I’ve always been a huge Darin Ruf fan, so getting to write about his 2021 success is a little bit more meaningful to me than it would be for almost any other player. Ruf is the last player I remember my grandfather singling out before he passed away, with the thought that Ruf, then a young prospect in the Phillies system, had the potential to be a productive big leaguer for our favorite team.

That was nine years ago. The Phillies promoted Ruf in late 2012 for his first cup of major league coffee, but he never amassed more than 297 plate appearances in any season for them. The bat was decent — Ruf posted a 105 wRC+ over 833 plate appearances, including a 125 wRC+ during his 2013 rookie season — but poor defensive numbers kept him barely above replacement-level in almost 300 games with Philadelphia. He was traded to the Dodgers in November of 2016, and even before he had an opportunity to make his organizational debut, Ruf’s contract was purchased by the Samsung Lions of the KBO. For three years, he raked in Asia, earning himself a minor league deal with the Giants for the pandemic-shortened 2020 season. (I was pretty excited.) A year later, he’s now the best hitter on a playoff-bound team (Kris Bryant is a notable omission from this list — he has a 119 wRC+ in 128 plate appearances with the Giants so far):

It’s no secret that the Giants have been receiving incredible production across their entire lineup. Their position players have posted a collective 113 wRC+ this season, a figure that ranks second in the majors among teams’ non-pitchers. But even in a lineup filled with players having above-average offensive seasons, Ruf stands out with his .279/.401/.544 slashline and 155 wRC+. That wRC+ ranks seventh in the majors among players with at least 250 plate appearances overall, sandwiched between Juan Soto (156) and Shohei Ohtani (154). That’s pretty phenomenal company, and it inspires two obvious questions. First, how did Ruf become one of the best hitters in baseball, at least this season? And, of course, how sustainable is this?

In 2020, Carlos Santana had a down year. That happens to players all the time, and it’s particularly excusable in the pandemic season. Sixty games can make anyone look bad, and that’s before you get into the vast changes in routine. So while a .350 slugging percentage is obviously concerning, particularly from a first baseman, it’s nothing that you couldn’t hand-wave away by whispering his walk rate or xwOBA to yourself in a soothing voice.

In 2021, Carlos Santana is having a down year. If once is a coincidence, twice is a trend, and this certainly looks bad. The Royals’ problems don’t start at first base, but he certainly hasn’t been the answer there, and I’m skeptical that things will get better. Yes: Carlos Santana has turned into a pumpkin.

I’ll be the first to admit that I don’t understand the Tampa Bay Rays. I don’t understand how they win as many games as they do. They’re definitely good, but it never feels like they should be as good as they are, or recently have been. But at a certain point, if they are consistently better than expected, I’m the one in the wrong and it’s on me to try to understand.

The offense I get. The current American League leader in runs scored is a little over their skis, as they hold that lead despite ranking sixth in on-base percentage and fourth in slugging (they’re fourth in team wRC+ and fifth in OPS). That’s mostly due to the fact that as a team they have greatly improved results with runners on base compared to when they’re empty. That’s more likely luck-related than some kind of mysterious clutch skill they possess, but what the Rays do have is monstrous depth. Nobody in the lineup is going to garner MVP consideration, but their ability to almost never throw out a lineup with dead innings is unmatched in baseball thanks to a roster filled with average or better players. Just look at the Rays compared to the rest of their AL East competition:

I will never not be fascinated by the fact that hitters actually produce negative value when swinging. In my most recent article outlining the struggles of Jarred Kelenic, I briefly discussed this idea. Even in a sea of hitters who are below-average when swinging, Kelenic stands out as being particularly bad when he takes a hack; he’s been worth roughly -6 runs per 100 swings so far this year. And as I noted, the hitters who do the best at limiting the damage on their swings tend to be baseball’s most productive hitters overall. From that research, I found an R-squared of 0.714 between a hitter’s run value when swinging and their seasonal wOBA.

That makes a ton of sense: Hitters who maximize their production on swings — that is, both limiting whiffs and making frequent loud contact — tend to be better hitters overall. But this also got me thinking about the reverse: How does taking pitches influence a hitter’s overall production? From the Kelenic research, I found only a moderate correlation between take value and seasonal wOBA, with an R of 0.422 and an R-squared of 0.178. That’s not to say that better “takers” aren’t better hitters; it just suggests that having extremely high-value takes doesn’t necessarily lend itself to having more success overall. For posterity’s sake, here’s the plot of 2021 hitters’ run value per 100 takes and their seasonal wOBAs. Players on both ends of the wOBA spectrum are highlighted just to demonstrate a few individual examples: Read the rest of this entry »

I wish I could come to you with news about the mass adoption of backup sliders from pitchers across the league. I also wish I could come to you with a shining example of even one player who has perfected the art of the effective mistake. There is no apparent analytical case that comes to mind; it’s largely just a fascination to me — the best hitters in the world swinging through the worst offering a pitcher could imagine throwing. Here’s an example:

Matt Wisler is the perfect guy to have here — someone who throws nothing but sliders making the biggest kind of slider mistake! And yet there are times when it just works. What I want to try to answer is what makes these mistake sliders click without diving into the rabbit hole of pitch sequencing. Are there particular characteristics of movement and velocity that make for better backup sliders?

First, we have to set guidelines on what a backup slider is. You know it when you see it, but it is more broadly defined as something that “hangs” when thrown to a batter of the same handedness. Sliders behave differently depending on whether they’re thrown inside or out, as shown by Eno Sarris on this site a few years back; those away gain almost half a foot of horizontal movement compared to ones thrown inside! Sliders need height to be considered mistakes, but the distinctions in horizontal movement are too vast for an outside-and-up slider to be as bad a mistake as one up but inside. For our purposes, let’s say that a backup slider is anything in the upper third of the strike zone, middle-to-in, in a same handedness matchup. Read the rest of this entry »

Eli Morgan has “a bugs-bunny changeup.” That’s how the 25-year-old rookie right-hander’s signature offering was described when it was suggested that I interview him for the Learning and Developing a Pitch series. Delivered at an average velocity of 75.1 mph, Morgan’s changeup is the slowest among pitchers who have worked at least 40 innings (not including Seattle’s Paul Sewald, who per StatCast has thrown just one changeup all season).

Cleveland’s eighth-round pick in the 2017 draft, Morgan has made 14 starts and has a 5.48 ERA and a 5.01 FIP to go with 68 strikeouts in 67.1 innings. He’s thrown his changeup — a pitch he described in detail this past Sunday — 22.4% of the time.

———

Eli Morgan: “I started out mainly fastball/breaking ball, and then my senior year of high school I began developing my changeup. I’d thrown a splitter — that was my changeup for my first couple years of high school — but I figured that probably wasn’t great for my arm going forward. At the time, there was talk of Masahiro Tanaka having issues with his elbow because of the splitter, and that kind of turned me off of that pitch. I decided to go to a regular circle change.

“When I got to [Gonzaga University] they told me that if I wanted to pitch, let alone be a starter, I needed to have a good changeup. That was a big thing up there, so I started throwing it a lot more and got comfortable with it.

“Because I throw a four-seam fastball, I throw a four-seam changeup. That’s something one of my pitching coaches mentioned: ‘Make sure it comes out with the same seams as your fastball.’ That’s what I went with, and I had pretty good command of it right from the start. Over time, I began getting more movement on it, getting more fade. Read the rest of this entry »

I recently sourced scouting info and wrote about prospects (and rehabbing veterans) who contending American League teams have on the way during the season’s final stretch, players young and old who lurk beneath the big league surface and might yet make an impact on who hoists the Commissioner’s Trophy at the end of the season. Today, I examine the National League.

NL East
I have very little to pass along regarding the Braves. Their Triple-A pitchers on the 40-man (Kyle Wright, Kyle Muller, Tanner Roark) have been up and down throughout the year and they haven’t looked appreciably different since they were last up. Chris Martin and Josh Tomlin went on the injured list very recently and haven’t had a chance to rehab yet. The same goes for Jasseel De La Cruz, who had several rough starts in August before hitting the IL. Yoan López, acquired from the Diamondbacks earlier in the year, has been sitting 95-98 with Triple-A Gwinnett, but his fastball’s lack of movement means it doesn’t miss many bats. His slider is still plus when located properly, though. He’s the lone 40-man member in Gwinnett’s bullpen, though Dylan Lee (throwing strikes, up to 96, lots of in-zone fastball whiffs) has out-pitched him, and Jesse Biddle and Víctor Arano both generate more whiffs than López does. They all might be ahead of him in the pecking order for big league time in case of injury, even if it means making a 40-man move.

The Phillies have a mix of rehabbers and prospects lurking in the minors, with the prospects presenting low-impact/emergency options right now. Young Francisco Morales (who has projected as a reliever for us at FG since signing) has struggled as a starter all year at Double-A Reading, walking 59 in 70 innings pitched. He doesn’t seem to be on the fast track, even in a bullpen role. Read the rest of this entry »

Louis Head has had a storybook season. Without a team during last year’s pandemic summer, the rookie right-hander was working a sales job, his dreams of reaching the big leagues seemingly in the review mirror. Nearly a decade after being taken by Cleveland in the 18th round of the 2012 draft, he thought his career was over. Then the Tampa Bay Rays came calling.

Head was signed off the scrap heap this past February, and on April 25, two days after celebrating his 31st birthday, he made his major league debut. The Katy, Texas native has gone on to appear in 20 games with the Rays since then — he’s also seen action in 24 games with Triple-A Durham — logging a 2.93 ERA and a 3.53 FIP over 27-and-two-thirds innings. His slider has played a big role in his Cinderella ascent. Developed since joining his new team, the pitch has helped fuel one of the better success stories of the 2021 season.

David Laurila: You’re a 31-year-old rookie. How were you able to finally take that final step and reach the big leagues? Was pitching development part of it?

Louis Head: “I think it was mostly about there being an opportunity here. We had some guys get hurt early on in the season, and it opened up some doors for me. That didn’t really happen in the past with other organizations. I felt like I had thrown well in the past, especially for Cleveland, and I could have been a guy they brought up. But those opportunities never happened.

“Development-wise, when I did get here, working with the analytical team, and with [pitching coach] Kyle Snyder, we were really able to develop my slider into a major weapon. Before, it was just kind of a get-me-over pitch. Now it’s a legit put-away pitch, and that’s made a world of difference. Them having confidence in me has been a huge part of my success, as well.”

Laurila: Why were you able to turn the corner with your slider here, and not with Cleveland, the Dodgers, or the Mariners? Read the rest of this entry »

When the Braves signed Ronald Acuña Jr. and Ozzie Albies to phenomenally team-friendly contracts before the 2019 season, two distinct possibilities loomed. First, the team could bank the money they saved and put out a good team at a discounted price. Second, they could reinvest those savings and attempt to put together a great team. Which they chose would say a lot about how the team planned on operating long-term.

The question is no longer open. The Braves have overcome a season-ending injury to Acuña to surge to the top of the NL East, and while the Phillies and Mets continue to nip at their heals, they’re well on their way to a fourth straight division title. They’ve done so thanks to some new young contributors — Austin Riley and Ian Anderson have come into their own this year. They’ve made some savvy signings and trades — Charlie Morton has been their best pitcher this year, and Jorge Soler has been excellent since joining the team.

Now, the Braves are making moves to prolong their stay atop the division. In late August, they signed Travis d’Arnaud to a two-year extension. They followed that up by signing Morton to a one-year deal (both contracts have team options tacked on). Let’s take a look at both of those deals, as well as how they affect the team’s outlook for next year and beyond.

Signing d’Arnaud to an extension — two years and $16 million with a team option for a third year — was hardly an obvious move for the team. He missed the majority of the season after tearing a ligament in his thumb in May. He’s hit well since his return, but even so, his seasonal line works out to an 84 wRC+. Combine that with solid receiving, and the total package works out to a roughly average catcher.

What made the Braves so eager to lock d’Arnaud up? His replacements fell well short of that average catcher bar. On the year, Atlanta’s catcher position has produced -1.4 WAR, the worst mark in the majors. It’s not an individual problem; a huge array of catchers have combined to weigh the position down:

Relative to that mess, d’Arnaud is a huge improvement. That’s not to say that Contreras won’t figure it out, or that Vogt isn’t a capable backup. But for a team with an embarrassment of riches at most positions, giving away so much value at catcher doesn’t make sense. It gets worse: the list of free agent catchers this offseason is nasty, brutish, and short. Yan Gomes and Martín Maldonado are the headliners, and it gets worse from there. Miss signing your target, and you might be in for a long offseason. Read the rest of this entry »

The Wild Card races in both leagues continue to be the source of all the drama down the stretch. There are a handful of teams vying for those last few playoff spots and the competition should go come to the wire. And as we witnessed last weekend, the Giants and Dodgers battling over the top of the NL West should provide a ton of excitement, too.

A quick refresher: my approach takes the three most important components of a team — their offense (wRC+), and their starting rotation and bullpen (50%/50% FIP- and RA9-) — and combines them to create an overall team quality metric. I add in a factor for “luck” — adjusting based on a team’s expected win-loss record — to produce a power ranking.

(All stats through 9/5)

Entering their final head-to-head matchup of the season, the Dodgers and Giants were tied atop the NL West standings and had played to an extraordinary balance in their previous 16 games: they had each won eight games and scored exactly 68 runs against each other. A dramatic 11-inning Giants win on Friday night was a fantastic start to this battle of titans. Alas, the remaining two games in the series were far less climactic, with each team winning a game comfortably. That final series win gives San Francisco home field advantage in case of a potential tiebreaker to decide the NL West at the end of the season. Read the rest of this entry »
