The Rangers have officially signed Dominican outfielder Nomar Mazara according to Anthony Andro of The Star-Telegram (on Twitter). Enrique Rojas of ESPNDeportes.com originally reported the agreement. The deal would top the previous watermark set by Athletics pitcher Michael Ynoa, who signed for $4.25MM in 2008.
Mazara, 16, stands at 6-foot-5 and hits for power from the left side. Rojas writes that he is considered to be the best power-hitting prospect out of Latin America since Wily Mo Pena and Miguel Cabrera. The Blue Jays, Red Sox, and Athletics also showed interest in the 16-year-old, the source said. Ben Badler of Baseball America (via Twitter) previously said that it was difficult to gauge what kind of bonus the outfielder might command.
