Torrealba, 30, left the club June 2 after his son and two other family members were kidnapped in Venezuela. All family members were returned safely. Torrealba has missed 27 games, but he will be active for Friday night's opener of a three-game set with the D-backs at Coors Field.
Phillips, 32, made it a tougher decision for the Rockies by hitting .310 with one home run and seven RBIs in 13 games. He was called up May 24 when Chris Iannetta suffered a hamstring injury, and shared time with Torrealba before the incident, Edwin Bellorin -- who was called up after Torrealba left -- and Iannetta once he returned. The Rockies were 9-4 in Phillips' starts.
Colorado has 10 days to determine Phillips' status. If he is not claimed by another club during the brief waiver period, he can be returned to Triple-A Colorado Springs.
Major League Baseball granted the Rockies a brief rehab period for Torrealba, who was hitting .230. Torrealba went to Colorado Springs and hit .267 (4-for-15) in four games before returning to the club this week.
