Stefen Romero hit a walk-off RBI single in the ninth inning Wednesday to lift the Orix Buffaloes 5-4 over the Hanshin Tigers.

On the second day of the three-game Kansai Derby in western Japan, the Buffaloes avenged for the previous day's loss — their first and only defeat so far after eight games of interleague play — to the Tigers at Kyocera Dome Osaka.

Hanshin had built a 4-0 lead by the fourth inning, including a three-run home run by Masahiro Nakatani, but Takahiro Okada began the comeback with a solo homer in the fifth. Romero's no-out RBI hit to center sparked a three-run rally in the next inning to tie the game 4-4.
