Scott Feldman, a right-handed pitcher, began his Major League Baseball career with the Texas Rangers. Drafted in the 30th round of the 2003 MLB Draft, Feldman worked his way through the minor leagues, making his MLB debut on August 31, 2005. Initially, he served as a relief pitcher, but his role evolved over time.

In 2008, Feldman transitioned to a starting pitcher, a move that proved beneficial for both him and the Rangers. The following year, 2009, marked a high point in his career with Texas. Feldman recorded a 17-8 win-loss record and a 4.08 ERA, leading the team in wins. His performance helped the Rangers secure a spot in the postseason, although they were ultimately eliminated in the American League Division Series.

Feldman's tenure with the Rangers continued until 2012, during which he experienced both successes and challenges. Injuries and fluctuations in performance led to a mix of starting and relief roles. In 2013, Feldman signed a one-year contract with the Chicago Cubs, where he started 15 games before being traded mid-season to the Baltimore Orioles. His time with the Orioles was brief, but he contributed to their push for a playoff berth.

The next chapter of Feldman's career began in 2014 when he signed a three-year contract with the Houston Astros. As a veteran presence on a young team, Feldman provided stability to the Astros' rotation. In his first season with Houston, he posted an 8-12 record with a 3.74 ERA over 29 starts. Injuries, however, limited his playing time in the subsequent seasons.

In 2016, Feldman was traded to the Toronto Blue Jays, where he served primarily as a reliever. The following year, he signed with the Cincinnati Reds, returning to a starting role. Feldman pitched for the Reds until a knee injury ended his season prematurely. This injury ultimately led to the conclusion of his professional playing career.

Throughout his time in MLB, Feldman was known for his sinkerball, which induced ground balls and helped him navigate through lineups.
