If Jason Grilli had his way, he would be on the mound for the Pirates as opposed to pitching another simulated game such as the one he threw Tuesday. If all goes well Wednesday, Grilli shouldn't have to wait much longer. The Pirates closer will pitch one more simulated game — to test himself on back-to-back days — and said the next step should include being activated from the disabled list, where he has been since late April. “I'm fulfilling their requirements, and I'm passing with flying colors,” Grilli said. “We as players know when we're ready, and in our minds, we're always ready. We're the horses. They're the jockeys, and we just try to communicate. And seeing is believing, too. But it all feels good, and that's the big thing.” Grilli went on the disabled list April 26, retroactive to April 21, with an oblique strain. He has pitched eight innings in eight games this season and is 0-1 with a 4.50 ERA.
