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 »

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 »

For a losing team, the Cincinnati Reds have been busy. It’s not just trading players either, as Cincinnati made one of the biggest deadline moves while many contenders slumbered in near-stasis, picking up Trevor Bauer with an eye towards retooling for the 2020 season. Only three of the eight players in Wednesday’s lineup were also in the lineup on Opening Day: Tucker Barnhart, Eugenio Suárez, and José Iglesias. Chief among the new additions is the recently called-up Aristides Aquino, a big slugger lurking far back from the head of the team prospect lists coming into the season. After a fairly unimpressive minor league career, Aquino has feasted on the major league bouncy ball in 2019, slugging 28 homers in 294 AB in the formerly pitcher-friendly International League and then a shocking 11 homers in just 20 major league games.

Aquino was not some elite prospect finally being called up. The Reds have only received the benefit of getting a look at Aquino because they decided to use their ABs in a now-lost season in a productive way. If the team hadn’t dropped Matt Kemp or traded Yasiel Puig, choosing to go with the known quantity in a mistaken attempt to goose attendance (there’s no evidence this actually works), there wouldn’t have been as many opportunities to assess Aquino or Josh VanMeter or Phil Ervin in the majors. They now have more information on these players — how they’ve played at the big league level — and that information can have a positive effect on the decisions they make on how to win the NL Central or a wild card spot in 2020. Even picking up veteran Freddy Galvis, a 2.0 WAR player, for free has a value to a team like the Reds given his one-year, $5-million option for 2020. Scooter Gennett was always likely to be gone, but Galvis may not be, and now the Reds have another player who they can choose to start in 2020 or trade over the winter.

The Reds have been fortunate in these decisions, but I would have been in favor of this calculus even if Aquino/VanMeter/Ervin had been terrible. My fundamental belief is that among hitters and pitchers, teams have roughly a combined 12,000 plate appearances/batters faced to work with every year, and as many of them should be devoted to trying to win games as possible. Maybe they’re not 2019 wins — maybe they’re wins in 2020 or 2023 or 2026. But even players not working out gives you information; if Aquino came to the majors and hit like Lewis Brinson, it would still give the Reds data they didn’t have before. You don’t acquire that kind of knowledge when you’re a 90-loss team still penciling Billy Hamilton or Chris Davis into the lineup on a daily basis. 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.

As soon as I finish this piece, I’m going to get ice cream. There’s a soft serve frozen yogurt place owned by a surprisingly fastidious stoner about a mile from my house, and I go there once or twice a week. If I told you there are 10 rotating flavors, with chocolate and vanilla as constants, how long do you think it would take you to learn what I like by watching me fill my bowl (there are all sorts of bowl-packing jokes on the store’s signage)? How many times would I need to go in there and pull that soft serve lever before you’d know that vanilla is actually pretty high on my pref list, and that only a few things, like coconut or coffee, will pull me away from it? Or that I avoid all of the fruit flavors?

How long before we can start to identify team regime patterns in player acquisition, and start talking about team preferences with confidence, the way we do when we say that progressive clubs look for common arm slots and hand positions, or fastballs that spin? The current Marlins regime has basically now been in place since the fall of 2017, when Gary Denbo was brought in as Vice President of Scouting and Development. Miami has made a lot of seller’s trades during that year and a half, and they clearly have a type, especially when you look at their amateur acquisitions. Yesterday, that type came further into focus after a deadline deal with the Arizona Diamondbacks. Here’s the trade:

Marlins get:
SS Jazz Chisholm

Diamondbacks get:
RHP Zac Gallen

The Tampa Bay Rays are in the thick of a playoff hunt. The Miami Marlins are not. Both teams behaved accordingly today, with the Rays sending Ryne Stanek and Jesús Sánchez to the Marlins in exchange for Nick Anderson and Trevor Richards. This trade, as many trades do, seems to favor the Rays, though all four players changing sides are interesting in one way or another. I wouldn’t fault you for thinking the Marlins might come out ahead in the end.

To my eyes, the gem of the trade is Nick Anderson. An out-of-nowhere success this season, Anderson is the kind of high-octane pitcher modern bullpens covet. He also won’t reach free agency until 2025, which means that he’s doubly attractive to the cost-conscious Rays. A rate monster, he boasts an eye-popping 37.1% strikeout rate, ninth-best among relievers this season, courtesy of a spinny four-seam fastball and devastating breaking ball.

While his results have been inconsistent this year, it’s not for lack of underlying numbers. He surrenders hard contact, with a 6th-percentile exit velocity allowed and 4th-percentile hard contact rate, but makes up for it with the aforementioned heaps and bales of strikeouts. It’s too early in his career to know how much of a problem the contact will be, but if his underlying talent there is close to league average, he’s immediately one of the best relievers in baseball.

Want a best-case comparison for Anderson? Think of Ken Giles. His fastball doesn’t boast quite the same top end as Giles, but they’re both four-seam/breaking ball pitchers who mix the two pitches almost equally and post ludicrous swinging strike rates. Anderson is at 17.4% for the year, while Giles is at 17.1% over his career. Giles has also had intermittent struggles with hard contact, though he seems to have worked through them en route to a 1.6 FIP this year. Anderson’s upside might not be quite that high, but his stuff is tremendous. Read the rest of this entry »

On Saturday, the Marlins and Twins pulled off a pre-deadline swap.

First, the trade:

Miami gets:

1B Lewin Diaz

Minnesota gets:

RHP Sergio Romo
RHP Chris Vallimont
Player to be Named Later

This deal’s immediate big league relevance centers around 36-year-old Romo, who has had an incredible career for a reliever, especially one who throws as hard as he does. Romo’s fastball has never averaged more than even 90 mph, topping out at 89.9 mph during his rookie year, while average relief fastballs now hum in at 93.6 mph. His 9.8 WAR ranks 15th among relievers since he debuted in 2008, and splitter wizard Koji Uehara is the only other soft-tosser ahead of him.

Most of our readers have probably seen enough of Romo over the last decade to know that he’s been exceptional because of his ability to locate, and change the speed and shape of, his trademark slider. Hitters know that slider is coming — he’s thrown it roughly 53% of the time during his career, second most to Carlos Marmol among all pitchers with 400 or more innings since Romo debuted — and yet Romo’s surgical placement of the pitch just off the plate, equal parts enticing and unhittable, has had big league hitters flailing away at it across more than a decade now.

Six weeks ago, the Miami Marlins looked dead in the water. They were 10-31 at the time, and given their tough schedule ahead, they had a small yet tangible shot at eclipsing the 1962 Mets’ record for the most losses since integration. Jay Jaffe covered Miami’s putrid start, and the details were very grim indeed:

They’ve lost seven games in a row… They scored a grand total of eight runs in that span, never more than two in a game… Did I mention that it’s been a full week since the last Marlins position player drove in a run, or 11 days since one of their players homered? Or that it’s the team’s only homer this month, hit by a 29-year-old rookie named Jon Berti?

Miami’s ineptitude at the plate explained most of the trouble; the Fish were scoring barely 2.5 runs per game. They were also on pace to hit fewer than 100 home runs, an astonishingly feeble output in today’s dinger-happy game.

But in baseball, yesterday’s trends are tomorrow’s distant memory. Miami commenced a six-game winning streak the day Jaffe’s post went live, and they’ve gone 20-17 since publication — an 88-win pace. Obviously, they’re not that good: even terrible squads can string together a .500 stretch over 40 games. Still, the club’s recent surge has given them a better record than four other teams in the majors. Even stranger, the Marlins are… gulp… surprisingly entertaining! Read the rest of this entry »
