Chicago Sky101-106Phoenix Mercury

Chicago Sky host Phoenix Mercury at Wintrust Arena in a WNBA matchup where the model strongly favours the home side. The projection gives Chicago a 64.8% win probability and an expected score of 91-87, a margin of 4.3 points. Both teams enter the game on three days' rest after playing on August 1, making this a congested fixture for both rosters.

The head-to-head record is lopsided, with Phoenix winning six of seven meetings. However, Chicago took the most recent encounter, a 77-66 decision in Phoenix on July 8. That result, combined with the model's lean toward Chicago, makes this a fixture where the historical pattern and the current projection point in opposite directions.

The season table standings are not listed for either side, so the available data is limited to home/away splits, recent form, and the model output.

Chicago's home numbers over their last 20 games show an 8-12 record, a 40% win rate, with 88.6 points scored and 88.15 points allowed per game. In their last five games overall, the Sky have gone WWLLW, averaging 91.8 points scored and 88.2 points allowed. The most recent of those five games, on August 1, was a victory.

The recent five-game scoring average of 91.8 is 3.2 points higher than Chicago's home scoring average of 88.6, while the recent defensive average of 88.2 is essentially unchanged from the home defensive mark of 88.15. The model projects Chicago to score 90.8, which sits between those two scoring figures.

Phoenix's road record over their last 20 away games is also 8 wins and 12 losses, a 40% win rate identical to Chicago's home mark. They have averaged 81.5 points scored and 84.3 points allowed on the road, giving them a negative differential of 2.8 points. Their recent five-game form across all venues is LWWWL, with an average of 84.8 points on both offense and defense.

The Mercury's most recent game on August 1 was a loss, according to the form sequence. The team's road scoring average of 81.5 is 3.3 points lower than their recent overall scoring average of 84.8, while their road defensive average of 84.3 is 0.5 points lower than the recent defensive mark. The model projects Phoenix to score 86.5, above both their road and recent scoring averages.

The seven meetings on record between these teams have produced a clear pattern: Phoenix has won six and lost one. The Mercury have outscored the Sky 632-585 over those games, an average of 90.3 points per game for Phoenix and 83.6 for Chicago. The combined totals have averaged 173.86 points per game.

Chicago's lone victory came in the most recent meeting, a 77-66 road win on July 8, 2026. The six Phoenix wins were by margins of 4, 4, 5, 8, 16, and 21 points. The record shows that Phoenix has typically held the upper hand in this matchup, though the sample is limited to seven games.

The home and away splits show both teams with identical win rates: Chicago has won 40% at home, and Phoenix has won 40% on the road. The scoring differentials differ, with Chicago at a +0.45 points-per-game margin at home (88.6 scored, 88.15 allowed) and Phoenix at -2.8 on the road (81.5 scored, 84.3 allowed).

That leaves a 7.1-point gap between Chicago's home scoring average and Phoenix's road scoring average. The model's projected margin of 4.3 is lower than that gap, suggesting the model weighs other factors beyond the raw venue splits. Neither team has a rest edge, as both played on August 1 and are on three days' rest.

The congested schedule is the most notable factor in the data. Both teams are playing three days after their last match, so there is no recovery advantage for either side. The model's confidence is medium, indicating the probability split is not a near-certainty. The head-to-head record, while small, is strongly in Phoenix's favour, but the most recent meeting went to Chicago.

No other scheduling or external factors are provided in the data. The key inputs are the home/away splits, the recent five-game form, and the model projections, which collectively favour Chicago.

The normal-distribution margin model assigns a 64.8% win probability to Chicago and 35.2% to Phoenix. The expected score is 91-87, producing a projected margin of 4.3 points and a combined total of 178 points. That total is slightly above the 173.86 average from the seven head-to-head meetings.

The model's medium confidence suggests a realistic range of outcomes around the projection. The projected home score of 90.8 is close to Chicago's recent five-game scoring average of 91.8, while the projected away score of 86.5 is above Phoenix's recent average of 84.8 and their road average of 81.5. This aligns with Chicago's higher recent scoring output.

The data points to a Chicago Sky victory, with the model giving them a 64.8% chance and a projected 4.3-point margin. Chicago's home scoring average and recent form exceed Phoenix's road numbers, and the Sky won the most recent head-to-head meeting. However, Phoenix has won six of the seven prior meetings, so the historical balance favours the visitors.

The projection would be off if Phoenix defends at its road standard of 84.3 points allowed and Chicago falls short of its recent scoring output, or if Phoenix's offence exceeds its recent average. The model's medium confidence leaves room for a Phoenix win, but the expected outcome is a narrow Chicago victory.
