The Twins starting rotation is a clear area of weakness for the team as they head into the 2022 season. The departures of José Berríos, J.A. Happ, and Michael Pineda, plus Kenta Maeda’s elbow injury, drained the group of some serious talent. Before the lockout, Minnesota’s only move to address this concern was to add Dylan Bundy on a one-year deal. For all sorts of reasons, it seems clear the team just isn’t likely to bring in another quality starter from outside the organization. Instead, I suspect the Twins are hoping some of their young starters will take a significant step forward in 2022.

Bailey Ober, Joe Ryan, and Randy Dobnak have fewer than 50 career starts between them but each is likely to hold down a significant role this year. Earlier this week, I examined Ober’s deep arsenal and the path he could take toward a breakout sophomore season. Despite being injured for most of 2021, the five-year extension Dobnak signed before the season should give him a long leash to prove he can be a successful major league starter. Luke Hooper already investigated the intriguing addition of Jharel Cotton to the pitching staff (though his role is far from defined at this point). As for Ryan, he has a fascinating profile that has the potential to be the best of the bunch.

Ryan was a seventh round pick in the 2018 draft out of Cal State Stanislaus. He was assigned to Low-A that same year and started racking up tons of strikeouts. After blowing through three levels of the minors in 2019, he started appearing on Rays prospect lists, debuting at 13th on the 2020 list as a 45 FV. In all, he compiled a 36.7% career strikeout rate as a member of Tampa Bay’s farm system. Questions about his fastball, which sat around 90-94 mph, and a lack of quality secondary stuff held him back from rising any higher on our prospect lists despite the elite results he was putting up at each level.

Eventually, Ryan was traded to the Twins in the Nelson Cruz deal and made his major league debut on September 1. The strikeouts continued to come in the big leagues, as he sent down 30% of the batters he faced on strikes. He wound up with a 3.43 FIP and a phenomenal 6.00 strikeout-to-walk ratio across his five starts during the final month of the season. Read the rest of this entry »

A fact: Among the 157 pitchers with a minimum of 400 innings pitched since 2016, Dodgers southpaw Julio Urías has the lowest home run per fly ball rate (HR/FB) at 8.4%. The distance between him and second-place Brad Keller (10.1%) is the same as the distance between Keller and 20th-place Rich Hill (11.8%). It’s no wonder that Urías has been terrific so far in his career – he’s controlled the contact he allows like no other.

Also a fact: The reason why xFIP still holds up as a decent ERA estimator is because most pitchers, regardless of their talent level, tend to drift towards a league-average HR/FB rate. Yet here’s Urías, resisting the inevitable pull of regression before our very eyes. Does he have a secret? Or is he merely running from the grim reaper, time ticking with each step? I’m still not sure! But if you’ll allow, here are a few educated guesses that hopefully make sense.

First things first, I need to address a common possibility. As Jeff Zimmerman demonstrated years ago, pitchers with higher fly ball rates also have lower HR/FB rates. That’s because they also get their fair share of popups, so the denominator ends up outpacing the numerator. But even though Urías isn’t a groundball pitcher, he isn’t a notable fly ball pitcher, either. He’s 37th among the aforementioned 157 in terms of fly ball rate – above-average, sure, but not extreme enough to explain his deflated career HR/FB mark. Our answers, if any, lie elsewhere.

If you wanted to design a puzzle to attract my interest, you couldn’t do much better than pitchers who throw both sinkers and four-seamers. I love thinking about pitching. I love thinking about fastball spin, and I’ve been having a blast looking at approach angle recently. Want to kick it into overdrive, though? Add in platoon splits, and we’re really cooking with gas.

One of those weird, of-course-this-exists-but-we-don’t-talk-about-it splits is groundball pitchers against flyball hitters and vice versa. I first learned about this split in The Book, and while it’s always made sense, Alex Chamberlain put it into a pretty picture recently that brought it back to mind for me:

fly ball hitters perform better against ground ball pitchers, and ground ball hitters perform better against fly ball pitchers

There are some terms you might not know on there, like pitcher influence on launch angle. For that, you should read Alex’s work on launch angle here. Honestly, you should probably just read all of Alex’s stuff anyway – but particularly for this, his work is invaluable.

The key takeaway here? Against groundball hitters, sinkers are an excellent choice of pitch. The hitter tends to hit the ball into the ground and sinkers generally influence launch angles downward. The result is frequently a grounder, which is great for the defense. Similarly, if you’re facing a fly ball hitter, you want them to hit it even higher into the air, which means a four-seamer with solid rise is the ticket. Read the rest of this entry »

Ryan Vilade knows what he does best with a bat in his hands. He also knows what he needs to do better. The son of a longtime coach — James Vilade has tutored hitters at both the college and minor-league levels — the 22-year-old outfield prospect possesses a smooth right-handed stroke, albeit one that has propelled fewer balls over fences than his size would suggest. Since being selected 48th overall out of a Stillwater, Oklahoma high school in 2017, the 6-foot-2, 225 pound Vilade has gone yard just 29 times in 1,783 professional plate appearances.

But he can square up a baseball. Playing at Triple-A Albuquerque this past season — his first action above High-A — Vilade slashed a solid .284/.339/.410, earning himself a late-September cup of coffee in Colorado. Prior to the 2020 COVID shutdown, Vilade put up a .303/.367/.466 slash line for the California League’s Lancaster JetHawks.

Vilade — No. 3 in our newly-released Rockies Top Prospects list — discussed his hitting approach, and the adjustment that should lead to more dingers, late in the Arizona Fall League season.

David Laurila: To start, who are you as hitter? What do you do well?

Ryan Vilade: “If I had to give a scouting report on myself, I would say that I drive the ball the other way really well. That’s my strength. One thing that I continue to work on is pulling ball in the air. I can do that well with off-speed; it’s the fastball that I go [opposite field] with. That doesn’t really bother me, because I feel like pulling the fastball is something that you just react to. But yeah, staying the other way and reacting off-speed. That’s kind of who I am.”

Laurila: Why is your swing conducive to driving the ball the other way? Read the rest of this entry »

After more than a month of silence, talks between the league and the Players Association have finally heated up. Over the past week, the parties have exchanged proposals and counters, a welcome change from the negotiations’ previously slow pace; 42 days elapsed between the owners’ initiation of the lockout and their first proposal to the MLBPA. Yesterday, the two sides reportedly focused their discussion on players who have not yet qualified for salary arbitration, a key sticking point in the negotiations. Let’s go through each of those proposals and see what they would do to change the way young players get paid.

Before we begin, it’s worth mentioning that the two sides each recently dropped aspects of past proposals that the other disliked. The league had previously proposed changes to the arbitration system, including the elimination of the Super Two classification that allows some players to reach arbitration a year early, a non-starter with the union. The union had proposed an age-based free agency system that would shorten team control in many instances, which was similarly unpopular with the league. Each side dropped those long-shot ideas in this round of bargaining. Now, on to what was proposed yesterday.

First, both sides proposed instituting new salary minimums. The MLBPA suggested a new minimum salary of $775,000. The league countered with a tiered structure – $615,000 for players with less than one year of service time, $650,000 for players with between one and two years of time, and $700,000 for everyone else on a minimum salary.

“Players on a minimum salary” might not sound like a key part of the structure of baseball, but they absolutely are, as FanGraphs alum Travis Sawchik has covered. These players aren’t a huge part of the money, of course – “minimum” is a helpful word there. In 2021, teams spent roughly $3.842 billion on player salaries, per Spotrac. Minimum salaries accounted for roughly $289 million of that, or 7.5% of the total outlay. Read the rest of this entry »

After trading away José Berríos and J.A. Happ last season and losing Kenta Maeda and Michael Pineda to Tommy John surgery and free agency, respectively, the Twins rotation was in serious need of rejuvenation. Instead of diving into the pre-lockout free agent frenzy in November, the Twins stayed on the periphery, only signing Dylan Bundy to a one-year, bounce-back contract after his ugly season for the Angels. With Byron Buxton newly signed to a long-term extension, the Twins have indicated their intention to compete for the AL Central crown in 2022. But even with Bundy added to their staff, their starting rotation looks exceedingly thin.

Under president of baseball operations Derek Falvey and general manager Thad Levine, Minnesota has been notoriously risk averse when it comes to committing to pitchers for any significant length of time. It was probably a long shot to assume the Twins would be among the suitors for the top names in a strong class of free agent starting pitchers and once the lockout is lifted, it seems like it’ll be difficult to add another arm to their rotation. Of the 16 starters ranked in our top 50 free agents, all but six have already signed with a new team. That doesn’t leave many options for the Twins when it comes to outside help.

Instead of bringing in another quality arm from outside the organization, I suspect the Twins are hoping some of their young starters take a significant step forward in 2022. Bailey Ober, Joe Ryan, and Randy Dobnak have less than 50 career starts between them but each will likely hold down a significant role this year. Additionally, top pitching prospects Jordan Balazovic and Jhoan Duran could make their major league debuts some time during the season. It may not be an inspiring group of names, but one of those young pitchers holds potential that could provide some upside for Minnesota.

Among that group of inexperienced starters populating the Twins’ projected rotation, Ober compiled the most innings in 2021. He made his major league debut in mid-May and wound up throwing 92.1 innings with a 4.19 ERA and a 4.56 FIP that was just a step behind. Even more impressive was his 5.05 strikeout-to-walk ratio, the 13th highest in the majors among starters who threw at least 90 innings. Those excellent peripherals formed the foundation of his 4.01 xFIP, with only his extremely high home run rate holding him back.

A 12th round pick in the 2017 draft, Ober compiled a 31.9% strikeout rate during his minor league career. He paired that lethal ability with a 3.4% walk rate; astonishingly, his walk totals never crossed double-digits in any of his minor league stops. With such phenomenal results, you might expect Ober to be highly ranked on the Twins prospect lists, but he never reached higher than 22nd on the 2021 list with a 40 FV. His command was an obvious strength but his fastball consistently sat below 90 mph in the minors. There was some considerable dissonance between his scouting reports and the results he was putting up.

During the 2020 season, Ober wasn’t invited to the alternate site but worked on smoothing out his mechanics on his own. Upon reaching the majors in May 2021, his fastball averaged 92.3 mph, a big uptick in velocity. The raw velocity he showed in the big leagues was a significant improvement over what he was showing in the minors, but 92 mph isn’t exactly head-turning. Fortunately, his gigantic 6-foot-9 frame allows him to impart a ton of additional effective velocity on his pitches. Just six other pitchers had a higher release extension than Ober’s 7.3 inches. That elite extension helped him add more than 2 mph to his heater, the largest difference between raw velocity and effective velocity among all fastballs thrown at least 100 times in 2021.

With a heater that plays up due to his extension and uncommon delivery, he leaned on that pitch pretty heavily during his rookie season. His excellent command allowed him to locate his fastball up in the zone regularly. The combination of effective velocity and location led to a 24.8% whiff rate, slightly above the league average for four-seamers. Even though batters often had trouble making contact with the pitch, they did tremendous damage against it when they did put it in play. Throwing hard stuff up in the zone comes with its drawbacks if batters are able to connect with those pitches. Nearly 60% of the balls in play off Ober’s fastball were fly balls or line drives and he allowed a .578 expected wOBA on those elevated batted balls.

Ober’s repertoire also includes a slider, changeup, and curveball. Of those three secondary pitches, the two breaking balls are the most interesting. Along with his fastball, those three pitches each ran swinging strike rates in the double digits, forming a deep arsenal to give Ober plenty of options with which to attack batters. What’s more, he completely revamped his slider mid-season. In an effort to differentiate his slider from his curveball a little more, he tinkered with a new slider grip and started implementing it in mid-August. He detailed his process in an interview with David Laurila in September:

I started throwing a new slider [in early-to-mid-August]. I wanted something a little bit harder. It had been around 78-80 [mph] and I wanted to give hitters something different. It was kind of blending with my curveball, too. Basically, the idea was something with a bigger speed difference between my curveball and my slider.

Before, I had it a little deeper in my hand and it had a lot more horizontal movement on it. It wasn’t as depth-y as my new one. My new one is harder [82-84] and has a little more depth, and it’s also not as horizontal anymore.

Here’s how different his two sliders looked in practice. This slider was thrown in mid-July:

And here’s his overhauled slider from a game in mid-August:

They’re completely different pitches. Ober still used them both similarly, locating them on the outer edge against right-handed batters to generate swings and misses. Here’s what the physical characteristics and results of the two pitches looked like:

Despite the drastic changes to the pitch’s shape, his results were nearly the same as they were with the slower, looping slider. But with his harder slider established in his repertoire, his curveball suddenly became vastly more effective. From August 11 through the end of the season, Ober’s curveball ran a 45.5% whiff rate, a 26.5 point improvement over the 19% whiff rate he ran during the first half of the season. Differentiating the two pitches really helped him mold his breaking balls into two separate weapons that should give batters fits at the plate.

The path towards a breakout season for Ober seems pretty clear. He has three pitches that produce excellent results and he has excellent command of his entire arsenal. His fastball is decent, especially with its effective velocity helping it play up, but he could probably stand to throw it a bit less in favor of his two breaking balls. Pounding the strike zone with his heater is a fine strategy in the minor leagues, but he needs to learn how to better incorporate his two breaking balls into his pitch mix to avoid allowing so much loud contact off his elevated fastballs. I haven’t even mentioned his changeup, which was graded his best secondary offering as a prospect. With such a deep repertoire, Ober has plenty of avenues to take to build on his promising debut.

Josh Jung is the top position player prospect in the Texas Rangers system. He’s also a bona fide hitting nerd. A 23-year-old third baseman who was drafted eighth overall in 2019 out of Texas Tech University, Jung not only embraces analytics, he’s reconfigured his swing and his approach since inking a contract. The results speak for themselves. Splitting his first full professional season between Double-A Round Rock and Triple-A Frisco, Jung slashed .326/.398/.592 with 19 home runs in just 342 plate appearances. His best-in-the-organization wRC+ was a lusty 152.

Jung discussed his data-driven development, which comes with a “train dirty to play clean” mindset, last week over the phone.

———

David Laurila: Let’s start with one of my favorite openers: Do you view hitting as more of an art, or as more of a science?

Josh Jung: “It’s both. Trying to be consistent is the art part. When you break it down and go analytical is the science part of it.”

Laurila: Which way would you lean if forced to choose one or the other?

Jung: [Long pause] “Maybe more of an art. Hitting is one of the hardest things to do in the world of sports. If you’re successful three out of 10 times you’re viewed as good, and that doesn’t happen in any other sport, or with any other metric. So I’d have to say it’s pretty much an art.”

Laurila: How would you describe your art? Read the rest of this entry »

Last Friday, I suggested a change to line scores that I think would go a long way towards updating them for the modern era. I’ve spent quite a bit of time thinking about the broad strokes of the change – how errors and hits are no longer the most useful two data points, and how extra-base hits can tell you a lot about how a game felt.

One thing I couldn’t do before last Friday: get thousands of passionate baseball fans to read my idea and suggest changes. I still like my idea – one-base hits and extra-base hits instead of hits and errors – but I liked tons of the suggestions that I received in the comments as well. Rather than rule by fiat, I thought it would be interesting to poll the same people who came up with all these great ideas on which one they like best.

To demonstrate each of the possible scoring solutions, I’m going to use the contest between the Astros and A’s that led off last Friday’s column. As a reminder, here’s the line score rendered in the current style (courtesy of Baseball Reference):

I have a problem. I can’t stop writing about how good Luke Weaver can be, even as he continues to be just okay. Don’t believe me? The first article I ever wrote was titled “Why is Luke Weaver so Effective?” When he started strong in the 2019 season, I was back on the same nonsense again, this time with “Luke Weaver, Retooled and Reimagined.”

As soon as I wrote that, he strained his forearm and barely pitched again that year. He came back in 2020 and 2021 and scuffled – he managed a 4.53 FIP (4.61 xFIP) in 117.2 innings, but a low strand rate as part of a brutal 2020 led to an aggregate 5.28 ERA. And here I am again, writing about how Weaver can excel in 2022.

Why do I keep doing it? Because I keep believing it! I can tell you truthfully that I think he has the tools to be a second or third starter, even though he’s been more like a fourth or fifth option so far in his career. You might wonder how that’s the case – after all, he’s basically a two-pitch pitcher, he doesn’t throw particularly hard, and his changeup, easily his best pitch, got tattooed in ‘21. I’m here to tell you: you just have to believe.

Is throwing a four-seam fastball down the middle a good idea? Regardless of whom you ask, the answer is probably no, and for good reason – the heart of the zone is where the majority of hard contact occurs, and fastballs are the most contact-prone of any pitch type. This disdain is rooted in our baseball lexicon, too. You’ll notice that after a ball is hit out of the park, broadcasters tend to remark that the pitcher “left one over the middle” or “hung his fastball.” The location is often to blame.

That doesn’t stop pitchers from trying, though. That’s not always because they want to – command comes and goes, after all – but it’s also because hitting a baseball is extremely difficult. Swings and misses happen! Bad contact happens! In each season since 2015, when Statcast data became public, hitters have accumulated a negative run value against down-the-middle fastballs. They’re still in the red despite seeing easier pitches. Though no pitcher would want to live solely in the middle, it makes sense why one might venture there.

But 2021 brought changes to the majors, and this is one of them: Hitters did worse against so-called meatballs than ever before. Here’s a graph that shows the league’s run value per 100 against fastballs in Baseball Savant’s “Heart” zone. Again, 2015 is the starting point:
