The team originally placed Jepsen on the disabled list with a right shoulder strain. The right-handed pitcher made three rehab outings, and feels ready to pitch in high-leverage situations.
Jepsen threw 3.2 innings of relief for Los Angeles earlier in the season before heading to the DL. The reliever allowed four earned runs on five hits, striking out six while issuing one walk. Jepsen proved to be a solid option for the Angels out of the bullpen last season, posting a 3.02 ERA in 49 relief appearances.
The team designated Bucker for assignment the day after he pitched a solid spot start for the Angels against the Kansas City Royals. The right-handed shutout the Royals for five innings, surrendering two hits while striking out two batters.
Buckner said that he is receptive to staying in the Angels organization if he clears waivers, and that he understood the reasons for the roster move. If the starter clears waivers he will likely head to Triple-A Salt Lake City, where he is 4-2 on the season with a 4.56 ERA.
