Daiei right fielder Hiroshi Shibahara drove home four runs and rookie hurler Nagisa Arakaki pitched five-plus innings to notch his his third win as the Pacific League-leading Hawks downed the Nippon Ham Fighters 9-4 at Tokyo Dome on Monday to extend their win streak to five games.

Trailing 1-0 in the third, Shibahara nailed a two-run homer off Nippon Ham starter Carlos Mirabal (4-4) to give Daiei the lead.

Shibahara hit a sacrifice fly to cap a five-run fourth-inning outburst and connected for an RBI single in the sixth.
