He currently rides for the Monster Energy Pro Circuit Kawasaki team, but has also competed for GEICO Honda and Troy Lee Designs Red Bull KTM during his professional career.
Whilst recovering from the hand injury, McAdoo was signed by the factory GEICO Honda team as a replacement rider for the injured RJ Hampshire and Chase Sexton.
His season in the 250 class of the AMA Motocross Championship was cut short after a shoulder injury sustained training in the week following the second round.
At the end of the season, McAdoo was drafted into the Penrite Honda Team for the final round of the Australian Supercross Championship, where he won the SX2 class.
Competing in the 250SX West class, he finished inside the top-ten in all but one event and at the final round achieved his first professional podium with third in Las Vegas.
He was eventually picked up by the Troy Lee Designs Red Bull KTM team to ride in the 2019 AMA National Motocross Championship from the fourth round onwards.
Following this, McAdoo was able to finish ninth in the final standings of the 250 class in the AMA Motocross Championship, becoming a consistent feature in the top-ten and recording a fourth overall at round two as his standout result.
[11] This win also resulted in him gaining the championship lead following the event for the first time and a further four podiums across the remaining rounds saw him finish third in the final standings behind Justin Cooper and Hunter Lawrence.
He then crashed a round later in Nashville with his Pro Circuit teammate Levi Kitchen, sustaining a broken scapula and a partial shoulder muscle tear which ended his supercross season.
