The Rangers have agreed to sign 21-year-old Cuban center fielder Julio Pablo Martinez for the remaining $2.8 million in their international bonus pool. Martinez, eligible to officially sign today, becomes the No. 60 prospect on the Baseball America Top 100, two spots behind White Sox center fielder Luis Robert and one ahead of Blue Jays center fielder Anthony Alford. Martinez slots in as the No. 3 prospect in the Rangers' farm system, behind outfielders Willie Calhoun (No. 36) and Leody Taveras (No. 51). A lefty who is around 5-foot-10, 180 pounds, Martinez has been a standout prospect in Cuba since he was a teenager, showing a promising blend of athleticism, speed, power and performance at a premium position. During his final season in Cuba, Martinez batted .333/.469/.498 in 264 plate appearances and stole 24 bases in 29 attempts. He walked (52) more than he struck out (30), though that had more to do with the decline in the quality of Cuba's Serie Nacional than his plate discipline.
