I did find where Katie Woo said last week that O’Brien has started a throwing program. That doesn’t mean much but I guess it’s something. The bullpen really can’t get too much better. These guys just extend our depth. Carlson is almost certainly an upgrade though – even if that’s in RF over Burleson. It’s debatable whether he’s an upgrade over Siani and his elite CF defense. Edman might as well go on the 60-day IL so we can try to grab the next Richie Palacios.
