Perez has spent parts of 6 seasons in the Minors, and owns an unimpressive 32-32 record with a 4.12 ERA over 123 appearances and 112 starts. He had shown the ability to strike out more than a batter per inning, but for his career owns a 7.5 K/9 against minor league hitters. Perez did not transition well into the Majors, with an ERA over 5 across 38 innings in 2012. At just 21 years old, I'm sure that did not surprise the Rangers organization. Last season, he made 20 starts and went 10-6 with a 3.62 ERA. This season, Perez has made 5 starts and allowed just 6 runs over 38 innings, none in last 26 IP.

Perez is getting 60% of batted balls on the ground,best in baseball behind teammate Robbie Ross and Cincinnati Reds pitcher Mike Leake. He is not overpowering and his fastball is usually in the low 90s, but he is able to locate it so well that he throws it 62% of the time! He will then mix in his change-up (17.5%), slider (11%) and curve ball (9.5%) to force those ground balls. Much like real estate, pitching is all about location, location, location.

Prior to his last start, FanGraphs had a great article about his bad fastball and awesome sinker.
