BALTIMORE — The Baltimore Orioles have sent right-hander Chris Tillman to the bullpen, where they hope he can regain the form that enabled him to anchor the rotation since 2013.

Tillman began the season on the disabled list with a shoulder injury, won his first game on May 7, then went winless in his next 14 starts. He’s 1-7 with an 8.10 ERA.

Manager Buck Showalter hopes the move to the bullpen will help Tillman in the same fashion as Orioles righty Ubaldo Jimenez.

Showalter says, “It’s done good things for Ubaldo and some other people in the past.”

Tillman insists he feels fine, so it’s hard to explain his performance. His record was 16-7 in 2013, then 13-6 and 11-11 in 2015. Last year, Tillman was 16-6 and started the AL wild card game.

Showalter says, “It’s been frustrating for all of us, so we’re trying to figure out a way to get him back.”
