The Giants have added another top Dominican pitcher, agreeing to terms with lefthander Adalberto Mejia for $350,000.

Mejia, a 17-year-old from Bonao, has a projectable 6-foot-3, 190-pound body, a loose arm and sits at 87-90 mph, touching 92. Mejia's best secondary offering is his changeup, showing advanced feel for the pitch. He also mixes in a slurvy breaking ball that he'll need to sharpen.

The Giants laid low internationally in 2010, but Mejia is already the second high-profile pitcher the club has signed out of Latin America this year. San Francisco also agreed to terms with Dominican righthander Simon Mercedes for $400,000 after his performance in the Dominican Prospect League all-star game.
