The 36-year-old Perez signed a minor league deal with the Reds earlier this offseason, but allowed ten earned runs in just 6 2/3 innings and as such was not named to the club’s opening day roster; the club released him on March 22nd. But perhaps the Yankees found some small reason for optimism in his 2:1 ground ball to fly ball ratio and nine strikeouts across those innings.
Perez has long been effective against opposing left-handed hitters. He’s faced them a total of 1,541 times, and they’ve managed just a .228/.318/.365 batting line against him. Even as he’s aged, he’s maintained that skill, as evidenced by his .227/.301/.364 batting line versus lefty opponents in 2017. On the whole last season, Perez posted an impressive 10.64 K/9, but with a 4.64 ERA.
