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 »

Every year, hapless hitters with premium arm strength get moved to minor league mounds. With the help of Sean Dolinar, who combed the last few years of stats to scrounge up a more comprehensive list of converts than I was otherwise able to remember off the top of my head, I assembled the list below of former position players who are now prospects of note as hurlers. This is not a comprehensive survey of every recent conversion arm in the minors. Instead, these are the pitchers I think are interesting enough to include on an offseason list in some capacity.

Conversion arms who pan out typically put it together quickly. For example, it only took Kenley Jansen about a year after he first toed an affiliate’s rubber to reach Dodger Stadium. He likely threw during 2009 Extended Spring Training, then spent the back half of the summer at Hi-A before making a Fall League appearance. He breezed through Hi- and Double-A the following year, and was in Los Angeles by late July of 2010. Jason Motte started his conversion in 2006 and got his first big league cup of coffee in September of 2008. Joe Nathan’s first pro innings came in 1997; he was first called up to the majors early in 1999. Sean Doolittle threw just 26 minor league innings before the A’s brought him up. (Conversely, Alexi Ogando and Carlos Marmol each took about three years after moving moundward to become big leaguers.)

Who in the minors might be next to have impact, big or small, on a big league pitching staff? Here are some candidates. All of the 35+ FV and above players are now on THE BOARD, if they weren’t already.

When A.J. Puk debuts today — and even though he has been in the bullpen since late-June, he is likely to pitch this evening against the Yankees — he’ll be the 51st player from the 2016 draft to play in the big leagues. He does so, despite missing more than a year recovering from Tommy John surgery, before every high school pitcher selected in 2016, other than Dustin May. Among 2016 draftee prospects still eligible to be on THE BOARD, Puk is ranked sixth; were I to include graduated players from that draft, he’d be seventh. Nick Senzel would slot ahead of him, but I’d still take the next half decade of Puk ahead of Pete Alonso, who I worry will have an early, precipitous decline phase. Read the rest of this entry »

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.

The 2019 trade deadline has passed and, with it, dozens of prospects have begun a new journey toward the major leagues with a different organization. We have all of the prospects who have been traded since the Nick Solak/Peter Fairbanks deal ranked below, with brief scouting snippets for each of them. Most of the deals these prospects were a part of were analyzed at length on this site. Those pieces can be found here, or by clicking the hyperlink in the “From” column below. We’ve moved all of the players below to their new orgs over on THE BOARD, so you can see where they rank among their new teammates; our farm rankings, which now update live, also reflect these changes, so you can see where teams’ systems stack up post-deadline. Thanks to the scouts, analysts, and executives who helped us compile notes on players we didn’t know about.

The A’s, who have about a 25% chance of pulling down a Wild Card spot and still haven’t won a World Series title for Billy Beane, continued their efforts to shore up a beleaguered rotation by acquiring Tanner Roark from the Reds Wednesday afternoon in exchange for High-A outfielder Jameson Hannah. Roark, 32, will join Homer Bailey as a newcomer to the Oakland rotation and will work to build on what has been a solid if uninspiring season for Cincinnati thus far.

Luckily for Roark, solid but uninspiring will work just fine for the A’s. Oakland’s bullpen has been top-five in the game by FIP (4.03), and its offense top 10 by wRC+ (102), but the rotation — missing Sean Manea, Marco Estrada, and Frankie Montas to injury or suspension — has stumbled to a 4.60 FIP that ranks 14th league-wide. 12 pitchers have made starts for the A’s this year, and seven of them have season FIPs above that 4.60 average. Roark’s 4.20 will, presumably, help.

So too will his durability. Roark has made at least 30 starts in each of the last three years and in four of the last five. Since 2016, only six starters have taken the mound more often, and only nine have thrown more innings. There could be no neater fit than the one between the team that needs reliable innings and a starter who can provide those innings at a modest price. Roark will be a free agent at season’s end, meaning that his acquisition changes Oakland’s future plans not one iota, and as Susan Slusser reports that the Reds will pick up $2.1 million of the remaining $3 million or so of Roark’s salary, the financial downside here is minimal to the point of absence.

Teams have been smiling at each another and making their fair share of prolonged eye contact, but the trade deadline tension had yielded little in the way of actual consummation until Saturday’s A’s and Royals trade that sent veteran lefty reliever Jake Diekman to Oakland for two prospects. Here’s the deal:

Oakland gets:

LHP Jake Diekman

Kansas City gets:

RHP Ismael Aquino
CF Dairon Blanco

Diekman, who has struck out 33.5% of opposing hitters and has a 3.37 FIP across 41.2 innings this year, immediately becomes the best lefty in Oakland’s bullpen, surpassing cutter/curveball/command lefty Ryan Buchter (who was also acquired from Kansas City via trade last year), and strike-throwing Taiwanese depth piece, Wei-Chung Wang. That’s less a knock on either of those two, and more to do with Diekman, who has been good with uncommon consistency for a reliever throughout his seven-year big league career.

On this date one year ago, the baseball season was in the midst of its brief halt for the All-Star Game in Washington, D.C. For the Oakland Athletics, it felt as if the season was just getting started. Through the end of May, the team had merely been average, at least by the most traditional statistic: win-loss record. On May 31, the A’s were 29-28. But a 68-37 record (a 105-win pace) over their final 105 games turned a decent season into an excellent one. The A’s finished 97-65, the franchise’s best record since 2002, en route to capturing the second AL Wild Card spot.

In 2019, the Athletics are writing the script to a sequel. On May 31, the team was again 29-28, but since that time, their 26-13 record is the second-best in the American League and the fourth-best in baseball overall. During this stretch, their pitching has been remarkable:

Homer Bailey woke up Sunday morning expecting to start a game between two teams going nowhere, but instead discovered that he would be joining a playoff chase. Kansas City shipped the righty to the Oakland A’s in exchange for 23-year-old shortstop Kevin Merrell.

Bailey, 33, has been a cromulent arm for KC this season, with a 4.80 ERA and 4.47 FIP in 90 innings. His 1.1 WAR is his best figure since 2014, while his 8.10 K/9 is his best mark since 2013.

Merrell, the 33rd overall pick back in 2017, ranked 20th on Eric and Kiley’s list of Oakland’s top farmhands before the season. Speed is Merrell’s calling card, but his 80-grade wheels haven’t had much chance to shine this year in Double-A, as he’s sporting a meager .246/.292/.339 line in 82 games.

Oakland will be Bailey’s fourth organization in the last eight months. After a 12-year stint with the Reds, he was shipped to the Dodgers in a seven-player swap that sent Yasiel Puig, Matt Kemp, Alex Wood and Kyle Farmer to Cincinnati in return for prospects Jeter Downs and Josiah Gray. Bailey’s inclusion in the deal was motivated entirely by finances, however, as the $22.45 million he was owed in 2019 was a close match with the $21.75 million owed to Kemp; the structure of Bailey’s contract made it more luxury tax-friendly to the Dodgers. One day after the trade was completed, Bailey was released by Los Angeles, and in February, he signed a minor league contract with the Royals.

While he rarely lived up to his billing as a top prospect, Bailey was a pretty good starter early in the decade, when he accrued 6.3 WAR from 2012-13 while throwing more than 200 innings each year. The Reds rewarded Bailey, then 27, with a six-year, $105 million contract extension. Twenty-three starts into what appeared to be another good season in 2014, he was shut down with an arm injury. He underwent Tommy John surgery, made just a combined eight starts from 2015-16, and in parts of four seasons following his injury, held a 6.25 ERA and 5.13 FIP in 231.2 innings.

It isn’t difficult to see why two playoff aspirants didn’t have room for Bailey. Just seven months later, however, another win-now team was willing to part with a top-20 prospect to add him to their rotation. What changed?

Well, for one, it’s always been somewhat difficult to differentiate between Good Bailey and Bad Bailey. His average fastball velocity in 2012 was 93.2 mph. In 2018, it was 93.0 mph. His chase rate in 2013 was 34.5%. In 2018, it was 33.0%. His swinging strike rate, pitch usage, and ground ball rates were consistent as well. And yet he’d gone from a solid No. 2 starter to nearly unemployed.

Bailey’s numbers in many of those areas haven’t changed much this season, either. His average four-seamer is 92.8 mph. His chase rate is just a couple ticks lower than last season. His groundball rate is up three points, and his swinging strike rate has climbed modestly as well.

There is, however, one big difference in Bailey’s repertoire. His career fastball percentage sits around 60%. In years after his surgery, it was 55%. This year, it’s down to 49.3%. His slider percentage, 17% a year ago, is down more than four points. Those missing fastballs and sliders have turned into splitters:

Bailey’s thrown his splitter on 27.3% of his offerings in 2019, more than eight points higher than any other season of his career. It’s a great pitch for him to lean on: According to Statcast, opponents have just a .195 xBA .250 xSLG against the split, and their actual numbers aren’t exceeding those estimates by much. Of the five pitches Bailey has used in 2019, three of them have an xwOBA above .350. Finding a pitch as reliable as the splitter has been vital for him, and as he’s thrown it more, he’s been more effective. In his last five starts, he’s thrown 29 innings and posted a 2.48 ERA.

That was good enough for Oakland to add him to its starting rotation. The A’s have weathered Frankie Montas’ suspension well, but they still need rotation help. Montas had a 2.70 ERA and 2.9 WAR in 90 innings before receiving an 80-game suspension on June 21. Since then, Oakland starters have accumulated 1.7 WAR, good for seventh-best in baseball, though their 4.85 xFIP suggests they’ve been a bit fortunate.

Mike Fiers, Brett Anderson and Chris Bassitt have been serviceable starters, but all three are outperforming their FIPs by a wide gap. Tanner Anderson and Daniel Mengden are passable options, but the rotation is clearly Oakland’s weakest part of the roster. Critically, Oakland’s internal prospective reinforcements all have question marks. Jharel Cotton and Sean Manaea are on track to rejoin the team in August, but they’re both returning from serious injuries: Manaea hasn’t pitched this year and Cotton has been out since 2017. The two top pitching prospects in the organization in A.J. Puk and Jesus Luzardo, meanwhile, have thrown only a handful of innings this season, and probably aren’t realistic options to contribute down the stretch. The A’s need an arm or two, and they got a cheap one in Bailey.

Because the Dodgers are paying $22.45 million in salary owed to Bailey for the 2019 season, Oakland is on the hook for just the remaining $250,000. As far as prospect cost, a top-20 prospect isn’t nothing, but Merrell has a long road ahead of him. As Eric and Kiley wrote back in March, a move to the outfield is likely in his future, and there isn’t much power at all in his bat. His speed makes him interesting, but he’ll need to take a big step forward to profile as a regular.

That’s all that it cost to bring Bailey to Oakland, an organization that has done well with similarly beleaguered pitchers recently. Last June, they signed Edwin Jackson — a pitcher who hadn’t posted an ERA under 5.00 since 2015 — and watched him spin 92 innings of 3.33 ERA ball the rest of the year. They also coaxed 110 splendid innings out of Trevor Cahill’s oft-injured and sporadically-effective right arm. The A’s have been a good home for pitchers who once seemed over the hill, and perhaps Bailey will continue the pattern. Just seven months ago, he was a cast-off. But in Kansas City, he showed he wasn’t done. Now, in Oakland, he can show how much more he has left.

Robert Stock is following a breakthrough season with a rocky season. Last year, the right-hander broke into the big leagues at age 28, and logged a 2.50 ERA in 32 appearances out of the Padres’ bullpen. This year he’s spent the bulk of his time with San Diego’s Triple-A affiliate, and scuffled in his smattering of opportunities in The Show. Currently on the IL with a bicep strain, Stock has a 10.13 ERA in 10-and-two-thirds innings of work.

There’s more to the Robert Stock story than his late-bloomer status and overall pitching prowess. When I talked to the former Los Angeles-area prep at Petco Park recently, I learned that he’s a converted catcher with an unorthodox workout routine.

“I use a training system called EVO UltraFit,” Stock told me. “It involves electrodes, and obscure ways of lifting weights. You’re doing things like jumping off of stuff, and catching things that are falling.”

Watching an ESPN feature on a former NFL safety was the catalyst. Learning that Adam Archuleta “found success through this weird training system,” he decided to try it himself. Just 13 years old at the time, Stock traveled to Arizona, “where the guru is,” and proceeded to adopt the program. He’s been a disciple ever since.

An electrodes apparatus was charging at Stock’s locker as we spoke. Read the rest of this entry »
