Philadelphia Phillies Breakthrough (2020–2022)
Moniak was added to the Philadelphia Phillies’ 40-man roster and promoted to the major leagues on September 16, 2020, making his MLB debut that night as a ninth-inning pinch runner at Citizens Bank Park. He recorded his first major league hit two days later with a single against the Toronto Blue Jays.
Moniak hit his first major league home run on April 21, 2021, against Anthony DeSclafani of the San Francisco Giants.

Los Angeles Angels Breakthrough (2022–2024)
On August 2, 2022, Moniak was traded to the Los Angeles Angels alongside prospect Jadiel Sanchez in exchange for starting pitcher Noah Syndergaard. He debuted for the Angels the following day and produced an early run of offense, including a pair of home runs in his first week with the club.

He began 2023 at Triple-A Salt Lake before being recalled in May and finished the year having hit .280 with 14 home runs and 45 RBIs in 85 games after the recall. In 2024 he played in 124 games for the Angels and totaled 14 home runs and 49 RBIs before being released in March 2025.
