What happened: Díaz made his first start after debuting as a substitute in a 2-1 road win three days earlier. Gregersen entered after playing all 90 minutes in that victory.
Why it matters: The late defensive change put a fresh center back into a one-goal game. Protecting the lead carried added weight with the club six points below the playoff line.
By the numbers: Gregersen recorded six interceptions in his previous appearance, an MLS-best mark for that match.
What to watch: Watch whether Gregersen remains in the rotation after consecutive late-game assignments.
