Pitcher Germán Márquez was signed by the Tampa Bay Rays as an amateur free agent before the 2012 season. The scout was Ronnie Blanco. He spent that year with the VSL Rays, going 0-2, 6.82 in 15 games, including 6 starts. In 2013, he moved to the Princeton Rays of the Appalachian League where hes record improved to 2-5, 4.05 in 12 starts. He gave up only 46 hits in 53 1/3 innings, but struggled with his control, with a 38/20 K/W ratio. In 2014, he moved up to the Bowling Green Hot Rods of the Midwest League. His record there was 5-7, 3.21, and he improved his K/W numbers significantly, to 95/29 in 98 innings. He was with the Charlotte Stone Crabs of the Florida State League in 2015. While his won/loss record was only 7-13, his ERA was a decent 3.56, he pitched a career-high 139 innings in 26 games and struck out 104 while keeping his walks at 29.
On January 28, 2016, he was included in a major league trade, joining reliever Jake McGee in heading to the Colorado Rockies, in return for OF Corey Dickerson and 3B Kevin Padlo. He was named the Eastern League Pitcher of the Year after going 9-6, 2.85 in 21 games for the Hartford Yard Goats of the AA Eastern League. He reached the majors that September, going 1-1, 5.23 in games with the Rockies. In 2017, he was added to the team's starting rotation in late April after starting the year in the minors and in his fourth start on May 10th, he pitched a gem. He held the Chicago Cubs hitless until Kris Bryant doubled to lead off the 7th and ended up giving up no runs on 3 hits in 8 innings while walking 1 and striking out 8. He was given credit for Colorado's 3-0 win and also collected his first major league hit, a two-run single in the 7th.
He hit his first career homer on July 11, 2018, off position player Daniel Descalso of the Arizona Diamondbacks. It came in a 19-2 beatdown of the D-Backs in which Descalso and C Alex Avila combined to pitch the final 4 2/3 innings. On September 26th, with the Rockies in the heat of a division race with the Dodgers, he struck out the first 8 Philadelphia Phillies batters he faced on his way to a 14-0 win. The 8 strikeouts tied the modern major league record shared by Jim Deshaies and Jacob deGrom, and he also reached 221 strikeouts on the season, erasing Ubaldo Jimenez's club record of 214 set in 2010. Pitcher Nick Pivetta broke the string of K's with a comebacker to the mound in the bottom of the 3rd. Marquez pitched 7 scoreless innings in the game. He started the one-game playoff against the Los Angeles Dodgers on October 1st, but lost that game after allowing a pair of two-run homers. Still, he finished the season with a record of 14-11, 3.77 and 230 Ks. He was also name the National League Pitcher of the Month for September in recognition of his 3-2 record, 2.35 ERA and especially his 57 Ks in 38 1/3 innings. He lost his only start of the postseason, in Game 3 of the Division Series against the Milwaukee Brewers on October 7th as he gave up 2 runs in 5 innings and Colorado was shut out, 6-0.
On April 6, 2019, the Rockies signed him to a five-year contract extension worth $43 million. On April 14th, he became the first major league pitcher to throw a complete game that season, as he tossed a one-hitter to defeat the San Francisco Giants, 4-0. It was also his first career shutout, and his first complete game as a professional, as he had never managed one in the minors either. He had a no-hitter until one out in the 8th, when Evan Longoria managed to line a single just past the reach of 3B Nolan Arenado.
On June 29, 2021, he pitched one of the greatest games ever at Coors Field, firing a one-hitter in shutting out the Pittsburgh Pirates, 8-0. He was only the fourth pitcher in the ballpark's history to limit opponents to one hit or less in a complete game, with Hideo Nomo having pitched a no-hitter; the other two members of that very exclusive club were Pat Rapp and Roy Oswalt. He actually had a no-hitter until the 9th, when rookie Ka'ai Tom hit a lead-off single, and he ended up facing only one batter over the minimum. He had given a preview of this performance only two weeks earlier, on June 17th, when he had held the Milwaukee Brewers to one hit over six innings before having to leave due to soreness in his back.
