Magneuris Sierra is more highly regarded than is Lee. His tools are more evident and he has a higher apparent ceiling. His arrival to the Miami Marlins is delayed by a tight hamstring, but we should see him sometime in the first two months of this season.
Sierra is a 5’11”, 160 lb. outfielder from San Cristobal, Dominican Republic. Now 21-years-old, he slashed .317/.359/.317 in 22 games last year for the Cardinals. The Marlins received him with Sandy Alcantara for Marcell Ozuna on December 14th.
Sierra has stolen exactly 100 bases through his professional career, and been gunned down 46 times. Although he could stand to be more selective, I can’t fault his enthusiasm.
Alcantara has slashed .292/.339/.378 through five minor league seasons. He played 2013 with the DSL Cardinals, graduated to the GCL Cardinals in 2014, played between the Johnson City Cardinals and the Peoria Chiefs in 2015, remained in Peoria in 2016, and spend last season between the Palm Beach Cardinals and the Springfield Cardinals. He has never appeared at the triple-A level.
Even faster than Lee, Sierra fits the mold of the prototypical leadoff outfielder. His prospect “speed ” rating is 70, which is the highest of any Marlins prospect.
