What causes teams to succeed in the playoffs? This is one of the debates in baseball most ridden with conventional wisdom, folksy tales, and grand assertions. Some claim that teams need to have playoff experience. Others focus on clutch performance, which usually coincides with whatever the person wishes to argue. A common argument, more cloaked in the language of reasonableness, is that teams that are more reliant on home runs than other ways of scoring underperform in the postseason. There are myriad reasons given for why some teams end up winning October, and most of them can tested for accuracy based on baseball history. I did a piece last year that looked at dozens of different team variables, and most of the explanations meant bupkis.

That doesn’t necessarily mean we throw our hands in the air and just assume teams are equally as good as they are in the regular season and go with that. There are significant structural differences between postseason and regular-season play simply due to the number of games and the increased number of off-days. Regular-season winning percentage is one of the few good predictors of postseason success; projections do even better. When I change the methodology in the ZiPS projections to focus more on a team’s frontline talent and the exact matchups and less on important regular-season things like depth, team strength becomes significantly more predictive of postseason success.

One of the best recent examples of this is the Nationals in 2019. Despite the 13-win regular-season advantage of the Dodgers, ZiPS projected their NLDS as a coin flip on the strength of the Nats being able to stuff so much of their team’s value into players who would be on the field. That was a projection that got a lot of pushback, but in the end, Washington won the World Series, basically riding the top of the rotation, a few really good hitters, and the two or three relievers that Dave Martinez could actually trust.

You can understand the excitement around the Phillies at the moment; this is the defending National League champion, on the verge of clinching a home playoff series, with tons of nationally recognizable players.

But no amount of juice can replace the excitement of the new, because the most interesting player on this team is a relief pitcher who made his MLB debut on Sunday. In case you weren’t aware of him already, here’s Orion Kerkering.

What a moment for Orion Kerkering. ? pic.twitter.com/OoT5nsb9GV

If you follow either the Phillies or the minor leagues in the northeastern U.S., you’ve been waiting for this moment for months. If not, you’re probably wondering why anyone should care about a pitcher who’s clearly named after a spacefaring outlaw whose rakish charm and rough exterior belie the fact that deep down he has a heart of gold.

The Phillies are still paying a reputational penalty for running out some of the worst bullpens in MLB history in the late 2010s, but this current crop of relievers is perfectly serviceable — perhaps even more than that once Rob Thomson figures out how he wants to use his various swingmen in the playoffs. Kerkering has the potential to be the best of the bunch. After 12 pitches at the major league level, he might be that now. Read the rest of this entry »

With apologies to Matt Olson, Freddie Freeman, and Corbin Carroll, the race for the NL MVP Award has essentially boiled down to two players: Ronald Acuña Jr. and Mookie Betts. It’s an incredibly close one, with the pair producing such similar batting lines that they’re tied for the NL lead with a 169 wRC+. Betts has the edge in both the FanGraphs and Baseball Reference versions of WAR, Acuña has the edge in several counting stats, and each player has added some unique additional flavors into the mix.

For Acuña, those largely center around his prolific baserunning. Aided by the new rules — particularly the limits on pickoff throws — and unhindered by a drop in sprint speed in the wake of his 2021 ACL tear, he’s stolen 68 bases, the highest total in the majors since 2010. With his 40th homer coming against the Nationals on Friday, he has just the fifth 40–40 season ever, and now the most steals of any player in that club, surpassing Alex Rodriguez’s 46 from 1998 (to go with 42 homers). With one week remaining, he needs two steals to become the first player ever to combine 40 homers and 70 steals in the same campaign, in what’s arguably the greatest power-speed combo season anybody has seen.

There’s certainly value to such an accomplishment, though we’re entering the realm of intangibility. We’re already crediting the value of his homers and steals within the context of the rest of his offensive stat line, but things like wOBA, wRC+, and WAR don’t tell us how much to care about a player reaching round-numbered milestones like these, even if they’re without precedent. Even less clear-cut is the attempt to examine the extent to which Acuña’s baserunning has helped his teammates, mainly by giving them more fastballs to hit. Colleague Esteban Rivera established that yes, players do see more fastballs when he’s on first, but their performances against those fastballs wasn’t uniformly better. “Acuña is most likely helping his teammates see more heaters,” he concluded. “What they do with those pitches, though, is completely up to them.”

Betts isn’t without his own cool counting stat achievements. His two-run double off Ross Stripling on Saturday night gave him 105 RBIs out of the leadoff spot, a record (Acuña is third at 101). Meanwhile, he’s hit 12 leadoff homers, one shy of the single-season record set by Alfonso Soriano in 2003, and his career-high 39 homers are two shy of the post-World War II record for the most by a player listed at 5-foot-9 or shorter, currently held by Roy Campanella. But bigger (if more difficult to measure) impact he’s made is with his sudden burst of Zobristian versatility: In the wake of Gavin Lux tearing his right ACL in late February, Betts has started 69 games in the infield — 56 at second base and another 12 at shortstop — in his most infield play in nearly a decade.

Hao-Yu Lee will be one of eight Detroit Tigers prospects participating in the forthcoming Arizona Fall League, and while he doesn’t possess the highest profile of the bunch, he does have the most-traveled backstory. Acquired from the Philadelphia Phillies at the trade deadline in exchange for Michael Lorenzen, the 20-year-old infielder hails from Taiwan and began dreaming of playing professionally in the United States at age 16 after a strong performance in a U-18 tournament, in Korea. Two years earlier he’d excelled in a tournament that took place 15-plus miles southwest of Comerica Park.

The Phillies signed Hao-Yu in June 2021—the Cincinnati Reds and Tampa Bay Rays were among the other MLB teams that had expressed interest — once he’d finished high school. No. 8 on our Phillies Top Prospects list with a 40+ FV coming into this season, he slashed .273/.362/.399 before going on the shelf with a quad strain in mid-August. He ended up playing in just eight games for the High-A West Michigan Whitecaps before missing the duration of the campaign.

The first big-league game Hao-Yu attended was in 2017 when he was competing in the Junior League World Series, which is held annually in Taylor, Michigan. He doesn’t remember if the Tigers won that day, but he does recall his first impression of Comerica Park. “I told my teammates that I was going to play here someday,” the confident youngster said of the experience.

He also remembers the tournament, and for good reason. Not only did Taoyuan, Taiwan capture the international bracket, they went on to beat Kennett Square, Pennsylvania in the finals. Moreover, Hao-Yu “raked that tournament; five games, five homers!” Read the rest of this entry »

After a week off to recharge my batteries — and watch other sports, gasp — it’s time for another installment of five things that caught my eye in baseball this week. Honestly, this list is almost superfluous at this time of year. The standings are so jammed together that half the games in baseball have playoff implications. Teams are getting hot at the right time or collapsing down the stretch in equal measure. Still, you can’t watch everything, so here are some delightful moments you might have missed.

1. Legends, in the Fall
It’s been a rough year for Adam Wainwright. He has put up by far the worst season of his career — a 7.40 ERA says all you really need to know about it — and the Cardinals have collapsed from the perpetual contention he enjoyed for the vast majority of his career. They’ve seemingly played more meaningless games this year than in Wainwright’s entire previous time with the club. Read the rest of this entry »

It feels like the Rays have been trying to ditch Tropicana Field since they got there, and apparently it’s finally going to happen. The Royals are likewise pursuing plans to build a replacement for Kauffman Stadium, though the club announced Wednesday that the planned reveal of a new ballpark site was being postponed for the time being.

Both clubs want to replace their aging, arguably obsolete concrete bowls with something more modern — more glitzy. The unspoken promise is that the Royals and Rays — two small-market teams that ranked 25th and 27th in payroll this season, respectively — would turn their new taxpayer-funded playgrounds into an economic engine that would not only boost community welfare but also allow the team to compete economically with the Yankees, Dodgers, and so forth.

We all know this is bunk. Read the rest of this entry »

Baseball players who eschew the typical conventions of major league success hold a special place in my heart. As much as we sit in awe of those gifted with the imposing stature of an Aaron Judge or a Giancarlo Stanton, there’s something particularly appealing about the guys who seemingly have to fight to compete in the same league and manage to find a way to do so. One of the wonders of a sport like baseball is that there are myriad ways to contribute – as fans, it’s fun to marvel at those who get creative.

On a Cincinnati Reds roster full of pleasant surprises, TJ Friedl doesn’t stand out so much as he blends in. At 28 years old, he’s one of the oldest regulars in an exceptionally young lineup, this despite being in his first full season in the big leagues. Depending on how you set the plate appearance threshold, he’s not the Reds’ best hitter by any individual metric, nor is he the fastest runner or the flashiest defender – there’s an ultra-athletic 21-year-old phenom with the league’s fastest sprint speed and strongest infield arm that takes those distinctions. But by making his presence felt at the plate, on the bases, and in the field day in and day out, Friedl has managed to be the most productive player by WAR on a team that sits one game out of a playoff spot on September 21. That’s a generous way to frame his 3.4-WAR season, but it’s also an accurate one – Friedl has been a versatile everyday contributor, and there’s a case to be made that he’s been the Reds’ most important player in what has been a pretty important year for the franchise.

The Orioles have a tight grip on the AL East race. With time running out on the season, they have a 2.5 game lead on the Rays with the tiebreaker in hand; the division title comes with homefield advantage throughout the AL playoffs. Their +127 run differential is the third-best in the AL. So then why oh why do we at FanGraphs think they only have a 5.5% chance of winning the World Series, worse than the Astros and Rays and just ahead of the Blue Jays and Mariners?

It’s happened two years in a row now. FanGraphs keeps doubting the Orioles, and they keep winning. But don’t you worry, disgruntled O’s fans. As the resident Orioles believer – I picked them to win their division before the season, even if that was mostly a statement that they were underrated rather than a sincere belief that they were the best team in the East – I’m here to dig through the madness and see what’s going on.

First things first, in these “why don’t the odds believe in my team?” articles, it’s always good to walk through how the odds work. They’re quite straightforward, though straightforward isn’t the same thing as simple. We start at the player level, averaging the Steamer and ZiPS projections to come up with projections for every player in baseball. Then we manually build a depth chart for each team. From there, we stitch those pieces together to come up with team-level offensive, defensive, and pitching projections. We plug those into the BaseRuns formula and get projections of how many runs per game each team will score and allow, then convert those to expected winning percentages using Pythagenpat expectation.

Austin Hays knows his numbers. More importantly, he understands the process behind his production. He’s also having a career-best year: the 28-year-old outfielder has a 117 wRC+ to go with 36 doubles, 16 home runs, and a .283/.330/.462 slash line as a rock-solid contributor for a postseason-bound Baltimore Orioles team with the most wins in the American League. Overshadowed by young stars like Gunnar Henderson and Adley Rutschman, he is nonetheless an important piece of the puzzle.

The personable Port Orange, Florida product hasn’t revamped his approach this season, but he has tweaked it in search of more thump. Hays explained how when the Orioles visited Fenway Park earlier this month.

David Laurila: When I brought it up yesterday, you told me you were aware that many of your 2023 counting stats are almost identical to what they were at the end of last year. What percentage of guys in this clubhouse would you say keep up with their numbers?

Austin Hays: “I think it’s probably about half and half. There are guys who like to follow where they’re at, follow what they’re doing, and there are others who just like to look at the end of the season. I find numbers interesting, so I like to look at my own, and other people’s numbers as well. It’s something I’ve always been interested in.”

Laurila: You’re in the process of passing some personal milestones. Which of your numbers do you care the most about?

Hays: “Doubles is a big one for me, because that seems to be the thing that helps me out the most with my power numbers. I don’t hit a ton of home runs, so the more doubles I can hit, the higher my slug and my OPS can be. You can get doubles in so many different ways, too. It’s kind of a hustle stat in a way. If you can accumulate five to 10 hustle doubles by going hard out of the box throughout the season, they’ll start to add up, That’s thing I’m probably trying to boost up the most.” Read the rest of this entry »

Last week, David Laurila asked me an interesting question. He’d been talking baseball with some baseball players – it’s true, we really do have great jobs – and the conversation landed on Josh Hader. That got Laurila thinking about Hader’s similarities to Spencer Strider. The crux of the discussion: Would Hader have ended up as a lefty version of Strider if, after appearing in the major leagues as a reliever, he’d transitioned back to the starting role he held in the minors?

I love questions like this. They’re fun to research, and I also feel no pressure to reach a definitive answer. Would Hader have ended up as a great starter? It’s clearly unknowable. That gives me a lot more latitude to speculate. In addition, this question isn’t just about Hader. It’s about whether future pitchers with Hader-esque profiles make more sense as starters or in the bullpen. No wrong answers and broad implications? Sign me up.

First things first, let’s talk about what it means to look like Strider as a starter. Strider has two standout pitches, but it’s really one standout pitch and a capable understudy. His fastball explodes through the top of the zone and screws hitters into the ground. It’s not so much the velocity – though that doesn’t hurt – but the shape and release point that combine to bamboozle opposing hitters. Read the rest of this entry »
