Always among the most active teams internationally, the Mariners today announced the signing of 10 international free agents.

The Mariners confirmed the previously-reported signing of lefthanded outfielder Guillermo Pimentel, an advanced 16-year-old power hitter from the Dominican Republic who signed for $2 million.

"(Pimentel is) a kid with a lefthanded power bat," Mariners international scouting director Bob Engle said in a press release. "He’s extremely strong with a good approach to hitting. He has a crisp, compact stroke and both drives and lofts the ball."

International scouts from outside the organization said that, among the Mariners Latin American signings, the biggest hauls outside of Pimentel were 16-year-old Dominican outfielder Alfredo Morales and 16-year-old Venezuelan third baseman Andres Brito. Morales is a 6-foot-2, 180-pound lefthanded hitter.

"(Morales) has a great approach to hitting," Engle said. "Very good rhythm and uses his hands well. Solid-average arm and a plus runner. A quiet, intense worker." 

The main draw with Brito is his power, and at 6-foot-4, 230 pounds, some scouts think he will end up at first base. The Mariners also signed 16-year-old Alexis Palma, a 6-foot-3, 170-pound righthanded outfielder from Venezuela with a plus arm and projectable power. Pimentel, Morales and Brito all received invitations to the team’s instructional league this fall in Arizona.

The other 16-year-old Latin American signings the Mariners confirmed are:

• Panamanian RHP Waldy Alvarez (6-foot-2, 170 pounds) 

• Venezuelan RHP Julian Alvarado (6-foot-2, 155 pounds)

• Venezuelan RHP Daniel Mata (6-foot-4, 165 pounds)

• Colombian righthanded-hitting infielder Diego Mina (5-foot-10, 170 pounds)

The Mariners were also active in the Pacific Rim, signing Korean catcher Ji-Man Choi and Korean righthander Seon-Gi Kim. Choi, 18, is a 6-foot-1, 183-pound lefthanded hitter from Dongsan High in Inchon, Korea. Engle called Choi "a skilled receiver with a solid arm. He has a power bat and was considered the best lefthanded bat in Korean high school play this year."

Kim, who at 17 is 6-foot-2, 185 pounds, is from Sekwang High in Cheongju City, Korea.

"Our scouts have been following Seon-Gi for the past two seasons," Engle said. "He is lean with a projectable frame with good pitching mechanics and arm speed producing solid-average velocity and the makings of good breaking stuff."
