The Las Vegas Aces entered Sunday looking for another early-season win. Becky Hammon walked away with a milestone that further cemented her place among the WNBA's coaching elite. Las Vegas defeated the Golden State Valkyries 91-81 on Sunday, giving Hammon the 150th victory of her WNBA coaching career. Even more impressive, she reached the mark in just 205 games, making her the second-fastest coach in league history to do so.For a coach who didn't take over the Aces until 2022, the accomplishment is another reminder of just how dominant Las Vegas has been during her tenure. Hammon has transformed the franchise into one of the defining dynasties of the modern WNBA. Since arriving in Las Vegas, she has guided the Aces to three championships in four seasons while compiling one of the league's best winning percentages. Sunday's victory added another chapter to that resume..Becky Hammon's impact goes beyond the win columnWhile 150 victories is a significant number, Hammon made it clear after the game that the process behind those wins matters more to her than the total itself. According to ESPN, Hammon pointed to last season as an example of why she remains focused on development rather than results. The Aces endured a rocky first half of 2025 and were hovering around .500 at the All-Star break before turning things around and eventually capturing another championship.That approach has helped establish a culture that players consistently praise. Aces superstar A'ja Wilson delivered perhaps the strongest endorsement of her coach after Sunday's win, saying Hammon gives players confidence and trust even during difficult moments. Wilson added that Hammon's ability to support her players is one of the reasons the team remains so connected year after year.For a franchise that has already won multiple championships together, that bond may be one of the biggest reasons Las Vegas continues to contend.MORE: Stephanie White sends clear message about Indiana Fever veteran's roleAces continue building momentumThe game itself was another encouraging step for Las Vegas. After leading by only two points at halftime, the Aces took control with a dominant third quarter, opening the second half on a 21-6 run. Golden State eventually trimmed the deficit to single digits late, but the outcome was never seriously threatened.The 91 points were the most the Valkyries have allowed this season, another sign that the Aces' offense is beginning to find its rhythm. Hammon, however, wasn't interested in declaring the finished product has arrived.She acknowledged after the game that every season requires a team to establish a new identity, regardless of what happened the year before. That mindset may explain why Las Vegas continues to avoid complacency despite all of its recent success.The rest of the WNBA already knows what Hammon has built in Las Vegas. Sunday's milestone simply provided another number to back it up. With 150 wins now secured and another championship chase underway, the Aces' coach continues adding to a resume that already ranks among the best in league history.More WNBA NewsIndiana Fever veterans are already embracing rookie in viral Sophie Cunningham interactionWNBA expansion teams are proving they belong much faster than expectedIndiana Fever’s high-powered offense is becoming one of the WNBA’s biggest early storylinesKelsey Plum injury leaves Sparks facing major early-season testAngel Reese keeps proving Atlanta Dream made the right bet
