The Pirates are still evaluating the injury to Diaz (elbow) but believe it may not be too serious. "We're not overly concerned with that compartment at this time," trainer Todd Tomczyk told the Pittsburgh Post-Gazette.
"This is more of a chronic thing," Tomczyk said. "We are in a pause and a holding pattern from games played." Diaz is refraining from using his right arm to throw the ball but is still participating in non-throwing drills.
