Pinch hitter Masahide Kaizuka hit a go-ahead RBI single in the Lions' three-run seventh inning at the Seibu Dome Thursday as Seibu came from behind to beat the Orix BlueWave 6-4 and climb into a first-place tie with the Daiei Hawks in the Pacific League standings.

Seibu starter Daisuke Matsuzaka (8-5) was rocked for four runs, three earned, over seven innings on nine hits but still got the win.

Shinji Mori worked the last two innings for his 15th save.
