Bob Weiland, a left-handed pitcher, played in Major League Baseball during an era when the sport was evolving rapidly. Born on December 14, 1905, in Chicago, Illinois, Weiland began his professional career with the Chicago White Sox. His debut in the major leagues came on April 30, 1928, marking the start of a career that would span over a decade.

Weiland's early years with the White Sox were marked by a mix of challenges and learning experiences. As a pitcher, he was known for his ability to deliver a solid performance on the mound, although he often struggled with control issues. Despite these challenges, Weiland's perseverance and skill earned him a place in the starting rotation, where he continued to develop his craft.

In 1930, Weiland was traded to the Boston Red Sox, where he spent several seasons. His time with the Red Sox was characterized by steady improvement and increased responsibility. Weiland's pitching style, which relied heavily on a fastball and a curveball, allowed him to compete effectively against some of the best hitters of the time. However, his tenure with the Red Sox was not without its difficulties, as he continued to battle control problems that occasionally led to high walk rates.

The mid-1930s saw Weiland move to the Cleveland Indians, where he played for a brief period before being traded to the St. Louis Browns. His stint with the Browns was relatively short, but it provided him with an opportunity to refine his pitching technique and gain valuable experience in different playing environments.

In 1937, Weiland joined the St. Louis Cardinals, a team with which he would enjoy some of his most productive years. During his time with the Cardinals, Weiland became known for his ability to pitch effectively in high-pressure situations. His performance in the 1938 season was particularly noteworthy, as he achieved a career-best earned run average (ERA) of 3.24. This period marked a high point in Weiland's career, as he demonstrated his capability to contribute significantly to his team's success.

Weiland's career continued with the Cardinals until 1940, when he played his final major league game on September 23. Over the course of his career, Weiland compiled a win-loss record of 62-94, with an ERA of 4.24 and 514 strikeouts. While his record may not reflect dominance, it underscores the challenges and competitiveness of the era in which he played.

After retiring from professional baseball, Weiland's life away from the diamond remained relatively private.
