The momentum shifts have been dramatic in the first two games of the series, and I’m counting on another swing in Game 3 as I put together my Liberty vs. Mercury prediction.

Phoenix is a -140 betting favorite ahead of tipoff at 9 p.m. ET on Friday at PHX Arena (ESPN).

For my WNBA picks, I anticipate a healthier Breanna Stewart for a win-or-go-home matchup, and I’m backing the Over on one of her player props.

The Liberty were embarrassed on home court with a chance to win the series in Game 2. They shot just 30.2% from the field and missed nine of their 25 free-throw attempts. It was a disastrous offensive showing.

Despite that, I’m fairly confident in New York’s ability to quickly move past that rough performance with a chance to set up a WNBA Finals rematch with Minnesota in the next round.

I have a very hard time seeing the star trio of Sabrina Ionescu, Breanna Stewart, and Jonquel Jones combining to make just eight of 28 attempts (28.5%) as they did in Game 2.

I think getting this type of value on a team with as much star power as New York in an arena the Liberty have already conquered in this series is too tempting to pass up. 

A $10 bet on New York to win would provide a profit of $12.40. The +124 odds from one of the best sports betting sites, FanDuel, have an implied probability of 44.64%.


💰 Best Liberty vs. Mercury player prop bet

⬆️ Breanna Stewart Over 13.5 points (-110) ⭐⭐⭐⭐

Breanna Stewart played through a left knee injury in Game 2 to finish with six points on 33.3% shooting in 20 minutes. I think the uncertainty surrounding her knee is playing a big factor in this line.

Stewart scored 18 points in 40 minutes during New York’s Game 1 victory and put in at least 14 points in each of the last five games of the regular season. She averaged 18.3 points per game during the campaign.

Getting a four- or five-point difference from Stewart’s season average feels like a great opportunity. Stewart also scored at least 14 points in three of her four regular-season meetings with Phoenix. 

A $10 wager on Stewart’s Over nets out a profit of $9.09 at Caesars. The -110 odds have an implied probability of 52.38%.

📈 Liberty vs. Mercury betting odds analysis

The Mercury opened as the 1.5-point home favorite, with the line being offered at -2.5 at some of the best sports betting apps. Considering the lopsided score in Game 2, it wouldn’t be that surprising if the line continues to inch a little higher in Phoenix’s favor at home.

How do WNBA odds work?

When betting on the WNBA, the point spread shows how many points the favorite needs to win by in order to cash the bet. For example, a favorite of -5.5 must win by 6 or more points to cover the spread, while an underdog at +5.5 must win outright or lose by 5 or fewer points to cover the spread.

Moneyline odds represent the payout for picking the outright winner (+200 means a $100 bet wins $200, while -200 means a $200 bet wins $100). Over/Unders let you wager on whether the combined total will be higher or lower than the set number.
