For the first time this season the Orioles have won four in a row. They’re eight games over .500 for the first time and are now tied for the lead in the American League East. The Orioles’ 5-3 win over the Kansas City Royals before 12,344 on Wednesday night, had some decent pitching, good defense and something new for the team this year, aggressive baserunning. Can this team be called a methodical one? “I don't find anything methodical about it. I find it just good baseball. It's what allows you to be consistent,” manager Buck Showalter said. “That's just the description of the things you have to do to be successful. Pitch well and with a good tempo, and catch it, and don't walk people. And if you get some people out there, you better take advantage of it. If that's the description, than I'm in." Chris Tillman pitched six innings, was an out away from a statistically solid performance, but a two-run home run by Kansas City’s Mike Moustakas with two outs in the sixth made the game a little close. “You get your team deep in the ballgame, you feel good about it, whether or not you had you featured your best stuff. You give your team a chance to win, and get deep in the game,” Tillman said “I'd like to get deeper, but you feel good about it.” Tillman (3-1) pitched six innings, allowing three runs on five hits. Before the game, Showalter spoke with Brian Roberts, who will undergo surgery to repair his right hamstring on Thursday. The surgery will be performed by Dr. Daniel Cooper. Roberts, who hasn’t played since Apr. 4, is expected to miss an additional six weeks. “This is the best chance for him to get back and not have an issue with it again,” Showalter said. “I know what his goals are. He's very frustrated by it, as we are, but Brian Roberts is going to come back and make a contribution to this club this year. I've got a good feeling about that."
