Mariners Sign Dominican Pitcher Carlos Herrera

The Mariners have signed Carlos Herrera, a 16-year-old righthander from the Dominican Republic. Herrera pitched at Major League Baseball’s international showcase in January in San Pedro de Macoris, where he struck out two with one walk and no hits allowed over two innings, allowing one (unearned) run. He has a long, lanky, projectable frame at 6-foot-3, 170 pounds. Once he gets stronger, that should allow him to add to his fastball, which tops out at 90 mph, and he shows ability to spin a 72-74 mph curveball. Herrera’s trainer is known as “Rumy.”
