MLS Supplemental Draft. Wolyniec came into his own during his second stint with the team, scoring a number of key goals, including two overtime game-winners and a late winner in the U.S. Open Cup semifinals against D.C. United. He finished the year with five MLS goals (seven in all competitions). On May 26, 2004 Wolyniec scored two goals and assisted on another in a 3-1 victory over Boavista F.C. of the Portuguese Liga. Even as the team signed a trio of foreign strikers in 2004, he kept his starting place, scored ten goals to tie for the team lead, and began to mature into a team leader. But after scoring two goals in eight games in 2005, he was traded to the Columbus Crew in exchange for prolific scorer Ante Razov. After scoring three goals for the Crew, Wolyniec was dealt in May 2006 to Los Angeles Galaxy in a four-player deal. In August, he was traded again, joining New York Red Bulls for his third stint with the club formerly known as MetroStars. The 2007 and 2008 seasons saw Wolyniec primarily as a reserve player for New York, managing to score 3 goals in 21 appearances in 2007 and being held scoreless in 19 regular season appearances in 2008. With the Red Bulls barely qualifying for the 2008 MLS Playoffs, Coach Juan Carlos Osorio surprisingly inserted Wolyniec into the starting lineup for the club's first leg match against the defending champion Houston Dynamo, Wolyniec would assist on Juan Pablo Angel's goal in a match that ended 1-1. With New York needing a victory to advance out of the first round for the second time in team history, Osorio repeated the same lineup that drew 1-1. Wolyniec was again a key figure scoring the third goal in a 3-0 rout of Houston in Robertson Stadium. Wolyniec continued his fine play in the Western Conference Final, helping set up the Red Bulls' lone goal in the 1-0 victory over Real Salt Lake, and thus advancing to the club's first ever MLS Cup Final. In the MLS Cup Final, Wolyniec scored the Red Bulls lone goal in a 3-1 loss to the Columbus Crew. During the 2009 season Wolyniec was the only New York player to score in all competitions that the club participated in (League, US Open Cup, CONCACAF Champions League). On May 12, 2010 Wolyniec had his first multi-goal game
