San Diego played 54 minutes with 10 men, allowed only two shots on goal and matched Kansas City with 12 attempts. The scoreboard kept the part that mattered. Mariano Beunza scored in the 74th minute, and the No. 16 Roos held off a late USD push to beat the No. 10 Toreros 1-0 on Sunday.
A red card in the 36th changed the assignment. USD could no longer press and cover with the same numbers, yet it reached halftime scoreless and kept the overall shot count level. That balance required the Toreros to choose their forward runs carefully while protecting the space a missing player would normally occupy.
Kansas City found the opening through Beunza, whose 74th-minute goal was his fourth of the season. It was one of only two Roos attempts that reached goalkeeper Austin Adams. Adams made one save; the other shot became the margin. Efficiency, not sustained shooting pressure, separated the ranked teams.
USD responded instead of fading. The Toreros produced nine of their 12 shots after halftime and put three attempts on target during the final 10 minutes. Kansas City goalkeeper Henrik Salcedo stopped chances in the 81st and 88th minutes, then denied another in the 89th. Each save narrowed the remaining options until the final whistle arrived.
Salcedo finished with four saves. USD's Mathias Polz took three shots, while the Toreros' Salcedo put all three of his attempts on target. Seventeen USD players appeared, a rotation that spread the running load after the dismissal but still had to preserve enough attacking personnel for the closing chase.
The personnel count also shows how USD tried to solve the shortage without abandoning the result. Fresh legs could cover ground and keep a forward option available, but every change had to preserve the defensive spacing that held Kansas City to two accurate attempts. By the closing minutes, the Toreros had managed both demands well enough to send three shots at the goalkeeper. None crossed the line.
The equal 12-12 shot total can mislead if read without sequence. Kansas City played with the extra man for more than half the match, but USD generated the denser late pressure. The Roos, however, held the lead during that pressure and could defend the penalty area rather than take the same risks required of a team seeking an equalizer.
The loss moved San Diego to 5-2-1 and Kansas City to 5-1-2. It did not count in the West Coast Conference standings. That distinction gives the Toreros room to separate a difficult road result from the league race, while the red card and late chances provide more useful review material than the rankings attached to each name.
USD opens WCC play at home against Denver on Sept. 26. Sunday's response is worth carrying forward: the Toreros stayed organized enough to concede only two shots on target and created three late saves while short-handed. The correction is equally plain. One lapse produced the only goal, and even a strong 10-man finish could not buy it back.
