Seibu Lions On February 24, the second-year left fielder Sou Sato pitcher (22), a left fielder in his second year of training with the Japan Professional Baseball League (JPSL), made his first start at the first team camp in the spring training camp that begins on February 1, and was enthusiastic, saying, "I hope to be under control for the opening day of the season.

He joined Seibu Lions as the fourth pick in the 2012 development draft from Seisa Dohto University. Although he was unable to be promoted to the regular team in his first season last year, he made it into the starting rotation for the second team midway through the season.

When it was decided that he would pitch in a first-team game, he said, "I can go anywhere," and was prepared to swing his arm wherever he was assigned, without any preference for reliever. Since joining the team, he had thought, "This is going to be a challenge," and in his second year, he has made a good start by joining the first-team camp, and he is excited as he approaches February 1st, saying, "I want to make an impression in areas like control, pickoffs, and fielding. I'll go in (to bullpen from day one) and make an impression from the start, and I hope to be able to aim for a controlled start."
