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 — Nestor Cortes Jr., Randy Flores, and Vince Velasquez — on how they learned and developed their sliders.

Nestor Cortes Jr., New York Yankees

“When I first got drafted, I was just fastball-curveball-changeup. One of my pitching coaches in Rookie ball, Jose Rosado, told me I needed [a slider]. I was throwing a bullpen and he was, ‘Hey, you’ve got the slow curveball, and you’ve got your heater. There’s about a 15 mph difference, so you need something in between.’ We started messing around with the grip.

“It’s come a long way since then, but there’s still a lot of room to improve it. It’s basically like a cutter, and I’m trying to get more depth to it. I’ve tried to make it better, but I haven’t been able to get the result I wanted, so when I was back in Triple-A this year I went back to the one that’s more like a cutter. But I still call it a slider. It’s bigger and slower than a true cutter.

“I’m trying to create more spin with it. I’m substituting the velo for spin, trying to get more break. I’m also kind of messing around with the grip. I’m keeping it the same to where I can feel I’m ripping through it, but I’m maybe getting more on top of it, to where I can create the angle of my fastball. I think my fastball angle is good with the slider from that slot. Read the rest of this entry »

This is the fifth of a six-part series — the AL East, AL Central, AL West, and NL East pieces have been published — in which I’m highlighting each team’s most notable free agents and how it could fill the resulting void on the roster. A player’s rank on our recently released Top 50 Free Agents list, along with Kiley McDaniel’s contract estimates from that exercise, are listed where relevant. In some cases, the team already has a capable replacement ready to step in. In others, it’s clear the team will either attempt to re-sign their player or look to the trade or free agent markets for help. The remaining cases are somewhere in between, with in-house candidates who might be the answer, but aren’t such obvious everyday players to keep the team from shopping around for better options.

Here’s a look at the National League Central.

Chicago Cubs | Depth Chart | Payroll

Nicholas Castellanos, OF
FanGraphs Top 50 Free Agent Ranking: 11
Kiley McDaniel’s contract projection: 4 years, $56M

Castellanos had been an above-average hitter for a few seasons, although his fielding has left much to be desired. But for the two months following a trade from the Tigers to the Cubs, he was the kind of hitter — 154 wRC+, 16 home runs in 225 plate appearances — whose bat could more than make up for his defensive inadequacies.

Since the Cubs were the team to witness the 27-year-old at his best, especially at Wrigley Field where he slashed .384/.412/.750 in 119 plate appearances, they would have to at least be open to bringing him back. But with the current state of the roster, that does not appear likely unless they trade Kyle Schwarber. Read the rest of this entry »

In his career, Adam Wainwright has started 330 games, pitched in 410, and thrown 2209 and a third innings, including the postseason. Every one of those games has been in a St. Louis Cardinals uniform, and for at least one more season, his 16th season in the majors, the 38-year-old will pitch for the redbirds. The Cardinals announced the news, though has of this writing, terms have not been disclosed.

Update: Ken Rosenthal is reporting the deal is for $5 million guaranteed with $5 million in potential incentives. The guarantee looks to be a bit of a bargain given Wainwright’s 2019 and is under both Kiley McDaniel and the crowd’s estimates.

Wainwright turned 38 years old near the end of August, but that didn’t stop him from putting up a solid regular season campaign with an even better postseason. He ranked 29th on our list of Top 50 Free Agents, with Kiley McDaniel and the crowd expecting a one-year deal worth between $8 million and $10 million. I wrote the blurb that accompanied those predictions, and noted that Wainwright was in line for a much better deal than the one he had to settle for a year ago:

Heading into last offseason, Adam Wainwright couldn’t have been thrilled to find himself at a point in his career where he had to accept a contract with a low guaranteed salary and a ton of incentives based on games started, but he looks to be in much better shape after meeting those incentives in 2019. The 38-year-old started 30 games and put up a league average FIP and ERA. He was even better in the postseason, with 19 strikeouts in 16 and two-thirds innings to go along with just three walks and three runs. His fastball sits at just 90 mph, but heavy use of his signature curve keeps hitters off balance. It’s difficult to envision Wainwright and the Cardinals separating after 15 seasons, and after the year he just had, his guarantee should be a bit higher than the $2 million he got last winter.

This post is part of a series concerning the 2020 Modern Baseball Era Committee ballot, covering executives and long-retired players whose candidacies will be voted upon at the Winter Meetings in San Diego on December 8. It is adapted from a longer version included in The Cooperstown Casebook, published in 2017 by Thomas Dunne Books. For an introduction to JAWS, see here. All WAR figures refer to the Baseball-Reference version unless otherwise indicated.

Ted Simmons was one of baseball’s true iconoclasts. He denounced the Vietnam War, wore his hair long, nearly became a test case for the Reserve Clause, and was as conversant in 18th century fireplace utensils (yes, really) as he was the tools of ignorance and the curveballs of opposing pitchers. Oh, and he could switch-hit well enough to rank among the position’s best offensively. With eight All-Star appearances, he was hardly unheralded, but Simmons nonetheless tended to get lost among the bounty of great catchers from the 1970s. Seven of the top 16 in the JAWS rankings hail from that decade, including three of the top four, namely Johnny Bench, Gary Carter, and Carlton Fisk. Simmons wasn’t quite their equal, but he ranks 10th, just ahead of Modern Baseball ballot-mate Thurman Munson (12th), with Gene Tenace (13th) and Bill Freehan (16th) not far behind.

Such a concentration of top-tier players at a single position in a given time period is hardly unprecedented, even among those already enshrined. Using the Hall’s own definition of activity — at least one game played in a given season — five enshrined catchers were active every year from 1929-37 except ’30. Every other position except third base (which like catcher, has just 15 enshrinees, the lowest at any position besides relievers) has stretches with six or seven active players, with the seven left fielders from 1975-76 the largest of the recent concentrations.

We’ll learn more about what the 30 teams have in store for the offseason in the coming days. Not in any great detail (and some subterfuge is inevitable), but with varying degrees of forthcomingness, information will indeed be shared. The GM meetings begin tomorrow, in Scottsdale, with media sessions scheduled for Tuesday and Wednesday.

Will your favorite team actively pursue a trade for Mookie Betts? Do they have their eyes trained, and checkbooks already open, on free agents such as Gerrit Cole and Anthony Rendon… or perhaps Andrew Cashner or Jordy Mercer? Answers to those kinds of questions are reliably vague at best, but inquiries of a different ilk often elicit thoughtful responses.

I got a head start on the executive-Q&A front during last month’s NLCS. Eschewing anything roster-related — not the right time and place — I asked St. Louis Cardinals Vice President/General Manager Michael Girsch if he and his front office cohorts had anything cooking behind the scenes. His answer reflected just how much the game continues to evolve.

“We’re kind of reorganizing our baseball development group a little bit,” said Girsch. “The amount of data keeps increasing exponentially. It’s gone from your basic back of a baseball card, 10 or 15 years ago, to TrackMan, to StatCast, and beyond. The infrastructure that worked at one point doesn’t work anymore. When I started, everything was in Excel, on my laptop. That became nonviable pretty quickly, and now we’re moving beyond the servers we have, to other issues.”

Is keeping up more a matter of adding staff, or streamlining the process already in place? Girsch’s response reflected the fact that bigger fish — relative to the here and now — still needed to be fried. Read the rest of this entry »

Here’s the lowdown on Tyler Rogers: A 6-foot-5 right-hander from Littleton, Colorado, he’s the twin brother of a left-hander closer, he made his MLB debut this past August, and he’s a submariner. Moreover, he kills a lot of worms. The 1.02 ERA that Rogers put up in 17 games out of the San Francisco Giants bullpen was augmented with a 69.4% ground ball rate.

Unlike his traditional-arm-slot sibling, he’s not a power pitcher. Taylor Rogers — fittingly, a Minnesota Twin — features a 95-mph fastball and an 83-mph slider. Tyler features an 82-mph sinker and a 73-mph slider. The latter pitch, which the atypical hurler throws roughly a third of the time, is atypical in itself.

“I call it a slider, but it’s almost a curveball,” Rogers said in September. “I kind of curl it like people do when they throw a curveball overhand. It’s the same thing, I’m just bent over doing it. So yeah, basically it’s just a normal curveball grip that I throw from underneath.”

Rogers began dropping down his freshman year of junior college. He did so at the suggestion of a coach, and from there progressively got lower and lower. The transformation to an actual submarine-style delivery came after the Giants took him in the 10th round of the 2013 draft. Irony being what it is, the genesis of the more-extreme verticality was horizontal in nature. Read the rest of this entry »

The Washington Nationals are World Series bound following Tuesday night’s sweep-completing 7-4 win over the St. Louis Cardinals. They couldn’t be much hotter. Since a September 18 loss to the team they just vanquished, the Dave Martinez-managed Nationals have won 18 of their last 21 games.

How remarkable was their turnaround from the 19-31 start that had Martinez firmly in the crosshairs? The 2005 Houston Astros, the 1973 New York Mets, and the 1914 Boston Braves are the only other teams to have made it to the World Series after being 12 games under .500 at any point during the season.

The Cardinals deserve some credit of their own. The Mike Shildt-skippered squad went 47-27 in the second half, then beat the favored Braves in the NLDS. They simply had the misfortune of running into a pitching-rich Nationals team that has now punched its ticket to the Fall Classic.

Here are perspectives from participants on each side, gathered prior to, and after, Games 3 and 4.

Following Game 3, I asked Martinez about team’s confidence level, which is undoubtedly the highest it’s been all season. With the early-season struggles in mind, just how important is confidence to a team’s success? Read the rest of this entry »

Last week, I wrote about some intentional walk decisions that merited further scrutiny. One of them was pretty bad and one of them was a little bad, but both managers advanced to the NLCS — and now, like clockwork, we have more intentional walk decisions to analyze. Playoff baseball is predictable like that, even as it’s unpredictable in other ways.

Let’s take these two chronologically. The Yankees had their backs against the wall, down 2-0 against Gerrit Cole to start the seventh. It got worse quickly, with two of the first three runners reaching base. That gets us to our situation; second and third, one out, and Alex Bregman at the plate facing Adam Ottavino. Aaron Boone put up four fingers; he chose to face Yuli Gurriel rather than Bregman.

The surface level math on this one doesn’t look that bad for Boone. The trail runner here simply doesn’t matter that much; if Bregman scores, it’s 5-0, and three innings to score five runs is a tall task against Gerrit Cole and the best relievers the Astros can muster. To approximate the lower run-scoring environment they’re facing, I lowered the run environment in our WPA Inquirer to 4.5. The decision hardly hurt the Yankees; their odds of winning fell from 12.3% before the walk to 12.0% afterwards.

When an intentional walk only costs 0.3% of win expectancy when ignoring batters, it’s more often a good one, and a cursory look at Bregman and Gurriel’s wOBA agrees with that. That doesn’t even add in platoon splits; Gurriel has a reverse split in his major league career, and even regressing it back to the mean leaves him only 3% better against lefties than righties. Bregman, meanwhile, clocks in at 6.8% better against lefties than righties post-regression.

Put that all together, and Gurriel’s projected wOBA against Britton (accounting for Britton’s own splits) comes out to .314, while Bregman’s is .372. Given that the Yankees gave up so little win expectancy by putting Bregman on, the back-of-the-envelope math makes the decision obvious. The team would need to face a batter who projected to be at least 31 points of wOBA worse than Bregman to make the decision worth it, and Gurriel is 58 points worse. Good intentional walk!

There was only a moment during Game 4 of the NLCS on Tuesday when it felt as though whatever weird hex had enveloped the last seven years of Washington Nationals baseball might be ready to rear its ugly head once more. It was in the top of the eighth inning, when the St. Louis Cardinals loaded the bases with two outs and a three-run deficit. Washington had once led 7-0, but a rally by the Cardinals in the middle innings more than halved that advantage, and now, they actually had the tying run on base. It was on this same field, seven years ago, that the Cardinals had erased a 6-0 deficit to win a do-or-die Game 5 in the NLDS, and it was on this same field that the Nationals’ bullpen had let so many games slip away over the years. For a minute, one could see the narrative beginning to snap back into place. But then, Daniel Hudson forced Matt Carpenter to roll over on a groundball to second base, and Washington inched closer to one of the most dominant series victories in recent memory.

The Nationals defeated St. Louis by a score of 7-4 on Tuesday, completing a four-game sweep that secured the first pennant in franchise history. They outscored the Cardinals 20-6 in the series, with their pitchers yielding just five earned runs, seven walks, and one home run while striking out 48 in 36 innings. That works out to a 1.25 ERA, 12 K/9, 1.75 BB/9, and 0.25 HR/9 in the four biggest games of their season. It was the first NLCS sweep since the Mets defeated the Cubs in 2015, and just the third NLCS sweep of the last 24 years.

Patrick Corbin was the latest Washington starting pitcher to baffle Cardinals hitters. He struck out the side in the first inning, and went on to fan seven of the first nine batters he faced and a total of 12 in just five innings of work. He also allowed three walks, along with four runs on four hits. Corbin got swings and misses on 24 of the 94 pitches he threw, giving him a whiff rate of 25.5% that stands as the highest he’s ever registered in a start in his career according to Baseball Savant. Of those 24 whiffs, 16 came against his slider, which he threw a total of 42 times. Just one of those sliders was put into play by a Cardinals batter. Read the rest of this entry »

With the Cardinals’ offense held to two runs across the first three games of the NLCS against the Nationals, the team has dug themselves a hole. The odds of the Cardinals winning four straight games aren’t high; our standard odds give the Cardinals a 3.1% chance at taking the series with ZiPS’ method going a bit higher at 4.9%. Winning four games in a row against a good opponent isn’t impossible. Just a few weeks ago the Cardinals pulled off a four-game sweep to solidify their playoff position. Back in April, the team completed a four-game sweep of the Dodgers and later that month, they won the first three of a four-game set against the Nationals. If Cardinals were to do the same now, they would force a Game 7. But that St. Louis has done something similar doesn’t change the current situation, which is dire, and the team isn’t helped by the fact that they have to turn to their fourth-best pitcher tonight when a loss ends the season.

Tonight’s start isn’t Dakota Hudson’s first with the Cardinals facing elimination. Just a week ago, he took the mound with St. Louis down two games to one against Atlanta. Hudson lasted four and two-thirds innings and gave up four runs, though three of those runs were the product of poor defensive play. The Cardinals eventually rallied to win that game in 10 innings and then blew the Braves out in Atlanta to advance to the NLCS. Hudson’s performance in that start was fairly typical for him, with a low number of strikeouts, a couple of walks, and what would have been a low run total if the normally stout Cardinals defense had supported him.

Tonight’s game isn’t likely to turn on the performance Hudson provides, given the offensive offensive performances by St. Louis so far, but if the Cardinals are going to extend the series, it’s important that their starter keep them in the game. Hudson’s profile is unique and he’s been a near-perfect fit for the Cardinals this season. Looking at various WAR metrics, his 1.0 WAR indicates mediocrity. If we were to use WAR based on his .335 xwOBA, we’d see a similar result. Over at Baseball-Reference, he’s put up a 2.2 WAR, a roughly average pitcher. Baseball Prospectus sees a similar 2.4 figure.

Where Hudson separates himself from that mediocrity is in our RA9-WAR, where he has put up a 3.4 mark this season, which ranks 18th in the National League. Given what all the other WAR metrics say about Hudson, along with his low strikeout totals and high walk rate, it’s not a stretch to say that his 3.4 RA9-WAR inflates his talents a bit. However, it also wouldn’t be a stretch to say that Hudson combined with the Cardinals defense is one of the 20-best pitchers in the NL. Hudson couldn’t move to Queens with the Mets infield defense and be that pitcher, but with Kolten Wong, Paul DeJong, Paul Goldschmidt and Tommy Edman (or Matt Carpenter), he gets the results of a good pitcher. Hudson has one elite skill, and he and the Cardinals combine to get outs at a very high rate. Read the rest of this entry »
