Rivers had an encouraging rookie season after being selected by the Sun with the No. 8 overall pick in the 2025 WNBA Draft, and she ended the year with a flourish by posting back-to-back 16-point performances. Although the Sun struggled to rack up wins in 2025, Rivers established herself as a solid building block for the team, averaging 8.8 points, 2.8 rebounds, 2.7 assists, 1.5 steals and 0.9 blocks in 26.1 minutes per game. She appeared mainly off the bench over the final month of the regular season, but it wouldn't be surprising to see her back in the mix for a starting role in 2026 now that she has a full year of professional experience.
