Jason Grilli (oblique) is expected to be activated from the disabled list if a simulated game on Wednesday goes well. Grilli already threw a sim game Tuesday with no issues, but the Pirates want to make sure he's OK to throw on back-to-back days. It appears he will not need a rehab assignment. "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."
