O'Brien caught his first game of the season at Triple-A Reno on Wednesday, FOX Sports Arizona's Jack Magruder reports. He also hit is eighth home run of the season, so O'Brien's ability with the stick is not what is at question here. O'Brien started the year playing the outfield in an attempt to give him a break from the mental aspect of catching, but his quickest route to the big leagues would be as a catcher, so this is good news. However, there's also a fairly decent chance that his defense behind the plate becomes an issue, or his offense suffers because of his attention to catching. It will be an intriguing situation to monitor going forward.
