The Orioles placed Kremer (oblique) on the 10-day injured list Monday, Roch Kubatko of MASNSports.com reports. Manager Brandon Hyde said he expects Kremer to miss at least 3-to-4 weeks.
The 26-year-old was slated to make his season debut Tuesday against the Brewers, but after hurting his oblique Sunday while warming up, he'll be placed on the shelf. Though the Orioles likely aren't counting on Kremer to return in April, Hyde suggests that the right-hander isn't considered a candidate to move to the 60-day IL. The Orioles haven't announced who will start in Kremer's place Tuesday, but Mike Baumann, Spenser Watkins and Alexander Wells are the most likely candidates to step in.
