Kimball, a hard-throwing, promising set-up candidate, has been on the disabled list since June 10. He pitched June 9 in San Diego and immediately walked into the trainer’s room to admit he had been pitching with pain since the beginning of the season, and it had become untenable to pitch through.
On June 17, Kimball played catch for the first time since the injury. He continued on a throwing program but hit a setback shortly thereafter, at which point the Nationals shut him down for two weeks. Kimball tried to throw again yesterday, and when he still felt soreness the Nationals sent him for more tests, including a procedure in which dye will be inserted into his ailing shoulder.
