What’s behind the subtle brilliance of Blue Jays’ Berrios’ bounce-back season

TORONTO – José Berríos has been higher this season than he was in 2022 by each metric that issues.

He’s putting out extra hitters, strolling fewer, conserving the ball within the park extra successfully and permitting a considerably decrease common exit velocity. The result’s a greater ERA, FIP, xFIP, and xERA. His fWAR (1.0) in 2023 has practically equaled his 2022 whole (1.1) in a single quarter as many begins.

That all sounds encouraging, however Berríos doesn’t have a excessive bar to clear. Calling his 2022 season forgettable could be beneficiant, contemplating he tied Germán Márquez for the major-league lead in earned runs allowed (100).

Berríos’ early-season positive factors have largely been on the modest aspect. His strikeouts are up from 2022, however should you throw away final season, they’re at their lowest level since 2017. His stroll charge is down by simply 0.3 p.c. His ERA (4.70) continues to be considerably above league common (4.31) and his xERA (4.87) isn’t far off final yr’s mark (5.11).

There is one space the place he’s made vital strides, although.

Berríos has completed a much better job of conserving the ball on the bottom than ever earlier than. Not solely is his groundball charge (51.1%) a lot increased than any he’s produced in any of his prior seasons, it’s a greater quantity than he’s ever had over an eight-start span.

The most evident clarification for these outcomes could be a change in pitch combine with an emphasis on pitches extra more likely to generate grounders, however Berríos is deploying his arsenal in an identical approach to 2022:

While the repertoire is essentially the identical, two of Berríos’ 4 pitches are producing grounders at a a lot increased charge than common: his changeup and sinker.

Both of these choices are inducing unfavourable launch angles on batted balls in opposition to them. That’s vital as Berríos has by no means had a pitch he’s thrown greater than 20 instances generate a unfavourable launch angle in a season earlier than 2023 — and he hasn’t had one under eight levels since 2016.

Overall, his common launch angle in opposition to (5.9 levels) is lower than half of his profession common (13.6):

The query of why hitters are immediately topping his changeup and sinker doesn’t have an apparent reply as neither pitch is shifting a lot in a different way than it has prior to now. His changeup can be positioned very equally this yr to the place it was positioned in 2022:

His sinker is a distinct story. Last season, he constantly positioned it on the armside, letting it run in to right-handed hitters and away from lefties:

This yr, he’s switched up his focus, hugging the glove aspect.

The heatmap above tells the story of a pitcher who’s staying out of the center of the zone extra — and the technique of jamming lefties and attempting to get right-handers reaching has resulted in loads of grounders. Berríos has a 69.5 per cent groundball charge together with his sinker, up from 47.5 per cent final yr.

What we’re taking a look at continues to be a comparatively refined change and the pattern measurement stays on the small aspect. That stated, if Berríos is ready to maintain his success inducing grounders going, that will likely be essential to his success placing collectively a bounce-back 2023.

The 28-year-old just isn’t putting out hitters at an elite charge, which is resulting in loads of batted-ball occasions. Surviving all of these balls in play could be tough if you enable loads of laborious contact — an outline that applies to Berríos, contemplating his xwOBA on contact (.419) is just like what he produced final yr (.405).

Nothing in Berríos’ observe file suggests he’s about to begin inducing gentle batted balls like Chris Bassitt or Alek Manoah final season. But if he can maximize the quantity of contact that comes on the bottom, it’ll assist him mitigate his issue stopping hard-hit balls. More particularly, it’ll maintain the ball within the park.

Last season, Berríos had the Seventeenth-highest HR/9 (1.52) among the many 140 pitchers with a workload of 100 innings or extra. This yr the right-hander’s HR/9 (0.98) is effectively under the league common (1.17). Very little of that enchancment is because of a superior capability to stop flyballs from clearing the wall.

Berríos’ HR/FB (12.2%) in 2023 is consistent with his profession common (12.4%) and just under final yr’s quantity (13.5%). Preventing flyballs from taking place within the first place is the important thing.

Last yr, Berríos proved he’s some of the tough gamers to venture by going from considered one of MLB’s most constant starters to one of many majors’ best pitchers to hit. With that in thoughts, it doesn’t appear sensible to make daring proclamations about what the remainder of his 2023 will appear like.

Even so, his early success inducing groundballs is intriguing. If he’s capable of stick with it, his 2023 season gained’t simply clear the low bar of being higher than the one which preceded it. It could possibly be a real bounce-back marketing campaign.
