The Baltimore Orioles activated right-handed pitcher Jason Hammel from the disabled list and recalled right-hander Steve Johnson from Class AAA Norfolk on Thursday.
Hammel, 31, was out since late July with a forearm injury. He is 7-8 with a 5.20 ERA and 1.51 WHIP this season. He may rejoin the rotation eventually but is expected to work out of the bullpen initially.
Johnson, 26, went 2-3 with a 4.11 ERA and 1.24 WHIP in 10 appearances at Norfolk. He had a 7.82 ERA in 12 2/3 innings in a previous stint with Baltimore earlier this season.
