I just got my info from here from the current roster section. It's Wikipedia so obviously not the most credible source, so he very well could be and hopefully is.

Edit: tfc doesn't list him as homegrown on their website, they don't list spencer as homegrown (via real salt lake) either. Also Delgado is a homegrown player (via chivas) but we had to put him on our protected list. Quillan Roberts was also homegrown, but wasn't autoprotected either. As always, MLS rules are questionable
