Joey Hamilton, a right-handed pitcher, entered Major League Baseball with a promising start. Born on September 9, 1970, in Statesboro, Georgia, Hamilton attended Georgia Southern University, where he honed his skills on the mound. His talent caught the attention of scouts, and he was selected by the San Diego Padres as the eighth overall pick in the first round of the 1991 MLB Draft.

Hamilton made his MLB debut with the Padres on May 24, 1994. In his rookie season, he quickly established himself as a reliable starter, finishing with a 9-6 record and a 2.69 ERA over 22 starts. His performance earned him a spot on the Baseball Digest All-Rookie Team, signaling a bright future ahead.

Over the next few years, Hamilton remained a steady presence in the Padres' rotation. In 1996, he achieved a career-high 15 wins, helping the Padres secure the National League West division title. That season, he posted a 15-9 record with a 4.17 ERA, and his efforts were instrumental in the Padres' postseason run. Although the team was swept by the St. Louis Cardinals in the National League Division Series, Hamilton's contributions were vital to their success that year.

In 1998, Hamilton was traded to the Toronto Blue Jays, where he continued to be a dependable starter. During his tenure with the Blue Jays, he faced challenges with injuries, which affected his performance. Despite these setbacks, he managed to compile a 6-7 record with a 4.27 ERA in his first season with the team.

Hamilton's time in Toronto was followed by a stint with the Cincinnati Reds, beginning in 2000. While with the Reds, he transitioned to a role that included both starting and relieving, adapting to the team's needs. His versatility on the mound was evident as he worked to maintain his effectiveness despite the changes in his role.

In 2002, Hamilton signed with the Florida Marlins, where he spent the final two seasons of his MLB career. During this period, he continued to contribute as a pitcher, though his appearances became less frequent. He retired from professional baseball after the 2003 season, concluding a career that spanned a decade in the major leagues.
