The book on Luke Weaver was written before he had played a game of professional baseball. Great changeup, good fastball, no third pitch. I mean “the book” metaphorically here, but I also mean it literally. Here’s Eric Longenhagen on Weaver before the 2017 season:

“Those who have questioned Weaver’s upside (myself included) did so because, in college, he lacked a good breaking ball. Weaver’s fringey curveball remains so today, but he’s a good athlete who has developed plus command and added an average cutter to his repertoire in pro ball.”

Cardinals fans got two years of data to back up that assessment — a scintillating 2017 (3.17 FIP, 28.6% K-rate) and a frustrating 2018 (4.45 FIP, fewer strikeouts and more walks) were worth a combined 2.7 WAR, but between underperforming his FIP and losing his rotation spot in the second half of 2018, Weaver felt like a surplus arm. The changeup and sneaky good fastball were as good as advertised, but batters consistently teed off on his curve. When Weaver and top catching prospect Carson Kelly were sent to the Diamondbacks in exchange for Paul Goldschmidt, it felt like a needed change of scenery for both of them.

If the book on Weaver was written while he was still in college, it’s a safe bet that he’s had time to read that book. He has worked towards developing a better breaking ball more or less every offseason of his pro career, and 2019 was no exception. This time, though, he had technological help. He bought a Rapsodo, a portable pitch-tracking camera, and used it to work on his curve. He took his cutter (or is it a slider?) out of mothballs, telling David Laurila he was picking up the hybrid pitch after years of being mainly fastball/change/curve.

Michael Pineda has always had a bit of a weak spot in his pitching profile. From his debut in 2011 until his 2017 ended with Tommy John surgery, he threw 680 innings while allowing 91 total home runs. That translated to a 1.20 HR/9, putting Pineda in the bottom 20th percentile in the league among pitchers with at least 650 innings pitched.

Despite the eye-catching rate, the home runs were a manageable issue; Pineda’s FIP in those years was a fine 3.60. More than avoiding home runs, Pineda needed the health he enjoyed between 2015-16 to be an average starter. Even setting aside the Tommy John, his time in the majors is riddled with stints on the disabled list for a variety of maladies. Now in 2019, with the health of his arm finally restored, the home run issues looms larger.

After his first nine starts of the year, Pineda is leading the majors in home run rate among qualified pitchers with a 2.49 HR/9. Following his last start, he became the first Minnesota Twins pitcher to allow at least three home runs in consecutive outings since Bartolo Colon in 2017.

This is still a small sample, and Pineda’s home run rate will probably go down as he keeps pitching. However, given his previous home run issues, the recent spike merits a closer look.

First, let’s examine his fastball. Of the 13 home runs he has allowed this year, six have been against fastballs in the middle or upper part of the zone. Pineda has always liked to throw his fastball in the zone, challenging hitters with good gas, and he has been doing exactly that this year. Read the rest of this entry »

When the Red Sox called up Michael Chavis on April 19, they were 6-13 and had no shortage of troubles. Every member of their rotation save for David Price was regularly being lit up like a pinball machine, and their no-name bullpen was shaky as well. Reigning AL MVP Mookie Betts was hardly himself offensively, and both Jackie Bradley Jr. and Steve Pearce were impossibly cold. Amidst all of that, the team’s hole at second base was just one more problem, albeit similar to last year, when even replacement-level play in the absence of the injured Dustin Pedroia did little to prevent them from winning a franchise-record 108 games as well as the World Series.

Just over one month since Chavis’ arrival, the Red Sox are now over .500 (25-22). Their pitching has come around, as has Betts, and their leading hitter in terms of both slugging percentage (.592) and wRC+ (156) is Chavis, a 23-year-old righty-swinging rookie with “a bit of a beer-keg physique” (h/t Baseball Prospectus), one who had never played second base before this season. His nine homers (in 113 PA) is tied with J.D. Martinez for second on the team behind Mitch Moreland’s 12. He homered in Boston’s wins both Sunday against the Astros and Monday against the Blue Jays. Here’s the former, in which he drove a Wade Miley cut fastball 420 feet, a towering shot over the Green Monster:

Long blasts are hardly a rarity for Chavis. Despite his late arrival, he’s tied for fourth in the majors with six homers of at least 420 feet, and he had another estimated at 419 feet. His average home run distance of 426 feet ranks seventh among players with at least 50 batted ball events (he has 68). Monday’s 389-footer off of the Blue Jays’ Edwin Jackson was just his second homer shorter than 400 feet.

Two months ago, Chavis barely registered as a player likely to make an impact on the 2019 Red Sox, in part because he had just eight games of Triple-A experience to that point along with 100 games at Double-A. Our preseason forecasts estimated he’d get just 14 big league plate appearances. Now he’s one of the players who has helped to salvage their season. So what gives? Read the rest of this entry »

It was rainy, it was short, and yet, it was the first time in 382 games that a Chicago White Sox pitcher had recorded a complete game.

On Saturday, in an effort that required just 78 pitches, Lucas Giolito became the first White Sox pitcher to throw a complete game since Chris Sale on September 16, 2016. He allowed just one run on three hits and struck out four.

The catch? Let Giolito explain it himself. As he told NBC Sports Chicago after the game, “I don’t consider it a complete game until I get nine.” Indeed, Giolito’s effort to snap a long stretch of bullpen usage was only five innings long. The game only lasted an hour and 31 minutes, if you choose to exclude the three-hour delay. A rain-soaked Chicago took care of the rest.

What’s lost in this whole story is that Giolito was solid on Saturday yet again. He’s had an up-and-down career so far, from being the Nationals’ prized pitching prospect to struggling in his first taste of the majors in 2016 to being the centerpiece in the Adam Eaton trade to posting the worst K-BB% among starters last year. But in Saturday’s start, never mind its length, Giolito lowered his ERA to 3.35. His 3.00 FIP is sterling. His 1.3 WAR in just 43 innings represents a 1.7-win improvement over his career total entering this season.

In sum, Giolito went from being league-worst to pretty, pretty good. The next step — the excellence — still comes in flashes, as it often has over his young career. Since the start of May, Giolito has posted a 1.85 ERA with 27 strikeouts to just eight walks over 24.1 innings. By WAR, he’s been the eighth-best starter this month. Read the rest of this entry »

The Mets were one of the more active clubs this offseason, pulling off a big trade for Robinson Cano and Edwin Diaz while signing Wilson Ramos, Jeurys Familia, and Jed Lowrie to free agent contracts. Through 46 games, the team is just 21-25, and multiple reports calling manager Mickey Callaway’s job “safe” have been issued, including a team meeting with GM Brodie Van Wagenen, which is never a good sign. The team had lost five straight games before their win last night, including a three-game sweep to the lowly Marlins despite both Jacob deGrom and Noah Syndergaard pitching in the series. The final two games saw the team shut out offensively. There’s something wrong with the Mets, and a lot of people are at fault.

During the course of a 162-game season, there are going to be stretches where teams don’t play well. The Mets getting swept by the Marlins looks pretty bad because it just happened, but bad teams sweep good teams a fair amount during the season because three games represents less than two percent of the season. The Mets are at 21-25 — fewer wins than they would like — but keep in mind, what the Mets are doing now isn’t a massive departure from the team’s projections at the beginning of the season. This is what our playoff odds projections looked like before the season started.

Things didn’t exactly go his way on Saturday, but Ryan Feierabend’s start for the Blue Jays against the White Sox — a four-inning stint that resulted in defeat — was noteworthy, not just the kind of thing you don’t see every day, but the kind of thing you don’t see every decade. Not only had Feierabend, who began throwing the knuckleball during a four-year stint in the Korea Baseball Organization, not started in the majors since September 23, 2008 (when he faced the Angels’ Vladimir Guerrero, ahem), or appeared in a major league game since July 27, 2014, but it had been nearly 19 years since a left-handed knuckleballer pitched in the majors, and more than 20 since the last one made a start.

As I noted in February, when the 33-year-old Feierabend, who found little success in parts of four major league seasons before going to Korea, signed with Toronto, the practice of throwing the knuckleball has fallen upon hard times during the pitch-tracking era:

Last year, Boston’s Steven Wright was the only pitcher (as opposed to the occasionally dabbling position player) to throw a knuckleball, but between complications stemming from left knee surgery and a 15-game suspension for violating the league’s domestic violence policy, he threw just 53.2 innings. As he’s currently serving an 80-game suspension for a PED violation — making him the first major leaguer to attain that dubious dual distinction — the pitch needs a new champion. Enter Feierabend, who by virtue of even one appearance resurrected a long-dormant line. Read the rest of this entry »

UMP: The Untitled McDongenhagen Project, Episode 15

This is the 15th episode of a sorta weekly program co-hosted by Eric Longenhagen and Kiley McDaniel about player evaluation in all its forms. The show, which is available through the normal FanGraphs Audio feed, has a working name but barely. The show is not all prospect stuff, but there is plenty of that, as the hosts are Prospect Men.

This episode is the first, and possibly only, Important Episode, focusing on news of a potential international draft, as reported by our guest, ESPN’s Jeff Passan. Please support him by purchasing any Elmo products, authentic or knock-off.

0:20 – Jeff outright rejects the intro
1:22 – Kiley tries again, leaning into Jeff’s unlikability
2:09 – Jeff breaks down the news as he’s reported it
2:33 – Jeff is under attack in his own car and makes metaphorical lemonade
4:15 – They touch on the human issue of how the pro players who are discarded by clubs in developing countries are handled
6:20 – The soon-to-be-best-prospect-in-baseball instance of Wander Franco and his experience in this system
8:42 – Comparing the typical Latin prospect to a typical suburban American one, and where the MLB Players’ Association and MLB come in
11:10 – MLB’s morally-driven approach to human trafficking re: Cuba could impact how the international draft is put together
12:50 – The MLBPA’s response to Jeff’s report and does a point the MLBPA makes suggest MLB planned this whole progression out years in advance?
15:40 – Is this just step one of a few for MLB? How did the MLBPA allow us to get here?
17:50 – Why don’t the international pools track the draft pools? How close should they be?
20:45 – How to use hard slotting to solve some problems and then transition into making July 2nd into a TV event and a pilot program for doing it with the domestic draft.
24:35 – Where does this go next? What’s the timetable for making the change? Can Jeff really learn Spanish?
25:40 – Elmo makes an appearance?
26:55 – Jeff details how anti-social he is on planes and how this prepares him to be a general manager
29:30 – Eric joins the podcast for the second segment and answers Kiley’s burning question
31:00 – Eric and Kiley break down the international draft possibilities for each stakeholder, starting with the 5-10 most efficient MLB clubs in Latin America. Kiley broke down earlier this year what the ROI is on an international dollar spent and is it big.
33:30 – They break down the bottom tier of clubs, with less infrastructure and with smaller staffing budgets
36:00 – The big unanswered question: how much will MLB assert themselves in controlling the scouting environment?
40:45 – The MLB Players Association’s role in negotiations. Kiley mentioned in this year’s July 2nd preview that clubs can get steroid tests on prospects as young as age 13, which can’t possibly be the status quo for long.
42:13 – The next stakeholders: the kids that are signing an international amateurs
46:30 – What happens to a 17 year old who opted not to sign as a 16 year old? How would the structure of the draft affect this? Would it lead to trading of picks? A TV event?
51:25 – In fairness, this would also be great for us
52:27 – MLB’s role and motivations in improving this situation. Here’s the first time Kiley wrote about MLB likely using the overage money to help institute a draft.
58:30 – Eric’s experience watching fringe international prospects get released from a complex
59:55 – Could this indirectly affect the amount of minor league teams?
1:02:15 – The humanitarian element, particularly in Venezuela
1:04:00 – The last major stakeholder: the buscones
1:07:00 – The least important stakeholder: Kiley and Eric

Dan Szymborski: Unleash the Chatken!

Dan Szymborski: That’s a tricky thing in that’s it hard to really separate out a hitting coach’s contribution. It’s more of a leadership role for the manager to figure out than anything that is data driven.

Dan Szymborski: Unless someone smarter than me has found a way to isolate hitting coaches.

When we look back on this era of baseball in future times, exhorting children to get off our lawns, nobody shed tears of pity for the San Francisco Giants. After all, the Giants of this generation made the World Series four times and won three of them, a difficult, probability-crushing feat in a world where six division winners and four wild card teams make the playoffs. It was a team that featured most of the grandest years of one of the best players anyone will ever see — no, Dusty Baker, not Pedro Feliz — before that mantle was handed off.

After such a highlight-filled epic, the problem is what comes next? In literature, you have the ability to just end the story. King Arthur’s body sails to Avalon; Beowulf lives another 50 years; Frodo sails away. Or maybe the author doesn’t finish the books, and a TV adaptation shoves three years’ worth of material into 13 episodes. But baseball always has another sequel, another tale with new protagonists and antagonists and unfortunate Joe West cameos, and these San Francisco Giants have bungled the end of their current tale.

The Outfield Conundrum

We’ve talked a lot about Cleveland’s failures this offseason to address their outfield situation, but San Francisco’s problems are long-standing and arguably even less excusable. While one can rightly complain about the amount of chutzpah (and possibly arrogance) needed for a contending team to just let a major weakness slide going into the season because their competition is extremely weak, the Giants were under no such illusion. The NL West provided five playoff teams combined in 2017 and 2018 and the Dodgers were the NL champs in both seasons, so the “Hey, we play the Tigers and Royals a lot” excuse doesn’t hold. Not to mention that the Dodgers, while losing their partial season from Manny Machado, reasonably expected to get a full season from a returning Corey Seager, which is as good as a major free agent signing.
