As the WNBA season races toward its thrilling conclusion, September 21 features two marquee matchups that promise to keep fans on the edge of their seats. Both games have playoff implications, star power, and the kind of drama that makes basketball such a beloved sport.

Atlanta Dream are poised to clash with the New York Liberty in a showdown that could very well be a playoff preview. The Dream, who boast a strong 28-14 record, are looking to cement their dominance against a Liberty squad that's been formidable at 26-16.
According to our GameSim prediction, the Liberty hold a slight edge with a 54% win probability, projected to narrowly win 87.1 to 84.1. This game is expected to be a nail-biter, with the Vegas spread at just 1.0 and an over/under of 178.5.
On the court, Breanna Stewart is the Liberty's beacon of hope, projected to score 17.2 points while grabbing 8.2 rebounds. Her teammate Sabrina Ionescu is expected to also shine, contributing 14.8 points and 5.5 assists. On the other side, Atlanta's Allisha Gray and Angel Reese will be crucial, with Reese predicted to dominate the boards, pulling in 15.3 rebounds.
In the other marquee matchup, the Dallas Wings head to the desert to take on the Phoenix Mercury. Despite the Wings' impressive 26-16 record, they cannot afford to underestimate the Mercury, even at 15-27.
Our projections give the Wings a modest edge with a 53% chance to win, forecasting an 85.9 to 83.3 victory. The Vegas oddsmakers appear more confident, setting the spread at 5.0 in favor of Dallas, with an over/under of 172.5.
The Wings' Paige Bueckers is anticipated to light up the scoreboard with 22.5 points, while Jessica Shepard is expected to be a force in the paint with 14.1 rebounds. For the Mercury, Kahleah Copper could be the game-changer, projected to score 24.7 points, and Alyssa Thomas is likely to flirt with a triple-double, contributing across the board.
These matchups encapsulate everything we love about the WNBA: fierce competition, elite athleticism, and the unpredictability that keeps fans guessing.
