Mercury bring back Kiana Williams on developmental contract

The move allows Phoenix to keep a player who is already familiar with coach Nate Tibbetts’ system and coaching staff while maintaining roster flexibility. In a corresponding move, guard Shay Ciezki was released from her developmental contract.

Williams has spent parts of the past two seasons with the Mercury and has established herself as a dependable depth option in the backcourt.

The guard appeared in eight games for Phoenix before being waived, averaging 4.8 points in 13.1 minutes per game while shooting 36.4% from the field.

Those numbers came in a limited sample, but they reflect the type of production Williams can provide in a reserve role. Her ability to space the floor and contribute without an extended adjustment period offers added value for a veteran team with postseason aspirations.

The signing also helps preserve organizational depth. Players on developmental contracts can be activated for up to 12 games during the season, giving teams flexibility when navigating injuries, scheduling demands and roster needs.

For Phoenix, the move keeps a familiar option in-house. Williams already understands the Mercury’s system and personnel, allowing her to step into a rotation role with minimal adjustment if needed over the course of the season.
