When Jon Gray was selected third overall in 2013, he carried the immense weight of being the "Gray Wolf”, the power-armed savior meant to lead the Colorado rotation for a generation. While the high altitude of Denver often made for a bumpy ride, Gray’s time in purple was defined by flashes of pure, unadulterated dominance that few in franchise history have ever replicated.

Gray’s stay in Denver was marked by a relentless ability to miss bats, a trait that allowed him to rewrite the franchise record books early in his career. He established himself as a model of consistency between 2016 and 2019, securing at least 10 victories in four consecutive seasons. On September 17, 2016, against the Padres, Gray struck out a franchise-record 16 batters in a complete-game shutout. It was the most strikeouts ever recorded in a single game at Coors Field, surpassing the mark held by the legendary Randy Johnson and proving that Gray’s stuff could neutralize even the most hitter-friendly environment.

While his ERA occasionally fluctuated, Gray remained a high-frequency producer of strikeouts, three times surpassing the 150-strikeout plateau during his initial four-year run. He possessed a specialized ability to generate swings and misses, using a 95-plus-mph fastball and a sharp, late-breaking slider to lead the staff in strikeouts for multiple seasons. He served as a primary engine for the 2017 and 2018 squads that made back-to-back postseason appearances, providing the high-leverage production required to anchor the rotation during the club's most successful recent era.

After the 2021 season, he signed with the Texas Rangers as a free agent. With the  Rockies, Gray compiled 53 wins and 849 strikeouts.

Kyle Freeland’s path to the purple pinstripes was a genuine "full-circle" moment for the franchise. Born in Denver just weeks after the Rockies played their inaugural game, he was famously selected by his hometown club as the 8th overall pick in the 2014 Amateur Draft out of the University of Evansville. This wasn't his first brush with the draft; the Philadelphia Phillies had previously taken a flyer on him in the 35th round in 2011, but he opted to attend college to refine his craft. That decision paid dividends when he returned to Colorado with a polished, high-velocity repertoire, surfacing in 2017 and maturing instantly to finish seventh in the Rookie of the Year race.

The true breakthrough arrived during a historic second act that etched his name into the annals of the sport. He reached a breathtaking crescendo in 2018, authoring a campaign that remains the gold standard for Colorado pitching. That summer, he posted a 17-7 record with a franchise-record 2.85 ERA, a feat made even more incredible by his 2.40 ERA at home—the lowest in Coors Field history. He was a model of specialized composure, finishing fourth in the National League Cy Young voting and leading the club to a historic Wild Card victory over the Cubs with 6.2 shutout innings at Wrigley Field.

The most challenging aspect of his journey has been the search for that lost magic in the years that followed. Freeland has been a master of resilience, battling back from a 2019 season in which his ERA ballooned and led to a temporary demotion to the minors. Nevertheless, he remains a high-frequency workhorse who recently eclipsed 1,200 career innings, continuing to take the ball every fifth day as the emotional heartbeat of the clubhouse.

With the Rockies, Freeland has compiled 65 wins, 944 strikeouts, and over 1,260 innings pitched across 236 games.

German Márquez established himself as a frontline starter in 2017, but it was his second season that he reached his peak. That season remains a pillar of club history; he captured a Silver Slugger and finished sixth in bWAR for pitchers, proving that his high-velocity fastball could neutralize any lineup regardless of altitude. He was a model of specialized athleticism, a high-frequency winner who seemed destined to rewrite every pitching record in the Mountain West. His craftsmanship was punctuated by a 2021 All-Star nod, a moment that served as the high-water mark for his tenure in the purple pinstripes.

The latter half of his journey, however, was defined by a frustrating search for that lost magic. Márquez possessed a specialized "bulldog" mentality, but the physical demands of pitching in thin air, coupled with a major elbow injury that sidelined him, began to erode his statistical dominance. His final seasons in Colorado were a grueling grind; his once-elite efficiency wavered, and his ERA climbed as he struggled to maintain his rhythm between stints on the IL.

Following the 2025 Season, Marquez signed with the San Diego Padres as a Free Agent.  With the Rockies, Márquez compiled 65 wins and a franchise-record 983 strikeouts.
