BALTIMORE -- On the heels of Monday's doubleheader, the Orioles recalled left-hander Donnie Hart and selected the contract of right-hander Jhan Marinez from Triple-A Norfolk prior to Tuesday's game against the Yankees at Oriole Park at Camden Yards. To clear roster spots, Baltimore optioned righty Ryan Meisinger and No. 15 prospect Yefry Ramirez to Triple-A.
Orioles starters have been unable to go at least six innings in each of the past five games, straining the club's bullpen arms. If used, Marinez will make his Orioles debut after signing as a free agent with the club last November.
"He's been pitching well down there, I think 10 or 11 outings without giving up a run," O's manager Buck Showalter said of Marinez, who was a non-roster invitee in big league camp this spring. "Started out a little shaky, but he's been solid. He's our best option down there, he's been closing down there, doing well."
Marinez has compiled 11 saves and a 2.78 ERA in 38 appearances (one start) for Norfolk this season. The 29-year-old righty has a 3.43 ERA over 95 big league outings, most recently in 2017 with the Rangers after being selected off waivers from the Pirates.
Hart, on the other hand, has been seemingly back and forth between Baltimore and Norfolk weekly this season, appearing in eight games at the Major League level. The 27-year-old left-hander holds a 3.68 ERA in 7 1/3 innings for the Orioles in 2018.

On the flip side, Meisinger, who made his Major League debut earlier this season, pitched three perfect innings in Monday's nightcap, coming in relief of starter Ramirez in the fifth.
"He's not going to be able to pitch for me for three days," Showalter said of Meisinger following the extended outings. "So get him back down there [in Triple-A] pitching. Just had a need for a couple arms tonight."
