A year ago, Donnie Hart was getting ready for Orioles minor league camp. Hart, who was a 27th round draft choice in 2013, progressed in the system but only three games at the Double-A level.
The 26-year-old left-hander returned to Double-A Bowie to start 2016, and after a 3-1 record with a 2.72 ERA, he was in the big leagues.
With the Orioles, Hart gave up just one run in 18.1 innings, and he now looks like he's left the minors behind.
