Colorado Rockies Era (2016–2022)
Estévez received his promotion to the major leagues on April 22, 2016, and made his MLB debut the following day. When Rockies closer Jake McGee went on the disabled list in June, Estévez stepped into the closer role. He finished his rookie season with a 3-7 record, 63 appearances, 11 saves, and a 5.24 earned run average.

Unfortunately, Estévez missed the entire 2018 season due to several injuries, remaining with the Triple-A Albuquerque Isotopes. He returned in 2019 with a strong bounce-back performance, posting a 3.75 ERA with 81 strikeouts in 71 games. His 2020 performance regressed as he allowed 21 runs in 24 innings pitched, finishing 1-3 with a 7.50 ERA. In 2021, Estévez appeared in 64 games with a 3-5 record, a 4.38 ERA, and 11 saves.

In Game 4 of the 2024 National League Division Series against the New York Mets, Estévez entered in the bottom of the sixth inning with the bases loaded and surrendered a grand slam to Mets shortstop Francisco Lindor, giving New York a 4-1 lead that held as the final score.
