Get ready for a thrilling WNBA matchup, but don't expect Jackie Young to surpass 19.5 points in the upcoming Aces vs. Sun game. 

The Las Vegas Aces and Connecticut Sun are two of the WNBA's powerhouse teams, and they're preparing for an intense rematch after the Aces took home the 2022 WNBA finals. With the Aces on a four-game road trip and both teams boasting impressive winning streaks, this week's games are a must-watch for basketball fans and bettors alike. 

But amidst the excitement, there's one particular under bet that deserves some attention: Jackie Young's points line at 19.5. Now, don't get me wrong - Young is an undeniably talented player, leading the Aces with an average of 21.8 points per game. However, there are several factors that suggest she might not reach the 20-point mark against the Sun.

Firstly, these two teams are no strangers to each other, having faced off in the 2022 WNBA finals. The Sun know Young's strengths and weaknesses, and they'll be eager to shut her down and prevent a repeat of last season's outcome. Connecticut's defense has been on point this season, with all of their victories coming by single-digit margins. That means they've been able to keep games close and limit the scoring of their opponents, including star players like Young.

Additionally, Aces' forward A'ja Wilson has been the leading scorer in half of the six games this season, averaging 20.7 points per game. The Aces have multiple scoring options, and they might not lean as heavily on Young to put up big numbers. 

On the Sun's side, DeWanna Bonner has been leading the team in scoring, averaging 16.0 points per game. She's made it clear that the Sun are focused on defense, saying, "We know we have a lot of offensive power but if we lock in on defense, I really believe that this team is pretty much unstoppable." This mindset could prove crucial in limiting Young's point production during the upcoming matchup.

Furthermore, the Sun's Alyssa Thomas has become the franchise's all-time leader in free-throw scoring, reaching 692 made foul shots. Connecticut is no stranger to getting to the line, and if they can draw fouls from Young and the Aces, it could limit the amount of time Young spends on the court, it's likely that the Sun will be working hard to contain Young subsequently impacting her scoring potential.

Aces' coach Becky Hammon has acknowledged the importance of defense in this matchup, stating, "We've got to do a better lock-in job on those microwave scorers, those people who demand that kind of attention." Young being a tough defender might focus a lot on defense in this matchup, limiting her scoring subsequentl.

While Jackie Young has had an impressive season so far, it's important to consider the context of this particular matchup. With the Sun's defensive prowess and the Aces' multiple scoring options, it's reasonable to think that Young might not surpass 19.5 points in the upcoming game. As a young, data-driven sports analyst, I encourage bettors to consider this under bet, but remember that nothing is a sure thing in sports. Keep an eye on this exciting matchup and watch as the Aces and Sun continue their battle for WNBA dominance.
