2025 ZiPS Projections: Arizona Diamondbacks

For the 21st consecutive season, the ZiPS projection system is unleashing a full set of prognostications. For more information on the ZiPS projections, please consult this year’s introduction and MLB’s glossary entry. The team order is selected by lot, and the first team up is the Arizona Diamondbacks.

Batters

Last year in this space, ZiPS was optimistic about the Diamondbacks bettering their 2023 win total. A big part of that was the computer predicting that the offense would be somewhere around average or (mostly) better everywhere except designated hitter. That’s generally what happened, and they even improved on that projection a bit, signing Joc Pederson at the end of January. The Snakes did, in fact, improve on their won total, going from 84 to 89 wins even though that wasn’t enough to squeeze into the postseason this go-around. Arizona actually led baseball in runs scored, edging out the Dodgers, and the team wasn’t even really aided by Chase Field, which is a much more neutral offensive environment than it used to be.

Tommy John spent 26 seasons pitching in the majors from 1963–74 and then 1976–89, more than any player besides Nolan Ryan, but his level of fame stems as much from the year that cleaves that span as it does from his work on the mound. As the recipient of the most famous sports medicine procedure of all time, the elbow ligament replacement surgery performed by Dr. Frank Jobe in late 1974 that now bears his name, John endured an arduous year-long rehab process before returning to pitch as well as ever, a recovery that gave hope to generations of injured pitchers whose careers might otherwise have ended. Tommy John surgery has somewhat obscured the pitcher’s on-field accomplishments, however.

A sinkerballer who relied upon his command and control to limit hard contact, John didn’t overpower hitters; after his surgery, when the usage of radar guns became more widespread, his sinker — which he threw 85-90% of the time — was generally clocked in the 85-87 mph range. He paired the sinker with a curveball, or rather several curves, as he could adjust the break based upon the speed at which he threw the pitch. He was the epitome of the “crafty lefty,” so good at his vocation that he arrived on the major league scene at age 20 and made his final appearance three days after his 46th birthday. He made four All-Star teams and was a key starter on five clubs that reached the postseason and three that won pennants, though he wound up on the losing end of the World Series each time.

Thomas Edward John Jr. was born on May 22, 1943 in Terre Haute, Indiana. He cut his teeth playing sandlot ball and more organized games at Spencer F. Ball Park, a three-block square with about 10 baseball diamonds used for everything from pickup games to those of two rival high schools, Garfield and Gerstmeyer, the latter of which he attended.

At Gerstmeyer, John excelled in basketball as well as baseball, so much so that the rangy, 6-foot-3 teenager was recruited by legendary Kentucky coach Adolph Rupp, and had over 50 basketball scholarship offers but just one for baseball (few colleges gave those out in those days). When Rupp paid a visit to their household, the senior John told the coach that his son was probably going to bypass college to pursue professional baseball. As the pitcher recalled in 2015:

Rupp said, “Well, we have a pretty good baseball team down in Kentucky, and your son might even be able to make our team.” My dad never liked Rupp, but that really made him mad. He told Coach Rupp, “Don’t let the door hit you in the ass on the way out.” Rupp was furious. His assistant came in and tried to smooth things over, but it didn’t matter.

On the mound, John lacked a top-notch fastball but had a major league-caliber curveball that he learned from former Phillies minor leaguer Arley Andrews, a friend of his father. He pitched to a 28-2 record in high school, and while the Cleveland Indians scout who signed him, John Schulte, expressed concern about his inability to overpower hitters, he signed him nonetheless two weeks after John graduated from Gerstmeyer in 1961 — four years before the introduction of the amateur draft.

Angels Sign Travis d’Arnaud to Bolster Depth

Charles LeClaire-USA TODAY Sports

Most of the time, you can count on early November to take a break from following baseball news. The World Series has just ended, but free agency hasn’t started in earnest. International free agents generally get posted closer to the mid-December deadline. Big trades are more of a December/January thing. But the Angels don’t operate that way. First they traded for Jorge Soler. Then they signed Kyle Hendricks. Now they’ve signed the first multi-year free agency deal of the offseason, linking up with Travis d’Arnaud on a two-year, $12 million contract.

At first blush, this feels like so much shuffling of deck chairs. The Angels have a lot of needs, to put it bluntly. Catcher was one of their best positions last year. They need more starters, more relievers, more outfield depth, more infield depth, and more top-of-the-order bats. Incumbent Logan O’Hoppe was one of only three hitters on the team to eclipse the 2-WAR mark. Why not sign a second baseman, or another starting pitcher, or pretty much anyone else?

I think there’s more here than meets the eye, though. We’re not talking about a blockbuster signing, and quite frankly, we’re not talking about a playoff team. A good season for the Angels in 2025 would mean flirting with .500 and developing a few new everyday players. Maybe Jo Adell will take a step forward and Mike Trout will play a full season at his normal standard of excellence. Maybe Zach Neto will continue on his current trajectory towards borderline All-Star production (once he’s back from shoulder surgery, of course) and Reid Detmers will rediscover his wipeout slider.

Did WAR Ruin the MVP Conversation?

Brad Penner-USA TODAY Sports

On Wednesday, I wrote about one of my favorite topics: The impact of sabermetrics on the practice and analysis of baseball. Specifically, in this case: How MVP voters behave in the post-Fire Joe Morgan era. And for those of you who got to the end of that 2,000-word post and did not feel sated, there’s good news! This was not the question I actually set out to answer when I started kicking the topic around.

Welcome to Part 2.

The very name of the MVP award invites voters to consider the value of a certain player’s contributions. For nearly 100 years, that was a tricky proposition. How do you weigh differences in position, in playing style, park factors, hitting versus pitching versus fielding versus baserunning? It’s enough to boggle the mind. Read the rest of this entry »


FanGraphs Power Rankings: Offseason 2025

The hot stove is currently set to simmer, as teams have completed their annual roster housekeeping, but any big moves are still on the horizon. That means it’s the perfect time to see how all 30 teams stack up. The rankings below present each team as they are currently constructed, based on our playing time estimates. This should give us a pretty good idea of which teams would be ready to compete if the season started today, and which ones still have work to do to get their 2025 roster in order.

This year, we revamped our power rankings using a modified Elo rating system. If you’re familiar with chess rankings or FiveThirtyEight’s defunct sports section, you’ll know that Elo is an elegant solution that measures teams’ relative strength and is very reactive to recent performance. For these offseason rankings, I’ve pulled the Depth Charts projections and calculated an implied Elo ranking for each team. Our projections are entirely powered by the 2025 Steamer projections right now; the 2025 ZiPS projections will be added later on in the offseason. The delta column in the full rankings below shows the change in ranking from the final regular season run of the power rankings. Read the rest of this entry »


Mark Loretta Talks Hitting

Byron Hetzler-USA TODAY Sports Copyright (c) 2007 Byron Hetzler

Mark Loretta was a solid hitter over 15 big league seasons, and he was especially good in 2003 and 2004. Over that two-year span, the right-handed-hitting second baseman slashed .325/.382/.469 with 75 doubles, 29 home runs, and a 129 wRC+ with the San Diego Padres. Contact was one of his strong suits. The Northwestern University product had a 7.9% strikeout rate to go with an 8.2% walk rate in 2003-04, numbers largely in line with his 9.2% and 8.5% career marks.

His overall production was comparably modest. Loretta consistently put up high batting averages – they ranged between .280 and .335 during his 11 full seasons — but he went deep just 76 times and finished with a 100 wRC+. Those numbers came over seven-plus seasons with the Milwaukee Brewers, three with the Padres, two-plus with the Houston Astros, and one each with the Boston Red Sox and Los Angeles Dodgers. Your prototypical “professional hitter,” Loretta debuted in 1995 and played his last game in 2009.

Now a special assistant with San Diego, Loretta sat down to talk hitting when the Padres played at Fenway Park in late June.

———

David Laurila: Looking back, what style of hitter were you, and did that change over the course of your career?

Mark Loretta: “That’s a good question. I would say that I was developed and came up as [someone who hit] inside the ball, hit the ball up the middle, hit it the other way, hit it where it’s pitched. I was very contact-oriented. I didn’t really sit on pitches or sell out for fastballs, I mainly liked to see the ball get deep.

“About halfway through my career I made a concerted effort to learn to pull the ball better, and more often. I think that’s when my career sort of took off. I was able to get to keep that contact-hitter, hit-it-where-it’s-pitched approach, but also handle the ball inside much better.

“My power — more doubles, more home runs — came when I pulled the ball. For a lot of my career, pitchers would pound me in, pound me in, because I hit the ball well the other way. I made a couple of adjustments with my swing and started looking a little bit more in when I was in hitter’s counts. I would lay off the ball middle-away when it was 2-0 or 3-1.”

Did Sabermetrics Ruin the MVP Conversation?

Kirby Lee-Imagn Images

Next Thursday night, we’re going to find out who won the biggest individual honors in baseball: the Most Valuable Player awards for both the American and National Leagues, as determined by the august and esteemed voters of the Baseball Writers’ Association of America. (Cue trumpet fanfare.)

MVP awards memorialize great individual performances and bestow immense historical significance upon the players who earn them. This is the kind of thing Hall of Fame cases are built on. So you’d think the entire baseball-watching public would be glued to MLB Network or refreshing the BBWAA website on Thursday evening. But… maybe not. Aaron Judge and Shohei Ohtani are almost certain to win, and I guess it’s worth checking social media after dinner just to make sure.

There’s surprisingly little drama over awards these days; postseason betting odds on the MVP races were a little hard to come by, as most bookies have taken the issue off the board. But consider this as a measure of public sentiment: In early October, BetMGM had Judge as a 1-to-50 favorite in the AL, and Ohtani as a 1-to-100 favorite in the NL. Despite a spirited contrarian push by the pro-Fancisco Lindor camp late in the season, it’s all over but the shouting. Read the rest of this entry »

Juan Soto’s Patience Is a Virtue

Brad Penner-Imagn Images

Juan Soto hates swinging.” That’s a takeaway you’re sure to hear if you follow baseball this winter. His free agency is the biggest story of the next few months, and his offensive approach drives fans to distraction. Walks aren’t all that fun, and Soto feasts on them. How could you not bring it up when your team is pursuing him for a record-breaking deal?

From a certain standpoint, it’s true that Soto hates swinging. Of the 101 batters who saw at least 1,500 pitches with zero or one strikes this past season, Soto ranked 99th in swing rate on those pitches. When he isn’t defending the plate with two strikes, he spends a ton of time with the bat on his shoulder.

That’s not a specific enough way of looking at it, though. For an example, let’s chop the strike zone up into pieces. Soto saw 675 pitches that weren’t in the strike zone or even near it – what Baseball Savant defines as the chase and waste zones. He swung at 6.5% of those, 42nd out of the 44 batters who saw 500 or more such pitches. He was almost never fooled into swinging at awful pitches, in other words.

Next consider the edges of the zone – pitches that are either barely strikes or barely balls. There aren’t a lot of good options on these pitches. Hitters don’t generally crush the ball when it’s located on the corners, unless they’re sitting on either a pitch or a location. Sure, if you’re looking high and away, you might tag it, but more likely you’ll swing and miss or make weak contact. Soto swung at 31.3% of these pitches, the second-lowest rate in baseball.

Those pitches in the chase and waste zones? You shouldn’t swing at them. There, Soto’s patience is an obvious asset. The ones on the borderline? It’s less obvious. There are great hitters who take an expansive approach to borderline pitches, like Bobby Witt Jr. and Yordan Alvarez. There are awful hitters who do it too, as you’d expect. Swinging too much at offerings we call “pitcher’s pitches” is pretty clearly not going to pan out every time.

Likewise, discretion is no guarantee of valor. There are great hitters who, like Soto, mostly let these pitches go. Aaron Judge and Kyle Schwarber fit the bill. It’s not just high-walk-rate sluggers, either; Matt Chapman, Adley Rutschman, Nolan Arenado, and even Randy Arozarena behave this way. On the other hand, plenty of bad hitters take borderline pitches and are still bad.
