The WNBA Commissioner’s Cup round-robin ends with New York favored heavily over Chicago at Wintrust Arena, where Breanna Stewart’s points prop sits at 19.5 and the Liberty list multiple scoring levers while the Sky manage injuries.
New York arrives at Wintrust Arena with the kind of matchup that feels like it could tilt quickly—because the Chicago Sky have struggled, and the Liberty are built to punish teams that can’t hold their defensive shape.
The WNBA Commissioner’s Cup round-robin phase wraps up on Wednesday, June 17, 2026, and the spotlight lands on Breanna Stewart as New York seeks to dismantle a Chicago side carrying major absences. The game tips at 8:00 p.m. ET, with TV coverage listed for WCIU and WNYW.
Stewart’s nights don’t usually disappear for long. After a rare off-night in the scoring column. the Liberty star is posted with an over/under of o19.5 points scored at -112. The case for the bounce-back begins with her season usage and where her scoring comes from—Stewart leads New York with a 27.1% usage rate and generates 34.8% of her scoring from the free-throw line.
Those numbers matter against a Chicago team that commits 21.0 personal fouls per game and allows 24 free throws per game. In the betting setup. that combination is exactly what keeps the scoring prop from feeling like guesswork: if New York attacks. Stewart’s role is built into the possessions that end at the line.
The Liberty’s offensive spacing is also part of the reasoning. Sabrina Ionescu is back to stretch the floor, and the expectation is that it limits double teams—creating scoring opportunities for Stewart. The article notes that Stewart is playable to Over 20.5 points as well.
There’s also a reminder that Stewart doesn’t have to score in exactly the same rhythm as before. The write-up points to her 14-point performance against Washington, but argues it shouldn’t fool anyone into thinking her scoring is capped—especially in a matchup framed as a mismatch.
On the other side, Chicago’s hope runs through Skylar Diggins, described as the engine of the Sky. She has scored at least 16 points in three of her previous four games and, in the prediction, is expected to find success against a Liberty defense that allows 40 points per game to guards.
If the Liberty do what they’re expected to do, the question becomes whether the Sky can keep their main scorer from getting dragged down. In the prop list, Diggins is placed at Over 15.5 points.
Sabrina Ionescu’s return is its own storyline in the preview. The piece says she returned to the lineup and promptly went 0-2 from downtown, with 26 minutes of playing time. But because it’s a career 35% shooter. the prediction treats that early rough patch as something that can swing quickly—especially with Stewie going off. The same-game parlay listed in the preview includes Ionescu at Over 1.5 threes.
New York vs. Chicago is priced like a statement. The listed spread is New York -8.5 (-105) with Chicago +8.5 (-115), and the moneyline shows New York -350 and Chicago +275. The over/under is set at Over 169.5 | Under 169.5.
Recent form inside the numbers is also part of the betting pitch: the Liberty are 7-3 ATS in their last 10 games.
The preview also lays out a same-game parlay built around three scoring targets:
Breanna Stewart Over 19.5 points
Sabrina Ionescu Over 1.5 threes
Skylar Diggins Over 15.5 points
A separate results note credits Phil Naessens with a “2026 Transparency Record,” listing Best bet: 6-5, +0.81 units, and SGP: 2-9, -1.80 units.
Injuries add another layer to how the matchup could play. The Liberty injury list shows Betnijah Laney-Hamilton (Questionable). The Sky injury report is longer, with Courtney Verdersloot (Out) and DiJonai Carrington (Out). The preview also flags that odds are correct at the time of publishing and subject to change. and it notes the content is not intended for use in MA.
By the time tip-off arrives. the story will likely be decided by the same thing the preview keeps circling: can Chicago slow the Liberty long enough to avoid putting Stewart at the free-throw line again and again. If it can’t. New York’s favorite role doesn’t look like a short-term bet—it looks like a script.
