Cavan Sullivan broke Freddy Adu's longstanding record as the youngest player to feature for a senior MLS side when he took the field for the Philadelphia Union in their match against the New England Revolution on Wednesday.
Sullivan, who is 14 years 293 days old and was called into the senior squad for the first time on Tuesday, came on late in the second half to break the record held by Adu.
The young American phenom signed the largest homegrown contract in Major League Soccer history on May 9, in a deal that stipulates Sullivan will transfer to English Premier League power Manchester City after he turns 18.
