The posting of Roki Sasaki by Japan’s Chiba Lotte Marines marks a significant development in baseball as the young pitcher, renowned for his 100 mph fastball and devastating splitter, becomes available for MLB teams. David Stearns of the Mets recently highlighted Sasaki’s unique potential, though there was initial uncertainty about his posting status.
With the Marines confirming his availability, Sasaki will soon join the MLB free-agent pool, likely becoming one of the top pitching assets available. Despite his impressive skill set, his youth and recent injury history bring some risk, which teams will need to consider in their pursuit.
The MLB-NPB posting system has evolved over the years to benefit Japanese players, who can now negotiate with any MLB team rather than relying on the silent auction approach used in earlier cases like Daisuke Matsuzaka and Yu Darvish. Now, Japanese teams receive a percentage of the MLB contract value, as seen in the record-breaking contract of Yoshinobu Yamamoto with the Dodgers. This revised system offers Japanese players more bargaining power and has changed the dynamics for MLB clubs trying to acquire top-tier talent from Japan.
However, Sasaki’s age, 23, introduces complications due to MLB’s rules on young international players, which limit their initial signing bonuses under the international bonus pool. Since Sasaki falls under this category, his signing bonus will be capped based on the limited funds each team has left in their 2024 bonus pool. Given that most teams have already allocated much of their pool for the year, the Marines are incentivized to delay his posting until the 2025 bonus pools reset in January, allowing clubs more financial flexibility to compete for Sasaki.
Money may not be Sasaki’s main motivator in this case; if it were, he could wait two more years until he turns 25 and bypasses the bonus pool limitations, allowing for a lucrative contract like Yamamoto’s. His decision to come to MLB now indicates a preference for factors beyond financial gain, such as fulfilling a dream to play in MLB. While the Dodgers may seem like an attractive destination due to their popularity in Japan and strong roster, previous Japanese players have chosen other teams for less obvious reasons. Ultimately, Sasaki’s preferences are not well known, making his decision hard to predict.
For the Mets, this uncertainty means Sasaki doesn’t need to be a central focus of their offseason plans. Their best approach to attract Sasaki might be to bolster their roster overall, potentially making high-profile moves for players like Juan Soto and Pete Alonso, and investing in pitching depth. Such efforts could increase their appeal as a competitive team without needing to compete purely on financial terms, though this strategy won’t guarantee Sasaki’s interest. The Mets, like other teams, will wait to see where Sasaki’s priorities lie once he’s officially posted.
