Chicago SkyvsPhoenix Mercury

This is a WNBA regular-season meeting between the Chicago Sky and the Phoenix Mercury at Wintrust Arena. The most important number on the page is the model's win probability: Chicago are given a 64.8% chance of winning, against 35.2% for Phoenix, with a projected scoreline of 91-87.

The two teams arrive in similar shape from a results standpoint. Across their last 20 relevant splits — Chicago at home, Phoenix on the road — both have identical 8-12 records and 40% win rates. The difference lies in scoring output: Chicago average 88.6 points at home while Phoenix average 81.5 on the road.

Chicago's home form over their last 20 games at Wintrust shows 8 wins and 12 losses, a 40% win rate. Their scoring average at home is 88.6 points per game with 88.15 conceded, leaving a marginal positive differential of 0.45 points per game.

Looking at their last five matches in all venues, the Sky went WWLLW, averaging 91.8 points scored and 88.2 conceded. That recent run is slightly more productive than their home baseline, particularly on the offensive end. They were last in action on 2026-08-01, three days before this fixture, a short turnaround flagged as congested.

Phoenix's away form over the last 20 road games contains the same 8-12 record and 40% win rate as Chicago's home mark. The scoring profile is weaker: 81.5 points scored and 84.3 conceded per game, a negative differential of 2.8 points.

The Mercury's last five games overall produced a LWWWL sequence, with averages of 84.8 points scored and conceded — a perfectly balanced recent profile. They also played on 2026-08-01, meaning both teams enter on three days' rest with no freshness advantage either way.

Seven meetings between these sides are on record, and Phoenix have won six of them. Chicago's lone victory came in the most recent fixture on 2026-07-08, a 77-66 win on Phoenix's home floor.

Across the seven games, Chicago scored 585 total points to Phoenix's 632, an average of 173.86 points per meeting. Every meeting produced more than two total points. In the two meetings played at Chicago, Phoenix won both; in the five at Phoenix, Chicago won one and lost four.

The venue is Wintrust Arena, where Chicago's home record over the last 20 games is 8-12. That is identical in record and win rate to Phoenix's 20-game road mark, making the surface-level results symmetrical.

The scoring profiles diverge, though. Chicago's home scoring average of 88.6 is more than seven points higher than Phoenix's road average of 81.5, and the home side's conceded average (88.15) is also higher than Phoenix's (84.3). The model's projected score of 91 for Chicago reflects that home offensive output, while Phoenix are projected at 87.

Both teams enter on a three-day turnaround, flagged in the data as a congested short rest. Neither side carries an extra rest advantage. No league table data is provided for either team, so positional context is unavailable.

The model rates this at medium confidence, with Chicago's win probability at 64.8%. Interestingly, the two teams share an identical 40% win rate in the relevant splits, yet the projected margin is 4.3 points in Chicago's favor. That gap is driven by the scoring numbers: Chicago's home offensive output exceeds Phoenix's road scoring by roughly seven points per game.

The normal-distribution margin model projects a Chicago win with 64.8% probability and a Phoenix win with 35.2%. The expected values are 90.8 points for Chicago and 86.5 for Phoenix, rounding to a 91-87 projected scoreline and a margin of 4.3 points.

The model's confidence is medium, meaning the projection is not tight but the direction is clear. The model flags Chicago's win as the most likely outcome, and it implies a combined expected total of roughly 177 points. No other outcome is presented as the most likely one.

The data collectively points to a Chicago home win. The Sky are stronger on their own floor, the model gives them a clear probability edge, and they won the most recent head-to-head meeting. The congestion affects both teams equally, so it does not tilt the projection.

The main argument for Phoenix is the historical record: six wins in seven meetings, including two wins in Chicago. If that pattern reasserts itself, or if Phoenix's recent balanced scoring (84.8 scored and conceded over their last five) holds Chicago's offense below its home average, the upset becomes plausible. On balance, the model's medium-confidence lean to Chicago is the headline.
