Kyohei Muranaka made his return to the Tokyo Yakult Swallows under the bright lights at the Big Egg.

If that affected him at all, he never let it show.

Muranaka threw six innings of one-run ball, and Hiroyasu Tanaka provided the winning margin with a solo home run to lead off the sixth inning as the Swallows beat the Yomiuri Giants 2-1 on Friday night at Tokyo Dome.
