However, they stumbled in their most recent match, suffering a 4-1 loss to Colorado.   That result came after Gabriel Pec received a red card, forcing the Galaxy to play much of the match with ten men. They’ll look to bounce back and secure their second win of the MLS season in this home fixture.   Sporting Kansas City, meanwhile, are enduring a difficult start under new head coach Raphael Wicky. The club has recorded two losses and one draw in its opening three matches.   Even more concerning, Kansas City hasn’t won an MLS match since August 2025. With just one point from nine available, SKC currently sits at the bottom of the Western Conference standings and will be desperate to end its winless streak in Los Angeles.   The LA Galaxy vs. Sporting Kansas City match kicks off Saturday at 6:30 PM PT.     Comparing Other Sportsbook Offers for MLS Betting   While BetMGM offers a competitive promotion, several other sportsbooks also provide welcome bonuses for MLS bettors.   Caesars Sportsbook New users can claim a 100% first-bet match up to $250 in bonus bets.   Fanatics Sportsbook Fanatics offers a 10-day streak promotion, allowing bettors to earn up to $1,000 in FanCash rewards on daily wagers.   FanDuel Sportsbook New customers can take advantage of the “Bet $5, Get $250” offer when their first bet wins.
