The 29-year-old Criswell appeared in seven games for Boston last season, going 1-0 with a 3.57 ERA. He was claimed off waivers by the New York Mets on Dec. 5 and designated for assignment Wednesday.

Diaz, 29, appeared in one game with the Mariners in 2025. He was 11-6 in 27 games with Triple-A Tacoma and led the Pacific Coast League with a 4.15 ERA.
