September call-ups, both high-profile and totally innocuous, have been trickling in over the transaction wire for the last several days. As always, there are some that will have real impact on the playoff race, some that are interesting for the purposes of player evaluation, such your usual spare lefty reliever and catcher (by far the most common types of September additions), and some teams with no new names at all. Below I’ve compiled notes on every player brought up by National League teams since the start of the month, no matter how inconsequential, and I slip some rehabbers and August 31st acquisitions in here, too. It’s a primer for you to get (re)acquainted with players who might impact the playoff race or seasons to come.

Contenders’ Reinforcements

Atlanta Braves — INF Johan Camargo, RHP Chad Sobotka, RHP Jeremy Walker, LHP A.J. Minter, RHP Bryse Wilson

Camargo didn’t hit with the big club at all this year, not even in late July or all of August when he was handed pretty regular at-bats filling in for an injured Dansby Swanson. But he hit .483 over the few weeks he was down in Gwinnett after Swanson returned and Camargo was optioned. He’ll be a versatile, switch-hitting bench piece for the stretch run, and he projects as that sort of premium bench player long-term.

Sobotka and Walker were optioned to make room for the multiple relievers Atlanta acquired at the deadline. Sobotka, who sits 94-98 with life and has a plus, 2900-rpm slider, posted a 16-to-2 strikeout to walk ratio at Triple-A since being sent down. You may see him pitching big innings this month. Walker has been throwing 25-pitch, 2-inning outings with three days of rest in between. He may be on mop-up or long relief duty. Read the rest of this entry »

At the end of June 2017, observers could have seen Gavin Lux’s performance as a 19-year-old in the Midwest League and been underwhelmed. Despite a solid 11.1% walk rate and 18.7% strikeout rate, the 2016 first-round pick was hitting .211/.304/.303. The skepticism that often surrounds high school position players from northern states followed Lux through his amateur and early professional days, and the Kenosha, Wisconsin native did little to allay those concerns.

Meanwhile, believers took a glass-half-full view of his performance at that point. A cold-weather player who shows good plate discipline and bat-to-ball ability in full season ball is nothing to scoff at; a middle infielder with athleticism and feel to play has a high floor. And the makeup for which Lux was lauded was thought to be a potential developmental separator, as the shortstop continued to gain strength and make swing tweaks.

Fast forward to the present day, a bit more than two years later, and the Dodgers have called up the 21-year-old, who notched his first two major league hits in his debut on Monday. After recovering in the last two months of 2017 to hit .244/.331/.362 with 27 stolen bases in the Midwest League, Lux turned on the burners. In 2018, he torched the Cal League through 88 games, hitting .324/.396/.520 with 41 extra-base hits. He made a 28-game cameo in the Texas League that year as well and continued to rake, hitting .324/.408/.495. Read the rest of this entry »

The 2019 Arizona Fall League rosters were (mostly) announced today, and we’ve created a tab on THE BOARD where you can see all the prospects headed for extra reps in the desert. These are not comprehensive Fall League rosters — you can find those on the AFL team pages — but a compilation of names of players who are already on team pages on THE BOARD. The default view of the page has players hard-ranked through the 40+ FV tier. The 40s and below are then ordered by position, with pitchers in each tier listed from most likely to least likely to start. In the 40 FV tier, everyone south of Alex Lange is already a reliever.

Many participating players, especially pitchers, have yet to be announced. As applicable prospects are added to rosters in the coming weeks, I’ll add them to the Fall League tab and tweet an update from the FanGraphs Prospects Twitter account. Additionally, this tab will be live throughout the Fall League and subject to changes (new tool grades, updated scouting reports, new video, etc.) that will be relevant for this offseason’s team prospect lists. We plan on shutting down player/list updates around the time minor league playoffs are complete (which is very soon) until we begin to publish 2020 team-by-team prospect lists, but the Fall League tab will be an exception. If a player currently on the list looks appreciably different to me in the AFL, I’ll update their scouting record on that tab, and I may add players I think we’re light on as I see them. Again, updates will be posted on the FanGraphs Prospects Twitter account, and I’ll also compile those changes in a weekly rundown similar to those we ran on Fridays during the summer.

Anything you’d want to know about individual players in this year’s crop of Fall Leaguers can probably be found over on THE BOARD right now. Below are some roster highlights as well as my thoughts on who might fill out the roster ranks.

Glendale Desert Dogs
The White Sox have an unannounced outfield spot on the roster that I think may eventually be used on OF Micker Adolfo, who played rehab games in Arizona late in the summer. He’s on his way back from multiple elbow surgeries. Rehabbing double Achilles rupturee Jake Burger is age-appropriate for the Fall League, but GM Rick Hahn mentioned in July that Burger might go to instructs instead. Sox instructs runs from September 21 to October 5, so perhaps he’ll be a mid-AFL add if that goes well and they want to get him more at-bats, even just as a DH. Non-BOARD prospects to watch on this roster include Reds righties Diomar Lopez (potential reliever, up to 95) and Jordan Johnson, who briefly looked like a No. 4 or 5 starter type during his tenure with San Francisco, but has been hurt a lot since, as have Brewers lefties Nathan Kirby (Thoracic Outlet Syndrome) and Quintin Torres-Costa (Tommy John). Dodgers righty Marshall Kasowski has long posted strong strikeout rates, but the eyeball scouts think he’s on the 40-man fringe. Read the rest of this entry »

Eric Hosmer is a hard man to shift against. Though he fits the two main criteria for an overshift (namely: he’s left-handed and plays baseball), that’s where his list as an ideal candidate ends. If ever anyone was going to poke a groundball the opposite way, it would be Hosmer — his groundball rate is perennially among the league’s highest, and he hits a fair number of them to the opposite field. Teams generally agree — he’s faced a shift in fewer than half of his bases-empty plate appearances this year, and only 40.7% overall. Both place him in the bottom third of left-handed batters when it comes to the defensive alignment.

You don’t have to dig into his groundball numbers for long to work out why. The reasoning behind a shift is simple; hitters pull groundballs. League-wide, a whopping 55.5% of groundballs have been pulled, against only 12.1% hit the opposite way. The split is the same regardless of handedness, but first base is conveniently located on the lefty pull side of the field, which makes shifting a left-handed batter a high-percentage move.

For some reason, though, Hosmer doesn’t fit that mold. In 2019, he’s pulled only 46.4% of his groundballs, almost exactly equivalent to his career average of 46.3%. He’s at 16.3% opposite-field groundballs for his career over a whopping 2,263 grounders. His pull rate is in the bottom 20% of batters this year, and was in the bottom 3% last year, the bottom 10% two years ago, the bottom 15% for his career — you get the idea.

This isn’t to say there’s no merit to shifting against Hosmer — you’d need a more detailed mapping of infielder speeds and groundball exit velocity to work the math out perfectly. But look at his groundball (and blooper) distribution from 2016 to 2019 and tell me you want to shift against this:

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 — JT Chargois, Brad Keller, and Adam Ottavino — on how they learned and developed their sliders.

———

JT Chargois, Los Angeles Dodgers

“I was having trouble getting one to spin — to turn over — so my high school coach showed me a spike. Over the years I’ve manipulated where I hold my [pointer finger] on the ball, but it’s still a spiked-curveball grip. I just throw it like a heater. Instead of getting out front and pulling it like a curveball, I stay true on it as though it was a heater.

“When I get in trouble — maybe it’s backing up on me — and I need to make an adjustment, I tend to change my mindset to more of a curveball, to more of a downer-pitch. I want it to have two planes, as opposed to just moving horizontally.

“It was actually taught to me as a curveball. Then I started throwing harder as I got older. I got stronger and was literally trying to throw the crap out of it. That’s kind of how it migrated into a slider. As opposed to having more of a wrist-turn to get a bigger break, [a slider] is more about the manipulation of your hand position at release point.

The Los Angeles Dodgers, at one point, had a weakness. Not a glaring one, and not one that was going to single-handedly derail their World Series hopes, but a weakness nonetheless. As of July 26, their catchers had combined for a ghastly 69 wRC+. Even considering the skid catcher offense has experienced in recent seasons, that’s a bad number, ranking 24th in baseball at the time. Because they were worth the sixth-best defensive rating in baseball, they sat firmly in the middle of the pack at 1.1 WAR. But their performance still represented a hole in a lineup that was otherwise loaded. The Dodgers could have attempted to trade for a catcher, but the market lacked an obvious J.T. Realmuto-esque candidate, with James McCann standing as seemingly the best option. Instead, the Dodgers promoted Will Smith from Triple-A. Smith, 24, had played in just nine big league games before being called up. A month later, he might be the best offensive catcher in baseball.

That sounds jarring until you look at his numbers. In 102 plate appearances, Smith is hitting .318/.392/.818 with 12 homers and a 197 wRC+. In just 28 games, he already leads all catchers in offensive runs above average (Off). That is a counting stat.

In a fraction of the time any other catcher has had in the majors, Smith has surpassed the field in total offensive production. The catcher position is notoriously shallow in terms of hitting talent across the majors, but the best of the bunch is still an impressive group. Sánchez is a barrels machine, Realmuto is the best overall catcher in the game, and Yasmani Grandal and Willson Contreras are both incredibly talented players. And yet, Smith has generated more value at the plate than any of them, in nowhere near their number of plate appearances.

That production has boosted a Dodgers lineup that almost certainly could have survived without the added help, but has gotten it anyway. The team entered the 2019 season with veterans Austin Barnes and Russell Martin plugged into the catching position. Barnes, 29, had a breakout season in 2017 when he put together a 142 wRC+ in 102 games while playing excellent defense, but his offense cratered in 2018 when he produced just a 78 wRC+. Martin, meanwhile, was acquired from Toronto in the offseason before playing the last year of a 5-year, $82-million contract he signed after the 2014 season. This season, both Barnes and Martin have experienced career-worst seasons at the plate, paving the way for the organization to promote Smith, who ranked as the 80th-best prospect in baseball on Eric Longenhagen and Kiley McDaniel’s preseason Top 100 list. In less than a month, Smith has rocketed Los Angeles from 24th to 10th in catcher wRC+, and from 15th to 8th in catcher WAR.

Smith, of course, could always hit some. A first round selection (No. 32 overall) by the Dodgers out of Louisville in 2016, he did modestly well at the plate over his first two seasons of pro ball, largely boosted by good walk rates of well over 10%. He showed power for the first time in a 72-game stint with Rancho Cucamonga in the hitter-friendly California League in 2017, boosting his ISO from .103 in the previous season to .216. He continued to add power at the Double-A level in 2018, again raising his ISO to .268 while maintaining a steady walk rate over 11%, but he struggled mightily after a promotion to Triple-A, finishing 25 games with a wRC+ of 8.

He was called up for the first time on May 28, though only briefly. He played six games over the next week or so, and hit a pair of homers while slashing .286/.348/619. His first career home run was a walk-off against the Phillies.

He was sent back to the minors with an OPS of .967. It hasn’t been that low since. He came back to the majors for three games at the end of the month and homered again, this time in a pinch hit spot. It was another walk-off.

Smith went on the injured list because of an oblique on June 26, and remained in Triple-A Oklahoma City until the Dodgers brought him back in late July; if his play is any indication, it seems unlikely he’ll return to the minors anytime soon. In Smith’s first game back in the majors on July 27, he went 3-for-3 with a homer and two doubles, driving in six runs. He hasn’t slowed down since then, hitting safely in 16 of the 19 games he’s played since his last call-up, with a total of 16 extra-base hits. His .548 ISO in that span is first in the majors, while his 216 wRC+ is third and his 1.5 WAR is seventh.

You might skeptical of how sustainable his numbers are, and after just 28 games, you’d be right to be. Smith likely isn’t a true talent 197 wRC+ hitter, nor is he going to keep up a nearly 12-WAR pace over a full season. But there’s evidence to support the notion that he’s a top-tier catcher bat. With 64 batted ball events under his belt, his barrel rate is 9.8%. For reference, Peter Alonso’s barrel rate is 9.9%, and those rates tend to stabilize faster than others. He also has an xSLG of .558 — well below his absurd current figure, but still an indication that his power numbers aren’t a total mirage, even if his average home run distance of 396 feet doesn’t quite match up with the very best of the best.

It’s great news for the Dodgers that they have a sweet-swinging catcher on their roster now, but does that mean he’s a step below the others on defense? Not necessarily. In 28 games behind the plate, he’s accumulated 3.0 defensive runs saved. That doesn’t place much of a gap between him and Barnes (9.5 defensive runs saved in 70 games) or Martin (7.6 in 68 games). He hasn’t played nearly enough games for his defensive metrics to stabilize enough to be trustworthy, but the fact that the early returns seem to be so positive can only be a good sign for his presence behind the plate.

Smith is likely going to regress, be it in the next couple of weeks or sometime next year. Fortunately, there’s so much space between his offensive numbers and the rest of the catching field that it will take a bit for the pack to catch up with him. He had solid hitting pedigree as a prospect, but I don’t know that anyone could have expected this. The juiced ball can take some shine off of any great power tear we’ve seen this season, rookie or not. But it isn’t as though every other backstop isn’t getting to swing at the same ball. Smith just happens to be hitting it better than anyone else. He’s the best hitting catcher in baseball right now. Finally, the hard-luck Dodgers get a break.

Aaron Bates has a dual role with the Dodgers. The 35-year-old former first baseman serves as the team’s assistant hitting coach, and he’s also the director of hitting for the minor leagues. Now in his fifth year with Los Angeles, he works in conjunction with big-league hitting coach Robert Van Scoyoc, and hitting strategist Brant Brown.

A third-round pick out of North Carolina State by Boston in 2006, Bates played eight professional seasons — he logged 12 plate appearances with the Red Sox in 2009 — before joining the coaching ranks. His final swings came with the Dodgers in 2014, the same year he was asked to help tutor up-and-coming prospects such as Scott Schebler and Corey Seager. From there he served as a hitting coach in the Arizona, Midwest, and California leagues. In 2018, he became the assistant hitting coordinator for LA’s minor league system.

Bates sat down to talk hitting when the Dodgers visited Fenway Park in mid-July.

David Laurila: How are hitters in the Dodgers’ system taught, and evaluated?

Aaron Bates: “Brownie and Robert are both unbelievable. They have a way of communicating with players that is simplistic, makes sense, and provides answers. They can say, ‘This is why you’re making outs,” or ‘This is why you’re doing that.’ When you can provides answers to a player, it’s a breath of fresh air for him.

“It’s extremely important to be upfront with the players. We let them know there are numbers we value, as far as them being promoted, and they’re not necessary your baseball-card numbers. It could be OPS, wRC+, and their walk and strikeout rates. We let them know it’s not solely based on their batting averages.

“We let them know what we consider a good at-bat. We’re process-oriented, so if you line out, don’t get mad, and if you get a bloop single, don’t get extra happy. Over the course of the season, what we want is for them to hit the ball hard. That, and to be process-oriented. Read the rest of this entry »

Jack Little may well become a big-league pitcher. Ditto a member of a big-league front office. Drafted in the fifth round this year out of Stanford University, the 21-year-old right-hander possesses the potential to do both. For now, he’s taking the mound for the Great Lakes Loons, the low-A affiliate of the Los Angeles Dodgers.

On Friday, I asked Little about the genesis of his low-three-quarter arm slot.

“That’s a good question, honestly,” replied the righty, who has a 2.05 ERA in 22 professional innings. “In high school I was more high three-quarters — a normal three-quarters slot — but then I kind of just naturally moved lower. It wasn’t intentional, I just did it.”

Success followed. Little began getting more swings-and-misses with his fastball, and unlike many pitchers who move to a lower slot, the movement wasn’t downward. “I started missing above barrels a lot more,” Little explained. “I became more deceptive, and while I’m not 98 [mph] — I’m only low 90s — it kind of gets on the hitter, and plays more up in the zone.”

His slider is his best secondary pitch, which didn’t used to be the case. Prior to moving into the closer role at Stanford in his sophomore season, Little’s changeup was his go-to off-speed. He subsequently became fastball-heavy, with his changeup in his back pocket, and his slider a reasonably reliable No. 2 option… this despite its being, as he now knows, markedly unrefined.

We have a sizable collection of players to talk about this week because the two of us have been busy wrapping up our summer looks at the 2020 Draft class over the last couple weeks. This equates to every prospect added to or moved on THE BOARD since the Trade Deadline.

Top 100 Changes
We had two players enter the 50 FV tier in Diamondbacks SS Geraldo Perdomo and Padres C Luis Campusano. Perdomo is in the “Advanced Baseball Skills” player bucket with players like Vidal Brujan, Brayan Rocchio and Xavier Edwards. He’s added visible power since first arriving in the States and had as many walks as strikeouts at Low-A before he was promoted to the Cal League, which has been Campusano’s stomping ground all summer. He’s still not a great catcher but he does have an impact arm, big power, and he’s a good enough athlete that we’re optimistic he’ll both catch and make the necessary adjustments to get to his power in games down the line.

We also moved a D-back and a Padre down in RHP Taylor Widener and 1B Tirso Ornelas. Widener has been very homer prone at Triple-A a year after leading the minors in K’s. His fastball has natural cut rather than ride and while we still like him as a rotation piece, there’s a chance he continues to be very susceptible to the long ball. Ornelas has dealt with injury and swing issues.

On Aristides Aquino
Aristides Aquino was a 50 FV on the 2017 Reds list; at the time, he was a traditional right field profile with big power undermined by the strikeout issues that would eventually cause his performance to tank so badly that he became a minor league free agent. A swing change visually similar to the one Justin Turner made before his breakout (Reds hitting coach Turner Ward comes from the Dodgers) is evident here, so we’re cautiously optimistic Aquino will be a productive role player, but we don’t think he’ll keep up a star’s pace.

Last Saturday night against the Padres in Los Angeles, five days past his 25th birthday, Walker Buehler authored the most dominant start of his young career. With a fastball that touched 99 mph and a slider and cutter that continually befuddled hitters, the Dodgers righty faced 31 batters, struck out 15 of them, walked none, and yielded just five hits. Only one of those hits was of consequence, namely Manuel Margot’s eighth-inning pinch-homer, which kept Buehler from throwing a complete-game shutout; he and the Dodgers had to settle for a 4-1 win. Even allowing for the fact that the Padres own the majors’ highest strikeout rate (26.0%) and weren’t fielding a modern day Murderer’s Row, Buehler’s performance was a thing to behold.

So, behold!

While the major league strikeout rate is again at an all-time high (22.8%), Buehler’s start was just the sixth of the season in which a pitcher struck out 15 batters. He’s the only pitcher with multiple 15-K games, as he whiffed 16 but allowed two solo homers (from among just three hits) against the Rockies on June 21; he didn’t need more than 111 pitches in either start. Here’s the complete set: Read the rest of this entry »
