You can understand why he went to the slider more as his four-seamer, which generates excellent velocity at 96.9 mph on average, lost command. A spike in BB% from 4.0 in 2018 to 14.7 in 2019 luckily didin’t hurt his bottom line. But it is something to watch. Giles should still be an elite closer in Toronto this season.
Giles threw his slider more than his four-seamer for the first time in his career to date. And so he should, it is his primary weapon and yielded a 56.1 K% in 2019, placing him among the league’s top relievers. It is particulalry potent against righties, trapping them inside with it’s depth.
As much as he’s a little tapped, Giles does have some giddy-up on his fastball. That didn’t stop hitters from launching it every which way. Maybe if he does a little yoga or something that will help his 97 mph fastball out so it can do what it’s supposed to—get hitters out.
This slider is why Giles is still considered a very good reliever. Nearly three out 10 hitters were swinging and missing at it. With the depth this thing gets, it’s hard to imagine anyone actually getting wood on it, never mind base hits.
