LA Galaxy oust Sounders to set U.S. Open Cup semifinals

The LA Galaxy will meet FC Dallas and the New England Revolution will face the Chicago Fire in the U.S. Open Cup semifinals Aug. 9-10.

The LA Galaxy are one game away from advancing to their first U.S. Open Cup final in 10 years.

The Galaxy notched a 4-2 win over the Seattle Sounders in Carson, California, on Wednesday, booking their place in the Open Cup semifinals alongside FC Dallas, the New England Revolution and the Chicago Fire.

Sebastian Lletget scored twice for the Galaxy in the final five minutes to secure the quarterfinal triumph, with Alan Gordon and Giovani dos Santos also netting for the hosts. Michael Farfan and Herculez Gomez scored for a Seattle team that had won four Open Cup titles and lost a final since entering MLS in 2009.

The Galaxy, on the other hand, have won a pair of Open Cup crowns but have not appeared in the final since falling to Chicago in 2006.

They will host FC Dallas on Aug. 10 after Oscar Pareja's side earned a dramatic 1-0 victory at the rival Houston Dynamo.

With extra time looming, Fabian Castillo scored a stunning 91st-minute strike to send Dallas into the semifinals.

Elsewhere, the Philadelphia Union — who have hosted and lost the past two Open Cup finals — were eliminated on penalty kicks after playing to a 1-1 draw at New England.

Je-Vaughn Watson was the hero for the Revolution, scoring in regulation before converting the clinching penalty kick. Brad Knighton made two stops as New England won the shootout 4-2, meaning Fabian Herbers' 90th-minute equalizer for Philadelphia went to waste.

New England will visit Chicago in the other semifinal Aug. 9 after the Fire cruised to a 3-0 win over the NASL's Fort Lauderdale Strikers, the last lower-level club remaining in the competition.

David Accam, Michael de Leeuw and Khaly Thiam scored for Chicago.
