In 2016, as a sophomore, he was batting.324 with three home runs and 21 RBI in 30 games before an injury ended his season. He returned from the injury that summer and played for the Keene Swamp Bats where he hit.264 with five home runs and 19 RBI in 42 games. As a junior in 2017, he batted.296 with nine home runs and 52 RBI in 58 games.
Seattle Mariners
After his junior year, Costello was selected by the Seattle Mariners in the 31st round of the 2017 MLB draft. He signed for $5,000 and made his professional debut that year for the rookie–level Arizona League Mariners, batting.331/.430/.634 with eight home runs and 38 RBI in 44 games. He began 2018 with the Single–A Clinton LumberKings, with whom he was named to the Midwest League All-Star Game where he participated in the Home Run Derby.
Minnesota Twins
On July 30, 2018, Costello was traded to the Minnesota Twins in exchange for Zach Duke. He was assigned to their minor league affiliate, High–A Fort Myers Miracle, and finished the season there. In 128 games between Clinton and Fort Myers, he hit.258 with twenty home runs and 79 RBI. He returned to Fort Myers to begin 2019, and was later promoted to the Double–A Pensacola Blue Wahoos during the season. Over 108 games between the two affiliates, Costello batted.223/.343./412 with 15 home runs and 46 RBI.
Death
Costello died on November 18, 2019, in Auckland, New Zealand, while preparing to start the Australian Baseball League season with the Auckland Tuatara. He was 23 years old. Costello was found dead in his hotel room bed by teammates. An autopsy revealed that he died of sudden cardiac arrhythmia. In February 2022, his parents filed a wrongful death lawsuit against the physician who conducted Costello's preseason physical, alleging that he intentionally ignored ECG results showing that Costello had Wolff–Parkinson–White syndrome which likely caused the sudden cardiac arrhythmia that led to his death.
