Orioles Gold Glove right fielder Nick Markakis, who has been bothered for months by what he initially thought was a deep bone bruise near his abdomen, had surgery Thursday to repair an abductor muscle and his rectus abdominis, also known as the "six-pack" muscle. Despite the extensive muscle damage, Markakis hopes to play in exhibition games by mid-to-late March and expects to be ready for Opening Day, April 6 at Camden Yards against the Minnesota Twins. He has already spoken to manager Buck Showalter about a potential plan that will ease him into spring training, which begins in earnest with the exhibition opener March 5. "Spring training is what it is. I think if I get two solid weeks in at the end of games, I'll be fine," Markakis said. "It doesn't take me long to get back in the swing of things. My main concern is just getting my strength back now."
