DALLAS — Tuesday was a noteworthy day in the offseason.

Japanese pitcher Rōki Sasaki was officially posted as a free agent, beginning a 45-day window in which he can sign with any of the 30 major league teams.

Last month, his club, the Chiba Lotte Marines of Nippon Professional Baseball, announced they would post him, causing a frenzy throughout the baseball world.

After all, Sasaki is incredibly touted and will be available to all teams for relative peanuts — since he hasn’t met the requirements of playing a minimum of six seasons in Japan. That means he comes over as an international free agent who will be subject to international bonus pool money restrictions.

Shohei Ohtani had a similar process when he came over in 2017 and signed for $2.315 million with the Angels.

Sasaki is a 23-year-old right-hander who has posted eye-popping numbers in his 4 seasons in Japan – 30-15 record, 2.02 ERA, 0.88 WHIP, 11.4 K/9.

Sasaki’s main concern over the last few months hasn’t been about what team to sign with or where he could end up, though. The uncertainty of his posting loomed over him and stopped him from sharing what he is exactly looking for in teams with his agent Joel Wolfe.

“My first answer is, I’m not entirely sure yet, because I’ve known Rōki for a little over two years now, and as I’ve gotten to know him, it’s been a little bit difficult to really ascertain what his decision-making process would be for choosing a team, because his focus has predominantly been on whether or not he’s going to be able to post,” Wolfe said at a press conference on Tuesday morning at the Hilton Anatole Resort.

Sasaki, though, has done some preliminary homework.

“He’s paid attention to what his WBC teammates have done,” Wolfe said. “He’s talked to a lot of players, foreign players that have been on his team with Chiba Lotte.

“He asked a lot of questions about weather, about comfortability, about pitching development and just watching what other Japanese players in the major leagues are doing and how they are doing.”

Some of those could benefit the Cubs’ pursuit of the young, Japanese phenom.

The Cubs have made a conscious effort in trying to improve the transition for players coming over from Japan. They learned lessons from Seiya Suzuki’s first few years in the United States and some of the challenges he faced, applying them to Shota Imanaga and his first season.

Imanaga was an instant hit, developing into the Cubs’ ace in 2024 and fitting in almost seamlessly with his team and fans. Imanaga was a teammate of Sasaki’s on Team Japan that won the 2023 World Baseball Classic.

But Wolfe insisted that Sasaki and teams are in the infancy of his free agency and no team has been chosen or eliminated.

“So as far as the process going forward now, I wanted to make sure that we left it a little open-ended,” Wolfe said. “Having been through this before with other players, I didn’t want to have some type of hard cookie-cutter system. Cookie cutter meaning some predetermined system.

“Our plan is I will go back tomorrow sometime, hope to meet with Rōki in person over the next couple of days and map out a schedule to meet with teams, hopefully beginning next week.”
