About the Seattle Steelheads

The Seattle Steelheads were a 1946 charter franchise of the Negro West Coast Baseball League — a short-lived Pacific Coast counterpart to the established Negro National League and Negro American League that operated in the eastern and central United States. The league existed for one summer in 1946; the Steelheads existed alongside the San Francisco Sea Lions, the Oakland Larks, the Los Angeles White Sox, the Portland Rosebuds, the Fresno Tigers, and the San Diego Tigers.

The league's vision was ambitious. The post-WWII Pacific Coast had a rapidly growing Black population, multiple major-league-quality ballparks, and dozens of NLB veterans either touring barnstorming circuits or looking for full-season organized league play in markets without color barriers. The Negro West Coast League was supposed to anchor that demand into permanent franchises. It failed to last beyond the 1946 season — operational and financial pressures, plus the rapid acceleration of MLB integration after Jackie Robinson's Brooklyn Dodgers signing in fall 1945, undermined the league's economic model — but the franchises themselves remain culturally important touchstones in West Coast Black baseball history.

The Seattle Steelheads were owned by Abe Saperstein — better known to history as the founder of the Harlem Globetrotters basketball franchise, which Saperstein had launched in 1926 and built into one of the most successful sports promotional operations in American history. Saperstein's interest in baseball ownership was both promotional and philosophical: he saw integrated entertainment as both economically sound and morally necessary. The Steelheads were one of several baseball ventures he attempted during his career, including a partnership in the Birmingham Black Barons.

The Steelheads played their home games at Sicks' Stadium in Seattle's Rainier Valley neighborhood — the home of the Pacific Coast League's Seattle Rainiers, a major-league-quality minor league ballpark with 11,000+ seating capacity. Sicks' Stadium would later host the 1969 Seattle Pilots in their single MLB season before that franchise relocated to Milwaukee.

Quick Buying Questions

What sizes do Steelheads jerseys come in?

Small through 5XL on virtually every jersey style. Hats are typically one-size-fits-most (snapback / flex) or fitted in standard cap sizes. We don't upcharge for big & tall sizes.

Can I add my name and number to a Steelheads jersey?

Yes — most styles offer free customization. Pick a Steelheads NLB veteran's name (Paul Hardy, Jesse Williams, Lefty Cox) or your own. Look for the "Custom" option on the product listing. Custom items are final sale and made to order, so allow 7–10 business days for production before shipping.

What's the difference between the Steelheads jersey styles?

Custom NLB Jersey — full personalization, period-correct construction. Flannel Jersey — premium heavyweight wool-blend in 1940s style. Remix Jersey — modern color or graphic interpretation. Replica Jersey — straightforward 1946 reproduction. NLB Remix Jersey — the Royal Retros NLB brand-line interpretation. Vintage Icons Jersey — alternative-history "what if" design featuring legendary NLB players in Steelheads colors.

How accurate is the design?

Color palette, lettering style, sleeve striping, and crest detail are reproduced from the limited surviving 1946 reference imagery. The Steelheads' visual archive is incomplete (one season meant limited photography), but we work from the best available material.

Were the Seattle Steelheads ever an MLB team?

No. The Steelheads played in the Negro West Coast Baseball League, which was a separate organization from MLB. However, after Major League Baseball's December 16, 2020 reclassification of the Negro Leagues operating between 1920 and 1948, several other NLB franchises became officially recognized major-league teams — the West Coast Baseball League itself was not one of the seven NLB organizations included in the 2020 reclassification, but the Steelheads remain a culturally and historically major-league-significant franchise.

Standard products ship within 3–5 business days. Custom items (those with personalized name/number) are made to order and ship within 7–10 business days. Custom items are final sale. Standard items follow our return policy at /pages/returns.

Gift Ideas for the Seattle Steelheads Fan

The Steelheads fan is a specific kind of baseball fan — Pacific Northwest-rooted, historically literate, often deeply invested in the under-told story of West Coast Black baseball. A Steelheads throwback connects to one of the most overlooked chapters in baseball history.

• For the Pacific Northwest sports fan: The Steelheads are Seattle's deepest baseball heritage. Older than the Seattle Pilots (1969), older than the modern Seattle Mariners (1977), the Steelheads represent Seattle's first organized professional Black baseball franchise. A deep-cut Pacific Northwest sports purchase.
• For the Negro Leagues historian: The 1946 Negro West Coast Baseball League is one of the great "what could have been" stories in baseball history. The Steelheads, alongside the San Francisco Sea Lions, Oakland Larks, and Los Angeles White Sox, represent a single-summer ambitious experiment in Pacific Coast Black baseball.
• For the Abe Saperstein fan: The Harlem Globetrotters founder owned the Steelheads. A Steelheads jersey honors the legendary Black sports promoter who built one of the most successful entertainment franchises in American history.
• For the Sicks' Stadium history fan: Sicks' Stadium hosted the Steelheads in 1946, the Seattle Rainiers PCL franchise from 1938 through 1968, and the Seattle Pilots in their lone 1969 MLB season. A Steelheads jersey is the deepest cut of Sicks' Stadium baseball history.
• For Father's Day, Black History Month, or Juneteenth: The Steelheads carry a meaning that generic team gear doesn't. Pacific Northwest Black baseball heritage as a tribute, not a generic purchase.
• Year-round demand. Steelheads nostalgia is not seasonal.

The 1946 Negro West Coast Baseball League — A Single Ambitious Summer

The Negro West Coast Baseball League was organized in winter 1945–46 as the Pacific Coast counterpart to the established Negro National League (Eastern) and Negro American League (Midwestern/Southern). Six charter franchises represented the major West Coast cities: Seattle Steelheads (Sicks' Stadium), San Francisco Sea Lions, Oakland Larks, Los Angeles White Sox, Portland Rosebuds (Vaughn Street Park), and San Diego Tigers. A seventh franchise, the Fresno Tigers, played as a traveling team without a fixed home field.

The league's economic model was based on three premises: (1) the post-WWII Pacific Coast had a rapidly growing Black population, particularly in the San Francisco Bay Area, Los Angeles, Seattle, and Portland; (2) major-league-quality ballparks were available in most of those cities through partnerships with the existing PCL franchises; and (3) NLB veterans were eager for full-season Pacific Coast play. All three premises were correct.

What the league did not account for was the timing of MLB integration. Jackie Robinson had signed with the Brooklyn Dodgers organization in October 1945, started his Montreal Royals season in spring 1946, and was a national story by midsummer. Black baseball talent that might have anchored a Negro West Coast League instead waited for MLB calls. Several NLB stars who had committed to West Coast teams broke their contracts in midseason to pursue MLB opportunities. By August 1946 the league was hemorrhaging talent and money.

The Negro West Coast Baseball League folded after the 1946 season. The Steelheads, Sea Lions, Oakland Larks, and other franchises ceased competitive operations. Some of the rosters reformed as barnstorming squads; some players moved to the established Negro Leagues in the East and Midwest; some signed minor-league or independent contracts and waited for MLB integration to expand. By 1947, organized West Coast Negro Leagues baseball had ended.

The legacy of the 1946 NWCBL is in what it tried to do, not what it accomplished. It demonstrated that Pacific Coast Black baseball had real fan demand, real player talent, and real cultural infrastructure to support full-season organized play. That demonstration helped accelerate the integration of MLB's Pacific Coast affiliates and the eventual creation of MLB franchises in San Francisco (1958), Los Angeles (1958), Oakland (1968), San Diego (1969), and Seattle (1969 and 1977).

Abe Saperstein — The Steelheads' Owner and Black Sports Promoter

Abe Saperstein owned the Seattle Steelheads. By the time the Steelheads launched in 1946, Saperstein had already built the Harlem Globetrotters into one of the most successful sports entertainment franchises in American history, having founded the Globetrotters in 1926 in Chicago.

Saperstein's relationship to Black sports was complicated. He was a Jewish-American immigrant from London (born 1902) whose family had moved to Chicago. He saw Black athletic talent both as legitimately under-represented in mainstream American sports and as a major commercial opportunity that mainstream owners were ignoring. He built the Globetrotters into a touring entertainment franchise that played hundreds of games per year against white opposition, won most of them, and became one of the most popular sports operations in America.

His baseball ventures included partnerships with the Birmingham Black Barons (where he held an ownership stake during the 1948 Willie Mays years) and the Seattle Steelheads (which he financed through 1946). Both ventures were less successful than the Globetrotters; both reflected Saperstein's belief that integrated baseball entertainment had an audience.

Saperstein died in 1966. The Globetrotters continue to operate today. The Steelheads jersey he financed is now a piece of Pacific Northwest sports history — owned by one of the most successful Black sports entrepreneurs of the 20th century, even if he himself was not Black.

Sicks' Stadium — Where the Steelheads Played

The Steelheads played their home games at Sicks' Stadium, located in Seattle's Rainier Valley at the corner of Rainier Avenue and McClellan Street. Built in 1938 as the home of the Pacific Coast League's Seattle Rainiers, Sicks' Stadium was a major-league-quality minor league ballpark with a seating capacity of 11,000.

The stadium was named for Emil Sick, owner of the Seattle Rainiers and Sicks' Brewery, the family business that produced Rainier Beer. Sick was a Pacific Northwest sports philanthropist who funded both the Rainiers and various amateur baseball programs in the Seattle area.

Sicks' Stadium's most famous chapter came not from the Steelheads but from the 1969 Seattle Pilots, the single-season MLB franchise that played its home games there before relocating to Milwaukee for 1970. The Pilots' brief Sicks' Stadium tenure inspired Jim Bouton's Ball Four, one of the most influential baseball books ever written.

Sicks' Stadium was demolished in 1979. The site is today a Lowe's home improvement store at the corner of Rainier and McClellan. A historical marker commemorates the Rainiers' and Pilots' tenure there; the Steelheads' single-season chapter is not formally marked but is part of the site's documented history.

How to Identify Authentic Steelheads Throwback Apparel

Authentic Seattle Steelheads throwback gear is genuinely difficult to source — the Steelheads played one season, the visual archive is limited to a handful of surviving photographs, and most "vintage baseball" retailers ignore the Pacific Coast Negro Leagues entirely. Royal Retros is one of the few specialty retailers carrying Steelheads gear at retail. Here's how to evaluate any Steelheads-era piece:

• Check the team-specific design. The Steelheads wore "Steelheads" wordmark home jerseys with a Pacific Northwest color palette in the 1946 NWCBL season. Authentic throwback gear matches the limited surviving reference imagery.
• Verify period-correct construction. 1940s baseball jerseys used wool flannel with twill or felt lettering, not modern synthetic fabrics. A "vintage" Steelheads jersey on synthetic fabric is a modern remix or reproduction piece — fine to buy, but not historically accurate construction.
• Check the team color palette. The Steelheads' colors are documented from contemporary newspaper accounts and a small number of surviving uniform fragments. We work from those sources for our color reproduction.
• For customization: Period-correct numbering used a specific block-or-script font family. We use that family on our custom jerseys.
• Royal Retros standard: Every product in this collection is reviewed for period accuracy before it goes live.

More Frequently Asked Questions About the Seattle Steelheads

Who were the Seattle Steelheads?

The Seattle Steelheads were a 1946 charter franchise of the Negro West Coast Baseball League — a short-lived Pacific Coast counterpart to the established Negro National League and Negro American League. The Steelheads played one season at Sicks' Stadium in Seattle. The league folded after the 1946 season due to operational pressures and the acceleration of MLB integration.

Who owned the Seattle Steelheads?

Abe Saperstein, the founder and owner of the Harlem Globetrotters basketball franchise, owned the Steelheads. Saperstein was a Chicago-based Jewish-American sports promoter who built multiple Black sports ventures in the 1930s, 1940s, and 1950s.

Where did the Seattle Steelheads play their home games?

Sicks' Stadium in Seattle's Rainier Valley, located at the corner of Rainier Avenue and McClellan Street. Sicks' Stadium also hosted the Pacific Coast League's Seattle Rainiers (1938–1968) and the single-season Seattle Pilots MLB franchise (1969). The stadium was demolished in 1979.

Did the Seattle Steelheads ever win a championship?

No formal championship — the 1946 NWCBL season was disrupted enough by talent departures and financial pressures that the league did not stage a formal championship round.

Why did the Negro West Coast Baseball League fail?

Three primary reasons: (1) Jackie Robinson's signing with the Brooklyn Dodgers organization in fall 1945 accelerated MLB integration in spring 1946, drawing Black baseball talent toward MLB opportunities rather than independent Negro League play; (2) the league's financial model assumed steady fan attendance that didn't materialize at sustainable levels in all six markets; (3) operational pressures — travel costs, scheduling against PCL home games, ballpark availability — were higher than projected. The league folded after one season.
