Shinsaburo Tawata made his Ichi-gun debut on May 14 with a start against Nippon Ham at Sapporo Dome. He walked in three runners in a row in the second inning and became just the second rookie in NPB history to walk in three in a row in their debut game. The other rookie was Hiroshi Onodera on June 18, 1940. Two other rookies have also walked in three in a row (not in their debut games): Kazuyoshi Matsuura on December 6, 1936 and Takayasu Kato on August 16, 1994.
The NPB record of four was set by Takeo Mizobe on April 20, 1947. Since 1950 (start of the two leagues), fifteen other pitchers (eight Central League and seven Pacific League) have walked in three runners in a row. The last pitcher prior to Tawata was Yuya Kubo on August 14, 2014. Only one other pitcher in Seibu franchise history has walked in three runners in a row: Katsuhiro Maeda on July 18, 1995.
