From Rotoworld:

Quote of the Week, courtesy of San Francisco Chronicle reporter Susan Slusser talking about 17-year-old A's pitching prospect Michael Ynoa: Santiago Casilla told me a few weeks ago when I asked if he'd seen Ynoa this winter that Ynoa has "beautiful eyes," which made me laugh, since I'd been asking about his pitching. (Casilla hadn't seen him pitch, as it turned out.) But Casilla wasn't just cracking a joke: Ynoa does have extraordinary eyes—aquamarine or sea green, something like that. Striking.

Well, now we know where his awesome talent comes from!
