Back in April, 23 of our writers and contributors made predictions about the 2022 season. When guessing who would be the AL Rookie of the Year, nine different players were named, with Bobby Witt Jr. and Julio Rodríguez leading the pack. Not found among those nine names was the starting shortstop for the Astros, a rookie faced with the difficult task of replacing incumbent Carlos Correa, who had gone to the Twins. Jeremy Peña wasn’t pegged as a ROY frontrunner, but for much of the early season, he looked like a sudden superstar. However, he’s struggled offensively in recent months, raising some questions about whether the real Peña is the player with the .878 OPS through mid-May, the one with a .586 OPS since the All-Star Game, or somewhere in the middle.

Back in May, Witt, the preseason favorite, wasn’t even in the top 15; Rodríguez only put up a .544 OPS over April; and Adley Rutschman was days away from even debuting in the majors. While Peña wasn’t making Astros fans actually forget about Correa, he certainly did his best to alleviate any lingering worries about their former franchise building block heading to the AL Central. But since May 17, he has seen his control over the AL leaderboard disappear:

That’s not to say that Peña hasn’t continued to be a solid overall player, but his largest contributions in recent months have been with leather rather than wood. With his range measured at five runs above average at shortstop by Statcast’s RAA and a total of nine runs over all facets of defense by our estimate, he hasn’t disappointed defensively, which has enabled him to remain a legitimate starter even with his offense dropping to disappointing levels. But he’s a far more exciting player with his spring offense, so what went wrong there? Read the rest of this entry »

There are not many subjects that baseball teams agree on, outside of not paying minor leaguers much money. One thing that 29 teams do share is an enormous amount of regret that they didn’t convince Shohei Ohtani to come join their franchise after the end of the 2017 season. (OK, 28 teams since the Orioles bizarrely refused to make a presentation on philosophical grounds, but I’d wager that the current front office would not have operated the same way!) In any case, major league teams and fans who pay attention regularly covet the biggest stars in NPB (Nippon Professional Baseball), and a small but steady flow of talent comes to the United States and Canada from overseas. So I wanted to take a look at two Japanese players who, while they may not be the next NPB stars to come to MLB due to the vagaries of the posting system, are the most exciting young players in the league right now: Tokyo Yakult Swallows third baseman Munetaka Murakami, and Chiba Lotte Marines righty Roki Sasaki.

It would be difficult to overstate how dominating Murakami has been at age 22, but I’m going to try my best to do so. Called up for a cup of coffee at 18 years old in 2018, he quickly became one of Japan’s best hitters, slugging 36 round-trippers at age 19 and putting up OPS figures of 1.012 and .974 in the two years since. Like MLB, NPB is at a fairly low offensive environment these days, though it’s unlikely the underlying causes are similar. The Central League — pretty much the last bastion if you like seeing pitchers hit — is only scoring 3.64 runs per game, its fewest since 2015. That hasn’t kept Murakami from not just finding another gear in 2022, but enough extra gears that it looks like he emptied out a bicycle shop.

At 52 homers, Murakami is not merely at the top of the standings; he is the standings. Only a single player in Japan, Hotaka Yamakawa, has even half the home run total (38). There are only two players within 300 points of his 1.229 OPS: Yamakawa (.988) and Masataka Yoshida (.952), and that’s while using a fairly generous plate appearance requirement (250 PA). In recent weeks, Murakami also set an NPB record by hitting home runs in five consecutive plate appearances.

This type of home run dominance is rare, and Aaron Judge may be the first hitter in nearly a century to beat the runner-up by as large a margin as Murakami’s current one. OPS dominance to this degree is just as rare, even using the same liberal 250 plate appearance threshold rather than the official 3.1 plate appearances per team game, with only Babe Ruth and Barry Bonds matching Murakami’s current edge.

The Arizona Diamondbacks don’t generate a lot of national headlines these days, but the team’s ace, Zac Gallen, is trying his best to change that. Since a Luke Maile double knocked him out of a game against the Guardians on August 2, Gallen has racked up six consecutive scoreless games, covering 41 1/3 innings. Gallen’s run has gone on long enough to have historical significance: He currently ranks 17th in baseball history, at least the history during which usable game logs exist (since around the start of the 20th century). He’s two outs from catching Brandon Webb’s 2007 streak to set a new Diamondbacks franchise record, and another 3 2/3 innings will slot him into the top 10, tying his with the streaks of Cy Young, Sal Maglie, and Doc White.

Naturally, most streaks of this nature involve a player playing well above their established level of ability, and Gallen is no exception. But every pitcher with a scoreless innings streak this long was at least solid, with nary an incompetent journeyman in sight. Gallen is again no exception and was having a solid season even before the streak started. Entering play on August 2, he had an ERA of 3.24 and a FIP of 3.69 in 19 starts, above-average numbers, though not good enough to force his way into the Cy Young conversation. (Earlier today, Baseball Prospectus‘ Michael Ajeto published a deeper examination of some of the changes Gallen has made during the scoreless streak that is worth a read.)

The Orioles showed mercy to minor league pitchers this week, officially calling up infielder Gunnar Henderson, relieving those hurlers of the terrible burden of having to pitch to him. The team’s top prospect wasted little time making his impact felt, hitting his first major league home run in his second time up at the plate, a long drive off Cleveland starter Triston McKenzie. And if the ZiPS projections are to be believed, adding Henderson down the stretch is about as valuable an offensive boost as anyone made this summer, with the obvious exception of a certain southern California team sporting mustard-and-brown colors.

So just how good is Henderson? That’s a question that has shifted notably over the course of the minor league season. If you go back to the winter, he was considered an excellent prospect, ranking 66th in the FanGraphs Top 100 list and 53rd in the ZiPS Top 100. We weren’t outliers, either; among others, Keith Law at The Athletic and Baseball Prospectus also put him in their top 100s.

Henderson’s stock wasn’t poorly valued, but it shot up so quickly this year that you might think that it was a Reddit meme stonk like GameStop and AMC. Minor league translation printer goes brrr! Before the season, ZiPS only projected Henderson to amass 1.5 WAR in 2023 with a wRC+ of 87. We’ll get to that updated 2023 projection in a minute; let’s just say for now that it’s better.

The improvements made by Henderson in the minors this year were across the board, from power to plate discipline to defense. Combining his performances for Double-A Bowie and Triple-A Norfolk, you get an overall line of .297/.416/.531 with 19 homers and 22 stolen bases in 112 games. That would be enough to make him the best first base prospect in baseball, considering he didn’t turn 21 until late June, but as a player who can legitimately play shortstop, that’s the kind of performance that puts you in the ultra-elite category.

Since I’m an obnoxiously determined Devil’s advocate, one of my favorite uses of data is tackling conventional wisdom. For example, one such bit of wisdom that always bugs me is when pundits insist that the best teams are the ones that win close games. In fact, the opposite is true. The most predictive run differential comes in blowouts — the good teams are the ones that are more likely to humiliate their opponents, not squeeze out a close one. This time of year, you start to see a lot of analysis asserting that X team is definitely blessed or doomed come playoff time because of some randomly chosen factor Y. We could do a column a day on these and still have dozens of unwritten pieces by the time the actual playoffs roll around, but let’s focus on a few specific ones, concentrating on who good teams beat rather than how many games they win.

First off, do regular season head-to-head records matter in the playoffs? Since the start of divisional play in 1969, teams that face each other in the playoffs have frequently met in the regular season. Interleague play added eventual World Series matchups to the regular season, and starting in 2023, every playoff matchup will have already occurred during the regular season. Given the sample size of playoff series, if we construct a simple model of series winning percentage that only consists of a team’s regular season winning percentage and its winning percentage in head-to-head matchups, the model horribly inaccurate, with an r-squared of 0.0886 and a mean absolute error of 275 points of winning percentage.

But including head-to-head winning percentage doesn’t really even have a marginal influence on the coin flip; without the head-to-head matchups, the model’s MAE increases to 276 points of winning percentage. Now, a head-to-head record may imply something about a team’s overall strength that isn’t captured in its overall record, but rather than pick up a small sample implication, we can use strength of schedule directly, which does help the model a tiny bit (playoff series are always going to be very uncertain unless we move to best-of-75 series or something wacky).

It’ll still be a few months before we see whether Julio Rodríguez wins the American League Rookie of the Year award, but today we got a glimpse of baseball 15 years into the future. As reported by MLB.com’s Jesse Sanchez and ESPN’s Jeff Passan, the Seattle Mariners and Rodríguez have come to terms on a huge long-term contract extension, one that would run to the late 2030s.

Passan ran down the details of the deal, and it’s a complicated one.

THREAD: There’s a lot to digest on Julio Rodríguez’s extension with Seattle, per ESPN sources. The deal could be for 8, 13, 16 or 18 years. It guarantees Rodriguez $210 million. If it maxes out, it will be the largest ever: $470 million. The details are important. Here they are.

On Thursday, MLB announced the 2023 schedule, implementing the alterations originally announced when the current collective bargaining agreement was signed back in March. The existing format, under which the 2022 season is being played, has been largely stable since 2013, the season the Houston Astros moved to the American League. That change evened out all six divisions to five teams each, making for a tidy format in which every team played their divisional opponents 19 times and the rest of the teams in their league six or seven times, with 20 interleague games against a rotating division and officially designated MLB rivals.

Before 2001, MLB’s schedule tended to be a good deal more balanced. During the divisional era before interleague play, six-team divisions typically played 18 games against their divisional opponents and 12 against non-divisional opponents; seven-team divisions had a nearly even 13/12 split (the American League did 15 vs. 10 or 11 for a couple years after the 1977 expansion). In 2001, MLB went all-in on an unbalanced schedule, with the idea being that by having teams play their divisional rivals more often, you’d create greater tension in the divisional races and more intense regional rivalries. Whether this approach actually accomplished its goals is difficult to tell. I can’t think of any new rivalries that were created simply by playing more games and tend to believe that rivalries are born from teams playing more meaningful games against each other, not simply from seeing each other more often. Red Sox and Yankees fans don’t appear to have hated each other any more in 2010 than they did in 2000, and the endless Orioles-Rays series in the days before Tampa Bay was competitive made this O’s fan click over to other games, not foster a hatred for the Rays.

Be that as it may, from a philosophical standpoint, heavily unbalanced schedules make the most sense when winning divisional races is the sole or at least primary way of making the playoffs and much less so when more Wild Card spots exist. When you have a lot of Wild Card spots, you create a fundamental bit of unfairness when the divisions are of meaningfully differing strengths; teams in weak divisions are competing directly against teams in stronger divisions for those Wild Card spots, with the former generally having easier schedules.

After having arguably the best season of his professional career in 2021, Carlos Rodón signed a rather modest two-year, $44 million contract with the San Francisco Giants. For a large part of the 2021 season, it looked like he was headed toward a much more headline-grabbing dollar amount. After years of missed time, first due to shoulder problems and then a Tommy John surgery, Rodón shocked the baseball world by returning with a much hotter fastball than he’d previously ever had. Never reaching the heights the White Sox expected when they took him with the third overall pick of the 2014 draft, he was bordering on bust status before suddenly re-emerging as an All-Star. Literally — he made his first All-Star team in 2021.

But a few nasty surprises kept Rodón from getting the payday aces typically get. Given his injury record — he’d only been healthy enough to qualify for an ERA title once — there were inevitable concerns about his durability, an important consideration when you’re doling out nine-figure contracts. Those fears were realized in the second half of the season, as Rodón missed time due to shoulder fatigue and soreness. It wasn’t that he struggled; most teams would have been overjoyed with his 3.26 second-half FIP. What was highly concerning was the dramatic velocity loss he experienced, an extremely inauspicious sign for a pitcher: Read the rest of this entry »

Three years ago, everything was coming up Cody Bellinger’s way. The NL Rookie of the Year in 2017, he broke out in a big way in ’19, smashing 47 home runs with an OPS over 1.000 and edging out Christian Yelich for his first (and only) MVP hardware. Bellinger had even taken to playing excellent defense in center field, not something typically on the curriculum vitae for a young first baseman. Entering his age-24 season, everyone expected that he’d be a star for the next decade or so and a building block for the Dodgers as players like Corey Seager were approaching free agency.

The ZiPS projection system, known for being the grumpy devil’s advocate as most such systems are, didn’t see any particular reason for concern, either. If you wanted Los Angeles to sign Bellinger to a lucrative contract extension, guaranteeing he wore Dodger blue for a long time, you had a loyal friend in ZiPS:

In rest-of-career WAR, Bellinger ranked third among position players, behind just Juan Soto and Ronald Acuña Jr.

Now, if this were a comedy movie, this is the point in the trailer at which you hear the record scratch, the narrator describes the humorous change of fortune, and then the music changes to an upbeat pop hit song with clips of how Bellinger gets back everything he lost and learns about the incredible power of friendship. But it’s not. Since that NL MVP season, he has hit .200/.271/.380 in over 1,000 plate appearances, only finishing above replacement level by virtue of the fact that he at least still remembers how to play defense. This is less Pixar and more Darren Aronofsky. Read the rest of this entry »
