Point guard Courtney Vandersloot, who last year helped the Chicago Sky win their first WNBA championship, agreed to a one-year deal to return to the team, ESPN reported Friday.
Vandersloot, 33, tested the free-agent market for the first time since the Sky selected her with the third pick in the 2011 draft out of Gonzaga.
A three-time All-Star and two-time All-WNBA First Team selection, Vandersloot has led the league in assists the last four seasons and averaged at least 8.1 over the last five, including a career-high 10 in 2020. She ranks fourth on the all-time assists list with 2,178 and has career averages of 10.1 points, 6.7 assists and 1.3 steals in 11 seasons.
Vandersloot set the single-game record with 18 assists against the Indiana Fever in August 2020 and tied the mark in the series opener against the Connecticut Sun in September 2021 — a game in which she recorded the second triple-double in WNBA playoff history.
The move was the latest in a busy offseason for the Sky.
They brought back 2021 WNBA Finals MVP Kahleah Copper on a two-year deal.
They acquired Julie Allemand from the Mercury in a three-team deal that sent Diamond DeShields to Phoenix.
After Stefanie Dolson left for the New York Liberty, the Sky signed Emma Meesseman.
