Marshall has been limited to flat ground throwing after having a setback last week with his shoulder tendinitis. He could resume throwing off a mound on Friday, but that's not certain. "We're real happy with how he's rebounded after a few days off," Price said. "After re-initiating his throwing program, he hasn't had any setbacks, and he feels really good. He's definitely behind schedule, but if we don't have any setbacks and we're optimistic, he'll be ready at least within that first week or two of the regular season."
