Over the last year, there had been speculation around MLB that the Dodgers had a possible handshake agreement in place with pitcher Roki Sasaki.

The Los Angeles Dodgers aren't ruining baseball following their latest Roki Sasaki signing — they're just better at it than everyone else in MLB.

Sasaki's nickname is a tribute to legendary Japanese starting pitcher Daisuke Matsuzaka, who was known as the "Monster of the Heisei," referring to different eras of the Japanese calendar. The 23-year-old lost both his father and grandfather during the 2011 Tohoku earthquake and tsunami.

The 23-year-old Japanese phenom has a fastball that regularly reaches triple digits and wowed MLB scouts at the World Baseball Classic in 2023.
