Dave Leiper, a left-handed relief pitcher, spent parts of nine seasons in Major League Baseball (MLB) with several teams. Born on June 18, 1962, in Whittier, California, Leiper attended the University of California, Berkeley, where he honed his skills on the mound before being drafted by the Oakland Athletics in the second round of the 1982 MLB Draft.

Leiper made his MLB debut with the Oakland Athletics on May 31, 1984. During his initial stint with the Athletics, he was primarily used as a relief pitcher, a role he would continue throughout his career. His time with Oakland was marked by his ability to handle left-handed hitters effectively, a valuable asset for any bullpen.

In 1986, Leiper was traded to the San Diego Padres, where he continued to serve as a reliable option out of the bullpen. His tenure with the Padres saw him develop further as a pitcher, gaining more experience and refining his pitching techniques. Leiper's ability to maintain composure in high-pressure situations made him a dependable choice for managers looking to secure late-inning leads.

After a brief return to the Athletics in 1989, Leiper found himself on the move again, this time to the Montreal Expos in 1990. His time with the Expos was marked by consistent performances, and he became a familiar face in their bullpen rotation. Leiper's role often involved facing tough left-handed batters, and he was known for his strategic approach to pitching, utilizing his fastball and slider to keep hitters off balance.

Leiper's career also included stints with the Philadelphia Phillies and the Minnesota Twins. Each team benefited from his experience and ability to adapt to different game situations. Despite not being a headline-grabbing player, Leiper's steady presence in the bullpen provided much-needed depth to the teams he played for.

Throughout his career, Leiper's statistics reflected his role as a situational pitcher. He appeared in 321 games, all but one as a reliever, and posted a career earned run average (ERA) of 3.98. His ability to limit damage and maintain control on the mound was evident in his career strikeout-to-walk ratio, which highlighted his precision and understanding of the game.

Leiper's final MLB appearance came in 1996 with the Philadelphia Phillies.
