The Mariners formally announced their signing of righty Juan Nicasio. It’s a two-year, $17 million contract. The deal was agreed to last week but finalized today after Nicasio passed his physical. Nicasio, 31, spent last season with the Pirates, Phillies, and Cardinals, putting up an aggregate 2.61 ERA with a 72/20 K/BB ratio in 72 1/3 innings.
