Si-Yo Wu was one of many Taiwanese stars whose careers ended in a gambling scandal.
Wu debuted in Taiwan for the 2004 La New Bears, going 5-4 with a 2.84 ERA and 80 strikeouts in 73 innings at age 22. On September 28, he was timed at 152 kmph (94.4 mph), then a record for a native hurler. In '05, he had a 7-6, 3.54 record. He had his best campaign in 2006 when he went 17-3 with a 2.27 ERA and 142 strikeouts in 139 innings. He tied En-Yu Lin for the CPBL lead in wins.
Wu played for the Bears in the 2006 Asia Series and drew the interest of the Chiba Lotte Marines, who signed him. He spent all of 2007 in the minors and then allowed two runs in eight innings in 2008.
Let go by the Marines, Wu re-signed with the Bears. He was on Taiwan's preliminary roster for the 2009 World Baseball Classic but did not make the final cut. He was not nearly as good as he was prior to his time in Japan, going 4-6 with a 5.37 ERA and 94 hits in 62 innings.
In early 2010, Wu was banned from the CPBL due to his involvement in game-throwing scandals with the Bears.
