Profile: If it was possible to improve on his previous three seasons in 2016, Herrera did so. The righty's 2.75 ERA was right in line with where it had been, but the gains were in the peripherals. Herrera's strikeout rate jumped from 22% to 30% and the walk rate (long his bugaboo) was slashed in half (down to 4% in 2016). There's likely a bit of chicken-versus-the-egg there as improved control forced hitters to attack nasty stuff while nasty stuff meant it was harder for hitters to lay off. Regardless, Herrera's value is set to skyrocket in 2017. Perhaps because of his admirable performance filling in for an injured Wade Davis in 2016, the Royals shipped Davis to the Cubs in the off-season, leaving the ninth inning driver's seat all to Herrera. A young reliever with a 97 mph fastball and great peripherals? Yes, please.(Colin Zarzycki)

The Quick Opinion: On the face, Herrera looked like the same steady middle reliever in 2016. Under the hood, though, a dramatic increase in strikeout rate coupled with improved command led to much more elite peripherals. Now seemingly with the Royals' closing gig in his grasp, Herrera has the potential to be a Tier 1 fantasy reliever at Tier 2 prices.
