Edgar Olmos has had a busy offseason.
The 25-year-old left-handed pitcher has been designated for assignment five times this winter, being claimed off waivers on four separate occasions.
The Cubs accounted for two of those claims (once on Dec. 4, then again on Dec. 23), but they opted to designated Olmos for assignment Friday afternoon to make room for waiver claim C.J. Riefenhauser.

Olmos even came to Cubs Convention in January.
Riefenhauser turned 26 last month and has appeared in 24 games for the Tampa Bay Rays over the last two seasons, posting a 6.30 ERA and 1.55 WHIP in 20 innings.
Riefenhauser had a career 2.77 ERA in the minors, including some work as a starting pitcher (42 starts, 149 relief appearances).
