Claimed off waivers by the Milwaukee Brewers following the 2004 season, Turnbow worked with Brewers pitching coach Mike Maddux before the 2005 season to help control his fastball, which routinely clocked in at 97-98 mph. Turnbow became the Brewers' closer in April 2005 and finished the 2005 season with 39 saves, matching the team record set previously by Dan Kolb in 2004, and setting personal bests with a 1.74 ERA and 7-1 record in 67.1 innings pitched. Turnbow was rewarded with a three-year $6.5 million contract, which ran through 2008 and "bought out" his first two seasons of arbitration eligibility.

2006 season
Before the 2006 season, Turnbow signed a three-year contract extension worth a guaranteed $6.5 million.[4] In April 2006, Turnbow made major league history since saves became an official statistic in 1969 by earning a save in each of the first four games of the season.[5] In 2006, he was selected to his first All-Star team. Turnbow struggled with his command through the 2006 season, however, converting only 1 of 5 save opportunities and posting a 21.32 ERA in July 2006, and causing manager Ned Yost to remove Turnbow from the closer role in favor of Francisco Cordero.[6]
