Nagisa Arakaki walked none and pitched a four-hitter in a complete game effort Tuesday to carry the front-running Daiei Hawks past the second-place Seibu Lions 4-2 and to their first victory in four games in the Pacific League.

Arakaki (9-4) limited the damage to a Shogo Akada two-run homer in the fourth inning in going the distance for the fourth time in as many starts and outdueling Chang Chih-chia (7-6) at Seibu Dome for a team-high ninth win.

Chang came within an out of a complete game but was relieved after he allowed four runs and six hits.

Hisao Arakane, who started in place of Tadahito Iguchi, hit the first game-opening leadoff homer of his four-year career and Pedro Valdes followed with a two-run drive as Daiei built a 4-0 lead through the third.
