What happened: The Phoenix Mercury have officially signed guard Kiana Williams to a developmental contract. In a corresponding move, the franchise announced the release of guard Shay Ciezki from her own developmental deal.

Why it matters: The transaction gives the Mercury a fresh look at the guard position as they evaluate their backcourt depth during the early stretch of the 2026 WNBA regular season. Developmental contracts offer franchises low-risk opportunities to cycle through young talent without committing a permanent roster spot.

What to watch: Williams will immediately join the team's developmental program and look to impress the coaching staff for a potential standard contract down the line.
