In 2019, pitching for the Class AA Reading Fightin Phils and the Class AAA Lehigh Valley IronPigs, he was 3-2 with two saves and a 6.50 ERA over 36 innings.

Hammer was called up to the major leagues for the first time on May 25, 2019. He made his debut a day later at Miller Park against the Milwaukee Brewers. In 2019 with the Phillies he was 1-0 with a 3.79 ERA over 19 innings. Hammer was designated by assignment for the Phillies on February 5, 2020.

Hammer’s fastball, which reaches 96 mph, is his best pitch. He also throws a slider and a changeup.

In 2018, while pitching for three minor league teams (the GCL Phillies West and GCL Phillies East of the Rookie Gulf Coast League, and the Clearwater Threshers), Hammer was 1-2, with a 2.63 ERA, in 12 games (his number of appearances limited due to an elbow strain), posting 17 strikeouts, in 13.2 innings. Pitching for Philadelphia's Reading Fightin Phils in the AA Eastern League and the Lehigh Valley IronPigs in the AAA International League in 2019 (prior to his major league call-up), Hammer was 2-0, with a 1.61 ERA, 0.94 WHIP, accumulated a combined 29 strikeouts, in 22.1 innings.

On July 26, 2017, the Rockies traded Hammer, shortstop Jose Gomez, and pitcher Alejandro Requena to the Philadelphia Phillies, for Pat Neshek. He was named a South Atlantic League 2017 Mid-Season All Star. Pitching in 2017 for three Class A minor league teams (the Lancaster JetHawks of the California League, the Asheville Tourists of the South Atlantic League, and the Clearwater Threshers of the Florida State League), Hammer totaled a 6-2 win–loss record, with a 1.87 ERA, appearing in 48 games, with 85 strikeouts, in 57.2 innings; he saved 13 games, in 14 save opportunities, had a 0.88 WHIP, and held hitters to a .175 batting average.

In the fall of 2017, while playing for the Glendale Desert Dogs in the Arizona Fall League, Hammer was named an AFL Mid-Season All Star, and named to the AFL All-Prospect Team and Rising Stars after posting an 0.66 ERA in 10 games.

Pitching in 2016 for the Grand Junction Rockies in the Rookie Pioneer League, Hammer was 0-2, with a 3.92 ERA, in 27 games, notching 52 strikeouts, in 43.2 innings pitched.

That season, Hammer had difficulties seeing (both) the catcher and home plate, because of his poor eyesight; so, after the 2016 season, he picked out a pair of glasses with thick black plastic frames, to be worn while on the field. Apart from Hammer‘s pitching abilities, he is known for those signature black big-framed glasses, (naturally) drawing comparison to those of Ricky (Wild Thing) Vaughn, a character in the movie Major League (as portrayed by Charlie Sheen). Hammer chose glasses over contacts because contacts burned his eyes, and said:

Hammer played college baseball first for two years at Navarro College in Texas where, converted from shortstop to pitcher, he had a 1.09 earned run average (ERA) and was named a JuCo Academic All-American and 2014 All-Region XIV. He then played for two years at Marshall University in West Virginia, majoring in Health Sciences and graduating in 2016. He was drafted by the Colorado Rockies in the 24th round (710th pick overall) of the 2016 Major League Baseball draft. His signing bonus was $1,000.
