The last time Oliver Perez pitched for a New York team, he royally disappointed the Mets’ fan base by losing velocity and efficiency. As a starter, Perez had a handful of highly successful years on the back of his slider, but was always highly volatile due to command issues. By the end of his contract with the Mets, Perez’ velocity on his fastball was in a dramatic decline, and he was released during Spring Training of 2011.
The left-handed pitcher returned to Major League Baseball in 2012 with the Mariners. As a reliever, Perez found it easier to limit his walks, and his velocity returned in the short stints. In his first year back, Perez posted a 2.12 ERA with a 2.93 FIP in 29.2 innings, or 33 games. Not only was he highly successful versus left-handed pitchers, but he also held right-handed hitters to a .200/.279/.296 slash.
Perez returned to the Mariners in 2013, and although many of his peripheral stats were impressive, he finished the season with a 3.74 ERA in 53.0 innings.…
