Lotte outfielder Koki Yamaguchi, a member of Samurai Japan competing in the 'Luxas Asia Professional baseball Championship 2026' (November 12-15 at Tokyo Dome), displayed incredible power on the second day of the Miyazaki training camp on the 4th. He cleared the fence 16 times out of 37 swings during free batting practice. On the first day, he hit 6 out of 31 swings. The slugger, whom Manager Iguchi has officially named as the number four hitter, is gaining momentum for this tournament.

Particularly in the first half against the right-handed batting pitcher, he hit 10 home runs in 16 swings. In the second half against the left-handed batting pitcher, he had 6 home runs in 21 swings, but his total home run rate was 43.2 percent.

During extra batting practice on the first day, Manager Iguchi informed him that he would be the 'number four' hitter. After the practice, he expressed his determination, saying, 'I was told I'd be batting fourth. I feel ready to go out there and get the job done.'

In this eighth season, he appeared in 113 games, recording a career-high 38 Home Runs and 81 RBI. With his talent fully blossoming, he joined the Samurai Japan team as an overage player.
