High school outfielder Brent Warren goes off the board to Oakland in the 27th round with the 814th pick. Warren, from Iowa, had a serious heart condition in the middle of high school, requiring major surgery. Once diagnosed, Warren wasn’t sure if he’d be able to play baseball again, but he has now made a full recovery and is committed to play for Oregon State next season. Warren is a plus runner in the outfield and will be an impact player for the Beavers right away.
