Yankees reliever Rafael Soriano will not pitch in the team's two-game series against the Rays, which begins on Monday. Soriano, who signed a $35 million contract this past offseason, is experiencing tightness in his right elbow. "I'm going to throw a bullpen [session on Monday] and see how I feel," Soriano said. "If everything goes fine, I'll be ready on Wednesday." Yankees manager Joe Girardi said that the tightness Soriano feels is different than what he felt last week, when the hurler requested an MRI exam to ease his mind. "He had a little pain before," Girardi said. "Today, he was a little sore; he said he had stiffness. That could have been because he hadn't thrown in five days."
