Quick Sunday update. The Yankees lost on Saturday, furthering the potential for chaos, and the four-way tie is an increased possibility, at 6.5%. The chances of bonus baseball overall now stand at 57.6%. Good news for us and good news for the Rays, who will play one of these four teams later this week. It’s not something that’s captured in projections, but it’s interesting that if the Rays go full B-team, it reduces the chances of a tie, and as a result, a slight reprieve for the team they eventually play. Jameson Taillon is back in as the starter and Joan Adon looks to be Washington’s starter, which is to Boston’s benefit according to the projections.

The NL West remains unresolved, but simple: if the Dodgers win and the Giants lose, they play a tiebreak game. ZiPS has a 19.8% chance of a tiebreaker game, with the overall division as San Franciso 90.0%, Los Angeles 10.0%. Freddy Peralta is being held back for the playoffs with Brett Anderson going today. It makes sense too; it’s in Milwaukee’s interest to leave one of these teams more susceptible to getting knocked out of the playoffs by the Cardinals later this week.

American League Wild Card

The Yankees and their bats were largely quiet against the Rays on Friday, but they still basically control their own destiny as the team in the first Wild Card spot, albeit the one with by far the toughest opposition. The Blue Jays fended off a late-inning Baltimore rally and held on to the win, but the Red Sox winning was just as damaging to Toronto’s playoff hopes as the Jays’ win was helpful. Toronto’s still one-in-five to make the postseason, but needs some help now; since the Blue Jays are already assumed to be strongly favored to beat the Orioles, they get an even larger boost from a Nationals win.

The Mariners are entering the final weekend of the regular season with their best shot since 2016 at breaking their infamous postseason drought, having gone 18–8 in September and won 11 of their last 13 games after losing a crucial series to the Red Sox mid-month. Earlier this morning, Jay Jaffe took a look at the bigger picture for the Mariners, their negative run differential, and the historic positive turn of their playoff odds. But this climb up the standings wouldn’t have been possible if it weren’t for some unheralded performances by a number of players on their roster.

From a season-long perspective, the Mariners’ offense has been lackluster, with a wRC+ of 94, ranking tenth in the American League. That went up to 103 in September, but the driving force behind the improved offense has been excellent performance in tight situations. Seattle has the most clutch offense in recorded MLB history (WPA records only go back to 1974), which goes a long way toward explaining the team’s 33–18 record in one-run games this year.

Clutch hitting can take a team far, but it’s not something that can be counted on every night. Luckily, the core of the Mariners’ lineup started hitting extremely well during the final month:

After shuffling through a number of early-season contributors, the lineup stabilized after the All-Star break — something that coincided with Kelenic’s second call-up from Triple-A after his rough debut in May. The hits didn’t start falling immediately after his return to the majors; from July 16 through the end of August, he posted a .181/.263/.315 line (a 65 wRC+) with a 30.5% strikeout rate. But something clicked once the calendar turned over to September, with Kelenic hitting .242/.321/.537, good for a 135 wRC+. His strikeout rate dropped to 25.5%, he launched seven home runs, and more than half of his hits went for extra bases.

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. Read the rest of this entry »

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 »

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.

These are notes on prospects from Eric Longenhagen. Read previous installments of the Daily Prospect Notes here.

Games on 9/12

Mason Fox, RHP, San Diego Padres
Level & Affiliate: Double-A San Antonio Age: 21 Org Rank: 38 FV: 35+
Line: 1 IP, 3 K

Notes
Fox’s previously dominant fastball (he had a 0.55 ERA and 0.98 WHIP in 2019, mostly in short-season ball) wasn’t as nasty during the spring. Sitting in the low-90s, he struggled and was shut down, and was put on the Development List for most of July and August. Back for about three weeks now, his fastball velocity has more often been in the 93-95 range again, though his curveball still lacks bat-missing power and depth. Because 2021 is his roster evaluation year (either he’s put on the 40-man or subject to the Rule 5 Draft in December) and because he’s thrown so few innings so far this season, the Arizona Fall league is perhaps a logical assignment for Fox and the Padres.

Jackson Rutledge, RHP, Washington Nationals
Level & Affiliate: Low-A Fredricksburg Age: 22 Org Rank: 5 FV: 45+
Line: 4 IP, 3 H, 1 BB, 1 R, 4 K

Notes
Speaking of other potential Fall League candidates (I’m drawing logical conclusions here, not reporting anything or leaking dope), Jackson Rutledge has struggled to take the ball every fifth day because of an early-season shoulder injury, and more recently, recurring blister issues. Sunday was Rutledge’s third blister-free start since his most recent activation. He’s sitting in the 94-98 range since returning, with his stuff intact coming off those dreaded shoulder issues. Obviously context is important here (it’s not as if Rutledge has gone every fifth day all year and is sitting 94-98), but that’s an encouraging sign for his health. Having amassed just 32 innings this season, Rutledge is a prime Fall League candidate. Read the rest of this entry »

In the days leading up to the trade deadline, Jarred Kelenic earned himself a mention in Jay Jaffe’s corner outfield replacement-level killers, a series that analyzes the players who are dragging down contending teams. The idea is to identify positions of need for potential trades to come, but Kelenic’s struggles in the majors weren’t going to force the team to make a deal. Instead, as Jay put it, “this should probably be a sink-or-swim situation unless he’s totally overwhelmed.”

Kelenic has already been in the spotlight because of the Mariners gaming his service time; his performance since his promotion has put him back in it. He got the call on May 13, but simply didn’t hit: In his first 23 games over a total of 92 plate appearances, he slashed .096/.185/.193. He collected just eight hits total and had come up empty in his last 44 plate appearances when the Mariners optioned him back to Triple-A in early June.

After a successful stint at Tacoma — a 137 wRC+ — Kelenic was brought back to Seattle. This time around, the results have been a bit better, but they’re still ugly overall, as he’s gone from a 10 wRC+ in that first stint to a .181/.263/.315 line and 65 wRC+ since his second promotion. Through Tuesday’s action, he’s up to a 45 wRC+ and -1.1 WAR in 64 games:

Even with the improved numbers since his return from Triple-A, Kelenic is still running the 11th-lowest wRC+ among qualified hitters in that time. He’s still not hitting well. But while there may not be one answer for why he is struggling, I believe that there’s a huge plate discipline problem that isn’t entirely captured in the walk and strikeout rates alone.

One of the biggest reasons the Mariners have stuck around the fringes of the AL wild card race despite a -60 run differential has been the collective performance of their bullpen. Kendall Graveman had established himself as a bonafide relief ace before being traded to the Astros in late-July, and Drew Steckenrider has revived his career after falling apart in Miami two years ago. But equally unexpected, and perhaps the biggest reason Seattle felt comfortable dealing Graveman at all, has been the fantastic season put together by its other breakout relief ace: Paul Sewald.

Drafted as a reliever by the Mets in the 10th round of the 2012 draft, Sewald came with two years of college experience under his belt at the University of San Diego and quickly moved through the farm system. He reached the majors in 2017 and made 125 appearances out of the bullpen through 2020, but outside of a 23.5% strikeout rate that was just a hair above league average, he was mostly forgettable as a Met; across 147.1 innings in New York, he posted a 5.50 ERA. He was non-tendered this past offseason and signed a minor-league contract with the Mariners in January.

Even though Sewald wasn’t able to make the major league roster out of spring training, he has thrived in Seattle. He was called up on May 13, the same day Jarred Kelenic and Logan Gilbert made their debuts, and while his return to the majors was much less heralded than those two top prospects, he’s arguably been more important to the Mariners this season than either. He’s upped his strikeout rate to 40.3% in 2021, the fifth highest rate among all qualified relievers, and all those strikeouts have helped him drop his FIP to just 1.95. In just 45.1 innings, he’s more than doubled his total career WAR.

Michael Ajeto of Lookout Landing was one of the first to write about Sewald’s breakout, but the reasons for his improvement are tough to spot on the surface. He’s simplified his pitch mix a bit, cutting out his rarely thrown changeup and increasing the usage of his slider to make him a two-pitch pitcher:

Both the fastball and slider are returning better-than-ever results, with the latter generating a 38.6% whiff rate and a .270 wOBA against. But as good as his breaking ball has been, the four-seam fastball has been even better. Its whiff rate is up to 35.3%, the 12th-highest mark among all four-seam fastballs thrown at least 100 times this year, and it boasts the 12th-highest CSW% (35.7) in that group.
