PITTSBURGH (AP) — Clint Hurdle's booming voice and unrelenting optimism helped shake the Pittsburgh Pirates out of two decades of misery. His charisma gave the moribund franchise an identity, one that reconnected the franchise with a fan base worn down by years of losing.Yet over the years, as the core that led the team to three straight playoff berths from 2013-15 vanished with trades, retirement and the pursuit of financial riches elsewhere, that optimism started to fly in the face of reality. Pittsburgh fell off the pace after winning 98 games in 2015, and as players shuffled in and out, the giddiness of those three intoxicating years of contention faded.When Hurdle arrived for work on Sunday for Pittsburgh's regular season finale against Cincinnati, the Pirates were assured of their worst record since 2011, his first season on the job. By the time Trevor Williams threw the first pitch to José Peraza, Hurdle already was headed home, his nine seasons in Pittsburgh over following a stunning second-half collapse marred by embarrassing off-the-field issues that indicated a clubhouse in disarray.Calling it "an extremely difficult decision," Pirates general manager Neal Huntington fired Hurdle in the final hours of a disappointing year, putting an abrupt end to a partnership that guided Pittsburgh back to relevance. Huntington stressed the club wasn't making Hurdle a scapegoat for failings that stretched far beyond the manager's reach. The Priates entered Sunday 69-92, including 25-47 since the All-Star break."There is no one thing that led us to this decision," Huntington said. "It's easily summed in new voice, new leadership, new direction in the clubhouse but I'm not saying it's his fault. I'm sitting here wearing it. We are wearing it as an organization, and we're going to work our tails off to never be in this spot again."Hurdle went 735-720 in Pittsburgh, the fourth-winningest manager in the franchise's 132-year history in the National League. He took over a team coming off a 105-loss season the year before his arrival and with the help of a group that included star centerfielder Andrew McCutchen, orchestrated a revival that saw Pittsburgh become contenders in the NL Central.Yet the Pirates never made it past the Division Series over the course of three consecutive playoff appearances, The team slid back to mediocrity as A.J. Burnett retired in 2015, McCutchen and pitcher Gerrit Cole were traded in January 2018, and catcher Russell Martin and pitcher J.A. Happ both landed lucrative deals as free agents.Pittsburgh averaged just 76 victories over Hurdle's final four seasons. He leaves with two years remaining on a contract extension he signed in 2017.Bench coach Tom Prince filled in for Hurdle as manager after Hurdle declined the option of working one last day. Huntington said he will explore both internal and external options. Prince and special assistant Jeff Banister — who took the Texas Rangers to the playoffs in 2013-14 before returning to Pittsburgh — both have deep ties to the team.Pirates chairman Bob Nutting said in a statement that he had "a great deal of appreciation" for Hurdle's contributions to the organization. Nutting called 2019 "easily the most difficult season" of a tenure that dates to 2007. While Hurdle is moving on, Huntington, whose contract runs through 2021, is not."I strongly believe that Neal Huntington and the leadership team that he has assembled are the right people to continue to lead our baseball operations department," Nutting said.Hurdle is the fifth departing major league manager. San Francisco's Bruce Bochy and Kansas City's Ned Yost announced their retirements, San Diego's Andy Green was fired on Sept. 21, and the Cubs' Joe Maddon and Chicago announced Sunday he will not return.Oakland's Bob Melvin, hired in June 2011, became the longest-tenured manager in the major leagues.Hours before his departure, Hurdle said he had guarded optimism about the direction of the team despite its post All-Star break funk. Pittsburgh entered the break at 44-45 but promptly lost 24 of its next 28 games. He told The Athletic last week he had received assurances he would return in 2020.On Sunday morning he allowed that it's a manager's job to sell tickets. Attendance at PNC Park has dropped in lock step with Pittsburgh receding from contention in recent years. Pittsburgh entered Sunday averaging just 18,348 fans, down from 30,847 when the club won 98 games in 2015."When you don't play well, the responsibility falls upon the manager of the team," Hurdle said. "Then the people that make those decisions on whether the manager stays or the manager goes, coaching staff goes, coaching staff stays, players go, players stay, that's what front office does. . I've always felt I have a really good grasp on what my accountability and responsibility is. I've never shirked away from it or never not owned up to it. So, absolutely not winning enough games falls right here."Off the field, pitcher Felipe Vázquez was charged with statutory sexual assault, unlawful contact with a minor and corruption of minors, all felonies, and a misdemeanor count of indecent assault of a person under 16 years old. Reliever Keone Kela was suspended for an argument with a team official, and Vazquez and reliever Kyle Crick got into a fight that resulted in Crick needing season-ending surgery on his right index finger."(There are) players that have come through our system that talked about, 'This is not what the Pirates do. This is not who we are,'" Huntington said. "I'm not going to sit here and say that it's Clint Hurdle's fault. It's all of us. It's all of us in this."___More AP MLB: https://apnews.com/MLB and https://twitter.com/AP_Sports
