The new scandal broke less than a day after the Uni-President 7-Eleven Lions defeated the Brother Elephants 5-2 to win Taiwan’s professional baseball championships title for the third year in a row.

Tsao, now a member of the Elephants, played for the Colorado Rockies as the first-ever Taiwanese pitcher to play an MLB game and the first Taiwanese player to get a hit. After serving with the Rockies from 2003 to 2005, he pitched for the Los Angeles Dodgers in 2007.

Investigators visited his house early Monday and he had been listed with five other Elephants players for questioning on Wednesday, team chief Hung Juei-ho told a news conference.

Tsao pleaded his innocence, Hung said, who said he believed the star. The pitcher later issued a statement expressing his “anger and disappointment” in being accused of game fixing less than a year after returning from the U.S. to play for a Taiwanese team.

Hung said prosecutors should not search players’ homes without any evidence of wrongdoing. In addition to star pitcher Tsao, investigators would also question Elephants players Liu Yu-chan, Wu Pao-chien, Wang Ching-li, Wang Chun-tai and Lee Hau-jen, Hung said. Last year, the team chief said that if any of his players were involved in game fixing, he would disband the team.

Early reports Monday said the Banciao Prosecutors Office questioned 11 people involved in running the gambling scam and three witnesses, including current players, reports said. The brain behind the scheme, a man surnamed Tsai, was reportedly arrested at his home in Kaohsiung at 6 a.m. Monday. A former Elephants trainer allegedly played the part of general coordinator for the gambling syndicate.

Prosecutors said they searched 29 locations across the whole country, including baseball players’ dormitories, but they would not reveal the identities of the suspected players as most of them had not been questioned yet.

One former member of the Elephants played the role of general supervisor in the whole scam, media reports said. Speculation in the media indicated the scandal might involve Taiwanese and foreign players, as well as local players recently returned from the United States.

Prosecutors reportedly first found evidence of the new game-fixing plot last year during their investigations into the scandal involving the dmedia T-Rex team, the Chinese-language United Evening News said Monday.

The new group was the largest of five groups involved in game-fixing and had close ties to a major organized crime gang, the paper said.

Prosecutors reportedly struck so soon after Sunday’s game because they feared the leaders behind the scheme would travel to China, as game fixers did on previous occasions.

Taiwanese baseball has suffered from game-fixing scandals for more than a decade. Apart from the Elephants and the Lions, the Chinese Professional Baseball League has only two other teams left, the Sinon Bulls and the La New Bears.
