LOS ANGELES — Prized Japanese pitcher Roki Sasaki says in an Instagram post he intends to sign with the World Series champion Los Angeles Dodgers.

A 23-year-old right-hander whose fastball tops 100 mph, Sasaki will join fellow Japanese stars Shohei Ohtani and Yoshinobu Yamamoto in a move many baseball executives long expected.

The San Diego Padres and Toronto Blue Jays were said to be the other finalists pursuing Sasaki, who has until next Thursday to complete a contract.

Los Angeles has up to $5,146,200 available in its international signing bonus pool, though the Dodgers could make trades in the next week to increase the amount by up to 60%.

Dodgers Plan 6-Man Rotation for 2025

The Dodgers are planning to use a six-man rotation, which could ease Sasaki’s transition to MLB, as the Dodgers attempt to become the first repeat champion since the New York Yankees from 1998 to 2000.

Sasaki was made available to Major League Baseball teams by the Chiba Lotte Marines of Japan’s Pacific League under the posting agreement between Nippon Professional Baseball and MLB.

Because he is under 25 and does not have six years of service time in NPB, Sasaki is considered an international amateur by MLB and limited to a minor league contract subject to the signing pools.

The Marines will get a release fee calculated at 25% of the amount of Sasaki’s signing bonus.

Sasaki Went 10-5 Last Season

Sasaki was 10-5 with a 2.35 ERA in 18 games last year, striking out 129 hitters in 111 innings during a season limited by shoulder inflammation. He went 7-4 with a 1.78 ERA in 15 starts in 2023, when he had an oblique injury. He has a 29-15 career record with a 2.10 ERA over four seasons with the Marines and pitched a perfect game against Orix in April 2022.

The Dodgers’ first spring training workout is on Feb. 11 at Glendale, Arizona, ahead of their opening two-game series against the Chicago Cubs in Tokyo on March 18 and 19.
