Matt Sinatro's journey through Major League Baseball is a tale of perseverance and adaptability. Born on March 22, 1960, in Hartford, Connecticut, Sinatro's path to the big leagues began when he was drafted by the Atlanta Braves in the second round of the 1978 MLB Draft. As a catcher, he was known for his defensive skills and ability to work with pitchers, traits that would define his career in the majors.

Sinatro made his MLB debut with the Braves on September 14, 1981. His time with Atlanta was marked by limited playing opportunities, as he served primarily as a backup catcher. Despite the challenges of limited playing time, Sinatro's defensive prowess and understanding of the game allowed him to maintain a presence in the league.

In 1984, Sinatro was traded to the Oakland Athletics, where he continued to play a supporting role. His tenure with the Athletics was brief, and he found himself moving to the Detroit Tigers in 1986. With the Tigers, Sinatro again faced the challenge of limited playing time, but he remained a reliable option behind the plate when called upon.

The Seattle Mariners became Sinatro's next destination in 1987. It was with the Mariners that he spent the majority of his MLB career. Over several seasons, he provided depth to the Mariners' catching corps, offering guidance to younger pitchers and contributing to the team's defensive efforts. His role as a backup catcher often meant he was not in the spotlight, but his teammates and coaches valued his experience and steady presence.

Sinatro's final stop in the majors came with the California Angels in 1992. Although his playing time was sparse, he continued to demonstrate the qualities that had kept him in the league for over a decade. His career in the majors concluded after the 1992 season, marking the end of a journey characterized by adaptability and a deep understanding of the game.

Following his playing career, Sinatro transitioned into coaching, where he applied his extensive knowledge of baseball. He served as a coach for several MLB teams, including the Seattle Mariners and the Chicago Cubs, working alongside managers like Lou Piniella. His experience as a player, particularly his ability to handle pitchers and manage games from behind the plate, translated well into his coaching roles.
