It was only 10 days ago that Shingo Usami recorded his first pro hit. After his last swing of the bat on Friday night, the Yomiuri Giants youngster can check his first home run and first game-winning hit off the list as well.

Usami hit a two-out, two-run sayonara home run to right in the bottom of the 10th, and the Yomiuri Giants won a seesaw battle against the Yokohama BayStars 9-7 at Tokyo Dome.

"I hadn't had one (a sayonara hit), at least not on the top team," the 24-year-old Usami said. "I had one last year in the Eastern League."
