[U.S. OPEN CUP] The defending champion Seattle Sounders needed penalty kicks to oust their former and future rival Portland Timbers before a sellout crowd of 15,422 in the third round of the U.S. Open Cup on Wednesday night in Portland.

Seattle prevailed 4-3 on penalty kicks against its neighbor from the D-2 Pro League after the game ended 1-1 to advance to the quarterfinals against the Los Angeles Galaxy next Wednesday at Starfire Sports Complex in Tukwila, Wash.

Seattle got an early goal from Nate Jaqua, but Bright Dike equalized for the Timbers late in the first half.

The penalties in front of the Timbers Army played out as such: Kasey Keller stopped Portland's Ryan Pore and Ross Smith for the two key saves in the shootout.

Jaime Moreno and Santino Quaranta scored second-half goals to give D.C. United a 2-0 win over the USL-2 Richmond Kickers.

Six MLS teams and Harrisburg and Charleston of USL-2 reached the final eight.
