Baumann was optioned to Triple-A Norfolk following his spot start in the first game of Monday's doubleheader against the Blue Jays, Nathan Ruiz of The Baltimore Sun reports. He gave up three earned runs on eight hits and zero walks while striking out two in five innings to take the loss in the Blue Jays' 7-3 victory.
The innings total was a season high for Baumann in the majors, as he had typically been pitching out of the bullpen as a multi-inning reliever. He will continue to operate as a swingman or serve as organizational bullpen depth over the final month of the season.
