O'Brien launched his seventh home run of the season Tuesday as part of a 3-for-4 day for Triple-A Reno. O'Brien is enjoying life in the friendly batting environments of the Pacific Coast League, posting a .397/.436/.781 line in the early going. He is still playing exclusively in the outfield, which makes his route to Arizona a bit tougher as they have plenty of outfielders at the moment. O'Brien is making a lot more contact and has reduced his strikeouts significantly so far, but with just three walks drawn to date, he still has stuff to work on at the plate.
