He was recalled hours ahead of the June 24 game against San Jose and was immediately placed in the starting line-up, scoring both goals in a 2–1 win over San Jose Earthquakes, which landed him on the MLS Team of Matchday 21.[24][25] Adeniran continued to produce at an effective strike rate for the rest of the 2023 season.
