Quick: Who are the best five hitters in baseball this year? Take a quick gander at the leaderboards, if you’d like, before answering. There’s the WAR leaderboard:

That’s not what you want, though, because defense gets involved there. How about a wRC+ leaderboard instead? That should keep the Xander Bogaerts’s and Marcus Semien’s of the world from intruding on our hitting party:

Trout, Yelich, Bregman, Bellinger, and Rendon. That’s a pretty solid five. It’s also missing an obvious name: Yordan Alvarez, quite possibly the best hitter in baseball this year.

Why isn’t Alvarez on the list? It comes down to the tyranny of the qualified hitter. Setting a plate appearance minimum is a reasonable idea: without it, the best wRC+ this year would belong to Oliver Drake, who singled in his only plate appearance. No one wants that, except perhaps Oliver Drake.

That doesn’t mean that it’s always right to ignore everyone who falls short of the qualification minimum, though. Alvarez has 320 plate appearances this year, a far cry from Drake territory. Because he wasn’t called up until June, he won’t qualify for the batting title this year, but that shouldn’t distract you from the fact that he’s one of the best hitters in the major leagues, full stop.

On September 19, 2018, Carlos Santana was in the Phillies’ lineup, playing third base. It was an experiment that sparked speculation about his role in Philadelphia going forward. After all, he had just signed a three-year, $60 million contract. But after Rhys Hoskins had one of the worst defensive seasons by a left fielder this decade, it was clear that Santana’s usage would need to be adjusted. Having him play first — thus relegating Hoskins to the outfield — would not work long term, especially for a team trying to contend.

Santana’s brief stay in Philadelphia was mixed. He drew walks in 16.2% of his plate appearances, hit for power at about his then-career-average, and was about average defensively. With that information, you’d probably think that Santana had a good year, but reality was different. He was BABIP’d to death; no qualified hitter in 2018 posted a lower BABIP than Santana’s .231. His slash sat at .229/.352/.414 with a 108 wRC+, a decent-yet-unspectacular season. He also made headlines this past March when it was reported that, near the end of the 2018 season, he had smashed a clubhouse TV after witnessing his now-former teammates playing Fortnite during games.

The Phillies went on to have a memorable offseason, to say the least. They signed Bryce Harper, Andrew McCutchen, David Robertson. They traded for J.T. Realmuto and Jean Segura. Once all of the dust settled, Carlos Santana was no longer wearing red and white pinstripes. The seemingly tumultuous relationship lasted one season. Santana was back in Cleveland, the same place where he had spent the first eight seasons of his major league career. Read the rest of this entry »

The Marlins are a franchise with exactly two modes: brief moments of contention, and long stretches that punish anyone who would want to root for them. Miami is currently in the latter mode. Parity’s alive and well in the National League, with 14 of the league’s 15 teams spending significant time in 2019 playing the role of legitimate wild card contenders. The 15th team was these Marlins, the Star Trek redshirt of the Senior Circuit.

The Setup

The troubling truth for Marlins fans is that most winters’ offseason activity involves guessing who the team will get in return for its best players who are approaching free agency; if the 2018-2019 winter offered less consternation for fans, it’s only because the team had already traded away their entire outfield the year before. Without the ability to replace their lost stars with effective minor league talent — the formula that has kept the Rays frequent contenders despite their part-feigned penury — there was little chance the Marlins would be competitive enough to justify hanging on to J.T. Realmuto. In fairness, a lot of the blame for this is due to the previous regime, which made moves like trading away Chris Paddack and Luis Castillo for Fernando Rodney and Dan Straily.

Two years away from free agency, and with the Marlins unlikely to be competitive during that stretch, it was all but assured that Realmuto, an All-Star for the first time in 2018, would start the season in another city. A week before spring training started, he departed for the Phillies in exchange for Sixto Sanchez, Jorge Alfaro, Will Stewart, and, in a surprising move for a Marlins team to make, the right to spend more money in the form of international bonus space.

Christian Yelich won NL MVP honors while leading the Brewers to a division title and within one win of a trip to the World Series last year, but hopes for repeating that magic took a severe blow on Tuesday night. In the first inning of the Brewers’ game against the Marlins in Miami, the 27-year-old right fielder fouled a pitch off his right kneecap and was forced from the game. In the aftermath of the team’s 4-3 victory, general manager David Stearns told reporters that Yelich had fractured the kneecap and will be out for the remainder of the season, a crushing blow to a team that has overcome a slew of injuries to win five straight games and climb to within one game of the second NL Wild Card spot.

Ouch. Ugh. F***. A player with a reasonable claim as the NL’s best is down for the count as far as 2019 goes, and while thankfully it’s not an injury with career-altering ramifications, right now there’s no joy in Mudville or Milwaukee. This completely sucks.

Facing righty Elieser Hernandez, Yelich fouled a 1-1 slider squarely off his right knee, crumpled to the ground, and remained there for several minutes while being tended to by Brewers athletic trainer Rafael Freitas. He could not complete the plate appearance (pinch-hitter Trent Grisham completed the strikeout, which was charged to Yelich) and limped off the field under his own power (you can see the video here).

Stearns said that Yelich would be flown back to Milwaukee to meet with team doctors and determine whether surgery would be necessary and what the prognosis would be going forward. He praised his star slugger, saying, “Look, I think first and foremost, we feel awful for Christian. This is a guy who has carried us in a number of ways over the last two years. He could have been two and a half weeks away from a repeat Most Valuable Player Award. That’s where our thoughts go first.” Read the rest of this entry »

I confess that I haven’t watched many Marlins games this year. The team is projected to have the third worst record in baseball, potentially losing 100 or more games for just the third time in organization history. They average fewer than 10,000 fans per home game, the lowest in the league in 2019, which would be an all-time low, surpassing the 2018 season. It’s been a bumpy ride for Don Mattingly’s rebuilding Miami club.

But the Marlins do have some interesting players who are capable of doing interesting things not many other players are capable of doing. After Caleb Smith’s solid outing this past weekend, I spent some time perusing Statcast and discovered that, among left-handed pitchers who have thrown a minimum of 50 four-seam fastballs in 2019, Smith’s has the third most horizontal movement in the game. Right behind him is his teammate, Adam Conley. One spot ahead of him is Chris Sale. And one spot ahead of Sale, leading all 113 lefties in this sample in horizontal movement, is Smith and Conley’s teammate Jarlin Garcia.

Three of the top four left-handed big leaguers in four-seam horizontal movement all pitch for the Marlins.

That piqued my interest. In 2018, Garcia was one of the worst pitchers in baseball, carrying a -1.3 WAR and 6.37 FIP in 66 innings pitched. His xwOBA-against and xSLG-against were both in the first percentile in the league. In 2019, Garcia’s strikeout rate is up, his walk rate is down, and as of this writing, he has contributed 0.4 WAR and has a 3.79 FIP. What seems to be the likeliest cause of this improvement? His fastball’s horizontal movement was still 98% better than league-average last year, but its value was -1.57 wFB/C. This year it is 110% better than league average and its value has been 0.86 wFB/C. What changed more than his fastball movement, however, was his slider movement and usage:

With president of baseball operations Dave Dombrowski fired and the team’s playoff odds heading into skim milk territory, the Red Sox have effectively thrown in the towel on 2019. Who will be charged with cleaning up the situation — a competitive roster that will nonetheless have significant holes to fill, a massive payroll that could limit their ability to do, a depleted farm system, and sky-high expectations nonetheless — remains to be seen. One thing is certain, however: at or near the top of the incoming executive’s to-do list will be figuring out how to handle Mookie Betts‘ pending free agency following the 2020 season. For as tempting as it may be to trade him before he walks away, the Red Sox could be making a serious mistake.

Betts, who will turn 27 on October 7, is in the midst of another fine season, if not one that measures up to last year’s high standards. Through Monday, he’s hitting .290/.388/.522 with 27 homers, 14 stolen bases, a 133 wRC+, and 6.1 WAR. Among American League players, his on-base percentage (fourth), WAR (fourth), and steals (10th) rank among the top 10, but for as impressive as that may be, it’s a marked contrast to 2018, when he led the AL in batting average (.346), slugging percentage (.640), and WAR (10.4) while placing second in on-base percentage (.438) and wRC+ (185), fourth in steals (30), and ninth in homers (32) en route to winning AL MVP honors in a landslide and helping the Red Sox to a championship. Not only was that 10.4 WAR higher than any player’s — even Mike Trout’s — since Barry Bonds’ 11.9 in 2004, but Betts posted that mark during his age-25 season, younger than any other 10-win player from the post-1960 expansion era save for Trout.

By that yardstick, Betts’ 2019 looks like something of a disappointment, though he has dug his way out of an early-season funk that saw him hit an unremarkable .243/.375/414 (108 wRC+) in May and June. Since July 1, he’s hit .329/.397/.616 for a 155 wRC+ and 3.3 WAR, the last of which is fifth in the majors in that span behind only Alex Bregman (3.8), Trout (3.7), Anthony Rendon (3.5), and Ketel Marte (3.4). Prorate that performance to his season total of plate appearances (670) and that’s 7.8 WAR with 18 games still to play — an MVP-caliber season in most years. Read the rest of this entry »

Pitchers learn and develop different pitches, and they do so at varying stages of their lives. It might be a curveball in high school, a cutter in college, or a changeup in A-ball. Sometimes the addition or refinement is a natural progression — graduating from Pitching 101 to advanced course work — and often it’s a matter of necessity. In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.

In this installment of the series, we’ll hear from three pitchers — Chance Adams, Domingo German, and Nick Pivetta — on how they learned and developed their curveballs.

———

Chance Adams, New York Yankees

“When I was in college my pitching coach was Wes Johnson, who is now with the Twins. He taught me my curve. For awhile it was kind of slurve-slider, then it went to a curveball, and now it’s kind of slurvy again. But it’s interesting, because when I got [to Dallas Baptist University] it was, ‘OK, I throw it like this,’ and he was like, ‘Well, have you tried spiking it?’ My curve was moving, but it wasn’t sharp, and I was like, ‘No, not really.’ Spiking it was uncomfortable at first, but after I got used to it, it was pretty interesting. It started moving better.

“My pointer finger is off the seam, with just a little pressure on the ball. Wes said to try spiking it and see what feels good, so I worked on it with this much spike, that much spike. Even now, the spike kind of varies for me; I’ll move it back or forward for comfortability, but also movement-wise. Sometimes it’s sharper when it’s more spiked. It kind of depends on the day, and if I’m controlling it or not. Read the rest of this entry »

“I don’t do anything with my life except romanticize and decay with indecision.” – Allen Ginsberg

There’s no team harder for me to get a read on than the Kansas City Royals. The afterglow of the 2015 World Series has long faded, and attendance is falling back towards levels you might expect for a baseball team playing in Florida. Given the team’s inconsistent statements concerning the organization’s present — and the accompanying moves in harmony with that theme — I’m not sure whether Kansas City is incompetently rebuilding, incompetently retooling, or incompetently competing. Short of a sudden change in organizational focus, the Royals’ main task is to mark the time between the end of one Pat Mahomes season and the start of the next one.

The Setup

After two years of treading water post-championship, 2018 was the year that everything came crashing down. That that season was going to be a dreadful one was largely preordained, prophesied by the team’s contract situations. After winning 80 games in 2017, players worth more than half of the team’s WAR (13.0 wins out of 24.7 total) hit free agency, and there was little hope of one of the league’s weakest farm systems or a fat ownership wallet making good on those losses. Mike Moustakas returned to Kansas City after receiving scant interest in free agency and Alcides Escobar was re-signed for no fathomable reason, but there was little reason to believe that these moves were enough to keep the team wild card pretenders into August.

The 2018 Royals finished with 104 losses and it seemed as if they were finally ready to embrace a full-blown rebuilding process. After all, the Royals spent the summer trading most of their veterans who could fetch some kind of player in return; Moustakas, Kelvin Herrera, Jon Jay, Lucas Duda, and Drew Butera were all dealt. A rebuilding team hardly needs a dedicated pinch-runner and Terrance Gore was traded to the Cubs. Even Escobar started to have his playing time curtailed in just his third consecutive year of near replacement-level production. Sure, players like Alex Gordon and Ian Kennedy stayed put, but they were largely immovable anyway. Read the rest of this entry »

For the most part, a pitcher’s FIP is going to line up pretty well with his ERA over the course of a season or a career. There are 240 starting pitchers with at least 1,000 innings over the last 25 years and all but seven of them have a FIP within half a run of their ERA. Even over the course of an individual season, we typically see most pitchers with an ERA and a FIP around the same mark. Over the last 25 seasons covering more than 3,500 individual pitching seasons of at least 100 innings, the r-squared is .61. This season, there are over 100 pitchers with at least 100 innings; the graph below shows their FIPs and ERAs (all stats are through September 5):

With the exception of Antonio Senzatela way up top, we see a pretty distinct pattern moving up and to the right. Within this cluster of players, there isn’t a perfect relationship. A perfect relationship would make one of the stats duplicative and useless. ERA and FIP both measure results on the field, with ERA accounting for the players who cross home plate after getting on base when the pitcher was on the mound (and the trip home wasn’t made possible by an error), while FIP measures strikeouts, walks, and homers. Every year, a good number of pitchers have an ERA higher than their FIP and vice versa. As far as explaining the difference between the two numbers using readily available statistics goes, BABIP and left-on-base percentage explain much of the gap between the two numbers.

That LOB% would explain some of the gap makes a lot of sense given that stranding more runners than expected is going to keep a pitcher’s runs allowed (ERA) lower than his general performance (FIP). We can see the relationship between ERA-FIP and LOB% for pitchers this season below:

Without delving into whether there’s a skill involved in stranding runners (though better pitchers tend to have higher LOB% due to just being better at getting outs generally), we can see that the more runners stranded and the higher the LOB%, the more likely it is that a pitcher’s ERA is going to be lower than his FIP. The relationship over the past 25 years for individual seasons is stronger than the one above, with an r-squared of .56, but even over just one season, the pattern is apparent. What we are dealing with above is sequencing and what happens when runners are on base compared to overall performance. Generally speaking, pitcher’s perform similarly with runners on base and with the bases empty, with a slight increase in FIP for everyone with runners on base:

This isn’t to say that some pitchers aren’t worse pitching from the stretch, or that some pitchers don’t change their strategy to more effectively get batters out with runners on base. But generally speaking, pitchers perform a little bit worse with runners on base, though in a fairly uniform pattern as seen in the graph above. Unless you are Doug Davis, Scott Kazmir, Jeff Suppan, or Iván Nova, then with runners on base, you were within half a run with runners on base or worse.

We’ll get back to LOB% in a minute, but first, we should address BABIP. Here’s the relationship between BABIP and the difference between ERA and FIP:

The relationship isn’t as strong as LOB%, but with an r-squared of .41 this season, we can still see a pattern. Over 25 years of individual seasons, the r-squared is .52, nearly the same as LOB% over the same time. While we know that pitchers exert some control over the quality of their contact, over 90% of pitchers with at least 1,000 innings since 1995 are between .270 and .310, and 65% of pitchers are between .285 and .305 (around 10 hits per year at the edges), so even at the extremes we are talking about maybe three or four extra hits per month. That’s not nothing, but over long stretches of time, we generally see the seasonal outliers get closer to their peers.

As for just how much BABIP and LOB% capture the difference between ERA and FIP, the answer is they account for the great majority of it. I took all individual seasons from 1995 through last season and ran them through a multiple regression calculator to come up with a formula for predicting the difference between ERA and FIP. The r-squared for the formula for the 3,400 seasons was .75, so BABIP and LOB% are doing a huge amount of the heavy lifting when it comes to explaining the difference between ERA and FIP. I put the same formula into this year’s numbers and this is how they came out:

We still see some outliers, but overall, the formula did a very good job predicting the difference between ERA and FIP using LOB% and BABIP. There are a few outliers. Dakota Hudson jumps out, but his larger ERA-FIP discrepancy is pretty easily explained by 15 unearned runs. If he had a more normal five earned runs, the difference would be under a run and he’d be in the big group with everybody else. Justin Verlander, on the other hand, appears to be breaking the formula entirely. To see how, here are 3,500-plus individual pitcher seasons with over 100 innings since 1995, and their LOB% and BABIP:

Quite simply, Verlander is having one of the most unusual seasons we’ve ever seen, with the highest LOB% and lowest BABIP in the last 100 years in the same season. As we can see above, there is some correlation between LOB% and BABIP, with an r-squared of .2, but that’s not as strong as either statistic’s relationship with FIP-ERA, and a pitcher’s BABIP’s relationship with his team’s BABIP is around the same strength, with team BABIP and team UZR having a slightly stronger relationship.

While there is certainly a case to be made that pitchers have control over the quality of contact they yield to some extent — no one would deny the existence of groundball pitchers or fly ball pitchers — BABIP doesn’t even necessarily measure contact quality. It counts every batted ball in the park as either a hit or an out, doesn’t include homers at all, and it varies greatly from year to year. Even xwOBA, which includes homers and dials in on the quality of contact, has difficulty finding a relationship year over year on contact. Looking just at in-season results, wOBA on contact has a difficult time becoming reliable.

It’s only natural to want to find a reason why a pitcher’s ERA and FIP are so different, and for that reason to be related to something the pitcher is or isn’t doing. Unfortunately, that isn’t always likely to be the case. In any single season, there are going to be outliers due to the relatively small sample of plate appearances we are dealing with, and almost all of the difference between ERA and FIP can be explained by BABIP and LOB%. While not all of a pitcher’s BABIP and LOB% are due to a pitcher’s defense, sequencing luck, and just general good fortune, a decent amount is just that. Baseball is a team sport and defenses play a large role in run prevention. While it isn’t always easy to admit, luck plays a role as well.

In terms of notoriety, Nestor Cortes Jr. barely registers a blip on the national radar. That’s not meant as a slight to the 24-year-old lefty. It’s just that when you play for a star-studded team — in baseball’s largest market, no less — it’s hard to make a name for yourself as a rookie reliever. More specifically, a soft-tossing rookie reliever who lasted until the 36th round of the 2013 draft.

He’s probably the most unique member of the 2019 New York Yankees. Born in Surgidero de Batabano, Cuba, and raised in Hialeah, Florida, Cortes has a little Luis Tiant in his windup — Oliver Perez would be a contemporary comp — and his lack of giddy-up is more of a wrinkle than a scar. He’s averaging better than a strikeout per inning with a heater that lives south of 90.

“I’m more of a deception pitcher,” said Cortes, whose 5.13 ERA is accompanied by an unblemished 5-0 record. “The cliche is that everybody throws 95 now, but what I do is try to mess up timing. The multiple windups I use, the spin rate on my fastball, hiding the ball well before I go to home plate… I try to abide by all of that. I cherish that I can use those things to my advantage.”

Those attributes are on display in The Bronx because the Orioles opted not to keep him. Cortes was a Rule 5 pick by Baltimore in December 2017, but after appearing in just four games last April he was returned to his original club. He spent the remainder of the season in Triple-A with the Scranton/Wilkes-Barre RoughRiders. Read the rest of this entry »
