Lehigh Valley IronPigs

Allentown, Pennsylvania, in the Lehigh Valley region of eastern Pennsylvania, has a professional baseball history dating back to 1884 with the Allentown Dukes of the original Eastern League. Though the city went through several stretches without a team, various other Minor League Baseball teams hailed from Allentown through 1960. The last of these were the Allentown Cardinals (1944–1956) and Allentown Red Sox (1958–1960). The Red Sox played at Breadon Field (later called Max Hess Stadium) at the site where the Lehigh Valley Mall was later built.

These affiliated clubs were followed by two independent baseball teams: the Allentown Ambassadors of the Northeast League and the Lehigh Valley Black Diamonds of the Atlantic League of Professional Baseball. The Ambassadors played at Bicentennial Park in Allentown until the team was disbanded after the 2003 season. The Black Diamonds moved from Newburgh, New York, in 1999 and were expected to move into a new ballpark near Easton called the Lehigh Valley Multi-Purpose Sport Complex, but the project never came to completion and ultimately was terminated. While the Black Diamonds waited for their new stadium, they played as a traveling team from 1999 to 2001.

In 2003, Joseph Finley and Craig Stein began actively pursuing their interest in bringing affiliated baseball back to Allentown. Initially, the duo pursued a Class A franchise when the Ottawa Lynx, the Triple-A affiliate of the Baltimore Orioles at the time, were rumored to be moving to Harrisburg. When the city of Harrisburg was unwilling to upgrade Commerce Bank Park to Triple-A standards, the Orioles shifted their interest to Allentown because of its proximity to the Mid-Atlantic. The Philadelphia Phillies also looked into moving their Triple-A operations to Allentown from the Scranton/Wilkes-Barre region. For the 2007 season, the Phillies shifted their Triple-A affiliate to Ottawa, leaving the Scranton/Wilkes-Barre Red Barons after 18 seasons, while the Orioles affiliated with the Norfolk Tides. The Phillies signed a one-year Player Development Contract with the Lynx while the US$50.25-million Coca-Cola Park capable of seating up to 8,100 people with a total capacity of 10,000, was being constructed in Allentown.

The Ottawa Lynx were relocated to Allentown in 2008 and continued as the Triple-A affiliate of the Philadelphia Phillies in the International League (IL). Known as the Lehigh Valley IronPigs, their moniker, selected in a name-the-team contest, refers to the region's steelmaking history, in particular the refining of pig iron into steel. The other finalists were "Gobblers", "Crushers", "Phillies", "Phantastics", "Vulcans", "Keystones", and "Woodchucks".

The IronPigs played their first Opening Day game on the road, losing to the Scranton/Wilkes-Barre Yankees, 4–0, on April 3, 2008. The team went on to lose their next 10 games. On April 14, Lehigh Valley broke the 11-game losing streak, defeating the Richmond Braves, 3–1, at their new home stadium, Coca-Cola Park. They ended their inaugural season last of 14 teams in the IL at 55–89. The next season, Justin Lehr became the first member of the team to win a league year-end award when he was selected as the International League's 2009 Most Valuable Pitcher. On July 14, 2010, Coca-Cola Park hosted the Triple-A All-Star Game. In the event, which was broadcast nationally on MLB Network, a team of the IL's All-Stars defeated a team of the Pacific Coast League's All-Stars, 3–1.

Baseball Hall of Fame inductee Ryne Sandberg became manager of the IronPigs in 2011. On April 7, they won their season opener against the Scranton/Wilkes-Barre Yankees at Coca-Cola Park, registering the first win–loss percentage above .500 in the team's history. Sandberg led the club to an 80–64 record which, though not good enough to win the Northern Division title, gave them a wild card berth into the Governors' Cup playoffs for the International League championship. They won the semifinals over the Pawtucket Red Sox, 3–0, but lost the championship finals to the Columbus Clippers, 3–1. Tyler Cloyd was selected as the Most Valuable Pitcher in 2012.

From 2016 to 2018, Lehigh Valley made three consecutive appearances in the Governors' Cup playoffs. The 2016 wild-card winners set a season record for wins, with 85 against 58 losses, but were swept in three games by the Scranton/Wilkes-Barre RailRiders. Jake Thompson was the circuit's Most Valuable Pitcher. The 2017 team won another wild card berth but was eliminated again by Scranton/Wilkes-Barre, 3–1. Phillies prospect Rhys Hoskins was selected as the IL's 2017 Most Valuable Player (MVP) and Rookie of the Year.

In 2018, the IronPigs won their first Northern Division title with an 84–56 record, the highest winning percentage (.600) in franchise history, but were knocked out of the semifinals for the third year in a row by the RailRiders, 3–1. Nevertheless, the IronPigs swept the International League awards with Joey Meneses as MVP and Rookie of the Year, Cole Irvin as the top pitcher, and Gary Jones as the Manager of the Year winner.

The start of the 2020 season was postponed due to the COVID-19 pandemic before being cancelled on June 30. Through 13 seasons in the International League, the IronPigs had a 855–861 record. They experienced more success at the turnstiles as their season attendance topped 500,000 people each season. From 2008 to 2016, the team led Minor League Baseball with a per-game average attendance of 8,978. In 2019, franchise was recognized with the Larry MacPhail Award for outstanding minor league promotions.

Following the 2020 season, Major League Baseball assumed control of Minor League Baseball in a move to increase player salaries, modernize facility standards, and reduce travel. The Philadelphia Phillies retained Lehigh Valley as their Triple-A affiliate, but the International League disbanded, and the IronPigs followed the other IL teams into the Triple-A East. Lehigh Valley ended the season in fourth place in the Northeastern Division with a 52–66 record. No playoffs were held to determine a league champion; instead, the team with the best regular-season record was declared the winner. However, 10 games that had been postponed from the start of the season were reinserted into the schedule as a postseason tournament called the Triple-A Final Stretch in which all 30 Triple-A clubs competed for the highest winning percentage. The IronPigs finished the tournament in 30th place with a 1–9 record. In 2022, the Triple-A East became known as the International League, the name historically used by the regional circuit prior to the 2021 reorganization.

In August 2022, as Phillies' star right fielder Bryce Harper was designated to the IronPigs in a final step in his rehabilitation stint as part of his comeback from a fractured thumb, the IronPigs' games against the Gwinnett Stripers at Coca-Cola Park quickly sold out to the stadium's 10,100 capacity. In his August 23 appearance with the IronPigs, Harper homered twice against the Stripers.
