Aramis Ramirez will officially file for free agency after telling the Cubs he will decline his part of the mutual $16 million option.

The Cubs exercised their half of the mutual option on Sunday night. Ramirez has until 10:59 p.m. Tuesday to officially file for free agency.

Ramirez said in September he expected to decline if the Cubs exercised the option, holding out for a long-term deal on the free agent market.
