The Orioles today announced that they have reinstated right-hander Chris Tillman from the 15-day disabled list and optioned infielder Yamaico Navarro to Triple-A Norfolk. Tillman, 24, was placed on the DL on March 28, retroactive to March 22, with a left abdominal strain. Navarro, 25, was recalled yesterday but did not play. He was acquired from Pittsburgh on November 30, 2012 in exchange for minor league right-hander Jhondaniel Medina. Navarro batted .276/.417/.379 in 29 spring training at-bats for the Orioles after hitting .279/.366/.491 in 66 games with Triple-A Indianapolis last season and going 8-for-50 with the Pirates.
