To make room for Redmond on the 40-man roster, the club designated outfielder Trayvon Robinson for assignment. Robinson was acquired in November when the Orioles dealt Robert Andino to Seattle. But the Orioles have signed several reserve outfielders since then -- including Chris Dickerson -- and Robinson’s spot became less secure.
In addition, the club announced that catcher Luis Rodriguez, who was designated earlier this week for Russ Canzler, has cleared waivers and been outrighted to Triple-A Norfolk. Rodriguez will be a non-roster invitee to spring training.
Redmond, 27, started one game for the Reds last season, giving up four runs in 3 1/3 innings versus the Chicago Cubs in August. Originally drafted by the Pittsburgh Pirates in 2004, he was dealt to the Atlanta Braves for Tyler Yates in 2008 and then to the Reds for Paul Janish last July.
He was a combined 8-11 with a 3.63 ERA in 26 games (25 starts) at Triple-A for Atlanta and Cincinnati last year. He is 71-61 with a career 3.58 ERA in 207 minor league games (200 starts) in eight seasons.
Robinson, 25, has played in 90 games with the Seattle Mariners in the past two seasons, batting .215 in 319 plate appearances.
