Jang Sung-woo

Jang Seong-woo (born January 17, 1990) is the catcher of KT Wiz of the KBO League. He joined Lotte Giants in 2008. After that, he belonged to Korean Police Baseball Team in 2012, and he moved to Lotte Giants again in 2014. Then he moved to KT Wiz in 2015. He won the most RBI in the North Korean league in the Yakult Seven Pro Baseball Futures League in 2013. He graduated from Kyungnam High School.

Controversy
After the 2015 season, his ex-girlfriend revealed his personal life, saying that Park Ki-ryang, a cheerleader for the Lotte Giants, was suing him and had no intention of reaching an agreement.

In the end, the club suspended him for 50 games and disciplined him for his volunteer work, making him unable to play in the early part of the 2016 season. In addition, back pain remained, so he ended the season without making it to the first division in 2016.
