Norihiro Nakamura went 4-for-5 with a homer and five RBIs as the Tohoku Rakuten Golden Eagles outlasted the Hokkaido Nippon Ham Fighters 9-6 in 11 innings Sunday to complete their first season-opening series sweep in club history.

Nakamura, who signed as a free agent from the Chunichi Dragons, hit a two-run home run in the first inning and tied the game at 6-6 in the ninth with his second RBI single of the afternoon at Sapporo Dome.

The third baseman then doubled in the go-ahead run in a three-run 11th against Yataro Sakamoto (0-1).
