Utility man Jake Fox, who was the club's backup catcher on Opening Day, is headed back to the Orioles and will join the club today in Minnesota.
With an injury to Chris Davis and the demotion of Josh Bell, the Orioles had just one true corner infielder on the roster, Mark Reynolds, who has become the club's starting first baseman.
Fox, who has spent parts of two seasons with the Orioles, can play corner infield and outfield and catcher.
The 29-year-old hit .274 with 12 homers and 57 RBIs in 67 games with Triple-A Norfolk. He also hit .188 in 19 games earlier this season with the Orioles.
After Monday's 4-1 win against the Twins, the Orioles demoted Blake Davis to Norfolk, creating the roster opening. Fox, however, is not on the 40-man roster, so a spot on it will have to be created.
The Orioles could move an injured player – such as Chris Davis – to the 60-day disabled list, but that would end his season and Davis (labrum tear) would like to be back in September.
Another option would be designating a player for assignment. One possibility could be right-hander Mitch Atkins, who has struggled recently at Norfolk.
