He made his professional debut that season with the Dominican Summer League Rays and spent the whole season there, going 3–3 with a 3.96 ERA in 25 innings. In 2015, he played for both the Hudson Valley Renegades and Bowling Green Hot Rods, compiling a combined 1–2 record and 3.03 ERA in 18 relief appearances.

He was named the Rays' minor league reliever of the year after posting a 2.76 earned run average (ERA) with 90 strikeouts and 15 saves in 71.2 innings pitched.[2] The Rays added him to their 40-man roster after the season.[3] He began the 2018 season with the Durham Bulls.
Castillo was promoted to the Tampa Bay Rays and made his debut on June 6, 2018.[4] For the season, he split time between the bullpen and being one of the Rays' "opening" starters. Castillo threw 56+2⁄3 innings over 43 games, going 4–2 over 11 starts. He finished the year with a 3.18 ERA, 65 strikeouts and 18 walks.
In 2019, Castillo was used as both a closer and opener. On June 23, he was put on the 10-day injured list with shoulder inflammation.[5] He finished the season appearing in 65 games (6 starts). In 68+2⁄3 innings, he recorded 81 strikeouts, 8 saves, and an ERA of 3.41.[6] In the postseason, Castillo threw 2 shutout innings in the American League Wild Card victory the Oakland Athletics.[6] He threw 3+2⁄3 innings over three games (one start) in the American League Division Series, where the Rays lost to the Houston Astros in five games.[6]
In 2020, Castillo was moved away from the opener role. On July 24, he went on paternity leave.[5] Castillo collected 4 saves over 22 games, posting an ERA of 1.66 with 23 strikeouts and 11 walks.[5] In the postseason, he was used in late innings consistently when the Rays had the lead. He pitched the final two innings of Game 5 of the ALDS against the New York Yankees, picking up the win after Mike Brosseau's 8th inning home run. In the American League Championship Series against the Astros, Castillo appeared in 7 games, going 1–0 with 2 saves and 2 holds.[7] The first run he allowed was in Game 6.[7]
On July 7, 2021, Castillo combined with Collin McHugh, Josh Fleming, Matt Wisler, and Peter Fairbanks to no–hit the Cleveland Indians. However, since the feat was achieved in a truncated seven–inning doubleheader game, it was not recorded as an official no-hitter.[8]
On July 29, 2021, the Rays traded Castillo to the Seattle Mariners for J. T. Chargois and Austin Shenton.[9] He made 24 appearances for Seattle down the stretch, registering a 3-1 record and 2.86 ERA with 26 strikeouts and 2 saves in 22.0 innings pitched.

On October 9, Castillo elected free agency.[11]
