De La Rosa (elbow) threw a successful live batting practice session Tuesday, Nick Piecoro of The Arizona Republic reports.
Manager Torey Lovullo stated that De La Rosa "threw the ball very, very well" Monday. It appears that the 28-year-old's alternative elbow treatment is going well and that he could be available to pitch a minor-league game sooner than later. More updates should hopefully become available in the coming days.
