Peng Cheng-min

During the 2001–02 seasons he was designated hitter for the team, as he was picked 1st overall in the 2001 draft. Starting in 2003, he began his four-season tenure in right field after adjusting to the role. However, in the middle of the 2006 season Brother Elephants released then first baseman Tsai Feng-an (蔡豐安) and Peng switched to play first base, late in his career, he also played as an occasional designated hitter. He also wore number 23 because his original number 6 jersey was worn by Tsai when he first entered the team, but he never reverted back to the number, as there had been no notable players who wore number 23 in baseball.

He is known for his skill hitting inside-out, so he always lands the ball on the right side of the field, that falsely listed him as an opposite-field hitter. He has won five CPBL Batting Championship Awards and holds the Chinese Professional Baseball League records for career Singles(1515), walks (1126), and runs scored (1090). he was the pivotal and the only member of both generations of Three Slugging Muketeers.

However, in 2005, he had an incident similar to David Ortiz, where he hit a power box out of frustration. That caused him to inflict multiple fractures on his wrist. He missed the 2005 calendar year, and the top half of 2006 season. The break included all of the international fixtures, including Intercontinental Cup 2006.

In 2008, he hit .391, a CPBL single-season record.(Then it was broken by Wang Po-jung with .414 in 2016) On 20 September 2008, Peng hit the 1000th home run in Elephant's history, and followed it up on 28 March 2009 with the CPBL's 6000th home run. He recorded his career 1,000 hits on 18 August 2010 in Taichung Baseball Field, becoming the player reached the 1,000 hits with fewest games(844), plates (3469), at bats (2838).

In the end of 2010, when the Brother Elephants seized the championship, he gained the CPBL MVP of the Year Award, adding to the one earned in 2001, and also adding to his three consecutive titles.

On 21 November 2011, Peng signed a ten-year extension with the Brother Elephants, five-year as player and five-year as coach. The contract worth 66 million NT dollar (roughly 2.27 million US dollar), it is the largest contract for a player in CPBL history.

Since 2012, however, he was no longer a regular starter. After becoming the 4th player in CPBL history to reach 1000 hits, 100 home runs and 100 steals landmark, it wasn't until May 4, 2014, where he made his 200th stolen base, and made hit 2000th base hit on July 7, 2019. 10 days later, he became the highest ever run scorer, 1076 runs scored.

In January 2019, Peng announced his retirement from baseball, and will play his final match on September 29 as a testimonial match, with his jersey number likely to be retired at the conclusion of the match. During the final week, all team members wore the jersey with 'Chia, 23' on their back. His actual final match was in the Final when the team lost 3-20, which incidentally adds to 23, his shirt number.

He became an assistant batting coach for Chinese Taipei National Team in October, 2019.
