Takeya Nakamura hit a grand slam and John Wasdin picked up his first win back in Japan as the Saitama Seibu Lions rallied to beat the Tokyo Yakult Swallows 7-3 on Tuesday at Seibu Dome.

Nakamura's Pacific League-leading 18th homer came with the bases loaded and one out in the fifth inning off Masanori Ishikawa (6-3), breaking open a one-run game.

Wasdin (1-2), in his first season in Japan since 2002, allowed two runs and six hits in 6 1/3 innings.
