Orioles optioned RHP Oliver Drake to Triple-A Norfolk.
Drake has had back-to-back rough outings, allowing six runs in only 2 1/3 innings against the Padres earlier this week. The 29-year-old should have more chances in Baltimore as the year rolls on.
Orioles optioned C Francisco Pena to Triple-A Norfolk.
He's no longer needed now that backup catcher Caleb Joseph is back after missing a month with a groin injury. Pena hit .219 with one homer and three RBI during his nine-game stint with Baltimore. He'll be called up again the next time an Orioles catcher gets hurt.
Orioles activated C Caleb Joseph from the 15-day disabled list.
The Orioles made room for Joseph by optioning Francisco Pena to Triple-A Norfolk. Joseph needed a month to recover from a testicular injury that required surgery. He'll return to his usual backup role behind starting catcher Matt Wieters.
Orioles activated RHP Vance Worley from the 15-day disabled list.
A strained groin sidelined him for about two weeks. The 28-year-old has enjoyed a successful year out of the bullpen, providing a 2.66 ERA over 40 2/3 innings. He'll continue to work as the Orioles' primary long reliever.
Andrew Heaney (elbow) will undergo season-ending Tommy John surgery on Friday.
The operation will be performed by Los Angeles-based surgeon Dr. Neal ElAttrache. Heaney received a stem cell injection two months ago in hopes of avoiding Tommy John surgery but it didn't make much of a difference. It's possible Heaney could return late next season but spring training of 2018 might be a more realistic timetable.
Desmond Jennings left Thursday's game against the Tigers with a tight left hamstring.
Jennings doubled in his lone at-bat before exiting in the third inning. Brandon Guyer, who started the game in right field, took over for Jennings in center with Nick Franklin substituting in right. Jennings is day-to-day.
Orioles purchased the contract of RHP Chaz Roe from Triple-A Norfolk.
Roe was called up to replace T.J. McFarland, who is headed to the disabled list with a knee injury. The 29-year-old has recorded a stellar 2.39 ERA in 33 outings for Norfolk this season. Roe made 36 appearances out of the Baltimore pen last year while posting a 4.14 ERA in 41 1/3 innings.
Orioles placed LHP T.J. McFarland on the 15-day disabled list with a knee injury.
McFarland had been pitching through the injury but the Orioles decided giving him an extended rest was the best course of action. Chaz Roe has been called up to take McFarland's spot in the Orioles' bullpen. McFarland carries a disappointing 5.63 ERA over 15 outings this year.
