The Mets have signed leftyy Valerio de los Santos to a minor league contract, the Post has learned.

De los Santos has already played for five teams in the majors, including Colorado last year. He started two games for the Rockies, going 0-1 with a 5.63 ERA. He has appeared in 235 games, just four as a starter. The Mets are trying to find a second lefty in the pen to join Pedro Feliciano.

De los Santos would make $495,000 in the majors.
