Bryan Woo – Seattle Mariners Biography, Contract, Net Worth Information

Bryan Woo has wasted no time making an impact in Major League Baseball since he debuted with the Seattle Mariners on June 3, 2023.

At just 25, the Oakland native has already become a solid piece of the Mariners’ pitching rotation after they picked him in the 6th round of the 2021 MLB Draft out of Cal Poly.

Bryan Woo’s current contract is a one-year deal with the Seattle Mariners, worth $783,300. It’s fully guaranteed and that number also marks his average annual salary.

Woo also picked up a hefty $362,483 bonus through the arbitration pool—nearly half his salary for the season. Not bad for a young pitcher just getting started.

He’s still early in his career, but Woo has already started building his financial base. His net worth sits at about $782,720 right now, and if things keep trending upward for him on the mound, that number should rise fast.

When he signed with the Mariners, they gave him $318,200—just above the $286,500 slot value. Even in his short time in the majors, Woo has seen his earning power climb as he carves out his spot.

Early Life and Baseball Beginnings

Bryan Woo’s road to pro baseball started long before he ever put ink to his Mariners contract.

He put in the work early, showing the drive and skill that would eventually get him to the big leagues.

High School and Amateur Career

During high school, Woo stood out as a real prospect. He had the size (6’2″, eventually 205 pounds) and the kind of arm scouts love.

He threw right-handed with smooth mechanics, which helped him separate himself from other players in amateur circuits.

His high school stats aren’t widely available, but he did enough to catch the eyes of college recruiters.

Woo kept developing his pitch mix and sharpened his command. He impressed in local competitions and showcases, getting noticed by colleges across the western U.S.

College Performance and Draft

He took his talents to college, where he kept honing his pitching skills. Those college years were big for his growth, facing tougher hitters and getting guidance from coaches.

By 2021, Woo’s game had come far enough to draw serious MLB scout interest. His college outings showed he had what it took to turn pro.

The Mariners picked him on draft day and signed him for $318,200, a bit over the slot value. That signing bonus made it clear the Mariners saw real potential in him as a future starter.

His journey from amateur ball to pro prospect is a path a lot of big leaguers know well.

Professional Baseball Career

The Seattle Mariners selected Bryan Woo in the 2021 MLB Draft, kicking off his pro baseball career.

Woo’s rise through the minors was quick, and he made his mark with strong debuts and a good dose of resilience after battling some injuries.

MLB Debut and Initial Performance

Bryan Woo made his MLB debut on June 3, 2023 with the Mariners. He came out of Cal Poly as a sixth-round pick (174th overall) and got a $318,200 signing bonus.

He climbed the minor league ladder in less than two full seasons before getting called up.

When he first hit the big leagues, Woo showed off his command and velocity—qualities that caught the Mariners’ coaches’ attention.

In his rookie season, Woo pitched with a calmness you don’t always see in young arms. He handled tough innings against veteran hitters.

His four-seam fastball and developing slider became his go-to pitches as he settled into MLB competition.

Notable Seasons and Teams

Woo has played his entire pro career with the Mariners organization.

His first season gave fans a glimpse of his upside as a starter, with several strong outings that helped the Mariners during a playoff push.

In 2024, Woo competed for a rotation spot in spring training. His performance earned him a serious look for the starting five, showing his growth at the highest level.

By the 2025 season, Woo had cemented his place in the Mariners’ pitching staff.

His contract is still very team-friendly, with a $783,300 salary for 2025. That’s a bargain for a starter, especially since the team controls his rights for a while.

Some of Woo’s standout moments:

• Posting career-high strikeout games
• Pitching multiple 6+ inning outings with few earned runs
• Delivering strong starts at T-Mobile Park

Injury and Recovery

Woo, like a lot of young pitchers, has dealt with injuries along the way.

He spent a chunk of his early pro career rehabbing from an arm injury he picked up in the minors. The Mariners handled his recovery with extra care.

They limited his innings and watched his pitch counts closely. That plan worked—Woo made it back without losing his stuff.

During the 2024-2025 offseason, Woo focused on strength and injury prevention programs. The Mariners’ trainers have praised his approach to conditioning and recovery.

His ability to bounce back from setbacks shows off his mental toughness. The Mariners’ investment in his health seems to be working, as Woo keeps building up his stamina and durability.

Contract Details and Salary

Bryan Woo now pulls in a base salary of $720,000 with the Mariners.

That contract fits his status as a young pitcher who is still early in his MLB journey, though he’s already earned some solid bonus money through performance-based pay.

Current Contract Terms

Woo’s salary is $720,000 per year with Seattle.

Because the Mariners drafted him in the 6th round (174th overall) in 2021, he’s still on his rookie contract and under team control. He hasn’t hit arbitration yet—that usually comes after three full MLB seasons.

There’s no signing bonus listed in the current contract info, and his net worth sits at around $782,720.

The Mariners have Woo on a team-friendly deal, which gives them great value for a starting pitcher these days.

Salary Progression

Woo debuted in the majors on June 3, 2023, and his earnings have gone up thanks to performance bonuses.

He picked up $362,483 in bonus money through MLB’s pre-arbitration bonus pool, which came out of the latest collective bargaining agreement.

That bonus is about half his base salary—a nice boost for a young pitcher. If Woo keeps progressing, his salary should jump when he reaches arbitration.

At 25 (born January 30, 2000), Woo gives the Mariners a lot of value for their payroll. Young, effective starters on pre-arbitration contracts help teams stay under the luxury tax.

Net Worth and Financial Insights

Bryan Woo has already built a decent financial foundation early in his MLB career. His contract and future investment opportunities set him up for more growth as he keeps moving forward.

Investments and Endorsements

Woo’s net worth is currently estimated at $782,720, mostly from his baseball earnings.

He hasn’t landed any major endorsement deals yet, which isn’t unusual for a newer MLB player.

Right now, Woo seems to be focused on his game rather than branching out into investments or endorsements like some veterans do.

Analysts think young pitchers like Woo usually start exploring endorsement opportunities after a few solid seasons, or if they hit big milestones like All-Star nods.

Financial Outlook

Woo’s financial future looks bright if he keeps trending upward.

His annual salary of $783,300 with the Mariners is just a starting point.

Pitchers who lock down a rotation spot often see big paydays when they hit arbitration or free agency. Top starters can land multi-year deals worth $10-20 million a year.

The Mariners have a reputation for developing young arms, which should help Woo’s earning potential if he stays healthy and keeps improving.

Typically, MLB players follow this path:

• Pre-arbitration: League-minimum salaries
• Arbitration: Big raises based on performance
• Free agency: Possible huge contracts

Of course, health is the wild card—pitcher longevity makes all the difference for lifetime earnings.

Impact on Teams and Trade Rumors

Bryan Woo has quickly become a valuable piece in the majors, catching the eye of other teams while carving out a key role for the Mariners.

His upside and progress have made him both a cornerstone in Seattle and a name that comes up in trade talks.

Role on the Mariners’ Rotation

Woo has emerged as a core member of the Mariners’ pitching staff, joining a rotation with Luis Castillo, Logan Gilbert, George Kirby, and Bryce Miller.

The 25-year-old righty gives Seattle a young, controllable arm that fits their pitching-first approach.

Jerry Dipoto, the Mariners’ President of Baseball Operations, has openly praised Woo’s growth and upside.

Within the Mariners’ focus on young pitching, Woo stands out as a success story from their development pipeline.

His $783,300 salary for 2023 makes him a huge value from a payroll perspective, giving Seattle flexibility while keeping their rotation strong.

Trade Rumors and Market Value

Lately, trade rumors have linked Woo to the Boston Red Sox. If a deal goes through, he might actually become a key part of their push for a championship.

Some reports toss around the idea of a multi-player swap. Seattle would send Woo to Boston and, in return, finally get the offensive boost they’ve been craving.

Craig Breslow leads the Red Sox these days, and you get the sense he sees Woo as a long-term rotation guy. Maybe even as a complement to players like Triston Casas, who could also be on the move.

Woo’s team-friendly contract and years of control really bump up his trade value. Teams love that kind of flexibility, don’t they?

Apparently, the Padres, Yankees, and Dodgers have also shown interest. They all want cost-controlled starters with some upside.

Now the Mariners have a tough call to make. Should they hang on to their promising arm, or trade Woo away to fix their lineup’s nagging issues?
