This is
post #2 about Tsuneo Horiuchi. He was the Giants ace from the mid 1960s. Many Japanese pitchers crumple under frankly insane workloads. Horiuchi’s workload was more reasonable than many (no 400 inning seasons for instance), but he was pitching full-time while he was still just 18, and was done as a full-time starter after his age 30 season. He finished with 203 wins, and qualified for the Meikyukai with his 200th win in 1980.
Horiuchi won the 1966 and 1972 Sawamura awards. (Baseball-reference says that he also won in 1974, but that appears to be an error.) In 72 he was also the MVP. In 1966 he was a young phenom, going 16-2 with a 1.39 ERA in 181 innings pitched as an 18 year old. His second win may not have been quite as exciting, but it was probably a more valuable season. He had a record of 26-9 to go with a 2.91 ERA in 312 innings.
