Scott Garrelts, a right-handed pitcher, spent his entire Major League Baseball career with the San Francisco Giants. Born on October 30, 1961, in Urbana, Illinois, Garrelts was drafted by the Giants in the first round of the 1979 MLB Draft. He made his major league debut on October 2, 1982, and quickly became a reliable presence on the mound.

Garrelts initially served as a relief pitcher for the Giants. In the early years of his career, he demonstrated his ability to handle high-pressure situations, often being called upon to close games. His performance in the bullpen was marked by a strong fastball and effective breaking pitches, which helped him secure a role as one of the team's primary relievers.

The 1985 season was a turning point for Garrelts, as he transitioned from the bullpen to the starting rotation. This move allowed him to showcase his skills over longer outings, and he adapted well to the change. In 1989, Garrelts had one of his best seasons, posting a 14-5 record with a 2.28 ERA, which was the lowest in the National League that year. His performance earned him a spot on the National League All-Star team, highlighting his status as one of the league's top pitchers.

Garrelts played a crucial role in the Giants' success during the 1989 season, helping the team reach the World Series. Although the Giants ultimately fell to the Oakland Athletics in the series, Garrelts' contributions throughout the season were instrumental in their journey to the championship.

Injuries began to take a toll on Garrelts in the early 1990s, limiting his effectiveness and availability. Despite these challenges, he continued to pitch for the Giants until the end of his career in 1991. Over his ten-year career, Garrelts compiled a 69-53 win-loss record, with a 3.29 ERA and 703 strikeouts.
