Added To 40-Man Rosters: O'Brien, Stauffer, Hill, Baron, Ramirez

With Triple-A seasons coming to a close, there’s been another wave of players whose contracts of have been selected to their respective teams’ 40-man rosters. Here’s a list of today’s 40-man moves…

  • The D-Backs announced that they’ve selected the contract of slugging prospect Peter O’Brien. The catcher-turned-outfielder was the key piece that Arizona picked up from the Yankees in last summer’s Martin Prado swap. The 25-year-old O’Brien batted .284/.332/.551 and belted 26 homers this season for Triple-A Reno. The knock on O’Brien has long been his lack of a true position.
