After all the rumors and money and projections and Carlos Correa signing announcements (and un-announcements), here we are, back at 0-0, with every team having at least some technical level of hope for the 2023 season. Until today’s games start the process of turning projections into history, the season is a blank piece of paper or canvas, a fresh layer of snow without a hint of gray, a home improvement project before the moment you remember you barely know how to assemble an IKEA end table. Now before I get too wistful and start sounding like Paul Harvey or weird AI Vin Scully, let’s get down to business.

Since I am the owner, caretaker, and occasional messer-upper of the ZiPS projection system, that’s the system I used to run the 2023 season a million times. The methodology I’m using here isn’t identical to the one we use in our Projected Standings, meaning there will naturally be some important differences in the results. So how does ZiPS calculate the season? Stored within ZiPS are the first through 99th-percentile projections for each player. I start by making a generalized depth chart, using our Depth Charts as a jumping off point. Since these are my curated projections, I make changes based on my personal feelings about who will receive playing time as filtered through arbitrary whimsy my logic and reasoning. ZiPS then generates a million versions of each team in Monte Carlo fashion (the computational algorithms, that is — no one is dressing up in a tuxedo and playing baccarat like James Bond).

After that is done, ZiPS applies another set of algorithms with a generalized distribution of injury risk that changes the baseline PAs/IPs for each player. Of note is that higher-percentile projections already have more playing time than lower-percentile projections before this step. ZiPS then automatically (and proportionally) “fills in” playing time from the next players on the list to get to a full slate of plate appearances and innings. Read the rest of this entry »

1:00	Dan Szymborski: BASEBALL BASEBALL BASEBALL BASEBALL

1:00	Jay Jaffe: Hi everybody and a very pleasant good afternoon (or morning) to you wherever you may be. Happy 2023 baseball season and welcome to our Opening Day chat!

1:01	Jay Jaffe: Honestly, I don’t think it would take all that much — a couple of key rotation injuries to Houston and a few guys having bigger-than-expected seasons for Seattle while the Angels and Rangers don’t quite get there.

1:00	Dan Szymborski: The Mariners win a number of games in 2023 that is a larger number than the number of games that the Houston Astros and Los Angeles Angels win!

After an offseason marked by big free-agent contracts, big bases, and the introduction of the pitch clock, the 2023 season is almost upon us; we made it. And on this, the morning of Opening Day, we engage in our annual tradition of asking our staff to open themselves up to public ridicule and predict the year in baseball. Some of these predictions will prove to be prescient; others will make their forecaster feel a little silly. Last year’s Mariners? Our staff thought they’d finally bring an end to the franchise’s playoff drought, and wouldn’t you know it, they did just that. The division-winning Cleveland Guardians? We fared less well. Such is the prognostication business.

We asked the staff to predict the playoff field, pennant and World Series winners, and the individual award recipients. Folks from FanGraphs and RotoGraphs weighed in; here are the results. Read the rest of this entry »

Welcome back baseball! After an exciting and dramatic World Baseball Classic to whet our appetites, the main course is finally here. I introduced these power rankings a few years ago as a way to think about all 30 teams in baseball and stack them up against each other outside of the rigid structures of leagues or divisions. Nearly every major site has some form of power rankings, usually derived from whatever panel of experts each site employs. These rankings, though, are entirely data driven.

A reminder for how these rankings are calculated: first, we take the three most important components of a team — their offense (wRC+), their pitching (a 50/50 blend of FIP- and RA9-, weighted by starter and reliever IP share), and their defense (RAA) — and combine them to create an overall team quality metric. For these offseason power rankings, I’ve used each team’s projected stats based on their Depth Charts projections which are now powered by our blend of ZiPS and Steamer projections. I’ve also used the projected fielding component of WAR that appears on our Depth Charts projections as the defensive component for each team in lieu of RAA.

The Braves haven’t budged from the top of these rankings throughout this offseason. Sure, the Mets spent a ton of money this offseason, and the Phillies just went to the World Series, but Atlanta has owned this division for the last half decade. There are still some lingering questions, however. Orlando Arcia likely isn’t the long-term solution at shortstop, but both Vaughn Grissom and Braden Shewmake were optioned to Triple-A last week; the former has some defensive issues to work through, and the latter needs more exposure to high-level pitching before being handed a job in the big leagues. There are also some injury concerns in their pitching staff, with both Kyle Wright and Raisel Iglesias dealing with shoulder issues this spring and Michael Soroka not fully recovered from his many maladies. Still, this team is loaded with young talent and poised to win its sixth consecutive division title.

The big storyline for the Yankees this spring has been the competition for starting shortstop, with top prospect Anthony Volpe earning a spot on the Opening Day roster. That should provide youthful excitement to cover the very real concerns in the rotation and outfield. Harrison Bader likely won’t be out for long with his strained oblique, but his absence has revealed how shallow the position group is when Aaron Judge has to slide over to center field. And injuries of varying severity to Carlos Rodón, Luis Severino, and Frankie Montas aren’t exactly how you want to start off the season. Read the rest of this entry »

Sean Hjelle has been turning heads this preseason and seems to have pitched his way into a major league job. Then again, Hjelle turns heads everywhere; the former Kentucky Wildcat is the tallest player in baseball, at 6-foot-11, leaving him tied with Jon Rauch as the tallest player in MLB history. Anytime a pitcher above 6-foot-6 or so gets extended major league run, there’s an assumption that with a big body comes big velocity. That might be entirely Randy Johnson’s fault; Rauch sat in the low 90s, and until the end of last season, Hjelle didn’t throw much harder.

But as as he told Alex Pavlovic of NBCSN Bay Area early in spring training, Hjelle had been able to tickle 96 or 97 for one adrenaline-fueled inning in his last appearance of the 2022 season. This winter, his goal was to hold that velocity deeper into games. How? Well, to quote legendary Giants fan Huey Lewis, by working out most every day and watching what he eats. And after almost two months of training camp, Hjelle can look back and see the fruits of his labor. Read the rest of this entry »

Earlier today, we looked at the teams in the bottom half of the league’s rotations. Now to close out the positional power rankings, we look at the game’s best.

Welcome to the last installment of our positional power rankings (well, other than tomorrow’s summary post). We’ve saved the best for last, whether you’re looking for total projected WAR or stars named. The best pitchers in baseball are increasingly pitching together, leading to two- and even three-star team-ups that dot the top of our rankings. It’s still an overall squad ranking, though, which means the teams that emerge on top combine stars with depth that can chip in either to the back of the rotation or higher up if injuries demand it.

Oh, yeah: injuries play a big part in this year’s list. Whether it’s the Yankees and their strange mix of depth and uncertainty, the Rangers signing a trio of talented but oft-injured starters, or the Brewers hoping to get enough innings from the top end of their rotation to buy time to figure out the bottom, how the depth chart shakes out and how many innings the top starters pitch will determine who ends up getting the most out of their starters this year. It’s not even just injuries to stars; health matters for depth options too, as teams invariably find out when they’re calling James Shields in August to see if he’s available.

Yesterday, we ranked baseball’s bullpens. Today, we turn our attention to the starters, beginning with the rotations that project in the bottom half of the league.

The starting pitching pool is tightening once again. This year’s bottom half features four teams with a 40% or better chance at making the playoffs, including a pair of projected division winners. That isn’t because those teams are overrated and have bad staffs, either, but rather that there is a tight middle class of rotations in the league right now. The teams ranked ninth through 20th are separated by just 3 WAR, with the American League having eight of those clubs. The National League has an intriguing group of teams at 21st-24th that are all a breakout or two away from joining that middle class. Even the very bottom got a boost this year, as last year’s 30th-ranked club (Arizona) checked in with just 5.8 projected WAR while this year’s 30th-ranked Nationals are more than a win clear of that mark at 7.1 WAR. Both leagues have their bottom feeders, with the National League getting the 29th and 30th ranked squads and the American League checking in with the next four. Read the rest of this entry »

Earlier today, Kyle Kishimoto kicked off our reliever rankings. Now we’ll take a look at the bullpens projected to be baseball’s best.

There are some positions for which a cleaner, wider gap exists between the top teams and the bottom, where we can more definitively say that some teams are better than others. For instance, the combination of talent and depth that the Blue Jays have at the catching position separates them from the rest of baseball. Relief pitching is not one of these positions. Sure, we have the bullpens ranked, and you can see their statistical projections above and below, but be sure to notice how thin the margins tend to be here, and know that relief inning sample sizes are small enough that this is where WAR is the least good at properly calibrating impact and value. Things like managerial usage, depth, and roster flexibility tend to play a huge role in the way bullpens perform throughout a season, and those are factors we can’t totally control for here.

After wrapping up our position player rankings with the league’s designated hitters, we turn our attention to the pitchers, starting with the bullpens in the bottom half of the reliever rankings.

Relievers are really, really tough to project. From the tiny sample sizes of previous seasons’ work to uncertainty over a pitcher’s role and the wide variety of offseason mechanical and pitch mix adjustments they make in search of a big breakout, it’s uniquely difficult to accurately forecast the future effectiveness of individual relievers. Still, some relievers are clearly a cut above the rest, and a commonality among the teams in the bottom half of there rankings is that they don’t have many of them. Less than two wins separate teams no. 16 and 30, and in order to exceed their projections, they’ll be looking for their up/down or replacement-level arms to hit their high-percentile upside and factor as high-leverage options on their respective squads.

We conclude our rankings of the game’s position players with a deep dive on designated hitters.

Does anyone miss seeing pitchers hit? My guess is that the vast majority of you don’t, and for good reason. Pitchers have become increasingly dominant, which only increases the value of quality hitters, many of whom are utilized at the DH position. Some, like 42-year-old Nelson Cruz, fit the 1973 Orlando Cepeda mold, while others, like Shohei Ohtani… well, there are no others like Shohei Ohtani. If there has ever been a baseball unicorn, the Angels’ two-way superstar is just that.

Not all of players who see time at DH are defensive liabilities. Some clubs are blessed with positional depth and are looking for a way to fit a player into the lineup — Giancarlo Stanton and AJ Pollock are examples — while for others, it’s a matter of safeguarding health. Byron Buxton and Tyler Stephenson stand out in this regard. Read the rest of this entry »
