The 30-year-old made amends for a disappointing first-half penalty by heading home a 79th-minute winner as Ben Olsen's side stunned Philadelphia this morning.
Visiting coach Jim Curtin could have hardly wished for a better start in Union's trip to the capital as they raced into a 2-0 lead inside four minutes.
The hosts slowly but surely developed a foothold and Espindola rifled his effort just wide of the post on 16 minutes, before suffering a worse miss shortly after the half-hour mark.
On 66 minutes, the comeback was complete when Nick DeLeon tapped home a rebound from close range after Sylvestre fumbled Espindola's tepid long-range attempt.
Not content with drawing level, United went in search of a winner and it came 11 minutes from the end as Espindola redeemed himself by heading home Chris Korb's cross to snatch the victory. body check tags ::
