SAPPORO – Tadahito Iguchi and Katsuya Kakunaka each homered in the first inning off second-year right-hander Shohei Otani, who suffered his first career defeat on Sunday as the Chiba Lotte Marines beat the Hokkaido Nippon Ham Fighters 5-1 to complete a three-game sweep at Sapporo Dome.

The 19-year-old Otani (2-1) allowed five runs in seven innings. He gave up nine hits and walked a batter, while striking out nine. Otani, who is also a left-handed hitting outfielder, is currently batting .391 in 46 at-bats. His career record on the mound fell to 5-1.

“It’s not that big a deal for me as an individual, but it means as a team we have yet to beat Lotte and I wanted to win,” Otani said.

“Physically, I feel fine, and I wasn’t fatigued at the end.”

Otani was trailing by three runs before he retired his first batter. Shota Ishimine and Daichi Suzuki opened the game with back-to-back singles before Iguchi went deep for the fifth time this season. With one out, Kakunaka also homered to make it 4-0.

“I didn’t have real good arm action,” Otani said of the forkball he hung to Iguchi that reached the seats.

Marines rookie Ayumu Ishikawa (3-1) allowed a run on four hits over eight innings to earn the win. The right-hander struck out five and walked none.

The victory lifted the Marines, who have won all six of their games against Nippon Ham this season, into third place in the Pacific League standings.
