Jimmy Haynes, a right-handed pitcher, spent several years in Major League Baseball, showcasing his skills on the mound for various teams. Born on September 5, 1972, in LaGrange, Georgia, Haynes was drafted by the Baltimore Orioles in the seventh round of the 1991 MLB Draft. He made his major league debut with the Orioles on September 13, 1995.

Haynes' early years in the majors were marked by his time with the Orioles, where he played until 1996. His tenure with Baltimore was brief, and he was traded to the Oakland Athletics in 1997. With the Athletics, Haynes began to see more playing time, appearing in 30 games during the 1998 season. His performance with Oakland was a mix of ups and downs, as he worked to establish himself as a reliable starting pitcher.

In 1999, Haynes was traded to the Milwaukee Brewers, where he spent the next few seasons. It was with the Brewers that he began to find more consistency in his game. During the 2000 season, Haynes pitched in 33 games, starting 32 of them, and recorded a 4.12 ERA, which was one of the better performances of his career. His time with the Brewers allowed him to develop further as a pitcher, although he continued to face challenges with maintaining a low ERA.

Haynes' journey continued as he joined the Cincinnati Reds in 2002. His first season with the Reds was arguably his best in the majors. He achieved a career-high 15 wins and maintained a 4.12 ERA over 34 starts. This performance was a highlight in Haynes' career, as he demonstrated his ability to be a dependable part of the Reds' starting rotation.

However, the following seasons were less favorable for Haynes. In 2003, he struggled to replicate his previous success, finishing the season with a 2-12 record and a 6.30 ERA. The challenges he faced on the mound led to his release from the Reds in 2004. Shortly thereafter, Haynes signed with the Tampa Bay Devil Rays, but his time with the team was short-lived, as he was released after only a few appearances.

Throughout his career, Haynes was known for his fastball and his ability to pitch deep into games when he was at his best. Despite the fluctuations in his performance, he remained a part of the major league landscape for nearly a decade. His career statistics include a win-loss record of 63-89, an ERA of 5.37, and 754 strikeouts.
