With four days remaining until its season opener at Boston City FC Sunday, Cosmos B added four players to its roster Wednesday.

The additions included returnees midfielder Giuseppe Barone and goalkeepers Hector Guerrero and Kevin Tenjo.

The National Premier Soccer League team also signed New Hyde Park, N.Y. native Billy Stevens, a four-year starter at the University of Michigan.

Barone played his college ball at St. Francis Brooklyn College, while Guerrero hails from Briarcliffe College. Tenjo most recently played with Universidad Central.

“Our roster for the NPSL season is just about complete,” Cosmos B head coach Carlos Mendes said. “We’re still looking for one or two attacking options at forward and on the wing, but I like where we are right now. We’ll be ready for this weekend.”

Cosmos B takes on Boston City F.C. at Malden Catholic High School in Malden, Mass. Sunday at 6 p.m. The team will meet the Brooklyn Italians in a Lamar Hunt/U.S. Open Cup play-in round match at Long Island University Brooklyn Sunday, May 6 at 8 p.m.
