Raquet was optioned to Triple-A Norfolk on Monday, Roch Kubatko of MASNSports.com reports.
Raquet made one appearance during his latest stint in the big leagues, tossing a scoreless inning Tuesday against the Cubs. He's posted a 3.04 ERA and 1.37 WHIP with 28 strikeouts over 26.2 innings this season at Triple-A, so he should have a chance to be back up with Baltimore later in the campaign.
