SARASOTA, Fla. -- Orioles right-hander Chris Tillman, who has yet to pitch this spring due to right shoulder soreness, was scheduled for a bullpen session Saturday, but that was pushed back until Sunday, manager Buck Showalter said.
Tillman had a platelet-rich plasma injection on the shoulder in late December, and the Orioles have said he won't be ready to pitch on Opening Day. They hoped he could pitch in the season's first week, and last month set March 17 as a target date.
"He was taking an antibiotic and one of the side effects is some soreness in the joints. They got him off that and changed the antibiotic. They decided to wait an extra day before he throws," Showalter said.
"It doesn't affect his schedule as long as everything goes well tomorrow. They thought it might have been affecting him a little bit, so they're going to change the antibiotic and get him on some that doesn't have those potential side symptoms."
• In other injury news, right-handed pitcher Logan Ondrusek, who is suffering from elbow discomfort, will see orthopedist Dr. James Andrews on March 20. Showalter said that if surgery is required, it could be performed the next day.
• Outfielder Michael Bourn, who has a broken right ring finger, saw a hand specialist on Friday, and is recovering well, Showalter said.
• Chris Davis was scratched from Saturday's game against the Pirates because of bronchitis, and outfielder Seth Smith is out with a hamstring injury.
"[Smith] could have played today, would have played during the season, decided to be careful with that today," Showalter said.
"Seth says he gets this every spring, and this isn't as bad as he normally gets it. I decided with all the time we have to slow play it a little bit. We'll see what tomorrow brings."
