[1] The team temporarily moved to southern Arizona and became the Tucson Padres while awaiting a new purpose-built stadium in their planned future home of Escondido, California.

[5] A team in the Pacific Northwest League was formed called the Portland Green Gages, which folded early in its first season.

His obituary later read that the ballpark was "the sensation of baseball, because it inaugurated a minor league precedent of providing individual grandstand seats, which fellow magnates called an extravagance and a dangerous innovation."

The NAPBL made a change to league classifications in 1912, making Double-A the top tier.

The PCL, and the Portland Beavers, moved into this new classification from the previous top tier Class A league.

Though the 1915 Beavers featured future Hall of Famer Stan Coveleski, the team did not fare too well, and started into a tailspin that would last for over a decade.

With America's entry into World War I, restrictions were placed on travel, such that the Beavers withdrew from the PCL for the 1918 season, playing instead in the Class B Pacific Coast International League.

The team was known as the Portland Buckaroos and finished their shortened season (play was stopped on July 7 due to the war) in second place 1½ games back of Seattle.

Klepper brought in the 35-year old Jim Thorpe, who played outfield and first base with the Beavers in 1922,[9] paying him a then-unheard of minor league salary of US$1,000 per month.

Landis suspended Klepper until January 1, 1925, and declared Kenworthy ineligible to play or manage Portland until 1924.

[10] According to The Portland Beavers, a book by Kip Carlson and Paul Andresen, "The feisty Klepper went to court and had the decision overturned, supposedly the only time that Landis ever had a ruling reversed."

Despite having Duffy Lewis on the team in 1925 (winning the PCL batting title), Elmer Smith in 1926 and 1927 (leading the PCL in home runs in 1926 and all of minor league baseball in home runs in 1927), and Ike Boone in 1928, the Beavers continued to finish in the bottom half of the league.

The highlight of the Beavers last place 1930 season was William Rhiel's unassisted triple play, the last recorded in PCL history.

Ed Coleman led the PCL in hits and runs batted in, and the team finished in third, winning 100 games.

In 1943, William Klepper, with partner George Norgan buying a minority share, purchased the Beavers.

Oregon Governor Earl Snell presented a commemorative watch and gold and diamond ring to each player at the banquet.

The watches were given to the players due to L. H. Gregory of The Oregonian requesting fans to donate money to a fund for the purpose.

In 1946, the Beavers fell to the bottom half of the league, finishing in seventh place, 41 games out of first.

The 1949 season began the integration of the Pacific Coast League as Frankie Austin and Luis Marquez became Beavers.

Throughout most of the 1960s, the Beavers were the Triple-A affiliate of the American League Cleveland Indians, nurturing such future stars as "Sudden" Sam McDowell, Lou "Mad Dog" Piniella, and Luis "El Gigante" Tiant.

The PCL expanded in 1978 and added a new team in Portland, calling themselves the Beavers, displacing the single-A Mavericks.

[14][15] As PCL champs in 1983, the Beavers participated in the first Triple-A World Series, a three-team round-robin competition in Louisville with the champions of the International League and the American Association.

[20] Following the 2000 season, the Los Angeles Dodgers and San Diego Padres swapped Triple-A affiliates.

The single-A Portland Rockies moved up the Columbia River to Pasco and became the Tri-City Dust Devils in 2001.

The team also brought back the name "Lucky Beavers" as part of a sleeve patch on their alternate jersey.

[25] Initial plans called for the new ballpark to be built at the site currently occupied by the Memorial Coliseum, which would have been torn down,[26] but public outcry about demolishing a Portland landmark led Portland mayor Sam Adams to propose a second site in the Rose Quarter area north of Memorial Coliseum.

[27] Another location on the site of Charles D. Walker Stadium in the Lents neighborhood in southeast Portland was also rejected due to objections from neighbors.

[28] That was until the Portland Pickles collegiate wood bat team began play in 2016 at Walker Stadium.

With no suitable Portland location available, in July 2010, Paulson announced that he was putting the team up for sale and relocation.

[35] The plans in Escondido failed, and the team was sold again; they moved to west Texas prior to the 2014 season and became the El Paso Chihuahuas.
