Romo (shoulder) expects to throw off a mound sometime next week, MLB.com reports.The right-hander came into camp nursing some shoulder soreness, which first crept up about a month ago, but the team hasn't felt the need to order an MRI to this point and Romo seems confident the issue will pass in relatively short order. He was able to play catch on flat ground and perform throwing exercises during the first three days of spring training workouts for pitchers and catchers.
