Kazuma Okamoto belted two home runs to help the Yomiuri Giants clinch a playoff spot with a 9-4 win over the Hanshin Tigers on Tuesday.

Okamoto broke a 4-4, seventh-inning tie with his 32nd home run of the season. The 22-year-old then put the icing on the Giants' cake with a two-run shot in the eighth, giving him 100 RBIs for the season.

"I failed to hit my first three times up. Twice my teammates presented me with run-scoring opportunities. I could have opened the scoring in the first and then I could have brought us from behind the second time," said Okamoto, who opened the game 0-for-3.
