Pittsburgh Pirates

Lore & Background

The roots of this rivalry stretch back to the formative years of professional baseball. While the Cubs (then known as the White Stockings) were charter members of the National League in 1876, the Pirates (often called the Alleghenys or Bucs) joined the league a decade later in 1887. Despite this difference in founding status, both teams quickly became frequent contenders for the National League title throughout the late 1800s and early 1900s, setting a precedent for high-stakes competition that defined their relationship for generations.

The dynamic shifted dramatically during the mid-20th century. The Pirates, led by Roberto Clemente and Bill Mazeroski, captured the World Series in 1960 and again in 1971, while the Cubs endured their own long droughts. This era cemented a narrative of contrasting fortunes: Pittsburgh often serving as the team that broke through while Chicago watched from the outside looking in. The rivalry was further intensified by the fact that both teams frequently occupied similar standings, making every head-to-head series a critical battle for playoff positioning.

Over the decades, the mutual respect between the fanbases grew alongside the competitive tension. While not as geographically close as the Cubs' rivalry with the Cardinals or the White Sox, the historical weight of their matchups carries significant lore. The exchange of players and managers over the years has added layers of complexity, with figures who once wore a Cub uniform often finding themselves leading the Pirates in crucial moments, blurring the lines between friend and foe.

In Their Own Story

The wind whipped off Lake Michigan, cutting through the ivy-choked brick of Wrigley Field with a chill that had nothing to do with October. In the stands, the air hung heavy with roasted peanuts and a specific, gnawing anxiety unique to Cubs fans. On the mound stood a Pirate pitcher, his yellow-and-black uniform a stark contrast against the green wall behind home plate. He wasn't just facing a batter; he was stepping onto a stage where every pitch echoed a century of parallel struggles. As the crowd roared, the sound seemed to bridge the gap between 1903 and today, reminding everyone in the bleachers that while eras changed from dead-ball sluggers to modern power hitters, the dance remained the same: two cities, one league, and an endless fight for a piece of glory that always felt just out of reach.

Reader's Guide

The origin of this rivalry lies in their shared status as charter members of the National League. The Cubs (originally the White Stockings) and the Pirates (then the Alleghenys) have been locked in a battle for dominance since the league's infancy, long before modern divisional lines were drawn. Their histories are mirror images: periods of simultaneous contention in the late 19th century, followed by decades where one team soared to World Series glory while the other languished in the shadows.

Pirates Tenure and Breakout Performance

Williams arrived in Pittsburgh via a unique trade mechanism involving coaching staff exchanges, moving from the Miami Marlins to the Pirates in October 2015. After a brief but effective stint with the Indianapolis Indians in early 2016, he made his Major League debut that September, though his initial appearance was statistically rough. His true impact began in 2017 when he transitioned from the bullpen into the starting rotation, posting solid numbers. However, it was the 2018 campaign where Williams truly defined his value to the franchise. He delivered a career-best season, finishing with a 14-10 record and a 3.11 ERA across 31 starts. This performance placed him among the National League's elite in wins and ERA rankings while securing the second-highest WAR among Pirates pitchers that year. Despite subsequent struggles in 2019 and 2020, including leading the league in home runs allowed, his 2018 dominance remains a high point of his tenure with Pittsburgh before he was designated for assignment.
