Stajduhar was loaned out again on March 15, 2019, to USL Championship side Tulsa Roughnecks for their 2019 season. He made his professional debut on March 29 in a 2–1 win over RGV Toros. He was briefly recalled by Orlando City on June 24 owing to Greg Ranjitsingh's participation in the 2019 CONCACAF Gold Cup and an injury to Adam Grinwis before returning to Tulsa in July. In July 2019, Stajduhar was selected to take part in the MLS Homegrown Game. Having had his original contract option declined at the end of the season, Stajduhar renegotiated a new one-year deal with Orlando ahead of the 2020 season.
