Brett Anderson (finger) threw a successful 30-pitch live batting practice session Tuesday. Anderson will throw another live BP session Friday and then a bullpen session Sunday. The left-hander thinks he'll be ready for a rehab assignment after that. "I felt like I could have gone longer today, which is a good sign," Anderson said. "I didn't have any fatigue, especially here in Denver. I feel good. I'll keep progressing and take it one day at a time."
