share-square-3140953 When Lance McCullers Jr. was placed on the injured list with shoulder soreness on May 26, the Astros hoped he’d only miss one start. General manager James Click had described it as “erring on the side of caution.” McCullers still hasn’t returned, which means the Astros will soon go through a fourth turn of the rotation without him. But the 27-year-old wants people to know that he has “zero” concerns about the injury, and he intends to be back quite soon. “Wasn’t anything very serious. We just had to wait for the inflammation to clear,” said McCullers, who inked a five-year, $85 million extension this spring. “Just needed a couple of days and we started building up from there.”
