The Rangers have announced that they will raise the height of the rails at Rangers Ballpark in Arlington. The move comes as part of new safety initiatives at the facility following the death of fan Shannon Stone. Stone, 39, fell over the railing in left-center July 7 as he attempted to catch a ball thrown by outfielder Josh Hamilton. "The safety of our fans is our top priority," said Rangers CEO and president Nolan Ryan, who was released from the hospital Tuesday after undergoing tests that determined there were no new developments in the recurrence of a previous heart condition. "The initiatives we are announcing today for Rangers Ballpark in Arlington will help to ensure that we meet that priority."
