Yi-Cheng Tseng (formerly known as Chieh-Chih Tseng) is a pitcher for the Uni-President Lions.
Tseng pitched for the Taiwan national team while in college. He went 1-1 with a save and a 7.16 ERA in the 1999 World Port Tournament, striking out 12 in 7 1/3 innings. In the 1999 Intercontinental Cup, he had a save and a 4.26 ERA in 4 games, fanning 10 in 6 1/3 IP. He also appeared in the 1999 Asian Championship.
Tseng signed with the Uni-President Lions for 5 million NT (New Taiwan Dollars). At the time, it was a record signing amount for the Chinese Professional Baseball League to that point.
In 2000, Tseng was 0-1 with a 3.60 ERA in two games. He went 6-5 with a 3.76 ERA in 2001 (he had the first no-hitter to be cut short by rain in CPBL annals, June 13 against the Sinon Bulls), then 8-4 with a 5.55 ERA in a rough 2002 season. He was 0-1 with a 0.71 ERA in 2003, missing most of the year due to injury. He returned in 2004, going 3-2 with a 2.65 ERA. In 2005, Tseng was 1-1 with 11 saves and a 2.07 ERA. He had another fine year in '06 (2-1, 17 Sv, 2.17) and was named the reliever of the year; he tied for the most saves in the CPBL.
Tseng was 1-1 with a save and a 2.70 ERA in the 2007 CPBL. In 2008, he went 3-0 with 3 saves and a 2.97 ERA.
