The Philadelphia Union made MLS history on Wednesday, Matchday 27 on the MLS slate, when 14-year-old Cavan Sullivan took the field as a substitute. At 14 years and 293 days old, he was the youngest player ever to make a regular-season debut for the major North American pro sports leagues. He broke the record that Freddy Adu had set back in 2004 when he appeared for DC United at the age of 14 years, 306 days.
