Chan Ho Park, a trailblazer for Asian athletes in Major League Baseball (MLB), embarked on his professional journey with the Los Angeles Dodgers. Born in Gongju, South Korea, Park became the first South Korean to play in the MLB, breaking new ground for players from his country. His debut came on April 8, 1994, when he took the mound for the Dodgers, marking the beginning of a career that would span nearly two decades.

Park's early years with the Dodgers were a period of adjustment as he adapted to the rigors of American baseball. By 1996, he began to find his footing, showcasing his potential as a starting pitcher. The 1997 season was a breakout year for Park, as he recorded 14 wins and established himself as a reliable presence in the Dodgers' rotation. His performance continued to improve, and in 1998, he achieved a career-high 15 wins, further solidifying his role as a key player for the team.

The pinnacle of Park's career with the Dodgers came in 2000, when he was selected for the MLB All-Star Game. That season, he posted an impressive 18-10 record with a 3.27 ERA, earning recognition as one of the league's top pitchers. Park's success on the mound was characterized by his powerful fastball and effective slider, which kept opposing batters off balance.

In 2002, Park signed a lucrative contract with the Texas Rangers, a move that was met with high expectations. However, his tenure with the Rangers was marred by injuries and inconsistency. Despite these challenges, Park continued to demonstrate flashes of his earlier brilliance, but he struggled to replicate his success from his time with the Dodgers.

After stints with the San Diego Padres and a brief return to the Dodgers, Park found a new opportunity with the New York Mets in 2007. His time with the Mets was short-lived, and he soon joined the Los Angeles Dodgers once again. In 2008, Park transitioned to a relief role, where he found renewed success. His adaptability and experience proved valuable, and he became an integral part of the Dodgers' bullpen.

The Philadelphia Phillies signed Park in 2009, where he continued to excel as a reliever. His contributions helped the Phillies reach the World Series that year, although they ultimately fell to the New York Yankees. Park's performance in the postseason was commendable, as he provided stability and depth to the Phillies' pitching staff.

In 2010, Park joined the New York Yankees, adding another chapter to his MLB career. He later moved to the Pittsburgh Pirates, where he achieved a personal milestone by becoming the winningest Asian-born pitcher in MLB history, surpassing Hideo Nomo's record of 123 wins.

Chan Ho Park's career in Major League Baseball concluded with a brief stint with the Orix Buffaloes in Japan's Nippon Professional Baseball (NPB) in 2011.
