EDGE Analysis

Stevenson has been on the 10-day injured list since June 18 due to an oblique strain, but he's been ramping up his activity recently. The 27-year-old is expected to have a short rehab assignment, but the team wanted him to live reps before he's cleared to rejoin the major-league club.
