Philadelphia’s Cavan Sullivan, 14, breaks Freddy Adu’s youngest MLS player mark

• Sullivan, 14, is considered future USMNT star
• Expected to join City at 18 in pre-arranged transfer

Cavan Sullivan became the youngest player to appear in an MLS match, Tai Baribo had his first career hat trick and Kai Wagner added three assists to help the Philadelphia Union end a 10-match winless streak with a 5-1 romp over the New England Revolution on Wednesday night.

Sullivan - at 14 years, 293 days - replaced Baribo in the 85th minute, topping the record by 13 days. Freddy Adu set the previous mark at 14-306 when he debuted for DC United in 2004.
