Phillips Castillo, OF, Arizona League Mariners (Rookie, 20.0 years old on average in 2011)
6-2, 190 lbs, 18 years old
Bats: Right, Throws: Right
Acquired: International Signing (2010)
Since Jack Zduriencik has been the Mariners general manager, the team has put a huge emphasis on international scouting and player acquisition. Several of the players that they’ve added using that process have already appeared on this prospect list. Presently Castillo is the best prospect of the bunch. Considered one of the best hitters of the 2010 class of free agents, Castillo came stateside and produced pretty well in the Arizona League (.848 OPS), Castillo probably didn’t hit as many homeruns as a successful season by him would be expected to produce, but his 24 extra-base hits in 48 games is impressive at any level. Castillo has very few doubts about his defensive ability, which is really what gave him the nod over Guillermo Pimentel. Even though Castillo will likely end up in a corner outfield spot, he’s likely to be a plus-defender there.
Potential (of 40): 40
