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.

Billy Hamilton has been a Brave for a little over a week — only since Atlanta picked him up off waivers from Kansas City on August 19 after losing Nick Markakis and Ender Inciarte to injury — and he’s already achieved that highest aspiration for any member of the Braves organization: He humiliated the New York Mets, and on their home turf at that. The play came with the score tied 5-5 in the eighth inning of Saturday’s second game of the weekend series, with Ronald Acuña Jr. at the plate, Rafael Ortega at second, and Hamilton at first. Acuña, who at that point was an uncharacteristic 0-for-4 on the night, wasted no time in taking a Brad Brach hanger on the outer third of the plate softly into left. Then, this happened:

J.D. Davis, the Met unfortunate enough to wind up holding the ball on this particular play, spoke to our own Jay Jaffe after the game:

I was going to make a play to third,” he said, in a clubhouse near-silent after a late loss to a division rival, “and then I saw that the runner [Hamilton] was already like three-quarters of the way … so I just held onto the ball, and I looked at first to see where that runner was. But then as I released it to throw it to ‘Rosie’, he was already rounding third and headed home … I should have just thrown it to ‘Rosie’ and got it in. [You feel kind of] helpless, with Hamilton and his speed … it was just perfect timing. It was a good, high-baseball IQ kind of play.

At this point, it seems like common knowledge that the sinker has fallen out of favor. We’ve covered that development pretty often here at FanGraphs over the past couple of years. In fact, here’s Jeff Sullivan doing just that in a 2017 piece called, “Baseball is Moving Away From the Sinker:”

“The league got a whole hell of a lot better at hitting the low pitch out of the ballpark. Not exclusively the low pitch, but disproportionately the low pitch. Swings started to gear up for elevating the low sinker. This is something that’s continuing today. Where many of those swings have a vulnerability is up, around the belt. The uppercut swing can have trouble connecting with pitches in the upper half, and those pitches have long gotten swings and misses, anyhow. Sinkers? Sinkers are supposed to be low. They’re not so good at the thigh.”

Since then, homer totals have soared and sinker usage rates have fallen. For those still working with a sinker, it’s often their worst pitch. This is true for Noah Syndergaard, Chris Archer, and even a guy like Aaron Sanchez, who has notably reduced his sinker usage since he was traded to Houston.

That doesn’t mean the sinker is entirely dead. The most obvious example of a guy with an effective one is Zack Britton, who’s riding his sinker to a near-80% ground-ball rate this year. Britton’s a unicorn, but there are still several “normal” pitchers succeeding with sinkers too. Look at the top of the pitch value leaderboard, and you’ll see a decidedly normal pitcher with a good sinker in Julio Teheran. 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.

Ronald Acuña Jr., with 34 home runs, 28 stolen bases, and six weeks left in the season, has a chance to become the fifth player to join Major League Baseball’s 40-40 Club. If Acuña’s membership application is approved by feats of baseballing, he’ll join an exclusive fraternity of Jose Canseco, Alex Rodriguez, Barry Bonds, and Alfonso Soriano. Okay, mostly elite.

As someone who apparently became a “veteran” baseball analyst at some point, I’m not always sure if the game has changed or if I have. When I was a kid, there’d be talk of 20-20 clubs, 30 HR/100 RBI guys, and scores of home run milestones. But you don’t hear about these baseball clubs as often as you used to. Has fandom changed this much or have I become jaded about these kinds of statistically interesting accomplishments? Or is that some of the older markers for performance, such as the 400 Homer Club, have become less exclusive institutions to join than a sandwich shop that give you a 10th sub free after buying nine?

The 40-40 Club, on the other hand, still excites me. Part of it could be that Jose Canseco’s charge on his way to becoming the founding member of this fraternity in 1988 was still very early in my Serious Baseball Fandom phase. I’ve loved watching baseball from the age of three, but it wasn’t until a few years later I really became a serious fan of the game, aided by my grandfather getting me a subscription to Sports Illustrated in 1986, a bit before my eighth birthday. While I watched the 1983-1985 World Series games, the 1986 World Series was the first one where I really followed every pitch, watching to the end even on school nights. I can still remember Tim Teufel‘s error as much as Bill Buckner‘s more famous one, and am able to exactly replicate Marty Barrett‘s closed stance and Sid Fernandez’s three-quarters delivery.

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 Atlanta Braves continued their deadline bullpen upgrades by acquiring relief pitcher Mark Melancon from the San Francisco Giants for pitchers Tristan Beck and Dan Winkler.

Coming into today, the ZiPS rest-of-season projections for the Braves, when combined with the FanGraphs depth charts, had the Braves with the No. 19 bullpen in baseball, ahead of only the Phillies, Nationals, and Angels among the plausible contenders. ZiPS is also the more optimistic of the two systems; when you combine ZiPS and Steamer on the FanGraphs Depth Charts, the Braves drop to 22nd.

There’s a misconception that Atlanta’s relief woes are because of Luke Jackson, the team’s closer for most of the season. It’s true that Jackson has only saved 17-of-24 games for the Braves, but save percentage is actually a rather poor predictor of future save percentage, especially when other metrics exist (ERA, FIP, batter OPS, pretty much anything else). Melancon and Jackson are in roughly the same tier performance-wise, along with Shane Greene; the reason the trade improves the team is because it improves the depth of the bullpen, which was a significantly larger problem than the closer himself.

San Francisco trading Melancon (and Ray Black, Sam Dyson, and Drew Pomeranz) does not represent the Giants throwing in the towel on the 2019 season. Prior to these trades, the ZiPS/Steamer combined projections had San Francisco with eight relief pitchers projected to have a FIP below four over the rest of the season. The Giants still retain five of them (Pomeranz was not on the list), more than enough pitching to cover high-leverage relief innings. The team has an improving farm system, but that’s largely due to the first-tier talent at the top of their prospect list: Joey Bart, Marco Luciano, Heliot Ramos, and Hunter Bishop. Much like the Braves’ bullpen prior to today, what the Giants’ system still lacks is depth. Read the rest of this entry »

The Tigers are rebuilding as the Braves have tried to build a bullpen on the fly all season long. The match between the two teams is an easy one to make, and Ken Rosenthal is reporting that the Tigers are close to trading away closer Shane Greene to the Braves. Robert Murray has added the return for the Tigers. Here’s the deal:
Braves Receive:

• RHP Shane Greene

Tigers Receive:

• LHP Joey Wentz
• OF Travis Demeritte

A season ago, Greene racked up 32 saves for the Tigers, but he generally wasn’t a very good reliever. His ground-ball rate at 40% was lower than in previous seasons, and too many fly balls meant too many homers and a 4.61 FIP and an ERA over 5. This season, Greene was able to get back to his ground-balling ways with a sinker/cutter/slider arsenal, and he’s been a pretty good pitcher as a result. Looking at Greene’s ERA might lead one to believe he is a great pitcher, but the underlying numbers don’t completely support that greatness.

Greene has a 1.18 ERA, which is certainly really good. Only Kirby Yates‘ 1.02 mark bests Greene among relievers this season. Expecting Greene to continue to post a 1.18 ERA is folly. He has struck out 29% of batters, which is good, while walking 8% of batters, which is roughly average. His ground-ball rate on the season is 54%, and that’s going to keep the ball in the park and limit damage, but those things alone aren’t enough to take a 3.80 FIP, which is about 20% better than average in these heightened run environments, and move it to a 1.18 ERA.

Greene’s BABIP is .181 and his left-on-base rate is 85%, and neither number is sustainable going forward. He’s also given up six runs on the season which weren’t earned, more than double his total of five earned runs. This isn’t to say Greene isn’t good, but it is enough to say Greene isn’t great. Over at Statcast, his xwOBA is a solid .282, but his actual wOBA is about 60 points lower. Greene is a solid addition to the Braves pen, and 15 years ago, the ERA and saves might have netted the Tigers a top-50 prospect. Today, Greene is another solid reliever among many available at the trade deadline. The Braves are likely to pay a premium for that need, but their top prospects were always going to be off limits.

In a trade that may or may not dissolve Coldplay, the Braves cushioned their bullpen on Tuesday night by acquiring right-handed reliever Chris Martin. Per The Athletic’s Ken Rosenthal, the Braves obtained Martin from the Rangers in exchange for Triple-A lefty Kolby Allard.

The Braves currently have a fairly large lead over the Nationals atop the NL East, and we have them as the favorite (68.5%) to win the division. To this point, the bullpen has been one of Atlanta’s few weaknesses. Braves relievers have posted a 4.75 FIP and accrued -0.1 WAR this season, the sixth worst total in baseball. Walks have been particularly problematic for this crew, as they’ve allowed an 11% walk rate, the second worst mark in the league. A high strand rate has masked the issue somewhat — the ‘pen has notched a 4.03 ERA — but Atlanta needs reinforcements.

Martin should help. After dominating in the NPB — he posted a 91-to-13 K/BB in 88.1 IP back in 2017 — he’s pitched well since returning stateside the following year. In 2019, he’s been fantastic, and he sports a 3.08 ERA (62 ERA-) in 38 innings. His 26.5% K-BB rate is the 15th-highest among the 182 relievers with at least 30 IP, and he recently went nearly two months without walking a batter. He’s also pitched in plenty of stressful situations: Among Braves relievers, only Luke Jackson has a higher average leverage index this year than Martin. Read the rest of this entry »
