Five set pieces showed how close the Union are to breaking through in an important facet of the game. The plays came in succession after the 25-minute mark of a 1-0 win over the Seattle Sounders on Wednesday at PPL Park.

Three corner kicks didn't find Union players in the box and were, albeit shakily, cleared by Seattle. Then two throw-ins, which served as makeshift corners because of defender Sheanon Williams' ability to muscle the ball into the middle of the field, got the Union inches away from scoring.

The first saw Maurice Edu score a goal, only to have it called back because of a Union penalty. The second led to an Edu penalty kick that was saved by Seattle goalie Stefan Frei.

The missed opportunities didn't hurt the Union against the Sounders, but they could keep the club from back-to-back wins when Montreal (5-6-2) visits PPL Park on Saturday night.

The Union (5-10-3) sit one spot ahead of the Impact in the Eastern Conference standings, although Montreal has played five fewer matches.

"It's something we work on a lot in training. Has the execution been there in games? No, it hasn't been," Union head coach Jim Curtin said Tuesday. "We've improved defending them a little bit.

"But we need to really do better executing offensively on set pieces because you see that a lot of these games are decided by set-piece goals, one or two plays here and there in the box."

The Union could not capitalize on early set pieces against the Los Angeles Galaxy on Saturday, and the result was a 5-1 loss. Curtin's team did not score until it was down three goals.

Putting the right service and a well-timed run together will be a major focus of the Union heading into the Montreal game, and for the rest of the season.

"I think we are close in that area," Williams said after practice Thursday. "We're just looking to create havoc in the box and need to do a little bit better to score."
