Let me get this out of the way: Nick Madrigal is really good at baseball. Or at least, he’s really good at one aspect of it, and that aspect is one of the most important ones. Madrigal’s bat control is borderline otherworldly. Per FanGraphs’ measurements, Madrigal entered Sunday’s contest with a 100% in-zone contact rate. 100%! That’s zero swings and misses in the zone. Nearly 20 games into the season, that’s a remarkable achievement. Arguably more impressive is his 90.2% contact rate out of the zone. When he chases, he still hits the ball. Currently, only 31 qualified hitters have a higher in-zone contact rate than Madrigal has when leaving it. In terms of putting the bat on the baseball, Madrigal is a pure 80. It’s an amazing ability, and it’s one reason that, barring injury, it’s easy to see him hitting .300 or better for the next decade or more.

The question is how valuable can Madrigal be beyond his remarkable ability to make contact. He’s the ultimate “empty average” guy due to an aggressive approach and a complete lack of power. Entering Sunday’s game, Madrigal is a .327 hitter in his young, 47-game career. He has a .757 OPS to go along with that. Again good, but not as good as you’d expect from someone challenging for a batting title. ZIPS sees the weird combination of plusses and minuses and has Madrigal peaking at 2.3 WAR with a 101 OPS+. In order to go from good to really good, Madrigal is going to have to either walk more or hit balls harder, and he has a harder path than most in terms of making either happen.

Scouts call players like Madrigal “early action” players. Swing at a lot of pitches, make a ton of contact. That’s Madrigal in a nutshell. He’s not going to walk, and he’s not going to strike out. In fact, he’s going to do those two things less often than anyone in the game. We’re all familiar with walk and strikeout percentages, but what happens when we combine them? Let’s call it Early Action Percentage:

Which players are most essential to their team’s postseason odds? While that list contains many of the best players in baseball, it’s not a strict ranking of the sport’s brightest stars. When looking at who is the most irreplaceable in the short-term, there are questions beyond just how good the player in question is. It becomes a matter of marginal utility. To a team already saddled with a doomed 2021 outlook, losing a star is unfortunate — obviously very much so for the player in question — but won’t really affect their chances of making the playoffs. The Colorado Rockies could build a time machine, kidnap Ted Williams, and stick a very confused Splendid Splinter in their lineup and it still wouldn’t change their near-term fate. And the same goes for teams at the opposite end of the spectrum — you can’t tip over your house with a leaf blower.

Of course, some teams are simply better equipped to deal with these kinds of nasty surprises than others, able to rely on enviable depth to weather absences. Two such nasty surprises have happened recently and illustrate the point well, albeit in opposite directions. Stephen Strasburg of the Washington Nationals was placed on the Injured List with shoulder inflammation after a mess of a start that saw him caught rubbing his shoulder on camera. (For more on the Strasburg injury, check out my colleague Jay Jaffe’s piece discussing what it means to Washington.) Another scare involved Mookie Betts, who took a hard, high-and-in offering from Rafael Montero directly on his forearm.

Luckily, Betts’ injury seems unlikely to sideline his for long — Dave Roberts says he expects him back later this week — but even if it had meant a longer absence, the Dodgers would have had little need to panic. Even in the worst-case scenario, where the team loses him for the rest of the season, it’s hard to derail this playoff train; the ZiPS projections have their playoff probability collapsing from 99.6% to…97.5%. A drop-off of two percentage points is a relatively minor one, smaller than the projection change if the White Sox lost Adam Eaton or the Astros had to suddenly replace Yuli Gurriel. Presumably, we have unanimous agreement that Betts is easily the most valuable player listed here.

The Nationals, on the other hand, are very reliant on their stars. Should they lose any of their key players — mainly Strasburg, Juan Soto, Trea Turner, Max Scherzer — it would nearly doom their October hopes. Soto joined Strasberg on the IL yesterday after suffering a strained left shoulder. Losing him for the duration would cause the club to miss the playoffs in 81% of the simulations in which the Nats would otherwise make it.

As steep as that sounds, from a quantitative standpoint, losing Soto isn’t the biggest possible loss in baseball in terms of playoff probability; ZiPS already sees the Nats having an uphill climb at 12.2%. The teams that have the most to lose are those with two key elements: a playoff fate that is very much undecided and and a lack of ready replacements elsewhere in the organization. So, as of Tuesday morning, here are baseball’s most irreplaceable players. The below changes in playoff odds assume a season-ending injury and the use of an in-house replacement. Just to illustrate how changeable this list is, only two of the top 10 are repeats from 2020.

Mike Trout, Los Angeles Angels (-35.5%)

As the best player of his generation, Trout has a way of finishing at the top of lists, but his placement here is actually fairly unusual. He has sometimes missed this ranking completely, as the Angels have an impeccable record of building inadequate teams around their franchise player. But the AL West is open enough, and the Angels are good enough, that this is the year they really can’t afford to lose him. Trout going down would already be a huge loss even if the Angels had an extra league-average outfielder hanging around the roster. But with the likely in-house solution being to shuffle around the outfield, resulting in more playing for Juan Lagares and some combination of Scott Schebler and eventually Taylor Ward, that’s not the team’s situation.

Gerrit Cole, New York Yankees (-29.5%)

That Cole ranks so highly is not a slight on the quality of the Yankees’ starting pitching. They’re actually quite deep with interesting, talented arms who could step in if the worst should happen and they lose their ace. What is a problem is that after Cole, the Yankees have a lot of pitchers with spotty injury records. ZiPS already assumes that the team will have to turn to that depth multiple times before 2021’s final pitch is thrown. To lose the guy they want to set-and-forget at 200 innings would be a big blow. Complicating the picture is that while the Yankees are still the favorite, their slow start does matter and means that they’ve already lost a good chunk of their margin for error over the Rays, Blue Jays, and Red Sox in the division.

Ronald Acuña Jr., Atlanta Braves (-28.3%)

Acuña wasn’t the National League MVP in 2020, but he’s certainly the player I’d least like to lose if I owned the Atlanta Braves. All the projection systems love him for obvious reasons, but none more than ZiPS, which sees him as the only player in baseball to have non-laughable odds of becoming baseball’s first 50/50 club member. Drew Waters, Ender Inciarte, and Guillermo Heredia could replace the at-bats, but none of them have the recipe to replace the awesomesauce Acuña uses to feast on opposing pitchers.

Alex Bregman, Houston Astros (-28.1%)

Houston’s rotation depth over the last four years has descended from utopia to yikes and now the team’s offense is absolutely crucial to the Astros playing October baseball. The franchise’s offensive core may have originally been led by Jose Altuve and then Carlos Correa and George Springer, but Alex Bregman is now The Man, the hitter they can least afford to have missing from the lineup. ZiPS sees Aledmys Díaz and Abraham Toro as better-than-replacement talent, but Houston’s unlikely to run away with the division the way it has in some recent seasons, making every win crucial.

Jacob deGrom, New York Mets (-25.0%)

deGrom drops from first to fourth on the list, but that’s not due to any decline in his performance. Rather, with the Mets under new ownership, the team didn’t go into the season with five starting pitchers who looked good on paper and a roster that couldn’t withstand injuries to the rotation. This time around, the Mets actually have options. None of them could fully replace deGrom, mind you, but plenty could at least be respectable fifth starters on a good team.

Carlos Correa, Houston Astros (-24.1%)

Given Correa’s injury history, the fact that he ranks highly on a list like this should greatly concern the Astros. ZiPS sees Bregman as the clearly superior player but also sees the options after Correa as less enticing. Díaz isn’t a particularly good defensive shortstop, and Toro wouldn’t be an option at the position. Alex De Goti has interesting power but is a massive downgrade from Correa. Houston would likely have to explore a trade if misfortune befell Correa, but the team may have other needs, so that’s not a great scenario either.

Luis Robert, Chicago White Sox (-23.2%)

From a straight-up projection standpoint, Robert falls short of most of the names on this list. Just on the Sox, ZiPS thinks Lucas Giolito is a significantly more valuable player overall, at least when he’s not pitching in the morning. But if something should happen to Giolito, Chicago has spare arms to patch up the hole. If the team loses Robert, let’s just say ZiPS does not have a case of Leurymania or Engelalia. The race with the Twins is likely going to be a tight one and the Royals have shown surprising spunk. The White Sox could ill afford an injury to their center fielder.

Byron Buxton, Minnesota Twins (-22.7%)

Is this the year that Byron Buxton finally stays healthy and is awesome? In just nine games, he’s already collected an impressive 1.5 WAR! Buxton will fall off from his 15-WAR pace, of course, but a lot of the scenarios in which ZiPS sees Minnesota taking down Chicago involve a solid season from Buxton. Even if his offense regressed hard toward his career 93 wRC+, the team would struggle to replace his glove, which has remained a major plus even through his various injuries.

Anthony Rendon, Los Angeles Angels (-21.8%)

To nobody’s surprise, Rendon isn’t quite the player that Mike Trout is. But the Angels have real playoff hopes, and even with the team having better replacements for injured infielders than outfielders, it would struggle to replace Rendon. Franklin Barreto’s elbow is enough to just squeeze Rendon onto this list, where he’d otherwise finish 12th, with Gleyber Torres taking the 10-spot.

Freddie Freeman, Atlanta Braves (-21.7%)

I love Pablo Sandoval, but not as my starting first baseman. Nor would Austin Riley playing first (with Johan Camargo, Orlando Arcia, and Ehire Adrianza pitching in at third) remedy the situation. Freeman’s the best first baseman in baseball, and even if the position isn’t as important as it was 40 years ago, he’s a crucial part of the lineup.

When Carlos Rodón hit Roberto Pérez in the left foot with one out in the ninth inning of Wednesday night’s game, just about everybody watching who wasn’t pulling for Cleveland let out a collective groan. With one errant pitch, the 28-year-old lefty had lost his shot at completing just the 24th perfect game in major league history, and the first since the Mariners’ Felix Hernandez in 2012. He recovered in time to get the final two outs to complete a no-hitter, the second of the young season — not only a pretty cool accomplishment unto itself but an especially impressive one given the injuries and other ups and downs the former number three draft pick has endured in recent years.

Before Rodón even hit Pérez, he’d already done something cool, though, thanks to the tremendous lunge made by José Abreu to tag first base before Josh Naylor reached safely to start the ninth inning.

That out was the 27th in a row collected by Rodón, giving him a “hidden perfect game” across multiple appearances dating back to his April 5 start against the Mariners. In the fifth inning of that game, he bounced back from hitting Ty France on the right foot with a pitch to retire Kyle Seager and Evan White on balls hit to left field, completing five scoreless frames and starting his streak.

On his 110th pitch of the night, Carlos Rodón hit 99 mph on the radar gun. It was a wasted pitch, a ball that evened the count to Jordan Luplow at 2-2. Four pitches later, Rodón slowed it down, dropping in a changeup that Luplow rolled harmlessly to third base. Yoán Moncada fielded it cleanly and fired to first for the last out of the game. Rodón had thrown a no-hitter, the first of his career.

Don’t worry, we’ll get to that momentous event. I want to talk about that fastball first, though, because it’s also remarkable. That pitch was the fastest pitch a White Sox starter has thrown this year — tied, actually, with a Dylan Cease offering. Cease is a flame-throwing 25-year-old with a 70 fastball grade — a plus-plus pitch that anchors his entire game. Rodón hadn’t crested 93 mph in average fastball velocity since 2017. He pitched only 7.2 innings last year, and hasn’t topped 150 since 2016. In an increasingly young man’s game, Rodón seemed somehow past his prime at only 28.

In last year’s playoffs, he made the roster as an afterthought. He faced three batters, as a last resort in the team’s disastrous playoff exit — all three reached, the third on an intentional pass that fulfilled the three-batter minimum, and it would hardly have been a surprise if that was his last pitch in black and white. In a money-saving move, the Sox didn’t tender him a contract after the season.

He signed a one-year deal in February to return to the team, but his rotation spot was anything but guaranteed; the team held a more-or-less open competition for its fourth and fifth starter spots this spring. An offseason workout regimen and some rare but welcome good health helped him secure a spot, and a successful first start against the Mariners — 95 pitches and nine strikeouts in five scoreless innings — cemented it.

That brings us back to Wednesday night. After an uneventful top of the first, the White Sox offense did their best to remove all drama from the game. They pounced on an ineffective Zach Plesac, chasing him from the game after seven hits and six runs. Rodón, whose first fastball of the night left his hand at 91.1 mph, sat in the dugout and watched.

We’re now about 10 days into the season, which means it’s time for a round of “Who’s looking good out of the gate?” Today, I want to focus on three post-hype starters who piqued my interest in the last week: Carlos Rodón, Jeff Hoffman, and Justin Dunn. Obviously, these three have teased before, and given their track records, there’s good reason to be skeptical of them going forward. All three have good arms though, and I’m a sucker for a spring breakout. With that in mind, I’ve donned my yellow zigzagged shirt, taken a running start, and am ready to blast this metaphorical football.

I trust that a small sample warning isn’t really necessary here. We all know that we’re working with extremely limited data at this point in the year, and that the following content comes with an extra-large SSS warning label. I trust you to recognize the intent of this article, which is simply to highlight interesting starts from a few talented but oft-frustrating arms. I’m not declaring that they’re suddenly budding All-Stars; I’m not even arguing they belong on your fantasy team. If someone reads this and comments “Uh, it was one start,” I will, well, I won’t do anything, but someone else will down-vote you in the comments, and that will be embarrassing. Don’t do that.

With that out of the way:

Carlos Rodón

Rodón’s run of bad luck in recent years is well-documented. He missed a couple of months in 2018 with a shoulder injury, then had to go under the knife for Tommy John early the following year. He returned to the mound last season, but only for a handful of innings, and he was unceremoniously non-tendered this past winter. Chicago invited him to camp anyway, and while he had a strong spring and won a job in the rotation, he didn’t have a ton of buzz heading into the season. Read the rest of this entry »

Tim Anderson is a befuddling player. Over the last two-plus seasons, he has posted a 133 wRC+ despite a minuscule walk rate (3.3%) that is the third lowest among all players with at least 500 plate appearances, ahead of only slap hitters José Iglesias and Hanser Alberto. That puts a lot of pressure on his ability to produce on contact. So far, so good: In that same time frame, he has a .390 BABIP, tops among all hitters and a full eight points above the next closest player (coincidently, his teammate, Yoán Moncada). The normal expectation is that a BABIP figure that high is unsustainable, and the projection systems tend to agree. The FanGraphs Depth Charts pegged Anderson for a .336 BABIP in 2021 and, correspondingly, a batting line just three percent better than league average.

If Anderson is going to be a productive hitter, then, one of two things needs to happen: He sustains a BABIP that is not just 100 points above the league average but also one of the best figures of all-time; or he improves in plate appearances that do not end with a ball in play. So how likely is either?

Let’s start with the BABIP. Anderson does not hit the ball especially hard. In the last two seasons, he ranked in the 33rd and 40th percentile, respectively, in hard hit rate, according to Baseball Savant. Last season he almost doubled his barrel rate, going from 5.1% in 2019 (23rd percentile) to a career-high 10.1% (65th), but that 2020 figure constituted all of 16 batted balls. Nor has he shown too much selectivity in his career or discriminated against pitches within or near the strike zone, as you can see in the sea of red below.

Prospect writers Kevin Goldstein and Eric Longenhagen will sometimes have enough player notes to compile a scouting post. This is one of those dispatches, a collection of thoughts after another weekend of college baseball, a prospect trade, and minor league co-op action in Arizona. Remember, prospect rankings can be found on The Board.

Kevin’s Notes

Waldy Arias, 3B, Campbell: 3-for-9, 3 BB, K, 2 SB, 2 HBP

If you are here for hardcore draft info, skip to the next paragraph. If you want to have fun for a minute, stick around. Arias is a little junior third baseman at a mid-major program who is slugging .290. Nobody is going to print a magnet with his name on it come July. My question is why does he have so many enemies? With two more hit by pitches over the weekend, Arias has now been hit 16 times in 21 games. That’s nearly once every six plate appearances, which was his exact rate last year, when he got hit 12 times in 15 games. Arias is a pesky slap hitter who crowds the dish. His high front elbow hangs out over the plate and the overall setup reminds me a bit of a mini-Carlos Quentin, who took a fair number of pitches to the body in his career. With access to some of the video and data tools pro teams have, I was able to click a few buttons and watch all 16 HBP. Here are the results:

1. Curveball: Foot
2. Slider: Leg
3. Fastball: Thigh
4. Fastball: Thigh
5. Slider: Foot
6. Fastball: Thigh
7. Fastball: Elbow
8. Fastball: Elbow
9. Slider: Head
10. Fastball: Elbow
11. Changeup: Shoulder
12. Fastball: Back
13. Slider: Elbow
14. Fastball: Elbow
15. Changeup: Hand
16. Slider: Shoulder

Spring games are a blast, a return to baseball after a starved winter of boring transaction rumors. They’re the first chance to see major league players in their natural environment, and the pinnacle of baseball talent facing off against each other (and, inevitably, against some overmatched minor leaguers getting their first taste of the big time). One thing they are most assuredly not, however, are tactical masterpieces. The highest-leverage decision a manager makes is whether to bat their veterans at the top of the lineup so that they can duck out early. In the majors, though, tactical decision-making started when the regular season began. Almost immediately, a neat situation came up, and I’m excited enough to talk tactics that I’m going to give it far more coverage than it deserves.

In the second game of the season, the White Sox were in a pickle. After busting out to a 7–1 lead over the Angels, they’d frittered most of it away. A three-run shot from Albert Pujols here, an Adam Eaton three-base error there, and it was 7–6. A laugher had turned into a struggle for survival.

In the bottom of the eighth, the Angels were again threatening. After Mike Trout led the inning off with a walk, manager Tony LaRussa went to Evan Marshall. Marshall started strong, inducing a pop up from Anthony Rendon and a groundout from Justin Upton. But wait! LaRussa intentionally walked Pujols, putting the go-ahead run on base. What the!?

Tuesday was a busy day in the world of the White Sox. Slugger Eloy Jiménez underwent surgery to repair a ruptured left pectoral tendon, an injury that could sideline him for most of the season and alter the balance of power in the AL Central along the way. In an attempt to help offset the loss of Jiménez and to allow for some potential lineup flexibility in the near term, the team signed free agent infielder Jake Lamb to a major league deal. What’s more, general manager Rick Hahn announced that top prospect Andrew Vaughn has made the Opening Day roster, and could open the season in left field.

The 24-year-old Jiménez, who last year bopped 14 homers while batting .296/.332/.559 (140 wRC+), was injured on March 24 when he caught his left arm on the outfield wall while trying to rob the A’s Sean Murphy of a home run:

Jiménez is expected to miss five or six months following surgery, a devastating blow considering that he was projected to clout 36 homers and provide 3.0 WAR as the team’s left fielder. Alas, it’s not even his first significant absence due to an injury suffered while playing defense. In his 2019 rookie season, he missed over three weeks due to a high right ankle sprain suffered while crashing into an outfield wall in an attempt to prevent a home run, and then another 10 days after colliding with center fielder Charles Tilson and suffering a right ulnar nerve contusion.
