Softbank Hawks pitcher Haru Matsumoto started for the White team in an intrasquad game at the Miyazaki training camp on the 14th, pitching two innings, allowing only one hit and no runs, and struck out out four of the seven hitter. His maximum speed was 147 km/h. After leaving the game, he threw about 40 pitches in bullpen, working on improving his control of breaking ball.

Last season, he appeared in 29 games, including 15 starts, with a record of 6 wins and 6 losses and ERA of 2.76. This season, he is expected to hold down the starting rotation spot left vacant by Arihara for the entire year. "I'm still in the stage of getting better from here. I was able to stand on mound and pitch with a clear intention today. Last season was full of regrets. This year, I want to produce results that I can be truly satisfied with. I'm definitely pitching better than last year," he said, expressing his confidence.
