Seattle Sounders vs San Diego FC Prediction – MLS May 2026

Seattle Sounders welcome San Diego FC to Lumen Field on May 10, 2026, in a Major League Soccer fixture that strongly favors the home side based on current form and home advantage. The Sounders have been in fine fettle recently. A 4-1 thumping of St. Louis City at Lumen Field was followed by a 2-1 win over FC Dallas — both at home — and a creditable 1-1 draw at Sporting KC. Seattle have scored 7 goals and conceded just 3 in their last three matches, showing a team with attacking punch and a solid defensive foundation. Lumen Field, one of MLS's most electric atmospheres, has traditionally been a fortress for the Sounders, and that should count heavily tonight. San Diego FC travel north in deeply concerning form. Their last four results read: a draw with LAFC (2-2 at home), a home loss to Portland (1-2), a road defeat at Houston (0-1), and a 4-2 shellacking at Real Salt Lake. That's 9 goals conceded in 4 games — an average of 2.25 per match — and just 1 point to show for it. Away from home, the numbers are even grimmer: 5 goals conceded in their last 2 road fixtures. San Diego are not entirely toothless in attack — they've scored in three of their last four games, including netting twice against both LAFC and Real Salt Lake. That dual-edged reality makes both-teams-to-score a credible proposition, but their defensive woes give Seattle's forwards an inviting target. With no lineup information currently available, there is inherent uncertainty around key absences or rotations, particularly in Seattle's attack. No head-to-head data is available to provide historical context, and the absence of bookmaker odds means all probabilities are derived purely from form analysis. Despite those data gaps, the direction of this match seems fairly clear: Seattle should dominate at home, controlling the game through possession and pressing, with San Diego likely to offer sporadic counter-attacking threat. The predicted outcome is a 2-1 Seattle win. The Sounders' home advantage, superior recent form, and San Diego's brittle defense all point in one direction. Over 2.5 goals is slightly below even-money given San Diego's tendency to concede — and score — in bunches. Confidence sits at 62%, reflecting data limitations but a clear enough form gap to lean decisively toward the home side.
