[1] He attended Kell High School ('08) in Marietta, Georgia, where he played baseball on a team that went to the state playoffs three times.

[6][7] His junior year, he formed part of a tandem atop Alabama's starting rotation that helped lead the Crimson Tide back to the NCAA Super Regional.

[10] That earned him a promotion to the Reading Phillies of the Class AA Eastern League in August with whom he was 4–1 with a 3.53 ERA and 29 strikeouts in 352⁄3 innings.

[10][12] A column written years later noted, "At 22, he was seen as one of the most advanced pitching prospects in the organization, and a call-up to the big club seemed imminent for sometime in 2013 ...

"[13] Pitching for the Lehigh Valley IronPigs of the Class AAA International League, after pitching to a record of 2–7 with a 4.04 ERA and 49 strikeouts in 791⁄3 innings, Morgan suffered a torn rotator cuff in his left throwing shoulder in May 2013, which required surgery;[14] he did not undergo surgery, however, until January, and thus missed the 2014 season.

[16] Entering 2015 fully healthy with improved mechanics, Morgan looked to re-establish himself in the IronPigs' starting rotation before a potential call-up to the major leagues later in the season.

[8] His mediocre statistics notwithstanding, minor league talent evaluator Matt Winkelman commented that Morgan's "velocity [is] almost back and slider is almost there.

Morgan considered retiring and moving to Atlanta to become a firefighter, but reported to Lehigh Valley and returned to the major leagues briefly in May and again in June for the rest of the season.

[27] In 2019, he was 3–3 with a 3.94 ERA along with 29 strikeouts in 292⁄3 innings for the Phillies, and ended his season early on the injured list with a left hip flexor strain.

On October 29, 2020, Morgan was outrighted off of the 40-man roster after having surgery to repair an injury he received on the flexor pronator in his throwing arm, and he elected free agency the next day.

[28][29] On January 3, 2021, Morgan signed a minor league contract with the Chicago Cubs organization that included an invitation to Spring Training.

[30] On June 29, Morgan was selected to the active roster posting a 2–1 record in 34 games, a 4.26 ERA with 28 strikeouts along with 2 saves in 251⁄3 innings.

Morgan has used his slider to generate a large majority of his swings and misses since 2017 as well as striking out higher percentage of batters he faced as reliever than as a starter.
