(D.C. United) (D.C. United)

Greetings from Manaus Kansas City.

Brutal heat has enveloped the region, with the temperature peaking at 100 and humidity near 50 percent this afternoon on the Kansas side of the Missouri River.

At least the D.C. United-Sporting KC match is in the evening, unlike the NWSL semifinal between FC Kansas City and the Portland Thorns on artificial turf at UMKC this afternoon. During the scheduled hydration breaks, players dipped their cleats in buckets of water.

Tonight at Sporting Park, United has an opportunity to overtake Kansas City for first place in the Eastern Conference and, for at least a few hours, move atop the Supporters’ Shield table.

Fact: SKC and DCU boast the lowest goals against averages in MLS.
