In December 1964, Claude Osteen became a Los Angeles Dodger as the centerpiece of a seven-player trade that sent power-hitter Frank Howard to the Washington Senators. While the Dodgers were trading away a mountain of home runs, they were acquiring a "marathon man" of a southpaw who would spend the next decade defining durability in a rotation that already featured legends.

In his first season on the West Coast, Osteen reached a high point during the World Series against the Twins. When the Dodgers trailed 2-0, he started Game 3 with a five-hit shutout that shifted the series momentum. That summer, he commanded the strike zone, winning 15 games and achieving a career-high 162 strikeouts. Despite occasional hits allowed, he showed resilience, pitching at least 240 innings in nine of ten seasons with the team, becoming the staff's backbone.

During the late 1960s and early 1970s, Osteen enjoyed seven seasons with at least 15 wins for the Dodgers, reaching his peak in 1969 and 1972, with 20 wins in each year. He achieved a historic milestone by being named to three All-Star teams (1967, 1970, 1973), demonstrating that a control-oriented left-handed pitcher could still attain greatness in an era increasingly focused on velocity. His tenure was distinguished by his specialized ability to complete what he started, recording 118 complete games as a Dodger.

After the 1973 season closed, he was traded to the Houston Astros in an exchange that brought the Dodgers Jim Wynn.  With Los Angeles, Osteen compiled a 147-126 record, a 3.06 ERA, and 1,162 strikeouts.

Jimmy Sheckard played for Brooklyn on three different occasions; though this was in a tight vacuum, you could argue that his first MLB half was indeed with Brooklyn.

Following his ‘loan' to the Baltimore Orioles in 1899, where he led the league with 77 stolen bases, Sheckard returned to Brooklyn in 1900 and achieved the pinnacle of his individual performance in 1901. He authored a remarkable season, batting a career-high .354 and leading the National League in triples (19) and slugging percentage (.534). He demonstrated comprehensive mastery of the game that summer, recording 104 RBIs and 11 home runs, a statistical record that cemented his reputation as the most formidable hitter in a lineup that secured consecutive pennants for Brooklyn.

1903 would be an incredible campaign for Schekard. He enjoyed a campaign in which he led the league in both home runs (9) and stolen bases (67), a rare dual-honor summit reached by only a handful of players in history. While his offensive output sometimes dipped, like in the tough 1904 campaign, his defense was consistently top-notch. He was a mainstay in the outfield, setting a National League record with 14 double plays, showcasing a "cannon" arm that often ended rallies early.

Following a season at the bottom of the standings, the team traded the popular Sheckard to the Chicago Cubs for a four-player package including Jack McCarthy and Doc Casey. In Chicago, he reached new heights, winning two World Series titles and setting a season record with 147 walks, while his time in Brooklyn was also memorable. In Brooklyn, Sheckard had 966 hits, a .295 batting average, and 212 stolen bases.

Arriving in Brooklyn in 1892, William “Brickyard” Kennedy was a right-hander with a booming voice and a work ethic forged in the clay pits of his Ohio hometown. While he earned the nickname "Roaring Bill" for his vocal presence on the diamond, it was his off-season labor in a brickyard that gave him the moniker that would stick for over a century

Kennedy hit his peak early, with back-to-back 20-win seasons in 1893 and 1894. He demonstrated exceptional endurance, pitching a career-high 382.2 innings in 1893. Although his career 3.98 ERA in Brooklyn seems modest today, he reached a high value simply by staying on the mound. A key team presence, he remained competitive even in 1895 with a 19-12 record and a spikes to 5.05 ERA, showing teammates’ confidence in his ability to finish.

A key asset for the 1899 and 1900 Brooklyn Superbas, Kennedy helped them win consecutive National League pennants. He posted a 22-9 record with a 2.79 ERA in 1899, showing he still reached elite levels of efficiency. Beyond pitching, he was a skilled hitter, with 306 hits and a .256 average during his Brooklyn years, often contributing significantly during high-stakes battles of the 1890s.

After a decade of service and 177 wins, the organization concluded that his high-velocity years had ended and released Kennedy in 1901.  He compiled a 177-148 record, a 3.98 ERA, and 721 strikeouts for Brooklyn.

Bob Welch quickly became a well-known name in Southern California. Just a year after being the 20th overall pick in the 1977 draft from Eastern Michigan, the right-hander was pitching in the ninth inning of Game 2 of the 1978 World Series. In a pivotal moment early in his career, the 21-year-old rookie faced off against the legendary Reggie Jackson with two outs and the tying run on third. He ultimately struck out Jackson with a high fastball, sealing the win. This strikeout was more than just the end of a game; it marked the rise of a powerful pitcher who would be a key part of the Los Angeles rotation for the next decade.

While the 1978 highlight reel made him a star, Welch’s true strength was his ability to consistently dismantle National League lineups. By 1980, he received his first All-Star nomination, marking his emergence as a top-tier starter. As a key part of the 1981 staff that finally won the World Series, he provided stability amid the challenges of a split season. Welch demonstrated remarkable durability, achieving a four-year streak starting in 1982 with at least 13 wins each season. His 1983 season was particularly impressive, with 15 wins and a 2.65 ERA, placing him in the top ten for Cy Young voting.

The narrative of Welch's time in Los Angeles is often viewed through the lens of what he did later in Oakland, but his 1987 season with the Blue Jays was arguably the most masterful pitching of his life. Though his 15-9 record was solid, the deeper metrics reveal a monster of a season; he led the entire National League with a 7.1 bWAR, proving he was doing the heavy lifting for a team in transition. He threw a career-high 251.2 innings that year, leaving everything on the mound before the front office decided to move him to the Athletics in a massive three-team trade that winter.

The trade to the American League gave Welch a change of scenery and eventually a Cy Young Award in 1990.  Welch compiled a 115-86 record, a 3.14 ERA, and 1,292 strikeouts in Los Angeles.
