Quick update on Chen

Wei-Yin Chen, on the disabled list since straining his right oblique during a May 12 start in Minnesota, was scheduled to do some light throwing today in Sarasota. Apparently, the session went pretty well, judging by a tweet that Chen sent a few minutes ago. Using Google translate, it read as follows: "Today began to pass the ball, and the progress of all the best" I'm taking it as a positive step for Chen. There's no timetable for Chen's return to the active roster. The Orioles need him to throw off a mound without discomfort and go on an injury rehab assignment. The Orioles will have plenty of time to figure out how to make room for Chen in a rotation that currently includes Jason Hammel, Miguel Gonzalez, Freddy Garcia, Kevin Gausman and Chris Tillman, who starts tonight in Houston. Tillman has never faced the Astros, who swept the Orioles in a three-game series in 2003 by a combined score of 28-11. Carlos Pena is 1-for-7 with a double against Tillman. Trevor Crowe is 0-for-1. That's it. Tillman has allowed eight home runs in his last three starts and 11 in his last five. Bovada (www.Bovada.lv) places the Orioles' odds of winning the World Series at 18/1, and their odds of winning the American League pennant at 10/1. Bovada places the odds of Chris Davis winning AL Most Valuable Player at 3/1, just behind Detroit's Miguel Cabrera (1/1), and the odds of Adam Jones winning it at 15/1.
