Mariners Sign Venezuelan Righthander Ulises Perez

The Mariners have signed 16-year-old Venezuelan righthander Ulises Perez for $190,000.

Perez, who is a slender 6 feet 2, 170 pounds, has touched 90 mph with his fastball and should throw harder in the future because of his arm speed, projectable body, clean arm action and delivery. Perez also throws a curveball and an occasional changeup. Perez became eligible to sign when he turned on July 14, so he’s one of the youngest signings from this year’s class.

Perez also has experience representing Venezuela at the 15U World Championship last August in Mexico. Perez pitched well at the tournament, where in two appearances (including one start) he threw 5 2/3 scoreless innings, allowing two hits and two walks with seven strikeouts. Perez was represented by Felix Olivo.

The Mariners, who entered the 2013-14 signing period with the No. 11 bonus pool ($2.58 million) in baseball, have also signed Venezuelan outfielder-turned-shortstop Greifer Andrade (the No. 21 international prospect), Venezuelan shortstop Luis Rengifo, Dominican catcher Onil Pena and Dominican outfielder Ronald Rosario.
