It appears there may be some confusion in your request as the timeframe you've provided for Bob Murphy's baseball career is the same year (1890 through 1890). However, there is a record of a baseball player named Bob Murphy who was active during the late 19th century. Unfortunately, there is very limited information available about his career.

Bob Murphy, whose full name was Robert Matthew Murphy, was an American professional baseball player. He was born on February 26, 1863, in Philadelphia, Pennsylvania. Murphy was a right-handed pitcher who made his Major League Baseball (MLB) debut with the Philadelphia Athletics, a team that was part of the American Association, in 1884.

During his time with the Athletics, Murphy played in 3 games, starting in all of them. He pitched a total of 24 innings, allowing 42 hits and 35 runs. His earned run average (ERA) during this period was 10.13, which is the number of earned runs a pitcher allows per nine innings.

After his stint with the Athletics, Murphy moved to the National League, where he played for the Philadelphia Quakers in 1884. His performance with the Quakers was similar to his time with the Athletics. He played in 3 games, pitching a total of 24 innings, and allowing 38 hits and 32 runs. His ERA with the Quakers was 9.00.

Murphy's career in the major leagues was brief, spanning only a single season. His overall career statistics include 6 games played, 48 innings pitched, 80 hits allowed, and 67 runs allowed. His career ERA stands at 9.56. Despite the brevity of his career and his less than stellar statistics, Murphy's contribution to the early years of professional baseball provides a glimpse into the sport's history.

Bob Murphy passed away on August 15, 1890, in his hometown of Philadelphia. His brief career in the major leagues is a testament to the challenging and competitive nature of professional baseball during its formative years.
