The Tokyo Yakult Swallows struck first, but all they did was awaken a bunch of sleeping Yomiuri Giants.

Michihiro Ogasawara homered and drove in four runs, and Hayato Sakamoto chipped in with a three-run homer to help the Giants put away the third-place Swallows 10-7 on Friday at Tokyo Dome.

The Central League leaders trailed 1-0 in the first when Ogasawara sparked a four-run inning with a two-run double to right field.
