Rōki Sasaki Autographs
Roki Sasaki (Japanese: 佐々木 朗希, Hepburn: Sasaki Rōki; born November 3, 2001), nicknamed "the Monster of the Reiwa Era" (令和の怪物, Reiwa no Kaibutsu), is a Japanese professional baseball pitcher for the Los Angeles Dodgers of Major League Baseball (MLB). He has previously played in the Nippon Professional Baseball (NPB) for the Chiba Lotte Marines. He made his NPB debut in 2021 for the Marines and signed with the Dodgers in 2025.
Sasaki set a new Japanese high school baseball record with a fastball recorded at 101 miles per hour (163 km/h). The Marines chose Sasaki in the first overall selection of the 2019 NPB draft. Taking care to avoid subjecting their rookie to premature physical stresses, the Marines held back until the 2021 season before allowing him to make his NPB debut. He threw a perfect game on April 10, 2022, in which he tied the NPB record for strikeouts in one game and set a new record for consecutive strikeouts.
Sasaki is from Rikuzentakata in the Iwate Prefecture. Born in 2001, he was named after the villain Rouki from Hyakujuu Sentai Gaoranger, a Super Sentai show that was aired in the same year. He was in the third grade during the 2011 Tōhoku earthquake. The resulting tsunami swept away his house. His father and grandparents died, while Sasaki, his mother, and his two brothers had to live in a nursing home during the recovery. The family moved to Ōfunato the next year and Sasaki began to play baseball at his new school. He graduated from Ōfunato High School.
