He immediately proved his dominance at the level, posting a remarkable 2.06 ERA and earning recognition as a Carolina League All-Star. The following year, Armstrong dealt with injuries early in the season but still managed to record a 4.14 ERA after returning to full health. In 2014, he pitched for the Akron RubberDucks of the Double-A Eastern League, where he continued to impress by earning Eastern League All-Star honors.
Following his standout 2014 campaign, the Indians added Armstrong to their 40-man roster, protecting him from the Rule 5 Draft. He spent 2015 with the Columbus Clippers of the Triple-A International League, further solidifying his credentials by earning a selection to the Triple-A All-Star Game. This strong minor league performance earned him his first major league call-up later that year.
Cleveland Indians (2015–2017)
The Cleveland Indians promoted Armstrong to the majors on August 8, 2015. He made his MLB debut that same night, pitching a scoreless ninth inning with two strikeouts against the Chicago White Sox. Armstrong finished his rookie season with an outstanding 2.25 ERA across eight appearances, showcasing the potential that justified his steady climb through the minor leagues. In 2016, he appeared in 10 games for Cleveland, logging a 2.53 ERA with seven strikeouts while continuing to refine his repertoire.
During the 2017 season, Armstrong appeared in 22 games for the Indians, recording a 4.38 ERA with 20 strikeouts over 24.2 innings pitched. While his ERA was slightly elevated compared to his first two seasons, he remained a dependable option out of the Cleveland bullpen. On December 13, 2017, the Indians traded Armstrong to the Seattle Mariners in exchange for international bonus pool money, ending his initial stint with the organization.
Seattle Mariners (2018–2019)
Armstrong joined the Seattle Mariners for the 2018 season and delivered one of his most dominant stretches as a professional. He posted a remarkable 1.23 ERA with 15 strikeouts in just 14.2 innings pitched, demonstrating exceptional command and stuff. However, his 2019 campaign was derailed early when he was placed on the disabled list on March 18, 2019, with an oblique injury. Upon returning, Armstrong struggled significantly, allowing 14.73 ERA in four appearances before the Mariners designated him for assignment on April 26, 2019.
Baltimore Orioles (2019–2021)
Two days after being designated by Seattle, Armstrong was claimed off waivers by the Baltimore Orioles on April 28, 2019. He stabilized his season with Baltimore, recording a 5.13 ERA in 51 appearances for the Orioles. In the shortened 2020 season, Armstrong was even more effective, posting a 1.80 ERA with 14 strikeouts and a 2-0 record across 15 innings pitched in 14 games. His strong performance earned him a trusted role in the Baltimore bullpen during a rebuilding period for the franchise.
The 2021 season proved challenging for Armstrong as he struggled to a 8.55 ERA in 20 appearances. The Orioles designated him for assignment on June 4, 2021, and he cleared waivers, being sent outright to the Triple-A Norfolk Tides on June 11. Rather than accept an outright assignment, Armstrong’s career took another turn when he was traded to the Tampa Bay Rays on July 30, 2021, for cash considerations.
Tampa Bay Rays (2021, 2022–2024)
After joining the Rays, Armstrong made an immediate impact. Tampa Bay selected his contract on August 17, 2021, and he appeared in 11 games, posting a 4.50 ERA with 22 strikeouts. He was designated for assignment again on September 12 and elected free agency after the season. However, Armstrong returned to Tampa Bay on a minor league deal in May 2022, eventually earning another major league roster spot.

On January 11, 2024, Armstrong signed a one-year, $2.05 million contract extension with the Rays. He appeared in 38 games, compiling a 5.40 ERA with 50 strikeouts over 46.2 innings before Tampa Bay traded him to the St. Louis Cardinals on July 30, 2024, in exchange for outfielder Dylan Carlson.
St. Louis Cardinals and Chicago Cubs (2024)
