Simonsen's first PBA Tour title came on December 18, 2015 at the Mark Roth/Marshall Holman PBA Doubles Championship, where he teamed with Connor Pickford. (
This was considered a 2016 season title.)
The victory made Simonsen the second-youngest winner of a standard PBA Tour event, just two days over the all-time record of 18 years, 11 months and 12 days set by Norm Duke in a 1983 tournament.

Simonsen made history on February 14, 2016, when he won his first PBA Tour singles title and first major at the USBC Masters in Indianapolis.
This win made Anthony the youngest player ever, at 19 years, 1 month and 8 days of age, to win a PBA major title.
 PBA Hall of Famer Mike Aulby had held this distinction since 1979, when he won the PBA National Championship at age 19 years, 83 days.
Simonsen qualified for two more televised finals in major tournaments during 2016, finishing fourth at the U.S. Open in November and fifth at the PBA World Championship in December.
He appeared in the championship round (the final stage of a tournament) seven times this season.
