Arizona Diamondbacks (2001–2004) The firing of Diamondbacks manager
Buck Showalter a day after the 2000 season lent an opportunity for Brenly, who was one of the seven candidates interviewed by Arizona alongside
Chris Chambliss,
Carlos Tosca,
Clint Hurdle,
Tom Spencer,
Ron Hassey, and
Terry Francona; Brenly and Francona were the final two considered. On October 30, he was signed to a three-year, $2 million contract. He was cited by general manager
Joe Garagiola Jr and managing partner
Jerry Colangelo for his "baseball knowledge, work ethic and attitude", which contrasted with the "micromanaging" Showalter, who had won 250 of 486 games but had failed to reach past the
National League Division Series. With veteran stars such as
Luis Gonzalez,
Randy Johnson, and
Curt Schilling, expectations were good for the team to win when they still had a chance to do so. The Diamondbacks won 92 games in his rookie season, finishing two games ahead of the
San Francisco Giants, the defending NL West champion. In the
2001 National League Division Series, they played against the
St. Louis Cardinals. The two teams split the first four games before Arizona won on a walk-off by
Tony Womack for their first postseason series win. In the
2001 National League Championship Series against the
Atlanta Braves, they split the first two games against each other before they rolled the next three games over Atlanta (with Schilling and Johnson winning two of the three games) to clinch the National League pennant. In the
2001 World Series, they were matched against the
New York Yankees, who had won the last three World Series matchups and were looking for a four-peat with heavy odds in their favor. As per the tradition of the time for home-field advantage in the World Series having the National League host in odd-number years, Arizona hosted the first two games. They outscored the Yankees 13-1 in those games with Johnson and Schilling coming through with decisive victories. When the Series shifted to New York, Brenly's team dealt with adversity. Game 3 saw them held to three hits and one run while New York narrowly won. Schilling was sent out for Game 4, but it was the bullpen that proved noteworthy. With a two-run lead in the eighth inning, closer
Byung-hyun Kim was sent out by Brenly to pitch not only the 8th but also the 9th inning. He had a clean 8th, but the lineup in the 9th proved his undoing.
Paul O'Neill got on base with one out before
Tino Martinez lined a home run to tie the game and send it to extras. Kim was sent out for another inning to try and preserve the tie, but
Derek Jeter hit a two-out walk-off home run to tie the series. For Game 5, Brenly went to
Miguel Batista, who hadn't pitched in twelve days, to the mound. He had a scoreless 7.2 inning performance, and the Diamondbacks lead 2-0 into the 9th inning. Brenly sent out Byung-hyun Kim to try and save the game despite what happened the previous night. With two outs and a runner on,
Scott Brosius hit a home run to tie the game and send it to extras. In the 12th, the Yankees walked the game off on a RBI single to send the Yankees one victory away from a title going into Arizona. In Game 6, the Diamondbacks rode Johnson to a dominant victory 15-2 before Schilling was sent out to try and win the Series in the 7th game, once again pitching on three days rest. When Schilling was taken out after trailing 2-1 in the 7th, Brenly put in Batista to get a crucial out before putting in Johnson (104 pitches the night before) to get outs in the 8th and 9th inning. A 9th inning rally would end with Gonzalez lining a soft shot into the outfield to deliver a championship for Arizona. Although the team repeated as
Western Division champions in 2002, they lost in the Division Series. The 2003 team had exactly two winning months (June and September) and went 84-78 for a 3rd place finish in the West. The 2003 offseason saw them trade away Schilling. The team had a terrible start to the 2004 season and never recovered, winning just nine games each in the first two months of the year while dealing with injuries. When they were 29-50, Brenly was fired, with Colangelo stating it was not a "change of reflection" on him. ==Personal life==
