The interleague-leading Yomiuri Giants improved to 6-0 against the Pacific League this season, when former PL strikeout king Toshiya Sugiuchi pitched eight-plus innings in a 2-0 victory over the Seibu Lions at Seibu Dome on Wednesday.
Yomiuri is 9-0 with three ties since its last loss on May 5.
Sugiuchi, who led the PL in strikeouts in 2007 and 2008 before moving to the Central League this season as a free agent, outdueled Lions right-hander Takayuki Kishi, who fell to 4-4 despite a solid eight innings.
