Tonight The Tulsa Drillers host the Colorado Rockies in an exhibition game at ONEOK Field. Not only will it will be the first appearance in Tulsa for the Rockies since the 2003 season when the club first became the major league affiliate for the Drillers, but it'll also open ONEOK Field for the 2011 baseball season here in Tulsa. First pitch is scheduled for 6:05pm, but the gates to will open at 4pm to allow fans the opportunity to watch the Rockies' batting practice session. Cool!
