After signing three of the top players on the international market in the last two weeks, the Mariners have announced the signings of three more pitchers out of Latin America, adding Luis Pina, Rigoberto Garcia and Erick Gomez.

Pina, who is 6-foot-2, 178 pounds, is a 16-year-old lefthander from Venezuela.

"He is accomplished, poised and already has good feel for pitching," Mariners vice president of international operations Bob Engle said in a release. "He will have to make some adjustments in his delivery as many young pitchers do, but physically (he) has ability to be solid in all areas."

Garcia, 16, is a 6-foot-5, 202-pound righthander from the Dominican Republic who could be the sleeper of the Mariners' signings, according to Engle, who noted that Garcia has some similarities to Mariners 21-year-old Triple-A righthander Michael Pineda when he signed in 2005.

"A tall young man who has strong arm and all the makings to become a true power pitcher," Engle said. "He already shows (a) solid-average fastball now with ability to throw well above-average down the road."

Gomez is a 17-year-old lefty from Venezuela who is 6-foot-1, 165 pounds and shows solid feel for pitching.

Engle also talked about the Mariners' three major international signings, including 16-year-old Dominican outfielder Phillips Castillo, whose $2.2 million signing bonus is a franchise record for an amateur player out of Latin America. 

"We have been following Castillo for two years and believe he was the best position player available among the July 2nd candidates," Engle said. "He is exceptionally strong for his age and another player with a great makeup. The ball explodes off his bat and (he has) good running speed. He has an above-average arm and solid in the field."

Righthander Jose Torres, who signed with the Mariners for $851,000, is 6-foot-4, 165 pounds and considered the top 16-year-old pitching prospect this year out of Colombia.

"A tall, thin young man with very good delivery and very projectable body build," Engle said. "He is a hard worker, very intense and has a good aptitude. Torres has (a) chance to throw harder down the road and displays (an) advanced breaking ball for his age."

The Mariners also signed 16-year-old Yordyn Jose Calderon, a 6-foot-2, 185-pound third baseman out of Venezuela. Calderon was one of the better prospects in Latin America because of his bat but he has shown solid tools in the field as well with good hands and a strong arm.

"We felt he was one of the more accomplished young hitters available in the international market," Engle said. "He has a great makeup and is sound fundamentally at the plate. Calderon drives the ball hard as well as showing some long ball ability."

Castillo, Calderon, Torres and Pina will all report to the Mariners' instructional league in September.
