A century's passage can easily erase the legacy of a frontline ace, leaving their greatest accomplishments forgotten in early baseball history. Wilbur Cooper exemplifies this neglect within Pirates history. A skilled, left-handed pitcher who used a sharp changeup and sinking fastball, Cooper spent over ten years dismantling National League lineups with calm precision. However, because his prime coincided with a rare, transitional period between the franchise's early wins, his name is seldom spoken with the same admiration as his peers.

His arrival in Pittsburgh midway through the 1912 season immediately revealed him as a dependable workhorse. Cooper made consistent durability a core part of his routine, expertly managing the tough transitions of the Deadball Era to secure his spot in the starting rotation.

His authentic ascent to elite status took place over an impressive eight-year peak from 1917 to 1924, during which he established himself as one of the most formidable and effective southpaws in Major League Baseball. Throughout this dominant period, Cooper consistently ranked in the top ten of the National League across nearly all key pitching categories, regularly surpassing 200 strikeouts and 300 innings, all while making run prevention appear effortless.

He surpassed the prestigious 20-win threshold four times while playing for Pittsburgh, highlighted by an outstanding 1922 season with a career-best 23 wins, 28 complete games, and a solid 3.18 ERA.

Through his remarkable longevity, Cooper etched his name into the major league record books as the first left-handed pitcher in the National League to reach 200 career wins. Although he didn't extend his total much beyond that, ending his career with 216 wins, his impact remains unparalleled. He is still the winningest pitcher in Pittsburgh Pirates history, with an impressive 202 victories that remain unmatched.

The tragic aspect of Cooper's legacy lies in unfortunate historical timing. After dedicating 13 seasons to the organization, he was traded to the Chicago Cubs before the 1925 season. That autumn, the Pirates secured an exciting World Series victory without him. If Cooper had been part of that championship team, his name might have been honored with a retired number and physical memorials, solidifying his place in history.

Modern advanced metrics and analytical filters have thankfully begun to rescue his profile, highlighting his immense 48.2 career bWAR anchor as a Pirate.

The history of major league baseball features many legendary sluggers with impressive career statistics, but Ralph Kiner stood out in the post-war era for his extraordinary power. For seven summers after World War II, this handsome, broad-shouldered left fielder transformed Forbes Field's left-field seats into his personal zone of dominance. During a difficult period for the franchise, Kiner alone kept attendance high by setting a record for home run frequency that remains unmatched.

His debut in the major leagues during the 1946 season provided little hint of the monumental impact that would come later. Although Kiner secured the National League home run title as a rookie, his stats were somewhat misleading: he ended with only 23 home runs, led the league with 109 strikeouts, and had a rather modest .430 slugging percentage.

Instead of allowing rookie struggles to shape him, Kiner undertook a remarkable journey of self-improvement, guided by his new teammate Hank Greenberg. He methodically adjusted his batting style, reducing his swing size and significantly increasing his plate discipline, turning his extra-base power into a consistent part of his daily game.

What followed was a stunning, high-output assault on the record books. Kiner achieved an incredible streak of seven straight home run titles from 1946 to 1952, a feat that still stands unmatched in baseball history.

Over the next five summers, he consistently surpassed 40 home runs, with two seasons exceeding 50. His best season was in 1949, when he hit a career-high 54 home runs, drove in 127 RBIs, and achieved an impressive .658 slugging percentage.

Kiner was far from a simple, all-or-nothing free swinger. He developed an exceptionally keen eye at the plate, leading the Senior Circuit in walks three times and surpassing a .400 on-base percentage three times, notably hitting a league-high .452 OBP in 1951. He won three slugging titles, three OPS titles, and finished in the top ten in National League MVP voting for five consecutive years from 1947 to 1951.

Sadly, Kiner’s remarkable individual achievements took place on Pittsburgh teams that were mostly poor, finishing with only one winning record during his time. This clear contrast between his superstar performance and the team's struggles led to a well-known financial dispute with GM Branch Rickey. After Kiner refused a salary cut after hitting 37 home runs, Rickey famously declared: "We finished last with you; we can finish last without you."

True to his promise, Rickey traded the franchise icon to the Chicago Cubs in mid-1953 in a large ten-player deal. Kiner's peak performance, characterized by high velocity, soon declined; persistent back degeneration severely limited his power, ultimately ending his career by the end of the 1955 season at only 32 years old.

He left the Steel City having accumulated an exceptional localized baseline of 301 home runs, 801 RBIs, and a spectacular .280/.405/.567 slash line across 1,095 games.

Kiner famously began a second, highly successful career as a beloved broadcaster for the New York Mets, keeping his voice a part of the sport for generations. The peak of his greatness was confirmed in 1975 when baseball writers inductively voted him into the Baseball Hall of Fame in his last eligible year.

To permanently mark his monumental impact on the community, the organization, with deep reverence, moved to elevate his legacy to the rafters of Three Rivers Stadium, officially retiring his iconic number 4 jersey in 1987.

The history of pitching is full of fire-breathers who used raw speed to overpower batters, but Babe Adams took a different approach. Throughout his 19-year MLB career, mostly with the Pittsburgh Pirates, except for a brief relief stint with the St. Louis Cardinals in 1906, Adams made his mark with remarkable control. He turned the strike zone into his personal canvas of precision, effectively neutralizing the best hitters of the Deadball Era by avoiding unnecessary walks.

His official debut as a key player coincided with the historic 1909 pennant race, leading to one of the most memorable rookie performances ever seen on baseball's biggest stage. Facing Ty Cobb and the formidable Detroit Tigers in the Fall Classic, manager Fred Clarke gambled on his young right-hander. Adams responded with exceptional excellence, pitching and winning three games, including a complete-game shutout in the crucial Game 7. He dominated the American League champions over 27 intense innings, allowing only four runs, ending the series with a remarkable 1.33 ERA and a 0.889 WHIP, earning Pittsburgh its first world championship.

Far from being just a flash in October, Adams quickly proved himself as a top-tier pitcher. He showcased a remarkably smooth and effortless delivery paired with a potent curveball, achieving two outstanding 20-win seasons in 1911 and 1913. Consistently excelling in run prevention and baserunner suppression, he led the National League in WHIP in 1911 and 1914, and frequently topped the circuit in FIP. This highlights that his effectiveness was largely independent of his team's defensive support.

Yet, the immense physical toll of throwing over 300 innings a year finally caught up to him. A severe shoulder injury severely derailed his velocity, culminating in a dismal 1916 campaign that looked like a permanent career exit. Adams spent the bulk of the subsequent two summers buried in the minor leagues, a stretch that would have broken a lesser competitor.

His second act represents one of the greatest, unheralded comeback stories in baseball folklore. Returning to Forbes Field in 1919 with a completely rebuilt pitching repertoire, Adams embarked on a spectacular twilight peak that defied both Father Time and the explosive arrival of the live-ball era. From 1919 through 1921, he systematically paralyzed National League lineups to lead the league in WHIP for three consecutive summers. Even more staggering, across a four-year window from 1919 to 1922, his control reached an era-defining peak, leading all of baseball in fewest walks per nine innings and strikeout-to-walk ratio. Opposing hitters knew exactly where the pitch was going, but his pinpoint accuracy meant they still couldn't square it up.

By the time the mid-1920s rolled around, Adams had transitioned into a revered, 40-something elder statesman in the clubhouse. While his overall playing time was significantly reduced, he served as a highly functional veteran anchor on the historic 1925 championship roster. When the Pirates defeated Washington in a thrilling seven-game Fall Classic that October, Adams etched his name permanently into a unique corner of club lore, becoming the solitary player to bridge the generation gap as a member of both the 1909 and 1925 World Series title teams.

By 1924, his performance had declined, but he was in his 40s by then. In 1925, Adams participated in the World Series; although he had limited playing time, he helped the championship team. This made him the only player to win both Pittsburgh's 1909 and 1925 World Series titles. His final season was in 1926, and he retired with a record of 194-139 and a WHIP of 1.090.

When Willie Stargell debuted for the Pirates in late summer of 1962, he didn't immediately shift the National League's landscape, but the tall left-handed slugger from Oklahoma quickly became a towering presence. Initially playing left field, "Pops" spent the 1960s providing raw power alongside Roberto Clemente. He swung a heavy bat with a distinctive, sweeping motion that struck fear into pitchers, routinely hitting tape-measure home runs over Forbes Field's roofs.

By the 1970s, his influence soared to a historic, league-shaping peak. Stargell won two National League home run titles, hitting a career-best 48 in 1971 and 44 in 1973. In those standout seasons, he also led the league in slugging percentage and narrowly missed the MVP award. As the cleanup hitter for the "Lumber Company" lineup that won the 1971 World Series, his true masterpiece was reserved for the final years of his career.

By the late 1970s, Stargell had moved to first base and became the team's clear leader. Before the famous 1979 season, he changed the clubhouse atmosphere by adding embroidered "Stargell Stars" to the team's unique pillbox caps, giving them to players who performed well in key moments. With his guiding presence, the team embraced Sister Sledge’s song "We Are Family," turning their baseball squad into a symbol of unity and culture.

In the diamond spotlight, the 39-year-old veteran led the team to victory. He shared the 1979 National League MVP award with Keith Hernandez and delivered an impeccable postseason performance. Stargell expertly broke down opposing pitchers, earning both the NLCS and World Series MVP honors. He became the first player in major league history to win all three MVP titles in one season, highlighted by a crucial, go-ahead home run in Game 7 against Baltimore that clinched the world championship.

His physical baseline broke down rapidly under the weight of knee injuries following that magical autumn, limiting his playing time until his permanent retirement at the conclusion of the 1982 schedule. He walked away from the diamond as a lifelong, 21-year one-uniform icon, holding the definitive all-time franchise records with 475 home runs and 1,540 runs batted in.

The Pirates retired his No. 8, and in 1988, he was inducted into the Baseball Hall of Fame on his first ballot. The franchise also unveiled a bronze statue of Stargell outside PNC Park to honor his legacy.
