American League Wild Card

The Yankees have now reached the point where a win nearly clinches a playoff spot, though it doesn’t make one a mathematical certainty. With one more win, the Mariners and the Red Sox would both have to sweep their weekend series and the Yankees would have to lose out in the tiebreaker in order for New York to miss the playoffs. Similar to our probables grid, I’ve tentatively put in a short outing for Luis Severino on Sunday. The Yankees have been mum about their starter plans for that game, and as the team most likely to cement the top Wild Card spot before Sunday, they could also go total slop time so that they have as much strength as possible before next Tuesday’s play-in.

This is the fifth installment of this year’s Team Entropy series, my recurring look not only at the races for the remaining playoff spots but the potential for end-of-season chaos in the form of down-to-the-wire suspense and even tiebreakers. Ideally, we want more ties than the men’s department at Macy’s. If you’re new to this, please read the introduction here.

The Mariners haven’t reached the postseason since 2001, and all season long, our Playoff Odds have strongly suggested that their drought — the majors’ longest active one — will continue. But as we head into the final weekend of the 2021 season, they’re on a 10-1 tear that has interjected them right into the thick of an American League Wild Card race with a decided East Coast bias. With the Yankees sweeping the Red Sox in Boston and then taking two out of three from the Blue Jays in Toronto while the Red Sox somehow dropped two out of three to the Orioles in Baltimore, we now have four teams separated by three games from top to bottom, with just three to play for each:

This is not a drill! I’ll get to the mechanics of how this will be sorted out soon enough, but first, I’m taking the opportunity to spotlight the Mariners’ unlikely run and the trends they’re up against. This isn’t a dive into individual performances; elsewhere on FanGraphs today, Jake Mailhot has a closer look at what’s fueled their September run. Here I’m looking at the bigger picture. But first, an illustration of the Mariners’ Playoff Odds over the course of the season:

It’s been awhile since the Mariners were anywhere close to this position. While they went 89-73 just three years ago before slipping below .500 in both 2019 (68-94) and ’20 (27-33), that ’18 squad fell eight games short in the AL Wild Card race and finished 14 games behind the Astros in the AL West race. They did finish three games back in the AL Wild Card race in 2016, going 86-76 while both the Orioles and Blue Jays went 89-73, but they were a distant nine games behind the Rangers in the AL West. Not since 2003, when they went 93-69 in Lou Piniella’s final year at the helm, have they come as close by both routes to the postseason; that year, they finished three games behind the A’s in the division race and two behind the Red Sox in the AL Wild Card. And not since that 2001 team set a modern record with 116 wins have they qualified for the playoffs. Read the rest of this entry »

American League Wild Card

Seattle beat Oakland on Wednesday, sweeping the series and knocking the A’s out of playoff contention. As such, Oakland is no longer a participant in these charts. The Blue Jays won the second game of their series against the Yankees, preventing them from falling to fourth in the playoff probabilities, behind the Mariners. We’ll be a lot closer to knowing who makes the playoffs in the AL after tonight’s games, as those contests — the last contender vs. contender matchup, as well as the biggest creampuff game for a contender — are the two highest leverage games remaining.

A few days ago, I wrote about projections and the stretch run, using ZiPS to project each individual game and estimate its relative importance for the final standings. With just a few games remaining, most have the potential to drastically swing the disposition of the race. For example, the Mariners saw their playoff probability quintuple with last night’s win over the A’s! Let’s break down the latest and greatest.

AL Wild Card

This one is still very wide open, with the main difference from 48 hours ago being that the Mariners have pushed the A’s to the brink of elimination. Oakland can still make the playoffs, but the path is narrow and would require Oakland to win three or four games while Toronto, Boston, and Seattle mostly lose, and then perhaps survive a tiebreaker. Oakland can no longer catch the Yankees, so it’s in the A’s interest for the Yankees to finish a sweep of the Jays: Read the rest of this entry »

The Learning and Developing a Pitch series returned this summer after being on hiatus last year due to the pandemic. Each week, we’re hearing from pitchers on a notable weapon in their arsenal. Today’s installment features Gerrit Cole on his curveball and Austin Davis on his slider.

Gerrit Cole, New York Yankees

“A.J. Burnett taught Charlie Morton and me the grip when we were in Pittsburgh. He would take me in the cage and do drills with me that his dad would do with him when he was a kid. The curveball is something he’s basically had since the first time he started playing catch, which is different than me, but similar to Jameson [Taillon]. So I had to learn it. He showed me the grip, showed me the drills, and kind of described what he was feeling and what he was looking for. This was in 2012, in spring training. Then in 2013, in the big leagues, we worked on it a lot.

“I’d been pretty much slider only. I had tried a bigger curveball. I’d tried to make the slider bigger. I’d tried to throw a shorter cutter. But I never really had a true downer breaking ball. At first, I incorporated it in Pittsburgh [and] a lot was changing speeds. It’s kind of developed a little bit beyond just that.

“One of [the drills] was with an L screen. We played catch in the cage a few times. He’d back me up to 50-55 [feet] — just in front of the mound — and I would play catch with the curveball. Then he would slide the L screen over. The objective was to throw the curveball and make it go right over the shorter portion of the L screen. It would get to the correct height at the finish. We practiced that a lot. Read the rest of this entry »

9/28 Late Morning Update

`

The original data and methodology are below.
==
We’ve reached the final week of the 2021 regular season, and for fans of high-intensity, stretch-drive baseball — a group I think we can refer to as “everyone” — there’s still quite a lot to play for. Only five of the 10 playoff spots are claimed, with two of those five teams in a battle for a division title. And since there are just a handful of games left to play, we can move the ZiPS projections from the macro to the micro. In April, it’s always hard to project specific pitcher matchups, but with a week left to go in the season, it’s a more reasonable task of extrapolation. As a result, that allows me to adapt the ZiPS model into a game-by-game projection of the final week of the season for the relevant teams.

I’ve focused on three of the playoff spots, the two AL wild cards, and the NL East, along with the division versus wild card battle in the NL West. The Astros can still technically lose the division to the Mariners (one-in-about-1,800) or the Athletics (one-in-about-2,150), and the Cardinals could still have an epic collapse in which they lose six, the Reds win six, and they lose the tiebreaker (one-in-about-3,300). These could also become mathematical impossibilities quickly; if they become plausible rather than proverbial lottery tickets, I’ll update with the data.

Let’s start with the easy races.

NL East

The Braves enter the final week with a 2 1/2-game lead in the division but three games remaining against the Phillies. Their schedules are similar in strength, with Atlanta getting home games and Philadelphia on the road, something that’s largely canceled out by the former getting the slightly harder opponent (the Mets versus the Marlins). The edge comes from the cushion.

With the edge in the standings, ZiPS projects just over a four-in-five chance that the Braves will not have to play the Rockies in a makeup game on Monday. Overall, the Braves win the division 87.7% of the time without the makeup game, and the Phillies stick the Braves in at least a 1 1/2-game hole 1.0% of the time.

High-performing under-the-radar prospects have been featured frequently in this space over recent months, and Brandon Phaadt fits that description to a T. Unranked coming into the season, the 22-year-old right-hander in the Arizona Diamondbacks system posted a 3.21 ERA while fanning 160 batters in 131-and-two-thirds innings. Moreover, he did so while pitching at three levels —Pfaadt’s last six starts came with Double-A Amarillo — as a 2020 fifth-round pick out of a DII school.

The Bellarmine University product pushed back slightly when I suggested that his auspicious performance came out of the blue.

“I guess it did in some people’s eyes,” said Pfaadt. “But I knew I had it all along. I had a long offseason to train, and I also think it was really important that I was able to work with three different pitching coaches this year. I got feedback from all three, and was able to take bits and pieces from each of them.”

Asked for examples, Pfaadt told me that Barry Enright (Low-A Visalia) was more mechanics-based and worked with him on the consistency of his delivery, while Shane Loux (High-A Hillsboro) was more about pitchability. At Amarillo, Doug Drabek provided an effective combination of old-school and new-school acumen. As Pfaadt put it, Drabek “knows what worked back then, and what works now.”

Pitch design didn’t play a role. Read the rest of this entry »

Given his rise from dark horse to odds-on NL MVP favorite, it’s not a huge surprise that Bryce Harper has been the best hitter in baseball since August 1. Through Sunday’s action, he slashed.346/.464/.795 in 198 plate appearances, good for a 216 wRC+. That performance has catapulted him to the very top of the race, moving ahead of Fernando Tatis Jr. in betting markets as of Monday. A lot thus has been said about Harper, but much less has been written about the second-best hitter over this stretch (among the 251 players to amass at least 100 plate appearances). That hitter, as you could probably guess from this piece’s title, is Red Sox infielder Bobby Dalbec, whose .316/.409/.737 line nearly matches Harper’s, though it has come without the associated fanfare.

That’s understandable given Dalbec’s start to the season. Unlike Harper, who posted very good numbers before his recent stretch of sheer fire, Dalbec nearly found himself without a spot on Boston’s roster following the team’s trade for Kyle Schwarber. Through July 31, Dalbec was slashing just .216/.260/.399, with a 4.4% walk rate, a 37.5% strikeout rate, and 11 homers in 296 trips to the dish. That, coupled with less-than-stellar defense (it’s still rated as a negative), gave the Red Sox every reason to option him to Triple-A. Indeed, as Peter Abraham at The Boston Globe wrote on September 12, “That Schwarber was on the injured list at the time may have been what kept Dalbec on the roster.”

The hot start to Dalbec’s career last season — a 152 wRC+ and eight homers in just 92 plate appearances — seemed unsustainable given the small sample size, 42% strikeout rate, and .394 BABIP. As a result, ZiPS projected him for a 91 wRC+ this season, though Steamer was more bullish at 103. The poor start and the hot stretch since have resulted in season stats — a .245/.306/.497 slashline and 111 wRC+ — roughly in line with what I’d peg as his true talent level.

Tanner Houck’s signature pitch is a sweeping slider. The 25-year-old Boston Red Sox right-hander has gone to it 35.5% of the time this season, and with good results. There is little question that the offering is the most lethal weapon in his arsenal. That said, it’s arguably not his most important pitch going forward — particularly if his future is in the starting rotation, and not out of the bullpen.

Bedeviled by an inability to master a conventional changeup, Houck began learning a split-finger fastball last year. The pitch remains something of a work-in-progress, yet he’s begun throwing it more frequently. Houck’s splitter usage is up to 7.5% on the season, a percentage that promises to rise if he can fine-tune it further. Four years after he was drafted 24th overall out of the University of Missouri, Houck is hoping that his newest pitch will take him to the next level.

———

Tanner Houck: “I had trouble throwing a changeup. I would constantly baby it — I would get on the side of it and just push it — so it was really inconsistent. They came to me and said, ‘Hey, we want you to throw a splitter.’ This was in spring training 2020, four days before we got canceled. It was a heck of a time to start learning a new pitch.

“They wanted me to keep working on the change, but also attempt to throw the splitter, and I was like, ‘OK, fine; I’ll give it a shot.’ I threw a bullpen the next day, and for every five, maybe one of them wasn’t too bad. At that time it was still 90-93 [mph]; it was essentially just a little bit worse of a two-seam. But I didn’t think anything of it. I was like, ‘This is literally day one of throwing this pitch, so it’s not a big deal.’ Then COVID happens, so I go home. Read the rest of this entry »

It didn’t explicitly come up in the Effectively Wild podcast spot I did highlighting this year’s Team Entropy series, but one reason why the Wild Card races that I covered in my second installment early this week are so wild — with five teams chasing two spots in the AL, and five more chasing one spot in the NL — is a handful of prominent collapses. The Mets, Padres, and Red Sox all spent a good chunk of the season occupying playoff positions, with New York and Boston occupying the top spots in their respective divisions for more days than any of their competitors. Yet all three teams could miss out on October baseball thanks to some of the most drastic first half-to-second-half drop-offs we’ve seen in recent years.

The Mets, despite a slew of injuries, led the NL East — at times with company in first place — for nearly four months, from April 13 to August 6, with a slight return after falling out of first that stretched the window to August 13. They somehow did that by posting winning records only in May (17-9) and July (14-13), and even after being overtaken, they remained within striking distance for about half of a dreadful August during which they went 9-19. Since the July 30 trade deadline, when they acquired Javier Báez but arguably didn’t do enough to bolster their rotation — a decision that was exacerbated by Jacob deGrom’s subsequent setback, which came to light almost immediately after the deadline passed — they’ve gone just 17-28. At this writing, they’re 72-75, 5 1/2 games behind the Braves in the NL East, and five behind the Cardinal for the second NL Wild Card spot, with cumulative playoff odds of 2.1%. I’m skeptical they’ll be relevant by the time I next cover Team Entropy.

The Red Sox had an on-and-off relationship with first place in the AL East, occupying at least a share of it from April 8 through May 23, and then again for most of a stretch that ran from June 19 through July 30. They’ve gone just 20-24 since the deadline passed, for the third-worst record in the AL; they did so while the Rays (29-14), Blue Jays (31-16), and Yankees (29-16) peeled off the AL’s top three records in that span. A wave of COVID infections has played a part, knocking 12 players — including Xander Bogaerts, Enrique Hernández, Chris Sale, and Matt Barnes — out of action since August 27; notably, the Red Sox are one of the six teams that has failed to reach the 85% vaccination threshold to loosen protocols, though the majority of those infected were vaccinated. They’re now 8 1/2 games back in the AL East, but occupying the second Wild Card spot, a percentage point behind the Blue Jays and half a game ahead of the Yankees, with Playoff Odds of 75.3%.

The Padres were projected to be one of the NL’s two best teams, albeit in a division occupied by the other one, the Dodgers. But while the defending champions have indeed been one of the top two, it’s been the Giants, not the Padres, who have provided their closest competition; San Diego has spent just 14 days in first place in the NL West. Even so, they spent nearly three-quarters of the season with Playoff Odds of 75% or better, but have gone just 16-25 since the deadline, and 10-21 since August 10. Having just won back-to-back games for the second time in the past five weeks, they’ve closed the gap behind the Giants to, uh, 18 1/2 games, but their Playoff Odds have dwindled to 32.0%.

As you can see, there’s a pretty wide spread when it comes to these three teams’ chances of playing October baseball, but each has fallen significantly from the spots they occupied earlier in the season. Depending on where I set the endpoints, their slumps might appear even more acute, which works for storytelling purposes, but is harder for comparative analysis. Since all three were riding rather high in early July, I decided to see how their declines in winning percentage from the first 81 games — a point the Padres reached on June 29, the Red Sox on June 30, and the Mets on July 4 — to the second compared to those of other teams in recent years.

As it turns out, the Padres’ drop from a .593 first-half winning percentage — the first 81 games of the season, not the uneven “halves” defined by proximity to the All-Star break — to a .422 second-half mark so far is the fourth-largest since 2012, the start of the two Wild Card team era; their dip ranked second until this two-game hot streak. Meanwhile those Red Sox and Mets rank among the dozen largest drop-offs, with yet another team from this year, one I hadn’t even considered for this piece given my apparent East Coast bias, in the top 20:

That’s not really a list you want to be on, judging by the minimal postseason impact of those teams. Obviously, we don’t yet know the playoff fates of the Padres, Red Sox, Mets (well, I think we know that one), and A’s (welcome to the party). Of the other 16 teams, seven made the playoffs; four won Wild Card games (the 2013 Pirates, ’15 Astros, ’16 Giants, and ’18 Yankees), but the only one that won a Division Series or a later round was the ’17 Astros, who, well, you know. Only one team with a drop-off of at least 87 points and a sub-.500 record in the second half won so much as a Wild Card game, namely the 2015 Astros.

Since the A’s turn up here, their arc is worth retracing as well. Despite being outscored in both April and May, strongly suggesting that they were playing over their heads, they climbed to the top of the AL West, and spent all but a single day of the next two months there, from April 20 to June 20. Despite their stellar June (17-9), an Astros team that had been lurking just behind them overtook them, and while the A’s were just 1 1/2 games back at the 81-game mark, and just 2 1/2 back at the 115-game mark (August 14) after some ups and downs, they’ve lost 18 of their last 29 and fallen seven games back. Their Playoff Odds peaked at 76.9% on June 18, and spent the next two months mostly in the 40-60% range, but they’ve plummeted from 62.5% on August 12 to just 4.3%.

So that’s two AL and two NL teams that have each taken rather dramatic tumbles this season. As you can see from the table above, it’s the second time within this span we’ve seen four teams from a single season take such falls; in 2018, the Yankees and Mariners both crumbled, as did the Phillies and Diamondbacks, with Philadelphia even sliding below .500 for the season to finish 80-82.

Not surprisingly, all four of these teams that have crashed in 2021 have underachieved relative to their Pythagenpat records during the second half. The Padres are the only ones who were underachieving during the season’s first half as well:

For the Padres, this has mainly been about the collapse of a rotation projected to be the majors’ best coming into the season; it’s been lit for a 5.52 ERA and 4.82 FIP in this second half. Yu Darvish has been battered for a 7.67 ERA and 5.74 FIP in 54 innings during this slide, that while landing on the injured list twice, for left hip tightness and lower back tightness. Ryan Weathers has completely collapsed (9.00 ERA, 7.55 FIP in 38.1 innings) after a promising beginning, Chris Paddack (5.74 ERA, 4.13 FIP in 42.1 innings) has had some bad luck, and even Joe Musgrove has regressed (3.79 ERA, 4.31 FIP). On the other hand, Blake Snell (3.03 ERA, 3.34 FIP) turned his season around, but a groin strain forced him out during the first inning of his September 12 start against the Dodgers. Adding insult to injury, the Padres reportedly were close to acquiring Max Scherzer at the deadline, only to watch as the Dodgers snatched him away, and he’s been brilliant. Scrapheap pickup Jake Arrieta? Not so much.

Run prevention has become a major issue for the Red Sox as well, with both the rotation and bullpen (4.42 ERA and 4.59 ERA, respectively) underperforming their FIPs by about four-tenths of a run. High-leverage guys such as Barnes, Adam Ottavino, and Hansel Robles have been particularly lousy. On the offensive side, the Sox have been a juggernaut, but while they’ve received a 100 wRC+ or better from nine out of the 11 players with 90 or more PA since July 1, Bogaerts (107 wRC+) and J.D. Martinez (108) haven’t been themselves, and rookie center fielder Jarren Duran (50) was over his head before landing on the COVID-19 injured list.

The Mets have continued to show holes on both sides of the ball. Offensively, Jeff McNeil (91 wRC+), James McCann (66), and Dominic Smith (56) have come up notably short even while the arrival of Báez (156), the return of J.D. Davis (118), and the upswing of Francisco Lindor (139) after a dreadful beginning to his season have helped; the last of those made the 36 games he missed due to an oblique strain a particularly big thumbs down. While late July additions Rich Hill and Trevor Williams have been pretty good, they don’t add up to a deGrom; meanwhile, the much-awaited arrival of Carlos Carrasco (5.59 ERA, 4.38 FIP) hasn’t really panned out, and Taijuan Walker (7.04 ERA, 6.90 FIP) has turned into a pumpkin. Key relievers such as Seth Lugo, Trevor May, Jeurys Familia, and Edwin Díaz have taken steps backwards of varying size at the wrong time as well.

By runs scored and allowed, the A’s have produced the same Pythagenpat winning percentages in both halves, but have gone from overachieving by 37 points to underachieving by 59 points, making for both the largest second-half shortfall and the largest overall swing relative to their expected record. The second-half fades of Sean Manaea and James Kaprielian and the frightening loss of Chris Bassitt (who’s still rehabbing his way back) have loomed large in the rotation. The bullpen — particularly Lou Trivino, Sergio Romo, and Yusmeiro Petit, three of the most four heavily-used relievers in the second half — has proven shaky as well.

For as much as these four teams have in common in terms of the severity of their second-half slides, and for as crowded as they’ve made the Wild Card races, it’s clear by now that the A’s and Mets are just hanging on, while the Red Sox are odds-on favorites to make it through, and the Padres are hardly out of it. Still, when the playoff slate is finally set, at least some of these teams will look back and wonder what might have been, and how they fell so far.
