WTM’S PIRATE PLAYER PROFILES

Del Rosario is a lefty with good size.  At the time they signed him, he reportedly could throw up to 93 mph.  Early in training camp in 2013 he was throwing only 83-84, although with a good curve.  He’s had exceptionally low K rates in the DSL.

2011
DSL:  6-2-2, 3.53 ERA, 1.35 WHIP, 51.0 IP, 3.5 BB/9, 3.4 K/9

Splitting his time between starting and closing, Del Rosario pitched effectively but with an extremely low K rate.

2012
DSL:  5-2-0, 2.66 ERA, 1.12 WHIP, 61.0 IP, 1.6 BB/9, 4.1 K/9

Pitching strictly as a starter, Del Rosario improved, mainly in the form of an extremely low walk rate, but he continued to fan very few hitters.

2013
R:  2-3-1, 5.87 ERA, 1.15 WHIP, 38.1 IP, 1.4 BB/9, 7.5 K/9

Del Rosario pitched mainly in relief in the GCL.  He was much more effective than his ERA indicates, although he did allow four HRs.  His K rate was much improved.

Del Rosario opened at Bristol in 2014.
