In 2021, Christian began his open wheel career. He spent the off season testing in different cars and tracks and learned from each experience. He participated in the Yacademy Winter Series in a Ligier JSF4. This allowed him a ton of seat time and prepared him for the FRP Eastern Pro 4 Challenge where he won his first Championship with seven pole positions, two second place results and six wins. Not wanting to sit still, he hopped in his father’s Pro 1340 SR3 Radical at Road America in the Blue Marble Radical Cup North America. His debut brought him three pole positions poles and two race wins, making him the youngest race winner in Radical Cup history.
