Fernando Tatís Jr is arguably the most-exciting young player in the game. He’s certainly gotten off to a rousing start. Through his first 55 games with the San Diego Padres, the 20-year-old shortstop is slashing .327/.393/.620, with 14 home runs, a 162 wRC+, and 13 stolen bases. Twice he’s scored on a sacrifice fly that was caught by the second baseman. Defensively, his range and his arm have both elicited oohs and aahs from what is becoming an increasingly-invigorated Padres fanbase.

The conversation that follows is focused entirely on the young man’s approach to hitting. He’s learned his lessons well — primarily from his father, former big-league infielder Fernando Tatis — but at the same time, his M.O. at the plate is straightforward. Tatis likes to keep things simple, and that’s unlikely to change anytime soon. Given the numbers he’s been putting up, why should it?

David Laurila: Is hitting simple, or is it complicated?

Fernando Tatis: “It’s complicated if you want it to be. I think if you take it as simple as possible, you can be more consistent every day. People make it complicated when they start doing a lot of stuff — when you start doing a lot of stuff to your mind; when you think you’re doing this, you’re doing that. For me, a big thing is to remember that I’m playing baseball. I’m just a kid playing in a park. Yes, I have to make adjustments sometimes, but as simple as I can be at the plate is way better.”

Laurila: Are you basically hunting fastballs?

Tatis: “I’m always looking fastballs. I don’t want it to sound like hitting is that easy. Don’t get me wrong. Hitting is not easy. But again, as simple as I can make it is way better.”

Laurila: How do you go about recognizing breaking pitches? Is it mostly a matter of reps?

Tatis: “More reps will be better for you, but for me, recognizing breaking balls is … a big part is when you’re looking for his fastball, you forget about everything down. If you see spin up, those are the good ones to hit. The ones down are going to be hard.” Read the rest of this entry »

The past year has been a whirlwind for Liam Hendriks. A little over a year ago, he was designated for assignment by the Oakland Athletics. At that point in the 2018 season, he was sporting a 7.36 ERA with an ugly 6.43 FIP while also missing more than a month with a groin strain. No one claimed him on waivers and he was sent outright to Triple-A. He worked hard to regain his confidence while also honing his repertoire. He was recalled in September and pitched well enough as an opener to get the start in the Wild Card game against the Yankees. However, that game didn’t go to plan after an Aaron Judge two-run homer got the home team on the board early.

Even after all those setbacks, Hendriks has flourished as a critical piece in the A’s bullpen this year. He started the year in a familiar role, making a couple of opener starts and coming out of the pen as a middle reliever. But as the back-end of the Oakland bullpen began to struggle, Hendriks found his way into higher leverage situations. The climax of his year-long turnaround came when he was named to the American League All-Star team as a replacement for Charlie Morton.

Here’s how Hendriks stacks up against his fellow All-Star relievers and a few other top candidates.

Any of the other candidates listed above could have been chosen and no one would have batted an eye (ok, maybe not Ian Kennedy). But Hendriks leads the AL in WAR as well as park- and league-adjusted ERA. He’s been terrific, and the adjustments he’s made since last September are driving his newfound success.

Pitchers learn and develop different pitches, and they do so at varying stages of their lives. It might be a curveball in high school, a cutter in college, or a changeup in A-ball. Sometimes the addition or refinement is a natural progression — graduating from Pitching 101 to advanced course work — and often it’s a matter of necessity. In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.

In this installment of the series, we’ll hear from three pitchers — Pete Fairbanks, Jack Flaherty, and Will Smith — on how they learned and developed their sliders.

———

Pete Fairbanks, Texas Rangers

“My coach — this was in summer ball when I was 14 or 15 years old — was Matt Whiteside, who I believe pitched for the Rangers back in the day. He showed me a grip and said, ‘Hey, kind of just turn your wrist; turn it on the side when you throw it.’ It’s possible that it was originally taught to me as more of a curveball, but looking back it’s always had slider characteristics to it. Regardless, that was my introduction to a breaking ball.

Pete Fairbanks’ original slider grip.

“The grip was similar to the one I have now, although it has varied over time. My slider has been good and bad. For instance, it was really cutter-y in 2017; it was very flat. It had six-to-eight inches of lift to it, which obviously isn’t what you’re looking for from a slider. You’re trying to get closer to zero. But with the tweaks I’ve made to it this year, it’s really taken off.

“I worked with one of our systems guys, Sam Niedrorf, when I was down in High-A. He was the guy who was feeding me all of my numbers on it, so I could fiddle with it to get it where it needed to be this year. We had a portable TrackMan, and I threw a couple of bullpens in front of that. Read the rest of this entry »

Dakota Hudson is somewhat of a square peg in a round hole. At a time where four-seamers at the belt are de rigueur, the 24-year-old St. Louis Cardinals right-hander likes to live near the knees. Since debuting last season, Hudson has thrown his signature sinker a full 50% of the time. And he’s done so successfully. Hudson has a 3.31 ERA over 119-and-two-thirds career innings.

He hasn’t always relied on the worm-killer responsible for his MLB-best (among qualified pitchers) 60.3% ground-ball rate. As a young pitcher at Mississippi State University, Hudson was primarily four-seamers from straight over the top, and a breaking ball he couldn’t consistently command. Then came his metamorphosis.

“Butch Thompson was my pitching coach at the time,” explained Hudson. “I was 10 or 11 appearances into my sophomore year, and had just gotten through maybe two innings. He came up to me and said, ‘Hey, are you willing to make a change?’Of course I was. So I dropped down.”

The original plan was to drop all the way down to sidearm, but Hudson couldn’t comfortably get that low. He ultimately ended up closer to three-quarters, with a sinker and a cutter/slider becoming his weapons of choice.

The process of finding the most-optimal arm slot was achieved sans a catcher. Read the rest of this entry »

Lourdes Gurriel Jr. needed a reset. It was April 14, and he was hitting .175/.250/.275 over 44 plate appearances. After starting the season 2-for-27, he’d recorded hits in four straight starts, but the Toronto Blue Jays still saw enough significant problems to warrant time in the minor leagues. They sent him down to Buffalo, where he hit .276/.308/.480 with a 94 wRC+ in 31 games. It was a perfectly cromulent performance, but nothing that suggested he was a brand new man capable of wreaking havoc on big league pitching.

Then in his first game back in the majors on May 24, Gurriel hit his first homer of the season. The next day, he homered again, and the day after that, he homered again. He hit another three games later, was quiet for a week after, and then rattled off 10 homers in his next 18 games. That included back-to-back two-dinger performances last Wednesday and Friday. Since his return from the minors, no one in baseball has better numbers than Gurriel in homers (14), slugging percentage (.750), wOBA (.466), or wRC+ (199). Just three hitters have produced more WAR.

Gurriel’s hot streak is a surprise, though not because his talent has ever been in doubt. A native of Sancti Spiritus, Cuba, he was known in his young Havana Industriales career for being an athletic player with a nice glove, but he began to break out with the bat by hitting .344/.407/.560 in the 2015-16 season. That’s the kind of performance that will help put a player’s name on the map, but in Gurriel’s case, plenty of people already knew his name. His father, Lourdes Gourriel, is a former Cuban National Series MVP winner and won a gold medal with Team Cuba in the 1992 Olympics. Meanwhile, his older brother Yuli had already been a star in Cuba for the better part of a decade. Lourdes Gurriel Jr. definitely had strong baseball genes, and in November 2016, he signed a seven-year, $22-million contract with the Toronto Blue Jays, a team that has shown quite an affinity for signing players who come from prominent baseball families.

How would you adjust your pre-draft evaluation of a high school pitcher if you knew he couldn’t pass a physical? That is what teams needed to decide about White Sox righty Dylan Cease, who after a surgery, a year of rehab, and four years of development, will make his first big league start today.

Some version of this scenario occurs almost annually: High school pitcher throws hard during his showcase summer, becomes very famous, comes out the following spring throwing even harder, then breaks. In Cease’s case, he was 93-96 and touching 98 during showcases, then touching 100 early the following spring before he was shut down with an elbow injury that would, as teams knew ahead of the draft, eventually require surgery.

For some teams, the injury shut the door on Cease as an option entirely. He was a Vanderbilt commit whose long arm action some teams had already feared increased his risk of injury, or at least might impede his ability to develop command and a changeup, and funnel him toward a bullpen role.

But Cease also had among the 2014 draft’s best velocity and breaking ball combination. The Cubs properly assessed his signability, and after cutting an underslot deal with Kyle Schwarber for $1.5 million at pick No. 4, they suddenly had a bunch of extra bonus pool money to play with. They ended up signing three high school pitchers to overslot bonuses — Cease, Justin Steele and Carson Sands — and cutting underslot deals of varying amounts at every other pick in the first 10 rounds.

Cease signed for $1.5 million, which was the slot value of that draft’s 38th pick and is around where high school pitchers with this kind of stuff, albeit healthy ones, typically come off the board these days. It took a fortuitous intersection of several variables: Cease’s talent, the Cubs optimistic evaluation of it and his signability, the opportunity created by the underslot deal with Schwarber, and a level of comfort in taking an injured player aided by risk diversification in the other overslot high schoolers. The high school pitching crop in 2014 was wild, and a few of those players probably contributed to the current reticence to pick a similar guy very early. Read the rest of this entry »

Nathan Eovaldi hasn’t pitched in a major league game since April 17, and he won’t until sometime after the All-Star break, but this week, before even beginning a rehab assignment, he’s been cast as a potential solution for one of the Red Sox’s biggest weaknesses: their bullpen. On Tuesday, in the aftermath of the team’s drubbing by the Yankees in the two-game London Series — during which that bullpen was torched for 21 runs and 23 hits in 12.1 innings — manager Alex Cora and president of baseball operations Dave Dombrowski announced plans to use Eovaldi as their closer, a job the 29-year-old righty has never held before.

Eovaldi, who is recovering from arthroscopic surgery to remove loose bodies in his right elbow, struggled with his command and control while making just four starts in April, getting hit to the tune of a 6.00 ERA and 7.12 FIP. That comes after last year’s strong rebound from his second Tommy John surgery, during which he threw 111 innings with a 3.81 ERA, 3.60 FIP, and 2.2 WAR. Integrating a relatively new cut fastball into his arsenal, he set career bests with a 22.2% strikeout rate and 4.4% walk rate. As Jeff Sullivan pointed out last November, his penchant for pounding the strike zone with such precision is rare among pitchers with such high velocity — and oh, can he bring it. According to Pitch Info, his average fastball velo of 97.4 was tied for third among all starters with at least 50 innings.

Eovaldi has rarely pitched out of the bullpen during his eight-year major league career, not only never notching a save in eight regular season relief appearances — four with the Dodgers as a rookie in 2011, three with the Yankees in an exile from the rotation in 2016, and one last year — but never even pitching in a save situation.

That said, he shined amid his crash course in high-leverage relief work last October, making four appearances during Boston’s championship run, two of them in save situations and one in extra innings. He threw 1.1 scoreless innings in front of Craig Kimbrel in the ALCS Game 5 clincher against the Astros, two days after making a strong six-inning start, then added scoreless innings in Games 1 and 2 of the World Series against the Dodgers, and pitched the final six innings of the 18-inning epic Game 3, taking the loss when he served up a solo homer to Max Muncy but winning the hearts of New England for his gutsy, 97-pitch effort. That was the only earned run he allowed in 9.1 relief innings; he yielded four hits and walked one while striking out seven.

Paul DeJong will represent the St. Louis Cardinals in next week’s All-Star Game. He’ll do so with solid, albeit unspectacular, offensive numbers. The 25-year-old shortstop is slashing .260/.344/.455, with 13 home runs and a 110 wRC+. Thanks in part to plus defense, he leads the Redbirds with 2.9 WAR.

Two years ago, in an interview that ran here at FanGraphs, DeJong discussed the mental side of hitting. This past weekend, the Illinois State University graduate — his degree is in biology — sat down for a far-wider-ranging conversation about his craft.

———

David Laurila: How would you describe your hitting approach?

Paul DeJong: “My general approach is to hit something hard through the middle. I’m usually looking for a fastball that I can hit gap-to-gap; not pull, not oppo, but kind of through the middle. That gives me the best chance of adjusting to different speeds and different locations. I’m able to open up, or if I’m late, I still have time to keep it fair.”

Laurila: Something I’ve been asking players about is the idea of an A-swing, and whether hitters have multiple swings.

DeJong: “Hitters absolutely have multiple swings. For instance, if you get fooled on a breaking ball, you’re kind of adjusting your body. But for me, it’s more about keeping my hands back. If you do that, you can drift forward with your body — you’ll be off balance out front — but if your hands are still back, you’re able to deliver the barrel, still put the ball in play hard.”

Laurila: What about on fastballs riding high in the zone? Read the rest of this entry »

I’m here today to tell you about a player who has been hitting the ball tremendously hard of late. That’s nothing new — it’s a common genre of FanGraphs article. You know the deal, because I’ve written plenty of them this year already. Josh Bell is great now, Pete Alonso only hits lasers, Niko Goodrum can apparently hit, etcetera. Inevitably, these stories catch players near a performance peak. That’s just the nature of the beast; when you look for noteworthy and exceptional performances to write about, there’s very likely some luck involved, even if the underlying statistics look good.

The ideal form of this type of article finds something that’s truly different about the player, something other than mere batted ball luck. Josh Bell’s simplified stance, for example, really is different. Even so, baseball is a game with a lot of inherent luck to it, and if you single someone out for doing tremendously well, there was probably some luck involved. Today, though, we’re going to subvert the genre. Today, let’s look at a player who is, per the trope, hitting the ball harder than ever and turning fly balls into home runs at the highest rate of his career. There’s a twist, though: Wil Myers is doing all that, but he’s also having his worst season in five years. That sounds like something worth writing about.

Myers has always had power. He’s had a 30 home run season and a 28 home run season despite playing in a home park that suppresses home runs. Despite that, 2019 is seeing the highest HR/FB% of his career. (All stats are through Tuesday’s action.) His exit velocity on line drives and fly balls is in the 97th percentile of hitters with 50 air balls this year, tied with teammate Franmil Reyes. He doesn’t fare quite as well in terms of barrels per ball hit in the air, as he’s been a bit inconsistent, but he’s still in the top 20% of baseball. There are no two ways about it; Wil Myers is hitting baseballs as hard as he ever has.

So, what have the offensive rewards of Myers’ bruising new power been? He’s batting .218/.314/.399, good for a 91 wRC+. His batting average is the lowest of his career, and his OBP and slugging percentage are higher only than his disastrous 2014 Rays campaign. That batting average is especially jarring when you consider that it’s not BABIP-driven; he’s batting .316 on balls in play, higher than his career average and significantly higher than his Depth Charts projections. High BABIP and low batting average? Strikeouts have to be the culprit here, and my goodness, Myers has struck out a lot this year — 35.6%, to be exact. Read the rest of this entry »

Last Thursday, after Edwin Díaz’s meltdown in Philadelphia — five runs allowed in 1/3 of an inning, including the game-tying and game-winning home runs — I tweeted about Díaz’s 2019 performance in comparison to his 2018 performance. I argued that Díaz wasn’t that much worse this year compared to last, citing his strikeout-to-walk numbers and his xFIP. In response, others felt that Díaz had experienced a significant drop-off, contending that an increase in hard contact allowed as well as a lower strikeout rate suggested a serious fall in performance.

This discussion is what prompted this post. My followers and I agreed on one main point: Díaz is worse this year. Where we disagreed is more complicated: Just how much worse is Díaz, and why?

First, it cannot be understated just how good Díaz was in 2018. In 73.1 innings with the Mariners, he posted a 1.96 ERA and a 1.61 FIP. His 38.2% K-BB rate was the highest among all relievers with at least 10 innings pitched, and his 3.5 WAR ranked second. Seattle sold high on Díaz, trading him (along with Robinson Cano) to the Mets in December in a seven-player deal. They received Justin Dunn and Jarred Kelenic, and while it’s far too early to declare a winner of this trade, the Mariners’ end looks quite strong so far.

This season, Díaz has been undeniably worse. As alluded to above, his strikeout rate has experienced a dip, but his K-BB rate still ranks eighth among the 174 qualified relievers through the end of June. This drop is probably not due solely to regression, but it’s still worth noting that Díaz has only fallen from the 99th to the 95th percentile in the statistic. He’s still elite in that regard. Of course, strikeouts and walks aren’t the only things that matter, but relievers have less of an opportunity (at least compared to starters) for batted ball luck to even out within one season. One bad outing, like Díaz’s against the Phillies, can influence their full season numbers pretty significantly. Díaz has allowed 17 earned runs this season (4.78 ERA). Twelve of them have come across just three outings. Read the rest of this entry »
