    Like his father, Sierra passes scouts' eye test, standing 6-foot-2 and 175 pounds with room to fill out. As that happens, Sierra will likely have to move from center field to right field. He certainly has the arm strength for right--his throws from the outfield have been clocked at 92 mph. His other tools are impressive as well. He runs a 6.4-second 60-yard dash and can put on a show during batting practice. It's a different story, however, against live pitching. As a lefthanded hitter, Sierra has a tendency to bail out--his step is toward first base--causing him to become exposed against pitches away. Despite his natural tools, Sierra sometimes looks like he's just going through the motions. Still, teams that value tools and projection are dreaming on Sierra, and he's seen as a player who will greatly benefit from getting into pro ball, getting better instruction and playing every day.
