DALLAS -- Hard-throwing Japanese right-hander Roki Sasaki was posted to Major League Baseball teams and will be available to sign as a free agent from Tuesday through 5 p.m. ET on Jan. 23.

The Chiba Lotte Marines said Nov. 9 that they planned to make the 23-year-old Sasaki available but waited until less than a week before the end of the posting period.

Because he is 23, Sasaki is considered an international amateur by MLB and is limited to a minor league contract subject to the international signing bonus pools usually allocated for 16-year-old Latin American prospects. The 2024 signing period ends Sunday and the 2025 period opens on Jan. 15, with team pools ranging from $7,555,500 to $5,146,200.

Teams may trade for additional pool allotment in $250,000 increments starting Jan. 15 but are limited to adding 60% of their initial amount.

Chiba will receive a posting fee from the acquiring MLB team equal to 25% of the signing bonus.

When Shohei Ohtani agreed to join the Los Angeles Angels in December 2016 at age 23, he received a $2,315,000 signing bonus. Ohtani had salaries of $545,000, $650,000 and $259,259 (in pandemic-shortened 2020) during his first three seasons, earned $3 million, $5.5 million and $30 million in his three years of arbitration eligibility and then agreed to a record $700 million, 10-year contract with the Los Angeles Dodgers ahead of the 2024 season.

Sasaki is represented by Joel Wolfe of Wasserman Media Group and is expected to become one of the most sought-after pitchers on the market. He went 10-5 with a 2.35 ERA in 18 games this year, striking out 129 hitters in 111 innings.

Sasaki helped Japan win the 2023 World Baseball Classic. His fastball has been clocked at 102.5 mph, and he has a 29-15 career record with a 2.10 ERA over four injury-shortened seasons with the Marines. He pitched a perfect game against the Orix Buffaloes in April 2022 -- racking up 13 straight strikeouts and finishing with 19.

"Since I joined the team, the team has been listening to my thoughts about my future MLB challenge, and I am very grateful to the team for officially allowing me to post," Sasaki said in a Nov. 9 statement posted by the Marines on the social platform X.

"There were many things that did not go well during my five years with the Marines, but I was able to get to this point by concentrating only on baseball, with the support of my teammates, staff, front office, and fans. I will do my best to work my way up from my minor contract to become the best player in the world, so that I will have no regrets in my one and only baseball career and live up to the expectations of everyone who has supported me."
