In preparation for Monday's MLS Waiver Draft, the Union emitted a subtle, "My bad," when they cut ties with three players.

On their way out the door are D Porfirio Lopez, MF Gabriel Gomez and FW Krystian Witkowski.

Lopez, a 27-year-old Costa Rican, was brought in by ex-Union boss Peter Nowak as a sure-fire back with as good a left foot as any. It turned out his left foot was non-existent. He started the first four matches of the season, subbed on for 12 minutes May 19 and never saw the pitch again.

Gomez, a 28-year-old Panamanian, did his part with six goals in 24 matches, including 18 starts. But the Union routinely played him out of his natural position. He was brought on board to be an attacking midfielder who, instead, found himself in the central midfield more often than not. Sure, he had a heck of a free-kick delivery from inside 25 yards, but he was otherwise a bust.

Witkowski, a 22-year-old rookie out of Marist, never really got his shot. He picked up a concussion in reserve-league duty and the 26th pick in the supplemental draft never saw action with the first team.

In terms of a re-do, the Union are looking toward 2013. These three releases are the first in a series of what should be a roster roller coaster this offseason.

In other news, the Union added three names to their traveling cavalcade this offseason.

FW Freddy Adu left Monday for a two-week training stint with Galatasaray, a club in Turkey's Premier League. MF Michael Farfan and D/MF Amobi Okugo will train for an undisclosed stretch with SC Freiberg, of Germany's Bundesliga.

Also on the road this offseason are:

• GK Zac MacMath, who spent time with English Premier League side Everton
• FW Cristhian Hernandez, who was with Real Sociedad, of Spain's La Liga
• MF Jimmy McLaughlin, who is currently training with TSG 1899 Hoffenheim, of Bundesliga
