Jered Weaver threw 30 pitches from about halfway up a bullpen mound in Los Angeles on Monday, giving his injured lower back its biggest test since he landed on the disabled list May 29. "It feels good, so obviously I want to start pushing it a little bit," the right-hander said. Weaver will have another bullpen session Tuesday and will throw a simulated game by the end of the week. If all goes well, he could start for the Angels next week.
