Archer had himself a beneficial heater in 2015, which suddenly lost its luster in 2016, getting slapped with a horrendous -14.0 pVal. What went wrong? Simply put, the pitch wasn't missing bats up in the zone like it used to, with a 15 point difference in contact rate for elevated heaters. That's a huge difference and could have been a product of losing a tick off his velocity, or possibly an element of deception was missing. Either way, he'll have to reclaim his touch to climb back to his seat among the AL's best starters.
