Kohei Arihara allowed no runs for the second straight start, pitching the Hokkaido Nippon Ham Fighters to their 13th straight win, a 4-0 Pacific League victory over the Chiba Lotte Marines on Saturday.
The Fighters' win streak is Japan's longest since they won 14 straight in 2007. The PL and Nippon Professional Baseball record is 18 straight, set by the 1954 Nankai Hawks.
Arihara (9-3), last year's PL Rookie of the Year, worked eight innings for the second straight game, allowing three hits and a walk, while striking out five.
