Inflammation caused De La Rosa to be scratched from game appearances the past two days, but plans call for him to have a bullpen session Thursday. Apparently he has had occasional issues with the shoulder in the past that have been minor.
The 22-year-old power pitcher was last year's organization pitcher of the year, splitting time between Class A Great Lakes and Double-A Chattanooga. His composite four-year ERA is 2.90 with a .225 opponents' batting average.
This spring, he has made two appearances and allowed two runs in four innings with one home run, three strikeouts and no walks.
