Perez, 26, is completing his sixth season in the majors. Across 31 starts, he has a 4.83 ERA with a 113/61 K/BB ratio over 179 innings. The former top prospect has not quite lived up to expectations but has at least been able to have two full, healthy seasons in 2016-17.
Perez inked a four-year, $12.5 million contract extension with the Rangers in November 2013. The deal included three option years for 2018-20. His 2019 option is worth $7.5 million with a $750,000 buyout and his 2020 option is worth $9 million with a $250,000 buyout.
