Norihiro Nakamura smacked a solo homer in the top of the 10th inning to cap a stunning two-day series for the Kintetsu Buffaloes on Sunday as the defending Pacific League champions edged the Seibu Lions 4-3.

A day after Tuffy Rhodes hit a grand slam for the team's third straight victory, Nakamura hit his 16th home run of the season -- and his fourth in as many games -- off Seibu closer Shinji Mori with the game tied 3-3 at the Seibu Dome.

Seibu's Ken Suzuki forced an extra inning with a solo homer in the bottom of the ninth, but Mori (2-4) quickly surrendered the lead again on Nakamura's homer.
