Experiencing unexplained shoulder tendinitis, Nick Tropeano was scratched from his Saturday start at PNC Park and placed on the 15-day disabled list.
The Angels moved up right-hander Jhoulys Chacin to take Tropeano’s starting spot and called up right-handed reliever Deolis Guerra from triple-A Salt Lake to take his roster spot.
Tropeano used several terms to describe what he is feeling — “irregularities,” “a little discomfort,” “more stiffness than anything” and “nothing really serious.” He also acknowledged the source of those feelings was undiagnosed, and speculated it could be tendinitis.
“We don’t know what it is,” the 25-year-old right-hander said.
