Nick Sakiewicz (born January 14, 1961) is a former soccer goalkeeper and current soccer executive. He is currently the CEO and Operating Partner of Keystone Sports & Entertainment, LLC, the ownership group of the Philadelphia Union. He played in the Major Indoor Soccer League and American Professional Soccer League and coached at the youth and college levels. He was the president of both the Tampa Bay Mutiny and the MetroStars.
Sakiewicz, the son of a Ukrainian immigrant father and a Polish immigrant mother, attended the University of New Haven where he played on the school's NCAA Division II soccer team from 1979 to 1982. He was a 1981, 1982 and 1983 All New England and 1982 Division II Second Team All American goalkeeper. After graduating from New Haven, he moved to Europe where he joined FC Nantes as a developmental player, although they have no record of him actually playing there. He also spent a short time with Belenenses of Portugal in 1984. He returned to the United States and played two games for the New York Arrows of the Major Indoor Soccer League during the 1983-1984 season. He spent an extended hiatus from the professional game after a serious leg injury and pursued business opportunities, continuing with the game by coaching and playing at the amateur level. In 1990, he returned to the professional game for one season with the Tampa Bay Rowdies of the American Professional Soccer League.
Following his retirement as a player, Sakiewicz coached youth soccer in Florida and was an assistant coach with the College of Boca Raton.
In the late 1980s, Sakiewicz was a co-owner of the South Florida based Ezell-Titterton Inc. In 1995 and early 1996, Sakiewicz worked as an executive at Major League Soccer. In October 1996, he became the President of the Tampa Bay Mutiny. In 1999 he was named MLS Executive of the Year after three seasons with the Mutiny, before leaving to become President of the MetroStars. With the MetroStars he was named MLS Executive of the Year for a second time in 2000, after the team finished atop the Eastern Division in the regular season. Over five seasons the MetroStars appeared in the 2003 U.S. Open Cup final and qualified for the MLS playoffs four times, but only won one playoff series. The team improved their sponsorship revenue and local broadcasting contracts under his management, but Sakiewicz was openly disliked by local fans due to his failure to appeal to "hardcore" soccer fans and his unfulfilled promises on the construction of the club's own soccer-specific stadium.
During the 2005 season, Sakiewicz was promoted to President of AEG New York, LLC, where he oversaw the sale of the MetroStars to Red Bull in 2006. In November 2007 he left AEG to become the CEO of the ownership group of Philadelphia Union. In February 2008, Philadelphia was announced as the 16th MLS franchise. The Union broke ground on PPL Park in December 2008, and played their first MLS season in 2010.
