Tom Grieve's journey in professional baseball began when he was selected by the Washington Senators as the sixth overall pick in the 1966 Major League Baseball draft. Born on March 4, 1948, in Pittsfield, Massachusetts, Grieve quickly rose through the ranks of the Senators' minor league system, making his major league debut on July 5, 1970. As an outfielder, Grieve showcased his skills with the Senators, who would soon relocate and become the Texas Rangers in 1972.

Grieve's tenure with the Rangers spanned several seasons, during which he became a familiar face in the team's lineup. Known for his right-handed batting and throwing, he played primarily as an outfielder but also saw time as a designated hitter. His best season came in 1976 when he hit 20 home runs and drove in 81 runs, both career highs. That year, Grieve also achieved a batting average of .255, demonstrating his ability to contribute offensively to the team.

In 1977, Grieve was traded to the New York Mets as part of a four-team trade that included several players. His time with the Mets was short-lived, as he was traded again in 1978 to the St. Louis Cardinals. Grieve's major league playing career concluded with the Cardinals in 1979, marking the end of a decade-long presence in the big leagues.

Following his retirement as a player, Grieve transitioned into a front-office role with the Texas Rangers. In 1984, he was appointed as the team's general manager, a position he held until 1994. During his tenure as GM, Grieve was responsible for several key trades and acquisitions that shaped the Rangers' roster. His leadership in the front office was instrumental in laying the groundwork for the team's future successes.

After stepping down as general manager, Grieve continued his association with the Rangers as a broadcaster. His voice became synonymous with Rangers baseball, providing color commentary and insights for the team's television broadcasts. Grieve's deep knowledge of the game and his connection to the Rangers' history made him a respected figure in the broadcasting booth.

Throughout his career, both on and off the field, Tom Grieve remained a dedicated figure in the world of baseball.
