His background, physical tools, and role on the field show you exactly how he fits into the Sounders’ plans.
Personal Background
Jacob Castro grew up in Spanaway, Washington. People first noticed him as a multi-sport athlete.
At Spanaway Lake High School, he played soccer and also lined up as a wide receiver on the football team. That mix of sports really sharpened his instincts.
He joined the Sounders FC Academy in 2017 and made early appearances with Tacoma Defiance.
His college run started at the University of Washington and then took him to San Diego State. At SDSU, he picked up All-Pac-12 honors in both 2021 and 2022, even making First Team in 2021.
Castro’s rise didn’t happen overnight. By December 2022, Seattle signed him as a Homegrown Player, rewarding his years of hard work in the club’s system.
His story? It’s about making the most of local chances and turning them into a real pro career.
Physical Attributes
As a goalkeeper, size and reach matter a lot. Castro stands 6-foot-3, which lets him command the penalty area and challenge for balls in the air.
He covers his angles well, and his quick reflexes help him in one-on-one moments.
In 2024 with Tacoma Defiance, he started 17 matches and racked up 54 saves. Those stats show he handled a big workload and stayed focused all season.
His 80 percent passing accuracy? That’s a nod to his technical skills, which every modern keeper needs for building play from the back.
Key 2024 Tacoma Defiance Stats
| Matches | Saves | Clean Sheets | Passing Accuracy | Minutes Played |
|---|---|---|---|---|
| 17 | 54 | 2 | 80% | 1,530 |
These numbers highlight his reliability and growth as he takes on more with Seattle Sounders FC.
Jersey Number and Position
You’ll spot Castro by his No. 29 jersey, the number he wears in goal for Seattle Sounders FC.
For fans, that number signals his spot and identity within the team. Goalkeepers often wear numbers outside the traditional 1—29 is his stamp on the roster.
He plays as a goalkeeper, organizing the back line, stopping shots, and starting plays from the back.
The Sounders count on him for depth behind the starter, while he keeps pushing forward in training and cup matches.
Wearing No. 29, Castro stands as both a developing talent and a reliable option when the team calls his name.
His journey from academy hopeful to professional goalkeeper shows why his role means something for Seattle’s future.
Seattle Sounders FC Career
Jacob Castro’s journey to Seattle Sounders FC is all about patience, risk-taking, and steady progress.
He started competitive soccer a bit later, played college ball at Washington and San Diego State, and took a leap of faith to sign with his hometown club.
Now, he’s training with some of Major League Soccer’s most seasoned keepers.
Signing as a Homegrown Player
You watched Castro become a homegrown player in late 2022 when Seattle Sounders FC signed him to the first team.
That move capped years of growth in the Sounders Academy and a standout college run.
At the University of Washington, Castro picked up the basics of high-level goalkeeping.
His transfer to San Diego State allowed him to start full-time, where he earned All-Pac-12 honors in 2021 and 2022.
Those performances proved he could handle the pressure of a pro environment.
The Sounders signed him through the 2023 MLS season, with options through 2026. They locked in a young keeper with real local ties.
As a lifelong fan, Castro felt that first contract with Seattle on a personal level. It connected his early days in Spanaway and Tukwila to the pro game.
First Team Integration
Castro entered a crowded goalkeeper room, joining veterans like Stefan Frei and Stefan Cleveland.
Getting into the first team meant he had to adapt to the speed and intensity of MLS training sessions.
He hasn’t seen regular minutes in league play yet, but his spot on the roster adds depth and keeps competition sharp.
That role matters, especially during a long season with injuries or packed schedules.
As a backup, Castro observes Frei’s command of the box and Cleveland’s steady play.
For a young keeper, those daily lessons are gold—maybe even more valuable than game minutes.
You can track his progress by how quickly he adjusts to the demands of MLS, not just by starts.
Training and Development
Castro’s growth mostly happens on the training ground.
Under Tom Dutra, Seattle’s veteran director of goalkeeping, Castro focuses on technique, positioning, and decision-making.
Dutra’s track record with Frei and others shows why this is a good place for a young keeper to develop.
Training sessions let Castro sharpen his reactions and work on his distribution.
Coaches like his athleticism and his drive to learn—traits that keep him in the club’s long-term plans.
Here’s a quick look at his early pro profile:
| Season | Club | Competition | Appearances | Starts | Honors |
|---|---|---|---|---|---|
| 2022 | San Diego State | NCAA | 18 | 18 | All-Pac-12 First Team |
| 2023 | Seattle Sounders FC | MLS | 0 | 0 | Homegrown Signing |
| 2024 | Seattle Sounders FC | MLS | Limited | 0 | Development Squad |
Right now, Castro’s career is still just getting started, but the training environment and structure around him give him the tools he’ll need for future chances.
Tacoma Defiance Experience
Jacob Castro laid his professional foundation with Tacoma Defiance, showing steady growth and improving his decision-making and distribution.
His time with the club proved he could handle a heavy workload, notch clean sheets, and make consistent saves in MLS NEXT Pro.
2024 Season Highlights
In 2024, Castro took on a bigger role, starting 17 matches for Tacoma Defiance and playing 1,530 minutes.
He faced a lot of action, responding with 54 saves, two clean sheets, and an 80 percent passing accuracy that showed his comfort on the ball.
That passing accuracy really stands out. For a goalkeeper, distribution is just as important as shot-stopping, and Castro’s ability to find teammates under pressure gave Defiance a real outlet when building out.
Check out his 2024 numbers:
| Matches | Minutes | Saves | Clean Sheets | Passing Accuracy |
|---|---|---|---|---|
| 17 | 1,530 | 54 | 2 | 80% |
The season showed you a keeper who could handle the physical grind and the technical demands of his spot.
His college background at Washington and San Diego State set him up for this step, and the results back that up.
2023 Performance
Back in 2023, Castro got 11 starts with Tacoma Defiance, made 53 saves, and picked up three clean sheets.
He didn’t play as many matches as in 2024, but he still faced plenty of shots, showing he could handle pressure and stay composed.
His save total nearly matched his 2024 output, even with fewer games. That says a lot about how often he was tested.
He picked up valuable experience against all kinds of attacking styles in MLS NEXT Pro.
| Matches | Saves | Clean Sheets |
|---|---|---|
| 11 | 53 | 3 |
You could already see signs of growth, as he balanced shot-stopping with better distribution.
Those games set the stage for his bigger role the next season.
Key Saves and Clean Sheets
Clean sheets can define a goalkeeper’s season, and Castro finished with five across 2023 and 2024 for Tacoma Defiance.
Each one took sharp positioning, fast reactions, and the ability to organize his defense.
His saves often came at big moments. In several games, he denied clear scoring chances that swung momentum for Defiance.
That 4-0 win over Ventura County FC, where he made six saves, stands out as a great example of his impact.
While clean sheets show consistency, those individual saves reveal his instincts and athleticism.
Those moments? They’re what separate a solid keeper from one ready to push for time with Seattle Sounders FC.
Collegiate Achievements
Jacob Castro’s college career tells a story of steady growth, tough competition, and some well-earned conference recognition.
His time at two Pac-12 programs gave him the chance to develop into a reliable starting goalkeeper known for consistency and shot-stopping.
University of Washington Huskies
Castro began at the University of Washington, spending two seasons with the Huskies.
He didn’t lock down a long run as the starter, but his time in Seattle gave him solid experience training in a competitive setting.
At Washington, he faced the tough task of breaking into a roster packed with experienced players. That kind of competition sharpened his skills.
The Huskies focused on defensive structure, so he learned how to organize a back line and communicate under pressure.
That foundation paid off later, when he moved on to a program where he’d take on a bigger role.
San Diego State Aztecs
Transferring to San Diego State finally gave Castro the chance to start regularly.
As the Aztecs’ primary goalkeeper, he became a key part of the team’s defense.
In 2021, he started all 17 matches, allowed just 16 goals, and notched seven shutouts. That kind of season shows his ability to control games, even against tough Pac-12 teams.
The next year, he played 16 matches and added three more shutouts. The numbers dipped a bit, but he still anchored the Aztecs’ back line and handled the grind of a full season.
San Diego State Goalkeeping Stats
| Season | Matches Started | Goals Allowed | Shutouts | Honors |
|---|---|---|---|---|
| 2021 | 17 | 16 | 7 | All-Pac-12 First Team |
| 2022 | 16 | N/A | 3 | All-Pac-12 Second Team |
All-Pac-12 Honors
You made a big impression at San Diego State. In 2021, you became the first Aztec goalkeeper since 2006 to earn a spot on the All-Pac-12 First Team.
That honor really showed off your consistency and knack for coming through in tough games.
In 2022, you grabbed an All-Pac-12 Second Team selection. Back-to-back recognition like that? It proves your high level of play wasn’t just a fluke or a one-year thing.
These awards put you among the conference’s best goalkeepers. You helped shine a brighter light on San Diego State’s program.
Starting out as a reserve at Washington, you showed clear and steady progress.
Youth and Early Development
Jacob Castro’s story doesn’t follow the usual script. He got a late start in competitive soccer, juggled time on the football field, and then switched to a goalkeeper role.
That move took him from Spanaway to the Sounders FC Academy, and then on to the University of Washington and San Diego State.
Sounders FC Academy Journey
You don’t hear this every day—a goalkeeper discovered by accident. That’s how Castro landed in the Sounders FC Academy.
In 2017, coaches noticed him while they were actually scouting someone else. His athleticism jumped out, even though he played for Washington Premier’s B-team.
The Sounders brought him into their academy for his senior year of high school. That invitation nudged him toward soccer full-time.
He trained with goalkeeper coach Josh Ford, who helped him sharpen his technique and positioning.
Castro’s academy stint exposed him to professional standards. He soon joined Seattle Sounders FC 2, the club’s reserve side, and picked up valuable minutes playing against older opponents.
Those experiences made college soccer feel a little less overwhelming. He kept growing at both Washington and San Diego State.
Key Development Points

Spanaway Lake High School
At Spanaway Lake High, Castro split his time between soccer and football. As a junior goalkeeper, he earned All-State honors.
He adapted quickly, even though he started competitive soccer later than most. His performances got noticed outside his hometown.
Juggling two sports wasn’t exactly easy, but it gave him a broader athletic background.
Coaches picked up on his fast reactions and ability to read plays. Those skills transferred well between football and soccer.
High school also helped him grow as a leader. Balancing sports and academics set him apart once he hit the next level.
High School Snapshot
| Sport | Position | Recognition |
|---|---|---|
| Soccer | Goalkeeper | All-State (Junior) |
| Football | Wide Receiver | Varsity Player |
Early Football Experience
Before soccer took over, Castro played two seasons as a wide receiver at Spanaway Lake.
That spot demanded speed, timing, and sure hands—traits that later served him well in goal.
You can see the connection when he comes off his line to grab a cross. The same hand-eye coordination he used on the football field helped him handle pressure in the box.
Football toughened him up, too. Competing in such a physical sport prepped him for the demands of top-level soccer.
By the time he focused on soccer, Castro brought along an athletic foundation built through football. It’s a background you don’t see in most goalkeepers.

That backstory makes him feel real to young players who didn’t start in some elite academy. People keep bringing up his late development—honestly, it’s a great example of sticking with it.
When Seattle Sounders FC announced his signing, they really leaned into his local roots. They made a point of saying he’s a homegrown goalkeeper who once stood with the fans at the 2016 MLS Cup parade.
