A former Netherlands youth international, the 23-year-old adds depth to New England's forward corps.
The Revolution on Monday announced the signing of former Ajax striker Geoffrey Castillion on a free transfer. The 23-year-old represented the Netherlands at the U-17, U-18 and U-19 levels.
"Geoffrey is a big, strong target forward with several years of experience in the Dutch first division," Revolution general manager Michael Burns said in a news release. "He will add a different dynamic to our attack and also give us more options up front."

A product of Ajax's youth academy, Castillion saw his only first-team appearance for the club come in 2011. He split the 2013-14 campaign between Ajax's reserves and a loan stint with Eredivisie side NEC Nijmegen.
He'll compete for minutes up top in Revolution coach Jay Heaps' 4-1-4-1 formation with Charlie Davies, Patrick Mullins and Dimitry Imbongo. At 9-12-3, New England is one point out of the final Eastern Conference playoff slot.
