BALTIMORE -- The Orioles optioned right-hander Steve Johnson, who was recalled from Triple-A Norfolk when Jason Hammel was placed on the 15-day disabled list on Sunday, back to Norfolk after Sunday's game against the Tigers.
Johnson made his Major League debut in Sunday's 4-0 loss to the Tigers, giving up one run on one hit in two innings. He pitched the eighth and ninth innings.
Johnson walked his first two batters in the eighth before retiring the next three. He struck out Don Kelly and Austin Jackson to close the inning, drawing a huge ovation from the hometown fans. The right-hander then allowed a solo homer to Miguel Cabrera in the ninth.
"Just walking off the field in the eighth inning, getting the strikeout and getting out of the jam and having the fans get behind me, that was a pretty special moment," Johnson said. "That's something I'll take with me."
Steve's father, Dave, pitched for the Orioles from 1989-91. The pitcher is a Baltimore native.
They became the sixth father-son duo to play for the Orioles.
Right-handed reliever Stu Pomeranz was scheduled to start a rehab assignment on Sunday, but he had what O's manager Buck Showalter deemed "a hiccup" with his back and will need another day or two. Pomeranz has been sidelined with a left oblique strain since the end of May.
Monday's starter, Chris Tillman, was with the team on Sunday, and is expected to be activated to start the series opener in Minnesota. Tillman, who had his original start pushed back a day due to back spasms on Thursday, played catch on Saturday with no problems.
