• Jered Weaver (broken left elbow) threw 40 pitches in his second bullpen session on Saturday, incorporating fastballs and changeups, but pitching coach Mike Butcher said they're "still working through some things."
"Right now, we're trying to build arm strength, build endurance and just see where we're going," Butcher said. "It's like a day-to-day thing, where his progression is going to lead. We don't want to rush anything."
• Shortstop Erick Aybar and lefty reliever Scott Downs, both of whom exited Thursday's game with injuries, are on the mend. Aybar took batting practice on Saturday and could return by Monday's series opener against the Royals, if his tight right hamstring continues to improve. Downs, nursing a right foot injury, went through pregame on Saturday and struck out Alejandro De Aza to record the last out of the seventh inning that evening.
• Kevin Jepsen, who's been out since April 11 with a strained right lat, threw a 20-pitch bullpen and said he "felt awesome." Jepsen doesn't have any more pain, but will need to pitch several bullpens and at least face hitters -- perhaps even go out on a rehab assignment -- before getting activated.
