The Blast has signed Edwin Cubillo, a 27-year-old defender who played with Blast forward Diego Zuniga on the Costa Rica national futsal team.
"Edwin is a talented, attacking left-footed defenderwho we think will be a great addition to the team," Blast coach Danny Kelly said in a statement. "Once he gets familiar with our game, we feel he has the potential to play an important role with the Blast in terms of helping us compete for a championship."
To make room on the active roster for Cubillo, the Blast placed Kaoru Forbess (foot) on the inured reserve list.
The Blast, which has clinched the Major Arena Soccer League's Eastern Division with a 13-0 mark, play at the Las Vegas Legends on Feb. 6.
