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 — Dylan Cease, Tyler Duffey, and Buck Farmer— on how they learned and developed their curveballs.

——

Dylan Cease, Chicago White Sox

“I first learned a curveball when I was 12 or 13 years old. I think a coach probably taught me, but it’s tough to say that far back. I do know that I didn’t throw a whole lot of curveballs back in the day; it was mostly fastballs.

“When I got to pro ball, it took me… I really didn’t know anything about how to throw one. I had to figure out how to throw it like a fastball, how to get it to stay on a fastball plane, how to throw it with arm speed. At first I wanted to baby it. It kind of had a loop in it. I needed to work on things like the shape, and how it came out of my hand.

“It was a regular curveball until last year when I got to Double-A and changed to a knuckle curve. I was talking to Dane Dunning. I liked the shape of his curveball. I said, ‘I feel like mine is a little loopy; how do you do that?’ He showed me his knuckle curve grip, which I’m pretty sure he got from James Shields — indirectly from James Shields — and throwing it like that added a bunch of extra spin and drop.

Yu Darvish’s 2018 could hardly have gone any worse. Fresh off of signing a six-year, $126 million contract with the Cubs, he made just eight starts before triceps tendinitis and a stress reaction in his right elbow ended his season. The Cubs made the playoffs, but Darvish could only watch their maddening 13-inning loss to the Rockies and wonder what could have been.

When Darvish struggled to start 2019, the situation seemed to go from frustrating to dire. His first eight starts were horrendous, rife with walks and home runs. He had been one of the most exciting pitchers in all of baseball, all strikeouts and gadget pitches, a highlight waiting to happen. He’d been a thrilling rookie, a prized deadline acquisition, and a top-tier free agent. Was he now on the downswing of his career, adding expensive journeyman to his list of accomplishments?

As it turns out, he wasn’t. As Devan Fink chronicled, Darvish turned his walk problems around, going from the pitcher with the most walks in baseball to the pitcher with the least. Since a disastrous outing in early May where he walked six Marlins, he’s been the third-best pitcher in baseball by xFIP, fourth-best by strikeout rate, and in the top 15 in WAR. In the second half, he’s been even better than that, combining a 37.2% strikeout rate with a 2.2% walk rate. His ERA, FIP, and xFIP are all in the mid-twos.

This fully actualized version of Darvish is what his flashes of brilliance through the years had always hinted at. The bottomless arsenal of pitches — he picked up Craig Kimbrel’s knuckle curve in a week — made him a delight to watch, the strikeouts coming from every conceivable angle, fastball following cutter following curve. The Cubs were off to a hot start, 22-13 even after Darvish’s disastrous turn against the Marlins, and now they were adding one of the best pitchers in baseball.

But while Darvish returned to form, the Cubs backslid. The team has gone 60-61 since that date, falling from the top of the division to nearly eliminated from postseason play. Darvish has made 23 starts in that time, and the team has gone 9-14 in those games. Wins and losses are no measure of pitcher quality, but Darvish has gone 4-5 over that timeframe. Even in the second half of the season, when Darvish went full supernova, the team was only 6-6 in his starts heading into this past Sunday. Read the rest of this entry »

With a four-game sweep that took Chicago’s playoff odds from likely to long-shot, the Cardinals put the Cubs’ season in the trash like an uneaten commemorative cake. Due to the Cubs’ recent run of success, and the painful way the club lost four, one-run games at home (while holding the lead or being tied in the ninth inning in three of those games), their fall is the most-attention grabbing aspect of the series (and we’ll get to that). But the sweep was massive for the Cardinals in its own right. Look at the Cardinals’ odds to win the division in the second half:

While the Cardinals still have some work to do, the division title is very likely theirs after failing to make the playoffs the last three seasons. At the beginning of the series, the team had some ground to cover, with a 58% chance at the division. Losing the first game of the series likely would have taken those odds below 50%. Despite the Brewers winning four straight, the Cardinals were able to push their chances upward due to their three-game lead over Milwaukee with just six games to go, while also eliminating their rival from division contention. The series might be viewed as microcosm of the season for St. Louis. The Cardinals offense was typically inconsistent, scoring nine runs in one game, and just nine total runs in the other three. Jack Flaherty pitched fantastically, continuing his run as the NL’s best pitcher in the second half. The bullpen was solid despite multiple short starts from the rotation, and the defense played its part, turning seven double plays.

A year ago, the Cardinals played the role of the Cubs. After going 39-23 in the second half after firing Mike Matheny just before the All-Star Break, the Cardinals got their playoff odds up to 79.5% with series against the Brewers and Cubs to close the season. But the Brewers swept the Cardinals in St. Louis, dropping the team’s playoff odds down to 19.6%. When they dropped the opener to the Cubs, those odds fell under 1% and their season was essentially over in four games. Speaking of a season essentially ending after four tough games:

When ESPN’s Buster Olney reported on Friday that Yankees right-hander Domingo Germán will not pitch again this year, either in the regular season or the postseason, in the wake of a reported violation of the Joint MLB-MLBPA Domestic Violence Policy and a likely suspension, it was a instance of the league and the players’ union lucking into the right outcome. While players suspended for violating the Joint Drug Agreement by taking performance-enhancing drugs have been ineligible to participate in that year’s postseason since 2014, that’s not the case for those suspended under the DV policy introduced in August 2015. Not only does that make for a jarring incongruity given the relative severity of those transgressions, allowing recently suspended players to participate in the playoffs can lead to unsavory behavior on the part of teams, as we’ve seen multiple times since the policy was introduced. It’s time for the players and the league to close this loophole.

Germán was placed on administrative leave on Thursday in connection with an incident that reportedly took place at the pitcher’s residence late Monday or early Tuesday, after the pitcher and his girlfriend appeared at CC Sabathia’s charity gala. The 27-year-old righty, who in his first full major league season has emerged as a viable rotation cog, had pitched in relief of Sabathia on Wednesday night in preparation for a more flexible role come the postseason. The announcement of his placement on leave dimmed some of the luster of the Yankees’ victory over the Angels later that night, which not only marked their 100th win but clinched their first AL East title since 2012.

No police report was filed in connection with the incident at Germán’s residence, and no charges were filed. The incident was reported directly to the league, which, according to The Athletic’s Lindsey Adler, conducted a preliminary investigation on Tuesday and Wednesday, interviewing people around the team. While Yankees manager Aaron Boone said he heard “whispers” of an investigation on Wednesday, the team was not informed until Thursday morning that the pitcher had been placed on administrative leave. Via Adler:

“I learned on the drive in that he was going on administrative leave,” Boone said Thursday afternoon. “Heard some of the whispers and whatnot, but this is a Major League Baseball investigation and issue. We’re just trying to be as cooperative as we can while this goes on.”

A player can be placed on administrative leave for up to seven days, though that period can be extended; during that time, he is paid but not allowed to have any contact with his team. By inference, the mere placement of a player on leave means that the league and the union agree that the allegation in question is substantive — that there is enough evidence to merit preventing him from playing. As Adler noted, “[S]ources told The Athletic the union had the option to appeal his immediate placement on administrative leave but did not take the opportunity to do so.”

Not every player suspended under the policy was placed on leave beforehand, but it is worth noting that the only two of the 14 players investigated who were not suspended, Yasiel Puig and Miguel Sanó, did not require any leave, as the allegations pertained to incidents that took place in the offseason. Neither was ultimately disciplined due to insufficient evidence that they violated the policy. Read the rest of this entry »

Jay Jaffe: Good afternoon, folks, and welcome to another edition of my Monday chat. Excuse the slow start on my part – I’ve got a piece on Domingo German, DV suspensions, and the postseason that’s going live soon and that requires more attention than most posts when it comes to an editorial pass. On a lighter note… well, things aren’t great for Team Entropy (update coming tomorro) but we’ll manage. And now, on with the show…

12:06

Jay Jaffe: I did not actually watch much of it, alas. Because the weather is so good here in NYC, and because the next few weekends will be so hectic, I spent much of my weekend with my daughter — her first trip to the Bronx Zoo on Saturday and then first to the Metropolitan Museum on Sunday. Very fun times. Less so for the Cubs, apparently. Between their mounting injuries and the ongoing failures of Craig Kimbrel — who, let’s face it, can’t possibly be at 100% right now — it’s a grim ending for them, and a bummer for #Team Entropy. It’s an impressive showing by the Cardinals, and the fact that the Yelich-less Brewers have risen to the occasion while the Cubs have fizzled is impressive as well.

12:09

Jay Jaffe: Given that the Nationals have rebounded from their dreadful start to (likely) make the playoffs, I don’t see Davey Martinez getting ousted. If it’s an NL East landing spot for him, I suspect that the Phillies are the more likely destination — particularly when held in contrast to the Mets; i can’t see them willing to pay his high salary or see him willing to sign on for the chaos that comes with working for the Wilpons. Maybe the Padres, but as with Philadelphia, the firing of the managers often suggests that the GM is next on the chopping block, so I’m not sure how attractive either scenario is.

All season, the Milwaukee Brewers were a band propped up by a stud lead guitarist. The drummer was often off-beat, the singer was pitchy, the rhythm guitarist was clearly only in the band because he was the singer’s kid brother, and the bass player was … well actually, the bass player was pretty sweet, too. But man, could that lead guitar shred. He was the reason the band could book any gig in town, the standout performer every night. His name was Christian Yelich, and on September 10, he fell off the stage — or rather, he fouled a pitch off his kneecap, and suffered a season-ending fracture. As Jay Jaffe wrote at the time, the injury dampened what were already somewhat long playoff odds for the Brewers. But the band pressed on, undeterred by the loss of their star. And lo and behold, they’ve sounded incredible.

On September 5, our playoff odds put Milwaukee’s chances of reaching the postseason at just 5.6%. Those were worse odds than in-division rivals St. Louis and Chicago, and also put them at lower Wild Card odds than New York and Arizona. They won five straight games before losing Yelich, but that still only raised their chances to 25%. Yelich had already accumulated 7.8 WAR, and was in excellent position to win a second-straight MVP award, and he fell out of the picture. Without him, the Brewers had just one other 4 WAR player, and just six 2 WAR players. That lack of starter-quality depth placed them in the back half of all the teams in baseball.

Every team with fewer 2 WAR players than the Brewers has been firmly out of the playoff race for weeks, and a number of teams in front of them — including Boston, Pittsburgh and San Diego — have been out of the race for a while as well. No contender was more poorly equipped to lose a star player for final month of the season than Milwaukee. At least, that was the way it appeared.

That five-game win streak the Brewers were riding when Yelich hit the IL? It ultimately turned into seven games. They finally lost in St. Louis, but rattled off four more wins after that. Then came another loss, this time at San Diego, followed by four more victories. Overall, the Brewers are 15-2 since September 6. In that time, they’ve raised their playoff odds from 5.6% to 97.1%. It’s one of the best runs any team has put together this season, and given the circumstances, it’s come from one of the last teams one would expect.

A portion of the Brewers’ success can certainly be credited to the competition they’ve faced over this stretch. Of their last 17 games, 11 have come against the Marlins, Padres and Pirates. September is a very fortunate time to run into two last place teams and a third non-contender, but to be fair, the Brewers pushed them around exactly the way they should have. They won 10 of those 11 matchups, outscoring their hapless opponents by a jaw-dropping 60-23 margin. Playoff teams are supposed to look dominant against inferior competition, and that’s exactly what Milwaukee was. Their recent hot streak also included three wins in a row over the Cubs and two victories in three games over the Cardinals, the two most direct obstacles to their postseason hopes.

On the surface, Justus Sheffield’s developmental journey looks pretty smooth. He was a first-round pick back in 2014. He’s been a consensus top 50 or so prospect since the Obama administration — never much higher than that, but only rarely lower (Eric and Kiley had him ranked 60th overall and first in the Mariners system preseason; he’s since dropped to 109th and seventh respectively). His velocity has not materially changed. He’s suffered a few bumps and bruises, but nothing ever sidelined him long. Twenty-three years old now, he’s cracked a big league rotation right on schedule for a high school draftee of his caliber.

Statistically, he’s been consistent as well. With the exception of a very poor early season spell this year, he’s maintained an ERA under 3.40 at every minor league stop. His strikeout numbers have almost always hovered just above a batter per inning, his walk totals around 3.5/9. He typically generates more grounders than flies. Every year, a new level; every year, the same successes.

Yet Sheffield’s path has actually meandered a bit. As a high schooler, the lefty was seen as an athlete who would have no trouble throwing strikes and a guy who could develop three plus pitches. Two years into his career, he effectively pocketed one of them, shelving his curve in favor of a hard slider. He also grew quite a bit soon after the draft. Between the added weight, a new pitch mix, and a difficult delivery to repeat, his control suffered and whispers about a bullpen role grew louder even as he continued missing bats. His velocity, while stable in the aggregate, has periodically fluctuated on either side of the low-90s. We’ve learned that Sheffield’s fastball has a very low spin rate (more on that later).

He also got traded twice. On the one hand, Sheffield has had the opportunity to hone his craft under the tutelage of two of the sport’s finest pitching development staffs. On the other, those same clubs ultimately decided to work with different pitchers. As he’s matured, and as his fastball looks less like a bat-misser and his changeup remains a work in progress, he’s increasingly relied on his slider. The soothing consistency in his production belies a conflict between the quality of that slider and the reality that he must throw something else eventually. How that conflict resolves itself will shape his ultimate role.

The bullpen has long been the logical end point here. As a starter, Sheffield sits in the low-90s, touching 95 or a tick better at his strongest. In relief, he’d throw even harder. Pair increased velocity with a slider that earns a whiff nearly a quarter of the time he throws it, and you’ve got a late-inning reliever. Lefties, even ones with serviceable changeups, usually peak as eight-inning guys out of the pen. But on paper, Sheffield’s cocktail is good enough to close. Read the rest of this entry »
