Jesse Harrison Jefferson was a professional baseball player who had a significant career in Major League Baseball (MLB) as a right-handed pitcher. Born on March 3, 1949, in Midlothian, Virginia, Jefferson's professional career spanned over a decade, during which he played for several teams.

Jefferson began his MLB career with the Baltimore Orioles in 1973. He was part of the Orioles team that won the American League Championship in 1973 and 1974, although they did not secure the World Series title. Jefferson's tenure with the Orioles was marked by his strong pitching skills, but he was often overshadowed by other prominent players on the team.

In 1975, Jefferson was traded to the Chicago White Sox, where he spent two seasons. His time with the White Sox was marked by a significant increase in his playing time, and he became a regular starting pitcher for the team. However, despite his increased role, Jefferson struggled with consistency and was unable to replicate the success he had experienced with the Orioles.

Jefferson's career took a turn in 1977 when he was traded to the Toronto Blue Jays, an expansion team at the time. He was part of the inaugural Blue Jays team and made history by pitching the first complete game in the franchise's history. Jefferson spent four seasons with the Blue Jays, during which he established himself as a reliable starting pitcher.

In 1981, Jefferson moved to the Pittsburgh Pirates, where he spent a single season. His time with the Pirates was marked by a decline in his performance, and he was released by the team at the end of the season. Jefferson then signed with the California Angels, where he spent the final season of his career in 1981.

Throughout his career, Jefferson was known for his fastball and slider, which were his primary pitches. He was also known for his durability and his ability to pitch deep into games. However, despite his skills, Jefferson struggled with control and consistency, which often led to high earned run averages (ERAs) and a low winning percentage.

In total, Jefferson played in 387 games during his MLB career, starting 298 of them. He finished his career with a record of 39 wins and 81 losses, an ERA of 4.81, and 558 strikeouts. Despite his struggles, Jefferson's career was marked by moments of brilliance and he left a lasting impact on the teams he played for.

After retiring from professional baseball, Jefferson returned to his hometown in Virginia, where he worked as a truck driver and coached youth baseball. He passed away on September 8, 2011, at the age of 62. Despite the ups and downs of his career, Jesse Jefferson's contribution to Major League Baseball remains a significant part of the sport's history.
