The 33-year-old Jones signed with the Reds on Feb. 5, getting a chance to win a reserve spot. He went only 4-for-45 (.089) in spring training, and was reassigned to the minor league camp Monday.
The Reds optioned Hopper and Thompson to Triple-A Louisville. Hopper batted .132 this spring, costing him a shot at a reserve role. The 23-year-old Thompson jumped from Class A to Triple-A last season. The Reds want him to get more experience in the minors.
