High school and college Wakabayashi attended
President William McKinley High School, and his powerful fastball made him the ace pitcher of the school's baseball team. In 1928, he was chosen to participate in an exhibition baseball tournament held in Japan, and he traveled to Japan for the first time that year. Professional baseball did not exist in Japan at that time, and Wakabayashi's amateur team played against university teams in the
Tokyo Big6 Baseball League. Wakabayashi's pitching abilities did not go unnoticed, and
Hosei University was particularly active in recruiting him. Wakabayashi himself was not opposed to the idea of remaining in Japan, and it seemed only a matter of time before he was admitted into Hosei University. However, rival schools accused Hosei University of using unethical tactics to strengthen the baseball team, and the school decided to temporarily place Wakabayashi in a junior high school in
Yokohama, and admit him into the school the following year. Wakabayashi graduated from the junior high school in March 1929, and entered Hosei University the next semester. The
Tokyo Big6 Baseball League was dominated by
Waseda University and
Keio University, and the Hosei University team solely depended upon Wakabayashi's pitching to carry the team. He was unsuccessful in his first year due to differences between Japanese and American baseball, but gradually improved to win the league championship in Autumn, 1930. He injured his pitching arm in 1931, and had to switch to a side arm release to continue pitching. He was no longer able to throw fastballs, but improved his breaking pitches and control to continue his pitching success. Wakabayashi led Hosei University to a second league championship in 1932, and pitched in every single league game in 1934 to win a third championship. His record in the league was 43-28, and he holds the college league record for career games pitched (87). He was also the first pitcher to win 40 games in the
Tokyo Big6 Baseball League. He also married his wife in January 1933.
Professional and semi-professional career He graduated from the university in 1935, and a friend introduced him to the
Columbia Music Entertainment company, where he split time between working, and playing on the company's baseball team. In July 1935, the
Tokyo Kyojin Gun baseball team returned from their tour in the United States, and numerous companies, including the
Hanshin Electric Railway company, joined to form the first professional baseball league in Japan. Several companies made offers for Wakabayashi to join their professional team, and he signed with the Osaka Tigers (which later became the
Hanshin Tigers) in January 1936. Wakabayashi quickly emerged as the team's ace, and led the Tigers to championships in 1940 and 1944. Wakabayashi retreated to his wife's hometown in
Ishinomaki, Miyagi at the end of
World War II, but returned to professional baseball in 1947 to win his 200th professional game. He would mark 233 wins in his 13 seasons with the Tigers; the most among any Tigers pitcher in history. Wakabayashi doubled as a manager and player throughout the 1940s, and joined the
Pacific League Mainichi Orions in 1950, when the modern two-league system of Japanese baseball was established. He was already 42 years old at this time, and no longer had the energy to spend the entire season as a player, but still pitched in the first game of the Japan Series against the
Shochiku Robins, contributing to the Orions series championship in 1950. He also pitched a shut-out game against the
Kintetsu Pearls in November, 1950, setting the Japanese record for the oldest pitcher to record a shut-out win. This record lasted for almost 60 years until Masahiro Yamamoto broke it in 2010 at the age of 45. Wakabayashi announced his retirement in 1953, and he pitched his last professional game that year to mark his 1000th strikeout. He managed to reach the landmark, but handed his team the loss in the process. Though much of his success as a player came before modern Japanese baseball was established in 1950, he is still recognized as one of the legendary pitchers in Japanese baseball. He won the league MVP award in 1944 and 1947, and was inducted into the Japanese baseball hall of fame in 1964.
Post-playing career After retiring, he was given a position in the Mainichi franchise, but left after only one year to become a coach for the
Tombow Unions. He worked as a pitching coach for the
Taiyo Whales, and became the head coach for the
Nishitetsu Lions in 1963. He was diagnosed with stomach cancer in 1964, and left the Lions that year. He died on March 5, 1965, at age 57. ==Cultural impact==
