The Diamondbacks have signed Ismael Pena, a corner outfielder from the Dominican Republic.

Pena, 16, was born in Canada but moved to the Dominican Republic within the last few years. He's a 6-foot-3, 175-pound lefty with a sound swing, a good approach and a hit-first, power-second profile. He's an average runner with a 45 to 50 arm on the 20-80 scale.

Arizona has shown an increased presence internationally during the 2012-13 international signing period, which began on July 2. The Diamondbacks also signed 16-year-old Dominican shortstop Sergio Alcantara (the No. 18 international prospect), Colombian catcher Osvaldo Garcia and Dominican shortstop Fernery Ozuna.
