The Mariners have signed 30-year old lefty starting pitcher Oliver Perez to a minor league deal. Perez pitched in 16 games (15 starts) in AA-ball last year and he was 3-5 with a 3.09 ERA and a 1.39 WHIP. Perez last pitched in the majors back in 2010 with the Mets. Perez has pitched in 206 games (195 starts) in his first 9 years in the majors and he is 58-69 with a 4.63 ERA and a 1.48 WHIP. Perez has only given up 1,019 hits in his first 1,111 2/3 innings so far in his major league career while whiffing 1,126 batters. But, he has also walked 628 batters which is way too many. If Perez is healthy and throwing strikes this spring, he could win a job at the back end of the Mariners’ starting rotation.
