When Lazaro Armenteros — or "Lazarito", as he's known in baseball circles — signed with the Oakland A's last year, we knew he'd be heard from again soon. The 17-year-old Cuban prospect has yet to appear in an official minor league baseball game, but he made an appearance in Oakland's split-squad spring training game against the Los Angeles Dodgers on Saturday. In doing so, Susan Slusser of the San Francisco Chronicle notes he became the youngest player in franchise history to play in a Cactus League game.
