Alfredo Amezaga, a professional baseball player from Mexico, spent several years in Major League Baseball (MLB) showcasing his skills as a utility player. Born on January 16, 1978, in Ciudad Obregón, Sonora, Amezaga's journey to the major leagues began when he was drafted by the Anaheim Angels in the 13th round of the 1999 MLB Draft. His versatility on the field allowed him to play multiple positions, including shortstop, second base, third base, and all three outfield positions.

Amezaga made his MLB debut with the Anaheim Angels in 2002. During his time with the Angels, he was primarily used as a backup infielder and outfielder, providing depth to the roster. His ability to play various positions made him a valuable asset to the team, although he struggled to secure a permanent starting role. After spending parts of three seasons with the Angels, Amezaga was traded to the Colorado Rockies in 2005. His stint with the Rockies was brief, as he appeared in only a handful of games before being released.

In 2006, Amezaga signed with the Florida Marlins, where he found more consistent playing time. His tenure with the Marlins marked the most stable period of his MLB career. Amezaga's defensive flexibility allowed him to fill in wherever needed, and he became a regular fixture in the Marlins' lineup. Over the next few seasons, he played in various roles, often coming off the bench or starting in place of injured teammates. His batting average during his time with the Marlins hovered around the .250 mark, and he contributed with occasional stolen bases and runs scored.

Amezaga's time with the Marlins was interrupted by injuries, which limited his playing time in the later years. Despite these setbacks, he remained a reliable option for the team when healthy. In 2009, he underwent microfracture surgery on his knee, which sidelined him for the entire season. He attempted a comeback in 2010 but was released by the Marlins before the season began.

After leaving the Marlins, Amezaga continued to pursue his baseball career, signing minor league contracts with several teams, including the Los Angeles Dodgers and the Colorado Rockies. Although he did not make it back to the major leagues during these stints, he remained active in professional baseball, playing in the minor leagues and in international leagues.

Throughout his MLB career, Amezaga was known for his defensive capabilities and his ability to adapt to different positions on the field.
