Francisco Liriano's contract with the Pirates includes an $8 million vesting option for 2014.
Liriano's option will vest at $6 million if he does not spend 120 days on the disabled list due to an injury to his right arm, according to a copy of the deal.
Liriano would have gotten the full $8 million if he was not on the DL for 150 days, but the injury sidelined him until May 11.
The option will vest at $5 million if he does not spend 90 days on the DL due to the specific injury.
