The Orioles are closing in on a deal with Koji Uehara, according to Jeff Zrebiec of the Baltimore Sun (Twitter link). They have also offered Kevin Gregg a two-year deal, the Sun reports. Six teams were interested in Uehara as recently as yesterday, so the Orioles have presumably made a competitive multiyear offer if they're near an agreement.
The 35-year-old right-hander posted a 2.86 ERA with 11.3 K/9 and 1.0 BB/9 in 44 innings of work last year. He made trips to the disabled list because of elbow and thigh injuries, but few pitchers have a strikeout to walk ratio as impressive as Uehara's.
