BALTIMORE — Coming off his worst start of the season and experiencing more right shoulder discomfort during his latest bullpen session, Orioles starting pitcher Chris Tillman was placed on the 15-day disabled list on Wednesday.
Manager Buck Showalter said before Tuesday’s 8-1 win over Washington that the right-hander’s work day hadn’t gone well and that his next scheduled start against the Nationals was in jeopardy. On Saturday, the right-hander allowed six earned runs and walked five over a season-low two innings, but he said after the game that his shoulder was fine and told the training staff the following morning that it felt better than it usually does the day after a start.
Tillman received a cortisone injection after being examined by Dr. Leigh Ann Curl at Camden Yards. Showalter confirmed after the game that the 28-year-old would land on the DL in hopes that the rest will allow him to return at the end of the minimum 15-day period.
“I would have liked a little better results or response from the last outing, but it just didn’t respond very well,” Tillman said. ” We’re trying to be safe and get this thing in the rear-view mirror. That way, I’m not fighting it all year. I think it’s probably the best way to go about it.”
His last start was pushed back three days due to shoulder soreness that Tillman said he first experienced the morning after his Aug. 11 outing in Oakland.
Entering Tuesday ranked 12th in the American League with a 4.97 rotation ERA, the Orioles can hardly afford to lose their best starting pitcher in the midst of a tight division race with Toronto and Boston. Tillman is 15-5 with a 3.76 ERA in 26 starts covering 153 innings this season.
The Orioles recalled right-hander Mike Wright to replace Tillman on the 25-man roster and announced that right-hander Ubaldo Jimenez would start on Thursday.
