Tomas Perez, a Venezuelan infielder, spent over a decade in Major League Baseball, known for his utility role across several teams. Born on December 29, 1973, in Barquisimeto, Venezuela, Perez began his professional career when he was signed by the Toronto Blue Jays as an amateur free agent in 1991. He made his MLB debut with the Blue Jays on May 3, 1995.

During his time with Toronto, Perez played primarily as a shortstop but also filled in at second and third base. His tenure with the Blue Jays lasted until 1998, after which he was claimed off waivers by the Philadelphia Phillies. It was with the Phillies that Perez spent the majority of his career, from 2000 to 2005, becoming a familiar face to the fans at Veterans Stadium and later Citizens Bank Park.

Perez was known for his defensive skills and versatility, often being used in a utility role. He played all infield positions and occasionally in the outfield, providing managers with flexibility in their lineups. While his batting average was modest, Perez was appreciated for his ability to come through in clutch situations and his light-hearted presence in the clubhouse.

In 2006, Perez signed with the Tampa Bay Devil Rays, where he continued to serve as a utility infielder. His stint with the Devil Rays was followed by a brief period with the Cleveland Indians in 2007. Perez's final MLB appearance came with the Houston Astros in 2008, marking the end of his major league playing days.

Throughout his career, Perez was valued for his adaptability on the field and his positive influence in the dugout.
