Del Rosario most recently pitched on May 2, in a home start against the visiting Lake County Captains, from Ohio. Cedar Rapids won, 7-3. 4 IP, 5 hits, 3 R, 2 ER, 3 BB, 4 SO Del Rosario escaped an interesting first inning, which began with a base on balls, followed by a caught stealing, a strikeout, a base hit, passed ball, and another hit with the runner being thrown out at the plate. After three apparently quiet innings, Del Rosario got into trouble in the fifth. He left after the first five batters reached base (hit, walk, hit, walk, error).
