Analyzing Logan Gilbert and Bryan Woo’s Contract Extension Prospects
The Seattle Mariners have solidified their position as playoff contenders, largely thanks to a strong pitching lineup. Among the key contributors are Logan Gilbert and Bryan Woo, two homegrown talents whose future with the team is under consideration. Recent reports indicate that the Mariners are actively exploring contract extensions for both pitchers as they look to secure their pitching staff.
Logan Gilbert’s Performance and Prospects
Logan Gilbert made his MLB debut in 2021 and has since established himself as a reliable member of the Mariners’ rotation. Over 840 and two-thirds innings, he has a commendable ERA of 3.59, paired with a 26.2% strikeout rate and a low walk rate of 5.3%. His durability has been evident, as his first trip to the injured list came in 2025 due to a right elbow flexor strain, but he returned to form quickly.
In the 2025 season, Gilbert made 25 starts, achieving a 3.44 ERA and a career-high strikeout rate of 32.3%. Given his track record, he is regarded as a valuable asset to the team. Current discussions around a contract extension for Gilbert, however, remain preliminary, with reports suggesting more financial implications due to his impending free agency.
Comparative Extensions for Gilbert
Gilbert’s potential extension is likely to be in the range of $85-90 million over four years. Comparatively, players like Pablo Lopez and Mitch Keller have signed recent extensions that could inform Gilbert’s contract discussions. Lopez signed a four-year deal worth $73.5 million in April 2023, while Keller received $71.6 million for four years in February 2024.
Bryan Woo’s Emerging Role
At 26, Bryan Woo debuted in 2023 and has made a significant impact, boasting a 3.21 ERA through 70 career starts. He has similar strengths to Gilbert, demonstrating an ability to generate strikeouts while maintaining a low walk rate. In 2025, Woo made 30 starts, recording 21 quality starts, which positions him as an essential part of the Mariners’ pitching future.
Future Contract Considerations for Woo
Woo is currently under club control through 2029, making him a strategic candidate for extension discussions. Comparisons have been drawn between Woo and players like Cristian Javier and Tanner Bibee, both of whom signed extensions under similar circumstances. Woo may seek a contract valued around $55 million over four years with an average annual value of $13.75 million.
Financial Considerations for the Mariners
The Mariners currently have four guaranteed salaries totaling approximately $75.31 million for the 2027 season. Key players such as Luis Castillo and Julio Rodriguez are among this group. Given these financial commitments, the Mariners may have sufficient flexibility to extend at least one of their promising pitchers, ensuring they maintain a competitive roster going forward.
- Logan Gilbert: 3.59 ERA, 840.2 innings, 32.3% strikeout rate
- Bryan Woo: 3.21 ERA, 70 starts, 21 quality starts in 2025
- Potential Extension for Gilbert: $85-90 million over four years
- Potential Extension for Woo: $55 million over four years
- Total Guaranteed Salaries (2027): $75.31 million
As the Mariners assess their options, fans can only hope for positive outcomes in the ongoing negotiations with both Gilbert and Woo. These extensions could play a significant role in the team’s success in the upcoming seasons.
