One has a heartwarming story and a bat that can’t be ignored. Another is an athletic switch-hitter. The final part of the troika has power, an above average throwing arm, sterling defensive abilities and was considered the second-best player in Dominican Winter League. Combined they cost the Yankees $450,000 to sign. Welcome to the group of outfielders who may or may not be competing for a fifth spot in the wake of Curtis Granderson’s fractured forearm. The story comes from Ronnier Mustelier, a 28-year-old Cuban refugee who hasn’t seen his son, Ronnier, Jr., since the five-year-old was one. Zoilo Almonte is the switch-hitter who has steadily climbed the organization ladder. Melky Mesa, who withdrew from the Dominican Republic’s World Baseball Classic team, is the third entry, and now that he has learned to cut down on strikeouts has put himself in position to be called the favorite.
