1904–1905: Tacoma Tigers Tacoma's first team in the PCL was the
Tacoma Tigers, who joined the league in 1904, having moved from
Sacramento after the 1903 season. The 1904 Tigers won Tacoma's first PCL pennant, finishing first in both halves of the split season schedule, seven games (annualized) over the runner-up Los Angeles Angels. The 1905 Tigers won the first-half championship, then lost the postseason series to the Angels. After the season owner Mike Fisher relocated the team as the
Fresno Raisin Eaters. The PCL did not return to Tacoma for 55 years; however, another Tacoma Tigers franchise operated in the
Western International League from the 1930s through 1951. Owned by William Starr of
San Diego, they were affiliated with the
San Diego Padres of the PCL. The team was sold, relocated to
north central Idaho, and became the
Lewiston Broncs in 1952.
1960–1965: Tacoma Giants The current PCL franchise was founded in 1960 when the
Phoenix Giants, a
San Francisco Giants affiliate, moved to Tacoma and became the Tacoma Giants, the first team to play at brand-new
Cheney Stadium. The Giants' first win at Cheney Stadium came on April 16, 1960—an 11-0 victory over Portland in game two of a doubleheader. Future
Hall Of Fame pitcher
Juan Marichal worked the victory, giving Tacoma their first franchise shutout performance. The 1961 iteration of the club posted a 97–57 record under manager Red Davis, who steered a team led by
Gaylord Perry,
Ron Herbel,
Eddie Fisher, and
Dick Phillips. Following a season in which he hit .264 with 16 home runs and 98 RBI, Phillips was named the 1961
PCL Most Valuable Player (MVP). The franchise did not have another MVP winner until
José Marmolejos in 2021.
1966–1971: Tacoma Cubs In 1965, the Giants moved its PCL team back to Phoenix. However, the
Chicago Cubs chose to move their affiliate, the
Salt Lake City Bees, to Tacoma the same year and renamed the team the Tacoma Cubs. Tacoma played as a Cubs affiliate for six seasons, compiling a record. The Tacoma Cubs were managed by Whitey Lockman for their first four seasons, including a 1969 PCL Championship after finishing the year 86–60. The 1969 Cubs pitching staff compiled a 3.01 team ERA, and bested Eugene for the league championship 3–2 in a best-of-five series.
1972–1977: Tacoma Twins Following the 1971 season, the Cubs left town. Local businessmen Stan Naccarato and Clay Huntington spearheaded a group of local investors who purchased the franchise and secured an affiliation with the
Minnesota Twins, who renamed the team the Tacoma Twins. The new local ownership team, known as the Tacoma Twins Baseball Club Directors, comprised the following: E.J. Zarelli (President); Stan Naccarato (General Manager-Vice President); Frank Manley (Treasurer); Tom Baker (Secretary); and Clay Huntington, Alden Woodworth, Francis Browne, Robert Alessandro, Mike Tucci Jr., Walt Wiklund, Dr. Robert Johnson, Lawrence Ghilarducci Sr., James Topping, Marley Brotman, Carl Miraldi, Frank Ruffo, Douglas Goneya, Ray Carlson, Frank Pupo, Bill Cammarano Sr., and Mike Block (Vice Presidents). Through six seasons as a Twins affiliate, Tacoma compiled a record with no league championships. During the Twins era, infielder
Rick Renick (1973–76) slugged his way to 72 home runs, giving him the most career home runs in franchise history. In the midst of a 1977 season in which he hit .321 with 25 home runs and 117 RBI, first baseman
Randy Bass notched four home runs on June 9, 1977 at Phoenix. Bass is one of only six players in PCL history to hit four or more home runs in one game. Future
Toronto Blue Jays broadcaster
Jerry Howarth broadcast games for Tacoma during this period.
1978: Tacoma Yankees For one season, the Tacoma franchise was affiliated with the
New York Yankees. As the Yankees compiled a 100-win
1978 season that culminated in an
American League East title over the
Boston Red Sox, the Tacoma Yankees compiled an 80–57 record and advanced to the league championship. The 1978 PCL championship series with
Albuquerque was cancelled due to rain, so Tacoma and Albuquerque were named PCL co-champions.
1979 Tacoma Tugs and 1980 Tacoma Tigers Following an affiliation change to the
Cleveland Indians, a local contest was held and long-time Tacoma resident, Gary Grip won with his entry, the Tacoma Tugs. Grip drew his inspiration for the name from the many tugboats in the Tacoma waters. The franchise was renamed the Tacoma Tugs, marking the first time the team's nickname did not align with its major league club. After one season as the Tugs, the team returned to the Tigers nickname in 1980. The team finished with nearly identical records in both years as a Cleveland affiliate, going 74–73 in 1979, and 74–74 in 1980.
1981–1994: Tacoma Tigers Following their brief stints with the Yankees and Indians, the team changed their affiliation to the Oakland A's, a partnership that lasted fourteen seasons. While the affiliation with Oakland provided five playoffs appearances for Tacoma fans, it produced no league champions. Future American League
Rookies of the Year Walt Weiss,
Jose Canseco, and
Mark McGwire all played in Tacoma during this period.
Scott Brosius, Tacoma's future hitting coach, also played for Tacoma during the Oakland era.
1995–present: Tacoma Rainiers The team affiliated with the nearby
Seattle Mariners in
1995, whose Triple-A team for the previous ten seasons had been the
Calgary Cannons. On November 3, 1994, Tacoma adopted the Rainiers name in part as a tribute to the
Seattle Rainiers minor league teams that played from 1938 to 1964 in the PCL and again from 1972 to 1976 in the
Northwest League (NWL). Since their affiliation began with the Mariners in 1995, nearly all of the organization's homegrown prospects have passed through Tacoma, including
Alex Rodriguez,
Raúl Ibañez,
Félix Hernández,
J. J. Putz,
Kyle Seager,
Ken Griffey Jr. (on rehab assignments), and more. Tacoma was managed by
Dan Rohn from 2001 to 2005, a three-time PCL Manager of the Year Award recipient. Under Rohn's direction, the Rainiers compiled a record. The Tacoma Rainiers shared the 2001 PCL championship with New Orleans after the
September 11 attacks forced the cancellation of the championship series. The Rainiers advanced to the championship series in 2005 but were swept by the
Nashville Sounds. The Tacoma Rainiers won its second PCL championship in 2010. The Rainiers are broadcast on
KIXI 880 AM with radio play-by-play also streamed online.
Rylee Pay became the team's play-by-play announcer in 2025, making her the first female lead broadcaster in Triple-A baseball, and replacing Mike Curto, who had been with the team since 1999 and retired in 2024. The team had an internet-only radio broadcast from 2021 to 2023 and previously was broadcast on
KHHO 850 AM. In conjunction with
Major League Baseball's restructuring of Minor League Baseball in 2021, the Rainiers were organized into the
Triple-A West. Tacoma ended the season as champions of the Western Division by finishing in first place with a 73–47 record. No playoffs were held to determine a league champion; instead the Rainiers also won the Triple-A West championship by having the best regular-season record among all 10 teams. However, 10 games that had been postponed from the start of the season were reinserted into the schedule as a postseason tournament called the Triple-A Final Stretch, in which all 30 Triple-A clubs competed for the highest winning percentage.
José Marmolejos won the
Triple-A West MVP award that season. The Rainiers set a new PCL record in 2024 with 286 stolen bases, surpassing the 1981
Albuquerque Dukes' 281 steals. ==Season-by-season records==
