Sho Nakata has become the Seibu Lions' biggest nightmare. The Hokkaido Nippon Ham Fighters cleanup hitter homered twice on Friday, driving in five runs and driving a wedge into the Lions' pennant pretensions.

The Fighters' 5-0 victory at Sapporo Dome boosted their Pacific League lead to three games over the Lions and lowered Nippon Ham's magic number to win the pennant to four. Nakata's big night came six days after he drove in four runs to lead the Fighters to a crucial come-from-behind victory over the Lions at Seibu Dome.

Nippon Ham lefty Mitsuo Yoshikawa (14-5) allowed two hits and a walk in his third shutout of the season. He struck out seven en route to lowering his ERA to a league-leading 1.71.
