Buzz off the Court
Both teams have numbers that speak for themselves and they both also have an MVP Candidate on their hands. Wilson and Stewart are leading the way in this category. With the award getting announced on September 7, this could happen during the middle of the series.
Games one and two are in Vegas on August 29 and August 31. The teams travel to Seattle to play on September 4. Vegas took the regular season series lead 3-1 and it would come as a surprise to no one if the series went four or five. Game four would be on September 6 and the final game on September 7.
This is Sue Bird’s final season and the Storm are running for another championship earning their fifth title. Bird already has a lengthy resume currently in seventh place overall in points with 6803. She is currently the overall leader in games played (580) and the league’s assist leader with 3234.
There are seven number-one overall draft picks during this matchup. Vegas has three with Plum (2017), Wilson (2018), and Jackie Young (2019). Seattle has the other four with Bird (2002), Tina Charles (2010), Jewell Loyd (2015), and Stewart (2016).
This is the first season under Aces head coach Becky Hammon and she is looking to get her team to her first finals series. They have fallen short in the last few years even falling to Seattle 0-3 during the 2020 WNBA Finals.
The Aces are playing with a chip on their shoulder while the Storm is trying to finish strong for their point guard Sue Bird. This series is going to be a battle and we think the series will end with a 3-2 Aces victory.
WNBA Semifinals Betting Odds
Currently, the Aces are -250 favorites to defeat the Storm, according to the WNBA Semifinals betting odds, and move on to the WNBA Finals with Seattle at +210. If you convert those odds into implied probability, Vegas is 71.4% likely to advance, with Seattle at just 32%.
The Aces are a great team and look to be rolling, but the same can be said for Seattle. There were certain pundits out there that theorized that the winner of the Seattle Storm vs Washington Mystics would go on to the WNBA Finals, knowing it would likely be Vegas waiting for them in the semifinals.
That being said, the right team is certainly favored here, but there’s value on Seattle at this number for the WNBA Semifinals series odds. If you want to take Vegas, that’s fine, there’s just not a lot of value. If you want to grab Seattle, do so at the current number.
If you want to grab Las Vegas, it could be beneficial to wait until after the first game of the series. If the Aces fell to the storm in the first game, it would lower their odds. They would likely still be the favorite to win the series but at a much more consumer-friendly number.
