Altoona Curve
Nestled in the Allegheny Mountains, the Altoona Curve have served as the Pittsburgh Pirates' Double-A affiliate since their very first pitch in 1999—the longest uninterrupted affiliation in the Pirates' minor league system and a proving ground for stars from Andrew McCutchen to Gerrit Cole.
1999–2009
Building a Franchise
From expansion team to Eastern League contender
The Altoona Curve were born from the determination of local businessman Bob Lozinak and a coalition of Pennsylvania legislators who refused to let their city miss out on professional baseball. When the Eastern League announced plans to expand in the late 1990s, Lozinak put together a stadium financing package and site plan that won unanimous approval at the league's October 1997 expansion meeting in Las Vegas.
Blair County Ballpark (now Peoples Natural Gas Field) opened on April 15, 1999, when the Curve defeated the Bowie Baysox in front of an enthusiastic crowd. The 7,210-seat stadium, set against the scenic Allegheny Mountains, quickly became one of the most beloved venues in the Eastern League. The Curve drew strong crowds from the start, tapping into a baseball-hungry region that had been underserved by professional sports.
On the field, the early Curve teams served as an important development stop for a rebuilding Pirates organization. Future major leaguers including Jack Wilson, Craig Wilson, and Bronson Arroyo passed through Altoona in the early years. By the mid-2000s, the pipeline was producing elite talent—Andrew McCutchen played for the Curve in 2006 and 2007, showcasing the five-tool ability that would make him the 2013 NL MVP. Neil Walker, Jose Tabata, and other key Pirates contributors also developed in Altoona during this period.

2010–2019
Championship Years
Titles, top prospects, and sustained success
The 2010s were the most successful decade in Curve history. The team won its first Eastern League championship in 2010, establishing Altoona as not just a development stop but a winning franchise. The championship culture attracted attention from both fans and the Pirates organization, which continued to route its best prospects through the Allegheny Mountain city.
The talent that passed through Altoona during this era reads like a Pirates All-Star roster. Gerrit Cole, the No. 1 overall pick in the 2011 draft, made his Double-A debut with the Curve. Starling Marte was named the Eastern League's Rookie of the Year in 2011 after hitting .332 in 129 games. Jameson Taillon, Gregory Polanco, Josh Bell, and Bryan Reynolds all developed their games at Peoples Natural Gas Field before becoming contributors in Pittsburgh.
The pinnacle came in 2017, when manager Michael Ryan led the Curve to their second Eastern League championship. That season's roster featured several future major leaguers and showcased the depth of the Pirates' farm system. The 2018 team went 78-60 under Ryan and made the playoffs again, marking a sustained period of excellence. Even as the Pirates' major league roster struggled, the Curve remained one of the Eastern League's most competitive franchises.

2021–Present
New Ownership Era
Diamond Baseball Holdings and a fresh start
After the 2020 season was canceled due to the COVID-19 pandemic and minor league baseball underwent a major reorganization, the Curve returned in 2021 as part of the restructured Double-A Northeast (later reverting to the Eastern League name). The transition brought changes both on and off the field. The team cycled through several managers—Miguel Perez in 2021, Kieran Mattison in 2022, Callix Crabbe in 2023, and Robby Hammock in 2024—as the Pirates organization sought the right leadership for their Double-A affiliate.
The biggest change came off the field in 2023 when the Lozinak family sold the franchise to Diamond Baseball Holdings, a conglomerate that owns and operates more than 20 minor league teams. The sale ended a quarter-century of local ownership but brought institutional resources and operational expertise to the franchise. DBH has invested in modernizing the fan experience while maintaining the Curve's community identity.
The 2025 season marked a turning point when Andy Fox was named manager, bringing stability and experience from his time as a coach with the Boston Red Sox organization. Fox led the Curve to a 69-68 record and their first playoff appearance since 2018, energizing the fanbase and earning a return engagement for 2026. The Curve continue to serve as the critical Double-A step in the Pirates' development pipeline, sending players like Nick Gonzales and Henry Davis toward Pittsburgh.
