Ultsch is entering his 6th year of professional baseball after graduating from Puget Sound as a two-way player. The 6-4 slugger started his career in the Pacific Association in 2019, then jumped to the Utica Unicorns in the United Shore Baseball League, and then spending the last three years in Pioneer League. 

In 2022, Ultsch played in just 21 games with the Billings Mustangs and performed well, by next season he was with a new club, the Ogden Raptors. He broke out in 2023, where in 89 games he had a team-leading .373 average, belted 7 home runs, and drove in 73. 

This past season, the California native continued where he left off from the year prior. Ultsch contributed with 10 bombs, 21 doubles, and set a new career-high in RBIs with 86. He played in 83 games with Ogden before being dealt to the Boise Hawks in late August and was named to the Pioneer League All-Star team.
