Looking Back at the 2022 ZiPS Projections

© Charles LeClaire-USA TODAY Sports

Before we get to the 2023 ZiPS projections, there’s still some unfinished work from 2022 to do. Looking at which projections went the most wayward is definitely an exercise that makes me soul cringe a bit, but in any model, being wrong is an important component of eventually being right. Calibration is a long-term project, and while chasing greater accuracy in mean projections isn’t likely to result in any huge bounty — there’s a reason projection systems are so tightly clustered — there’s still improvement to be had in things like calibrating uncertainty and long-term data.

Let’s start with how teams performed versus their projections:

2022 ZiPS Projected Wins vs. Actual Wins
Team ZiPS Real Difference
Baltimore Orioles 64 83 19
Los Angeles Dodgers 93 111 18
Houston Astros 90 106 16
Cleveland Guardians 78 92 14
New York Mets 88 101 13
New York Yankees 88 99 11
Atlanta Braves 90 101 11
Seattle Mariners 85 90 5
St. Louis Cardinals 88 93 5
Philadelphia Phillies 83 87 4
Toronto Blue Jays 88 92 4
Arizona Diamondbacks 71 74 3
San Diego Padres 89 89 0
Milwaukee Brewers 87 86 -1
Tampa Bay Rays 88 86 -2
Colorado Rockies 70 68 -2
Chicago Cubs 77 74 -3
San Francisco Giants 85 81 -4
Kansas City Royals 70 65 -5
Pittsburgh Pirates 68 62 -6
Chicago White Sox 88 81 -7
Detroit Tigers 73 66 -7
Minnesota Twins 86 78 -8
Los Angeles Angels 81 73 -8
Oakland Athletics 68 60 -8
Texas Rangers 77 68 -9
Boston Red Sox 88 78 -10
Cincinnati Reds 74 62 -12
Miami Marlins 82 69 -13
Washington Nationals 76 55 -21

Teams have gotten a bit more polarized in how they’re run in-season. Looking at the in-season ZiPS projections, roster strength has varied much more in recent years than when I started doing this. It wouldn’t be surprising to see the mean absolute error — for an exercise like this, I want to use the simplest tool that gets the point across — creep up over time. That is the case here, as the MAE of 8.3 wins is above the ZiPS historical average of 7.5 (not including 2020). ZiPS underperformed its usual matchup vs. Vegas, only going 17-13 in over/unders as of the date of release (April 6); historically, ZiPS has averaged 19-11. Read the rest of this entry »

40-Man Deadline Analysis: AL Central

© Mark J. Rebilas-USA TODAY Sports

Last Tuesday’s 40-man roster deadline led to the usual squall of transaction activity, with teams turning over portions of their rosters in an effort to make room for the incoming crop of young rookies. Often, teams with an overflow of viable big leaguers will try to get back what they can for some of those players via trade, but because we’re talking about guys straddling the line between major league viability and Triple-A, those trades tend not to be big enough to warrant an entire post. Over the next few days, we’ll endeavor to cover and analyze the moves made by each team, division by division. Readers can view this as the start of list season, as the players covered in this miniseries tend to be prospects who will get big league time in the next year. We’ll spend more time discussing players who we think need scouting updates or who we haven’t written about in the past. If you want additional detail on some of the more famous names you find below, pop over to The Board for a more thorough report.

The Future Value grades littered throughout these posts may be different than those on the 2022 in-season prospect lists on The Board to reflect our updated opinions, and may be subject to change during the offseason. New to our thinking on this subject and wondering what the FVs mean? Here’s a quick rundown. Note that because we’re talking about close-to-the-majors prospects across this entire exercise, the time and risk component is less present here and these FVs are what we think the players are right now.

The Big Questions About the 2023 BBWAA Hall of Fame Ballot

© Tim Heitman-USA TODAY Sports

If you were waiting for a time when the discussion around the BBWAA’s annual Hall of Fame voting didn’t center around Barry Bonds, Roger Clemens, and Curt Schilling, then I have good news: After 10 years of increasingly polarized debate, they all fell short of the 75% needed for election and have run out of eligibility on the ballot. They’re now candidates on the Contemporary Baseball Era Committee ballot — a problem for another day — but they’re not part of the 28-man slate unveiled by the Hall on Monday. That’s not to say that this ballot is devoid of controversial figures, or that debates about character are a thing of the past, but we can finally move beyond the cast that hit the 2013 ballot and spent 10 years monopolizing discussions and draining some of the fun out of the whole process.

The 2023 ballot doesn’t come without controversy, particularly in relation to the top newcomer, Carlos Beltrán. A nine-time All-Star and three-time Gold Glove winner who racked up 2,745 hits, 435 homers, and 312 steals, he’s got numbers to appease traditionalists, and likewise, he checks the advanced stat boxes by ranking eighth in WAR and ninth in JAWS among center fielders, thanks in no small part to the extra value he provided on the bases and in the field. For all of that, Beltrán is the player most closely identified with the Astros’ illegal sign stealing scandal, less because his own performance benefited (his 2017 season was below replacement level) than because The Athletic’s reporting and commissioner Rob Manfred’s subsequent report placed him at the center of the efforts to decode opposing catchers’ signs using the team’s video replay system.

Whether that is an offense grave enough to cost Beltrán a chance at Cooperstown is a matter for debate; his involvement in the matter already cost him his job as the Mets manager before he oversaw a single game. He returned to baseball this past year as a broadcaster for the YES Network, though no team has considered him for an in-uniform job since he left the Mets. Read the rest of this entry »

2023 Contemporary Baseball Era Committee Candidate: Dale Murphy

© Malcolm Emmons-USA TODAY Sports

The following article is part of my ongoing look at the candidates on the 2023 Contemporary Baseball Era Committee ballot. Originally written for the 2013 election at SI.com, it has been expanded and updated. For a detailed introduction to this year’s ballot, use the tool above. An introduction to JAWS can be found here.

It took four position changes — from catcher to first base, then left field, right field, and finally center field — and parts of five major league seasons for the Braves to figure out where the 6-foot-4 Dale Murphy fit. Once they did, they had themselves a franchise centerpiece, a wholesome, milk-drinking superstar whom Sports Illustrated profiled for its July 4, 1983 cover story by proclaiming, “Murphy’s Law is Nice Guys Finish First.”

The title was a reference to the slugger helping the Braves to an NL West title the previous year, their lone playoff appearance during the 1970-90 stretch. “Here’s a guy who doesn’t drink, smoke, chew or cuss,” wrote SI’s Steve Wulf. “Here’s a guy who has time for everyone, a guy who’s slow to anger and eager to please, a guy whose agent’s name is Church. His favorite movie is Frank Capra’s It’s a Wonderful Life. He’s a wonderful ballplayer.” Let the record show that Wulf did unearth some dirt on Murphy, noting that he once got a speeding ticket for doing 35 in a 25-mph zone… while running late to speak to a church group.

Murphy won the first of his back-to-back MVP awards in 1982 as well as the first of his five consecutive Gold Gloves, and made his second of seven All-Star teams. He would spend most of the 1980s as one of the game’s best players. Alas, knee problems turned him into a shadow of the player he once was while he was still in his early 30s, and he played his final game in the majors at age 37. Read the rest of this entry »


Meet the New Shortstop, Moderately Different From the Old Shortstop

© Brad Penner-USA TODAY Sports

While the top of the celebrated free agent shortstop market has yet to roll into motion, the end of last week saw a flurry of action a little lower on the positional power rankings. The Yankees agreed to a one-year, $6 million deal with Isiah Kiner-Falefa, locking up his final season of team control. And as Friday afternoon progressed, four other teams linked up for an exchange of shortstops. A shortswap, if you will.

Gio Urshela went from the Twins to the Angels for 19-year-old pitching prospect Alejandro Hidalgo, Kyle Farmer went from the Reds to the Twins for minor league pitcher Casey Legumina, and Kevin Newman went from the Pirates to the Reds for reliever Dauri Moreta.

A Chronicle of Indignity: Unjust Punchout Leaders

© Lindsey Wasson-USA TODAY Sports

Last week, I contemplated baseball as a carnival game. It gave me great joy because I think there should be more silly games in the world. It also gave me great joy because I got to spend hours watching beautifully located pitches, on a loop, for work. I wouldn’t necessarily recommend trying this yourself – bosses are wild these days – but trust me, it’s really fun.

Another thing I really enjoyed in writing that article was watching batters react to those perfectly placed pitches. One, in particular, stuck with me, so I snuck a piece of it into the piece. Here’s the full clip. In it, Vladimir Guerrero Jr. has either just realized he had a huge cryptocurrency position on FTX or been called out on strikes:

I love it. I love it so much. It makes me even happier that he wasn’t right. That was a strike! Everyone loves to think they’ve been wronged. Everyone has their own perspective. Vlad’s perception of the strike zone is surely that it smaller than the actual zone. In this case, the difference between perception and reality led to a delightful expression of disbelief.
