January 28th, 2022

SEATTLE -- The Mariners on Thursday announced that they’ve signed eight players via the international market, expanding on what’s been a busy offseason in that realm.

In addition to the three that they signed on Jan. 18, when the international signing period opened, Mariners director of international amateur scouting Frankie Thon Jr. announced that the club brought on another group from the Latin American circuits.

Below is a breakdown of each, courtesy of Thon and a release from the Mariners:

• Sebastian Barrios, RHP, Guatemala, 18: He has a wiry, 6-foot-1 frame and has been a multi-sport athlete in his youth. He possesses a loose arm with an athletic delivery. Barrios’ velocity is currently in the high 80s with above-average control.

• William Calderon, RHP, Panama, 17: He has an up-tempo delivery with plenty of deception and possesses excellent athleticism. His velocity is currently in the high 80s and he flashes a tight, above-average slider in his pitching arsenal.

• Joaan De Jesus, INF/C, Dominican Republic, 17: The 5-foot-10 backstop has a strong frame. He possesses defensive versatility and an above-average throwing arm. De Jesus has shown raw power, excellent bat speed and a plus baseball IQ.

• Carlos Gonzalez, C, Panama, 18: He has shown solid tools defensively behind the plate. He is 6 feet tall and showed above-average raw power. He has been praised for his toughness. Gonzalez excelled at national tournaments in his home country of Panama.

• Federik Jimenez, RHP, Dominican Republic, 17: At 6-foot-1, he sports a long and wiry-strong frame, with a high-arm slot delivery. He projects as a power reliever, pairing a fastball that currently sits in the low 90s with a developing curveball that has already shown flashes of being a solid pitch.

• Erick Rodriguez, RHP, Venezuela, 18: He has a physical 6-foot-1 frame but is surprisingly agile due to his athleticism. His fastball velocity currently sits in high 80s to low 90s, with hitters struggling to hit the pitch in the air. He has also shown potential for a solid curveball.

• Wuilliams Rodriguez, RHP, Venezuela, 17: He has a long-limbed, 6-foot-3 frame with a projectable build that contributes to a smooth delivery. He already has a solid feel for his three-pitch mix. With a fastball in the high 80s, paired with above-average control, he has the makings of a potential starter.

• Dervy Ventura, UTIL, Dominican Republic, 18: He is athletic and versatile in the field, with the ability to play both middle-infield positions, as well as center field. At the plate, the 5-foot-8 utility man is a switch-hitter with a contact-oriented approach that is complemented by his plus speed.

"We are excited to add this crop of young talent to our organization,” Thon said in a statement. “We are extremely proud of everyone involved in the process of evaluating and signing these young men. It’s a memorable day for these 8 players, as well as their families. We look forward to the start of their pro careers with the Mariners.”

The three players that the Mariners signed last week are outfielder Lazaro Montes (No. 8 on’s Top 50 International Prospects list), shortstop Michael Arroyo (No. 41) and No. 48 Martin Gonzalez, a shortstop from the Dominican Republic.

Terms of the deals were not disclosed. The Mariners entered the offseason with a base signing pool for international free agents of $5,179,700.
