You have to like a sports agency that announces when its clients sign a contract. Welcome to the Twitter world. CAA Baseball has tweeted that reliever David Riske agreed to a minor league deal with the Orioles that includes an invitation to spring training. Riske appeared in 23 games with the Brewers last season, compiling a 5.01 ERA before being released in August. He already got his Tommy John surgery out of the way in 2009. Riske is 20-20 with a 3.67 ERA in 11 seasons with the Indians, Red Sox, White Sox, Royals and Brewers. Riske, 34, is probably ticketed for Triple-A Norfolk unless there's an injury. It's getting pretty crowded in the Orioles' bullpen, which could include right-handers Kevin Gregg, Koji Uehara, Jim Johnson, Jeremy Accardo and Jason Berken. And don't forget Rule 5 pick Adrian Rosario (as I've done a few times.) But competition is a good thing.
