With Huston Street activated today from the disabled list, Colorado has cleared roster space by designating reliever Juan Rincon for assignment. Troy Renck of the Denver Post was the first to report that Rincon was being "moved out" (Twitter link), and he also tweets that the team will know by tomorrow if Rincon will stay in the organization.
This is the second time that the out-of-options Rincon has been DFA'ed by the Rockies this season. He cleared waivers the first time, went to Triple-A Colorado Springs and was just recalled to the majors last week. The right-hander has appeared in just two major league games this season, but has a 7.25 ERA in 24 relief appearances for Colorado Springs.
