William Culp Krueger (born April 24, 1958) is a former Major League Baseball pitcher, who played from 1983 to 1995 for eight teams.

He pitched for the Oakland A's, Los Angeles Dodgers, Milwaukee Brewers, Seattle Mariners (twice), Minnesota Twins, Montreal Expos, Detroit Tigers, and San Diego Padres.

Dayley had a successful big league career and was a key bullpen member of the St. Louis Cardinals World Series Championship team in 1985.

In 1980, Krueger was signed by the Oakland Athletics on July 12 as an undrafted amateur free agent and assigned to the Medford A's of the short-season single-A Northwest League despite only pitching 4 innings in college.

The West Haven club won the Eastern League Championship and Krueger made the AA All-Star Team.

Although Angels Brian Downing singled against him to lead off the game, Krueger got veteran right fielder Juan Beníquez to hit into a 4–6–3 double play.

In 1988, he had his best season as a pro, going 15–5 and leading the Pacific Coast League in wins, earned run average, and shutouts.

Krueger was traded to Montreal, where he spent 60 days before free agency whisked him to Detroit to play for the Tigers.

After being released from the Tigers mid-season in 1994, Krueger tried to revive his career in San Diego, where he pitched for the Padres until the strike in 1994.

Bill Krueger won his last game as a major leaguer on August 6 in the same place he started his career; the Oakland Coliseum.

In 2012 at age 54, he experienced sudden cardiac arrest on August 10 at the Redmond Pro Sports Club, where four employees worked together to assist in saving his life.
