MIAMI -- The Marlins signed lefty reliever Craig Breslow to a Minor League contract with an invitation to Spring Training on Monday.
Breslow, 35, is a 10-year veteran who spent the last four seasons with the Red Sox. The deal includes the left-hander earning $1.5 million if he makes the big league club. The agreement and contract terms was first reported by WEEI.com.
Breslow also has a late March opt-out, which is common for non-roster invitees. The veteran will compete for a bullpen setup role.

The organization is aiming to add as much depth as possible. Now that there is another reliever in camp, the attention also is on bringing in another starter.
For that to occur, it has to make sense financially. The Marlins are willing to wait, even if it means reaching an agreement after spring practices begin.
Like many clubs, the Marlins are basically at their payroll limit, and they're primarily seeking pitchers willing to sign a Minor League contract with a Spring Training invitation.

The Marlins already have addressed their primary offseason need by signing left-hander Wei-Yin Chen to a five-year, $80 million contract to be their No. 2 starter. They've also brought in rotation depth by signing right-hander Edwin Jackson.
Miami wasn't in the market for many position players, but the club did fill a void of a right-handed-hitting infielder when it signed Chris Johnson, who will back up at first base and third.
The Marlins are open to signing another starter to compete for a back-of-the-rotation spot. Free agents Kyle Lohse, Aaron Harang and Alfredo Simon are candidates. Indications are they also may be willing to wait for a big league contract rather than risk signing a Minor League deal with no guarantee of making an Opening Day roster.
For those veterans, it may be in their best interest to see what happens after Spring Training begins and potential roster spots open, rather than sign with a club without a big league contract now.
Tim Lincecum and Cliff Lee are two other possibilities. The Marlins plan to attend their workouts. Miami could be open to signing either to an MLB deal, but it would likely have to be a low base salary, plus incentives.
