He's been living in the U.S. since he was a teenager, if I remember correctly (he went to high school in New York City), so he's definitely comfortable speaking English (unlike someone like Vlad Guerrero, who's still not comfortable speaking publicly in English because he's only really in the U.S. during the season). I saw that press conference, too, and thought he was hilarious, talking about selling the rights to his "soap opera" the past couple years to the local Univision station in LA, and presenting it with no commercials so people could really concentrate on watching it.
