Jays manager Gibbons has a unique contract.

The contract of Blue Jays manager John Gibbons includes a rolling option that means he won’t face a season as a lame-duck manager, Shi Davidi of Sportsnet.ca reports. Gibbons, who signed for two years plus an option earlier this offseason, has a unique clause in his contract. As long as the Blue Jays don’t fire Gibbons by January 1st of a given year, his option will vest for the following season and the sides will add another option to the contract. The unique deal means Gibbons will have a two-year contract as long as he’s managing the team. It’s reminiscent of the perpetual option on the deal between the Red Sox and [Tim Wakefield], though it appears to be the first of its kind for an MLB manager.
