Dec. 23--The Cubs have released veteran infielder Brendan Ryan, who was acquired along with pitcher Adam Warren from the Yankees in the recent Starlin Castro deal.
The 33-year-old Ryan was the player to be named later in the trade.
In two other moves, the Cubs claimed left-handed reliever Edgar Olmos off waivers from the Orioles, and lost right-hander Yoervis Media on a waiver claim by the Pirates.
It was the team's second waiver claim on Olmos in three weeks. The Cubs originally claimed him off waivers from the Mariners on Dec. 4, but lost him to the Orioles on a waiver claim on Dec. 10.
The Cubs' roster remains at 40.
