Rosario is an outfielder with a good arm, good speed and some power potential, despite his size.  He didn’t hit a great deal in his first one and a half years in the DSL, but the Pirates promoted him to the GCL in late July 2013.  It’s unusual to see mid-season promotions from the Latin American summer leagues, but the Pirates may have felt the GCL team needed an outfielder after Luis Urena was promoted to West Virginia.  He was on the old side for a Dominican prospect when he signed.

DSL:  226/349/378, 164 AB, 6 2B, 5 3B, 3 HR, 29 BB, 44 K, 6-15 SB

Rosario played center more or less regularly, recording ten assists.  He showed some power and drew a lot of walks, but had trouble making contact.

DSL:  200/333/360, 75 AB, 1 2B, 4 3B, 1 HR, 14 BB, 20 K, 3-4 SB
R:  178/260/178, 45 AB, 5 BB, 10 K, 2-3 SB

Rosario’s playing time decreased and he moved primarily to right, with the presence of Michael De La Cruz in center.  He didn’t hit as well and continued to walk and strike out at about the same rate.  The Pirates moved him up to the GCL after some promotions left the team short on outfielders.  He played some in both right and center, and did little offensively other than draw a few walks.

R:  301/383/480, 173 AB, 10 2B, 6 3B, 3 HR, 20 BB, 28 K, 3-8 SB

After doing little his first two years, Rosario suddenly started hitting in 2014.  In fact, he was the GCL team’s best hitter along with Tito Polo.  He was two years older than Polo, though, so it’s hard to say how much his stats mean.  Rosario opened the season as a backup, but thanks in part to Michael De La Cruz’ problems, he ended up playing slightly more in center than De La Cruz.  Rosario hit LHPs almost exactly the same as RHPs.

Rosario will turn 22 at the start of the 2015 season, so if the Pirates consider him a prospect they’ll promote him aggressively.  He could see time at Morgantown or even West Virginia.
