The Chiba Lotte Marines recorded two walk-off victories against Rakuten this past weekend: 13-12 on May 14 and 9-8 on May 15. The twenty-two runs they scored is most for back-to-back walk-off victory NPB games since 1950. The previous record of twenty-one was set by Yokohama in 1998: an 8-7 win over Yomiuri on July 14 and a 13-12 win over Yomiuri on July 15.
Lotte also became the first team to score a total twenty or more runs in back-to-back victories since Yakult in 1993 (14-7 win against Hiroshima on May 18 and 17-16 win against Hiroshima on May 19).
This marked the first time Lotte recorded back-to-back walk-off extra-inning victories since 2013 (against Orix, March 29 and 30).
