Tuesday turned out to be unexpectedly cool in Japan's capital city, but the Tokyo Yakult Swallows may have finally started to heat up.

Kazuhiro Hatakeyama homered for the third time in two games and starter Masanori Ishikawa did just enough as the Swallows beat the Chunichi Dragons 4-2 on a cloudy afternoon at Jingu Stadium.

After going winless in their first four games to start the year, the Swallows have now won two straight.
