Baseball was first introduced to Taiwan during
Japanese rule, and gained popularity when the national little league baseball teams won numerous
Little League World Series championships in the 1970s and 1980s. The
national baseball team also performed exceptionally well in many international competitions. He formed his amateur Brother Hotel baseball team in 1984, and intended to professionalize his team and form a professional league within a few years. Throughout 1988 and 1989, Hung visited numerous Taiwanese businesses, trying to convince them to form professional baseball clubs. Most of his requests were rejected, but the Wei Chuan Corporation, Mercuries Chain Stores, and
Uni-President Corporation all supported the idea and formed teams. The Chinese Professional Baseball League was established on October 23, 1989, with Hung Teng-sheng acting as secretary-general. Because of his contribution to professional baseball in Taiwan, Hung is sometimes referred to as the "Father of the CPBL."
Expansions in the 1990s With the popularity rise in the first few years, the
Jungo Bears and
China Times Eagles joined in 1993. The
Koos Group Whales joined in 1997. The CPBL consisted of seven teams in the 1997 season, the most in the league's history. However, at the same time,
TVBS and Sampo Corporation (聲寶企業) founded another professional baseball league,
Taiwan Major League. TVBS is ex-broadcaster of CPBL. Sampo Giants had been requesting to join the CPBL since 1992, but was repeatedly rejected by the CPBL for unexplained reasons. Despite there were eleven teams playing professional baseball, the two leagues
competed with each other.
Multi-impact, decline in popularity Game-fixing scandals, the Black Tigers Incident in 1995, and the Black Eagles Incident in 1997, resulted in a major popularity decline. The
China Times Eagles became defunct after the 1997 season. In the 1999 season, due to the
921 earthquake, the CPBL regular season was not fully finished. After the 1999 season, the
Wei Chuan Dragons and
Mercuries Tigers also became defunct, prior to which the Dragons had made a dynasty with three consecutive championships. In the 2000 season, the CPBL was reduced to four teams.
Merger with Taiwan Major League After the 2002 season, before the CPBL's 2003 season started, the TML finally agreed to merge with the CPBL. Four teams from TML reorganized to two and exchanged the team names. First Financial Holdings purchased
one of the teams, while Macoto Bank voluntarily took over
the other.
Game-fixing scandals Although the clash of leagues was solved, the game-fixing scandals still haunted baseball in Taiwan: the Black Bears Incident in 2005, the Black Whales Incident in 2007, the Black Dmedia Scandal in 2008, and the Black Elephants Incident in 2009. In October 2008, the Black Dmedia Scandal broke out. This was the first time gangsters directly controlled a baseball team for game-fixing. Eventually, Dmedia T-REX were expelled from the league. After the 2008 season, the
Chinatrust Whales became defunct and the league was reduced to four teams once again. After the 2009 season, the next day of
Uni-President 7-Eleven Lions made a dynasty (championships from 2007 to 2009), the Black Elephants Incident broke out. Brother Elephants was affected deeply by a match fixing scandal involving relief pitcher
Wu Pao-hsien which resulted in expulsion of many team players and the coach.
Big Companies take over At the end of the 2012 season, Sinon Corporation announced its intention to sell the team. By late December, an agreement was reached between Sinon Corporation and E-United Group, and the team was renamed EDA Rhinos after E-DA World, a large shopping, entertainment and hotel complex in Kaohsiung operated by E-United Group. The EDA Rhinos intends to play games at both Li De Baseball Stadium in downtown Kaohsiung and Chengcing Lake Baseball Field in the suburb during the upcoming 2013 CPBL season. The Rhinos also signaled in signing
Manny Ramirez for 2013 as its billboard player. Taiwanese former MLB player
Chin-lung Hu also signed with the team following the 2013 CPBL Draft. In October 2013, Brother Hotel announced attempts to sell the baseball team. The announcement drew interest from seven potential bidders. Brother Elephants was sold to Hua Yi, a subdivision of
CTBC Holding, by December 2013 for a price of NT$400 million. The team's name changed into
CTBC Brothers, reflected their new corporate parent, but it was felt that the branding from their previous owners was strong enough to rename the team Brothers, while retaining the elephant mascot. In June 2016, it was announced that the E-United Group are willing to sell the team. EDA Rhinos won the second stage of the 2016 CPBL season and qualified to the Taiwan Series, where they defeated CTBC Brothers 4–2 to win their first championship since 2005. In November 2016, the team was renamed as Fubon Guardians after
Fubon Financial Holding Co. bought the team.
Recent expansions In May 2019, Commissioner
John Wu announced that CPBL had reached agreement with
Ting Hsin International Group to join the league by reactivating a former team, the Wei Chuan Dragons. The Dragons participated in the minor league in 2020, and returned to the major league in 2021. After
Tsai Chi-chang became commissioner in 2021, he proposed that
Kaohsiung serve as the location for a new team since it was the only
major city in Taiwan without a CPBL team at the time. In February 2022, Tsai announced that the sixth team would be formed by either
Chunghwa Telecom or
Taiwan Steel Group; it was later announced that the expansion team would be owned by Taiwan Steel Group, and that the team would be named
TSG Hawks, with their home field at
Chengcing Lake Stadium in Kaohsiung.
2020 season and COVID-19 Due to the
COVID-19 pandemic, the opening day of the
31st CPBL season on March 14 was delayed. It was originally brought earlier compared to previous seasons to accommodate the
final qualifying tournament of
2021 Tokyo Olympics. On 1 April, the CPBL announced that the season would begin from 11 April as the
Rakuten Monkeys hosted the CTBC Brothers with the games being playing without live fans. This received international coverage because other major baseball leagues such as the
MLB in North America, the
NPB in Japan, and the
KBO in South Korea, which were still severely impacted by the virus outbreak were unable to confirm the dates of their respective season openings. The annual
CPBL All-Star Game was cancelled for the first time to accommodate to the compact schedule.
After the 2020 season In 2025, Sarah Edwards became the first female on-field coach in Asian professional baseball, as a hitting coach for the
CTBC Brothers in the CPBL. ==Naming issue==
