The Orioles optioned right-hander Miguel Castro to Double-A Bowie after Sunday's game. Castro threw three scoreless innings in two appearances with the Orioles, allowing no hits, walking three and striking out one. … With just-recalled Paul Janish starting Sunday, shortstop J.J. Hardy received his second Sunday off in a row. Hardy has started 38 of the team's first 41 games, but that doesn't signal a need for new time off, Showalter said. "J.J. is fine either way," he said. "I just think that I want to get Paul in the mix a little bit. We've got a pretty long stretch coming up where we're going to need everybody." … After hitting a double in his first at-bat on Sunday, rookie outfielder Trey Mancini has reached safely in 11 of 14 games in May and is hitting .388 (19-for-49) this month. … Outfielder Mark Trumbo had his 16th multihit game of the season. He entered the day tied for fifth in the AL in multihit games.
