Pregame notes on Roberts, Wada, Steve Johnson and more

Orioles second baseman Brian Roberts hasn't been cleared for baseball activities, and he won't be ready to come off the disabled list when eligible on Saturday. It was considered a long shot anyway after an MRI revealed a ruptured tendon behind Roberts' right knee. He sustained the injury on April 4. "He's feeling a little better each day," said manager Buck Showalter. "Still not doing baseball activities, though, so I would think the 20th isn't going to be an option for us." Steve Johnson and Tsuyoshi Wada will pitch again Thursday at extended spring training. Johnson, expected to go four innings, could begin an injury rehab assignment after this outing. The Orioles' clubhouse closed to the media at 3:50 p.m. for a security meeting that included Doug Duennes, executive vice president of business operations. The meeting was scheduled following yesterday's explosions at the Boston Marathon. "Just going over some things," Showalter said. "The good thing is, there's already been a lot of precautions, a lot of things going on here they may not have been aware of. "Just wanted to, as the players go home, talk to their families. There's already been some stuff going back and forth. Make sure they understand some of the things that have been done and things that are being done. And some of the things on the road. Get ahead of some things." Showalter said the Boston Marathon tragedy "certainly strikes home," considering that the Orioles played at Fenway Park last week and their hotel was close to the site of the explosions. "We walked right across that area going to the Jackie Robinson movie ("42") that (Adam) Jonesy was so good to do for us. We went right through there," Showalter said. "Its not something that's happening in some other country, so to speak. Tragic." Asked whether he believes fans will be uneasy going to ballparks, at least for the next few weeks, Showalter replied, "I don't know. It's uncharted territory to some extent. But we all take precautions. There's a reason why that hasn't happened, and a lot of things go on that we won't see. We've got a lot of confidence in the people who are equipped and trained for that. But in all walks of life, we take precautions. There's always something that's somewhat in the back of your mind. "Same thing with you. You went to work and you probably looked around. There's a lot of challenges there. It's not just us. But at some point, in all our lives, you have to have some confidence in people who do what they do. We're not going to walk around and ... personally, you live your life. We're not going to let that win. "Of course, I don't have the majority of my life ahead of me. But we do what we do. You take risks getting in your car every day. It's just part of our lives." Executive vice president Dan Duquette's ex-wife, Sharon, volunteers at the finish line of the Boston Marathon every year. Their son, Daniel, tweeted yesterday that she's fine. Orioles designated hitters are 3-for-40. Rays designated hitters are 3-for-38. They're batting a combined .077 with two homers and six RBIs (five by the Rays). The Orioles had runners on base for their first seven home runs. Seven of the last eight have been solo shots.
