The Mariners have signed three high-profile international free agents, the most prominent being Dominican outfielder Phillips Castillo, who signed for $2.2 million.

Seattle also signed Colombian righthander Jose Torres for $851,000 and Venezuelan third baseman Yordyn Calderon for a $477,500 bonus.

Castillo, 16, is a 6-foot-2, 175-pound corner outfielder and one of the elite hitters on the market with his ability to hit and hit for power. Torres, 16, has a lanky 6-foot-3 frame and is considered the top pitching prospect this year out of Colombia. Calderon, a 16-year-old from Bobures with a projectable 6-foot-2 frame, is a good athlete who can hit for power.
