Clay Buchholz received positive news about the health of his shoulder when he visited Dr. James Andrews on Monday. But just how positive depends on who is interpreting the report. Buchholz indicated on Tuesday that he doesn’t expect to be ready to pitch in a major league game until late August or early September. “I definitely have a strain in there,” Buchholz said. “The strength of my shoulder was as good as it’s ever been. It’s all in the throwing motion.” Buchholz said the injury — a strained bursa sac — should heal fairly soon and that his shoulder is structurally sound. Andrews, in fact, told Buchholz that his shoulder was better than he might have expected for a 28-year-old major league pitcher.
