Profile: During his rookie campaign of 2013, Perez managed a 3.62 ERA for 124.1 innings throwing 93 mph from the left side with a plus changeup, decent slider, and show-me curveball, though the low strikeout rate, solid-average walk rate, and high home run rate yielded a 4.23 FIP. The follow up was cut short after just eight starts and a Tommy John surgery that essentially cost him the next two seasons (130 innings in 2014-15). The 2016 season saw his already-weak strikeout rate drop further (12%) while his walk rate climbed to 9% and his home run rate ticked back toward the 2013 level (0.8) en route to a 4.39 ERA/4.50 FIP combo. He’s simply not good enough against righties, and the quickest way to fixing that might be trusting the high fastball more. Since 2014, his 16% of fastballs in the upper third of the zone to righties is lowest among 54 lefties with at least 1000 fastballs thrown. Yet his .485 OPS on the 90 plate appearances ending on those pitches is sixth-best, though it’s weak contact all the way as his 10% strikeout rate is third-worst and painfully below the 26% average. Scrapping the curveball against them would also help (career .949 OPS, albeit in just 115 PA), though he seems set on revamping it instead. He hasn’t even reached 500 MLB innings yet so there is some time, but it’s quickly running out. (Paul Sporer)

The Quick Opinion: Perez ate up nearly 200 innings with a league-average performance after being limited to just 130 innings in 2015-16 thanks to Tommy John surgery. The 26-year old lefty was lauded as a prospect, but has failed to pay off on the potential. There are some intriguing aspects, but he needs to make sharp improvements — and fast — if the prospect hype is to be met.
