Kazuma Okamoto, a talented third baseman and first baseman, is expected to become an international free agent following an unusual decision by the Yomiuri Giants of Nippon Professional Baseball (NPB). Traditionally, the Giants refrain from posting their key players. However, they are now willing to allow Okamoto to explore opportunities in Major League Baseball (MLB) this winter.
Kazuma Okamoto’s Career Highlights
- Joined the Yomiuri Giants in 2018.
- Achieved six All-Star selections and three Gold Glove awards.
- Maintained an impressive batting average of .277 with a .361 on-base percentage and .521 slugging percentage.
- Accrued 274 home runs, showcasing consistent power hitting.
- Demonstrated a low strikeout rate, even in an injury-shortened season last year.
Recent Performance and Statistics
In the previous season, despite playing only half the games due to injuries, Okamoto recorded a .322 batting average and a high on-base percentage of .511. He struck out just 38 times in 314 plate appearances, resulting in a remarkable 210 weighted Runs Created Plus (wRC+) according to FanGraphs.
Concerns and Metrics
Despite impressive statistics, there are questions regarding how Okamoto’s performance will translate to MLB, particularly against fast pitches exceeding 94 MPH. FanGraphs analyst Eric Longenhagen noted that Okamoto’s results significantly drop under these conditions. He faced only 200 fastballs over 94 MPH last season, raising concerns among potential suitors.
Nevertheless, Okamoto has shown improvement in areas such as walk rates, breaking the 10% mark in the last three seasons. His swing-and-miss rate has also decreased, indicating his ability to improve his plate discipline.
Position and Future Prospects
Okamoto has experience playing third base, first base, and left field. However, he is primarily projected to play first base due to his age. Recently, he has spent over 60% of his games at third base, logging more than 400 innings there in 2025.
Potential Fit for MLB Teams
One team that could significantly benefit from acquiring Okamoto is the Seattle Mariners. The Mariners are currently assessing options to improve their roster. While Eugenio Suárez has been a reliable player, his age and potential contract demands create openings for younger talent.
- Suárez will turn 35 next year, affecting future projections.
- Ben Williamson is still developing and may not be ready for a full-time role next season.
Market Value and Contract Expectations
The financial implications of signing Okamoto are substantial but manageable. Recent contracts for Japanese players provide valuable context. For instance, Masataka Yoshida signed for five years at $90 million, while Seiya Suzuki’s deal was for five years at $85 million. Okamoto’s market value is estimated to be in the ballpark of five years for approximately $100 million, along with a posting fee of about $16.875 million.
This total cost of approximately $116 million is competitive compared to the Mariners’ past contracts, such as Robbie Ray’s five-year, $115 million deal.
Conclusion
In summary, Kazuma Okamoto is a player the Seattle Mariners should pursue seriously. He addresses an immediate need within their roster and brings valuable skills that align with the team’s competitive ambitions. Given the right investment, Okamoto could prove to be a transformative addition to the Mariners as they continue to build for future success.
