The Cubs made a series of roster moves before the Christmas holiday.
The Cubs claimed pitcher Edgar Olmos off waivers from the Baltimore Orioles Wednesday, released infielder Brendan Ryan and had pitcher Yoervis Medina claimed off waivers by the Pittsburgh Pirates.
Olmos, a 25-year-old left-hander, came to the Cubs initially as a waiver claim on Dec. 4 from the Seattle Mariners, before the club put him right back on waivers and the Orioles scooped him up Dec. 10.
Olmos is 1-1 with a 5.21 ERA and 1.789 WHIP in 11 career MLB games (19 innings). He posted a 4.44 ERA in the minors, making 73 starts and 126 relief appearances.
Ryan came over as the player to be named later in the Starlin Castro-Adam Warren trade with the New York Yankees earlier this month. Ryan turns 34 in March and is known more for his defense than his bat (.610 career OPS). He was officially added to the Cubs' roster just last week.

Medina was designated for assignment by the Cubs Dec. 17. The 27-year-old right-hander appeared in five games (nine innings) for the Cubs in 2015, putting up a 7.00 ERA and 1.778 WHIP.
The Cubs acquired Medina from the Mariners in May as compensation for the trade that sent catcher Welington Castillo to Seattle.
The Cubs' 40-man roster now sits at 40.
