In the midst of their worst losing streak of the season, the Orioles will now be without their most durable player for as long as a month. Starting rightfielder Nick Markakis will miss two to four weeks with a broken bone in his right wrist. Markakis suffered a fractured hamate bone and is scheduled to have surgery Friday morning performed by nationally-renowned hand specialist Dr. Brian Schofield in Sarasota. Orioles manager Buck Showalter said he was actually pleased with the news.
