Kuo Tai-yuan height - How tall is Kuo Tai-yuan?

On February 15, 2007, Kuo was appointed as the head coach of the Chinese Taipei national baseball team by the Chinese Taipei Baseball Association. His tasks included the 2007 Baseball World Cup and 2007 Asian Baseball Championships. However the Chinese Taipei national baseball team performed poorly in both tournaments and he was exempted from the post on December 15, 2007.

After retiring from Seibu Lions, the Taiwan Major League(TML) hired Kuo as "senior technical consultant" until the league's collapse in early 2003. Meantime he introduced his former Seibu teammates Takehiro Ishii and Hisanobu Watanabe to join TML, originally as players and later as coaches. He also acted as go-between to help then young Hsu Ming-Chieh and Chang Chih-chia join Seibu Lions, following his steps.

After a disappointing 2003 in which he was temporarily jobless and suffered marital crisis (as revealed in the "Personal Life" section later), in 2004 he started to head coach the Macoto Cobras until the end of 2005 season. During his 2 seasons with the Cobras Kuo accumulated a 93 wins, 97 losses, and 17 ties performance. In the 2005 Taiwan Series the Cobras were swept by the Sinon Bulls 0-4 and Kuo resigned right after the fiasco, addressing that "I would like to spend more time with my family". He later introduced Macoto Cobras players Lin En-yu and Lin Ying-Chieh to join Tohoku Rakuten Golden Eagles.

Kuo retired at the end of 1997 season after he suffered long time wound which cost him a vacant season. Shortly after Kuo's retirement a poll in the Seibu Lions' official website unanimously voted Kuo as the most popular international player in the Seibu Lions history.

Kuo married Taiwanese model and actress Chang Chiung-tzu (張瓊姿, also credited as Zhang Qiuzi by Chinese media) in December 1993. After their marriage, Chang temporarily gave up her acting career in Taiwan to live with Kuo in Japan until his retirement late in 1997. Together, they had 2 daughters, born in 1997 and 1999.

As a rookie, Kuo immediately gained a position in Seibu Lion's starting rotation and no-hit the Nippon Ham Fighters on June 4, 1985, less than 2 months after his debut, and is the first international player to achieve so in the Pacific League history. Kuo's other notable achievements during his NPB career included:

In the 1984 Olympics preliminary round against the United States, Kuo pitched up to 158 km/h (98 mph) and allowed only 2 runs (one earned run) during his complete game effort, earning the nickname "The Oriental Express". However, Chinese Taipei eventually lost to Team USA, which was studded with Will Clark, Mark McGwire, and the like. Kuo later pitched in the semifinal round against Japan, allowing one run in 4.2 innings. Kuo's excellent performance drew special attention from the Seibu Lions, and he signed with the club after the 1984 Summer Olympics.

Kuo was born in Tainan City, Taiwan. Originally a shortstop, he started to pitch in high school and immediately became well known for his high quality fastball and slider. In the 1983 Chinese Taipei versus South Korea match in Asian Baseball Championship, Kuo did not allow a run to score during 17 consecutive innings, while his fastballs clocked up to 154 km/h (96 mph). He finally won the game and helped Chinese Taipei qualify for the 1984 Summer Olympics.
