Miles Mikolas extended his winning streak from last season (June 20) to thirteen by winning his last start on July 31 against the Yakult Swallows at Tokyo Dome. He joins Tai-Yuan Kuo (thirteen between 1987 and 1988) and Rick van den Hurk (fourteen between 2015 and 2016) as the only foreign pitchers to record winning streaks of thirteen or more. Mikolas is the first to accomplish the feat in the Central League.
The last Yomiuri pitcher to record a winning streak or thirteen or more was Tetsuya Yamaguchi (all fourteen in relief between 2008 and 2009). The franchise high of twenty was set by Kiyoshi Matsuda between 1951 and 1952.
