned by the tour's sponsor and another attempt by Shōriki for his team to make a legitimate claim at being world champions of the sport. The Orioles accepted the invitation on January 2, 1984, 2 1/2 months after winning the 1983 World Series. The Yomiuri was eventually left disappointed when both the Orioles and its Giants failed to qualify for the postseason with fifth- and third-place finishes respectively. Instead of the Giants for which the event's organizers had hoped, the opponent in the first five matches was the 1984 Japan Series champion Hiroshima Toyo Carp. Eight of the games featured both players who surpassed Lou Gehrig's consecutive games played streak. Cal Ripken Jr. and Sachio Kinugasa batted .219 and .143 respectively. The fifteenth and final exhibition contest originally scheduled for November 15 in Baltimore's sister city Kawasaki was cancelled due to rain. Upon the Orioles' arrival in Tokyo on October 25, manager Joe Altobelli said he wanted his team to win at least 10 games. The Orioles finished the tour with an 8–5–1 record, including 4–1 each in head-to-head competition against the Giants and Carp.
