“He made a mistake, and Trout made him pay.” No doubt you’ve heard some version of that sentence countless times. Maybe the announcers called it a hanging slider, or a meatball, or any number of other ways of describing a poor pitch. But what exactly does it mean, and how can you know one when you see one?

I’ve discussed that question with my colleagues frequently, but we’ve never come up with a satisfactory answer because the pitches that get classified as mistakes aren’t always intuitive. Sometimes a pitcher hits the inside edge of the zone, only for a hitter sitting on just such a pitch to unload on it. Sometimes a backup slider ties up the opposing hitter. There’s bias to these observations, too: You’re far more likely to remember a pitch that gets clobbered for a home run than one that merely results in a take or a loud foul.

I still don’t have a definitive answer. I did, however, make an attempt at answering one very specific form of the question. One pitch that really does feel like a mistake, regardless of intent and irrespective of circumstance, is a backup slider over the heart of the plate. Spin a slider wrong, and it morphs into a cement mixer, turning over sideways without movement. Leave one of those middle middle, and the result is a slow and centrally located bat magnet.

Pitch shape is a sticky trait. And I don’t mean sticky in the spider tack way; rather, sticky in that the trait would hold year over year without volatile fluctuation. When evaluating a small sample, teams and analysts must decide what traits are worth betting on and which are just potential blips in a player’s profile. Depending on the team, there are varying levels of confidence in assessing that predicament and turning it into action. In the case of the Dodgers, there is a demonstrated confidence in their assessments that leads them to take on some risk, but they have no issue in turning that risk into a realized success.

The latest instance of that came on Tuesday, with Los Angeles reportedly agreeing to a contract with veteran pitcher Shelby Miller. The deal is a major league contract, assuring that he’ll be a contributor in the Dodgers’ bullpen from day one. That probably came as a big surprise. Miller hasn’t pitched that much in the last five years after struggling with injuries and sub-par performance. But he isn’t the same pitcher he once was, which we saw in his brief 2022 stint with the Giants, where he posted a 26.1% whiff rate on 57 fastballs thrown and showed off a semi-new slider that made an appearance in 2021 but seems to have been refined.

Michael Wacha is, in many ways, the same pitcher who broke into the big leagues with the St. Louis Cardinals in 2013. The changeup is still his best weapon, and his fastball velocity has remained in the 93–95-mph range throughout. The 31-year-old right-hander has changed teams a few times, but he’s largely kept the same identity.

There have been tweaks to his repertoire and pitch usage. That’s inevitable over the course of what has been a 10-year career, one that will continue will a team yet to be determined. Following seven years as a Cardinal and subsequent one-year stints with the New York Mets, Tampa Bay Rays, and Boston Red Sox, Wacha is now a free agent. He’s hitting the open market on a high note; in 23 starts comprising 127.1 innings last season, the Texas A&M product went 11–2 with a 3.32 ERA.

Wacha discussed his evolution as a pitcher on the final day of the 2022 regular season.

———

David Laurila: To varying degrees, all pitchers evolve. How many times would you say you’ve changed over the years?

Michael Wacha: “From my rookie year, I’d probably say… a couple of times? But I don’t know. I mean, each year I’m trying to work on something different to help out my repertoire, to bolster it or make it better. So it’s kind of hard to say, but there have been a couple of changes.”

Laurila: Can you give any examples? Read the rest of this entry »

The Nationals aren’t going to make the playoffs in 2023. They probably won’t even sniff .500; unsurprisingly, the team that traded Juan Soto along with everything that wasn’t nailed down this past season isn’t quite ready to compete for division titles. That doesn’t mean they shouldn’t try to get better, though – when the next generation of Nationals stars reaches the majors, the team would prefer to have some major league pieces already in place, mirroring the vaunted Cubs and Astros rebuilds of the 2010s. To that end, the Nationals made a signing I absolutely love yesterday, snagging Jeimer Candelario on a one-year deal worth $5 million, with $1 million in incentives.

Before the 2022 season, no one would have believed you if you told them Candelario would be a free agent this winter. In 2020 and ’21, he hit a combined .278/.356/.458, good for a 125 wRC+. He backed that up with decent defense at third base; all told, he looked like a comfortably above-average player carried by his bat. Then came 2022, an abject disaster; over 124 injury-interrupted games, he hit .217/.272/.361 and saw pretty much every statistical indicator tick downwards. The Tigers chose to release him rather than go through arbitration, which MLB Trade Rumors estimated at roughly $7 million.

For the 2020 and ’21 versions of Candelario, that would be a bargain. Quite frankly, I still think it would make sense after his poor 2022 season. The Tigers didn’t share my assessment, valuing the combination of money and roster space as more important than retaining his services. I’m not quite sure I understand it – they currently have two open spots on their 40-man roster and no in-house third baseman – but their loss was Washington’s gain. Read the rest of this entry »

The White Sox dipped into the free-agent pool this week with their first significant move of the offseason, agreeing to terms with righty Mike Clevinger on a reported one-year, $12 million deal. For the soon-to-be-32 Clevinger, it represents an opportunity to reestablish himself as a reliable mid-rotation starter after struggling to do so with San Diego in his return from his second Tommy John surgery in 2022. For the White Sox, it means adding a relative unknown with some upside to a talented and extremely right-handed rotation featuring 2022 AL Cy Young finalist Dylan Cease, a pair of veterans in the possible last years of their contracts in Lance Lynn and Lucas Giolito, and a 26-year-old Michael Kopech, who is trying to stay healthy for a full season himself after an early-career Tommy John surgery of his own.

The move comes as a bit of a surprise this early in the offseason, with much of the starting pitcher market yet to be sorted out. The reported $12 million value of the contract is a chunk of change higher than both our crowdsourcing and Ben Clemens predicted at $8 and $9 million, respectively. There’s a lot of starting pitching out there in November, including a handful of veterans coming off strong years that might be available for a one-year contract at or around $12 million. Corey Kluber contributed a productive season in Tampa this year, as did Michael Wacha in Boston, though he may require a second year of commitment. Andrew Heaney has generated enough buzz early that he might push that budget, but he’s available. Johnny Cueto was the second most valuable pitcher on these very same White Sox, with 2.4 WAR over 158.1 IP, but at age 36 would likely come at a similarly reasonable rate. So why did Chicago instead jump the market for Clevinger? Read the rest of this entry »

Falling behind in the count puts an enormous amount of pressure on the pitcher. It’s in his best interest to throw a strike and retake control, but knowing this, hitters are more likely to swing. Aiming outside the zone is dicey: It’s great if the hitter bites but disastrous if he doesn’t, and the risk generally outweighs the reward. A pitcher would ideally execute a borderline strike that hitters can’t help but pass up, but that’s easier said than done. Navigating this situation is tricky, and just from a numbers perspective, whoever’s on the mound is pretty much always in trouble. The question isn’t “can the pitcher emerge victorious,” but rather, “Can he escape with minimal harm?”

For decades, pitchers have relied on their fastballs to fight these uphill battles. Part of that is because long ago, some of them actually believed throwing a slider or another secondary pitch wasn’t very manly. You ain’t tough unless you blow a 2–0 heater by your opponent, I guess. But really, it’s because a fastball is the pitch a majority of pitchers are comfortable with, and it’s the one they can most reliably lob in for a strike. If your goal is to equalize the count, why risk using an erratically moving curveball to achieve it?

Unfortunately for those old-timey hurlers, they’re probably rolling in their graves at the apparent cowardice of modern pitchers. Rather than adhere to axioms, pitchers today are challenging notions of what’s “right” or “wrong” in pitching, aided by advancements in pitch- and body-tracking technology. One example of such sacrilege is the continuously increasing rate of breaking balls — sliders, curveballs, and the like — thrown in disadvantageous counts:

It’s true that breaking ball usage is up no matter the count or situation, but I find it particularly interesting that the trend remains strong even when pitchers fall behind. The name of the game is optimization. If teams didn’t think opting for breaking balls when behind in the count granted them an advantage, we wouldn’t see this happening. Granted, just because teams do something doesn’t necessarily means it’s effective, but a league-wide jump of eight percentage points in pitch usage is significant and worthy of investigation.

The 40-man roster deadline led to the usual squall of transaction activity, with teams turning over portions of their rosters in an effort to make room for the incoming crop of young rookies. Often, teams with an overflow of viable big leaguers will try to get back what they can for some of those players via trade, but because we’re talking about guys straddling the line between major league viability and Triple-A, those trades tend not to be big enough to warrant an entire post.

Here I endeavor to cover and analyze the moves made by each team, division by division. Readers can view this as the start of list season, as the players covered in this miniseries tend to be prospects who will get big league time in the next year. We’ll spend more time discussing players who we think need scouting updates or who we haven’t written about in the past. If you want additional detail on some of the more famous names you find below, pop over to The Board for a more thorough report.

The Future Value grades littered throughout these posts may be different than those on the 2022 in-season prospect lists on The Board to reflect our updated opinions and may be subject to change during the offseason. New to our thinking on this subject and wondering what the FVs mean? Here’s a quick rundown. Note that because we’re talking about close-to-the-majors prospects across this entire exercise, the time and risk component is less present here and these FVs are what we think the players are right now.

One of the most common arguments against the designated hitter coming to the National League was that it would cause a decline in pinch-hitting, therefore removing an element of strategy from the game. It was inevitable, after all, that pinch-hitting opportunities would dry up without pitchers to sub out. Lo and behold, offensive substitutions in the NL decreased by more than 60% from 2021 to ’22, with teams sending just 1,647 pinch-hitters to the plate this past season, compared to 4,438 the year before.

Thankfully, for those of us who missed the glorious art of pinch-hitting, there was still a way to get our fix: the San Francisco Giants. They used 258 pinch-hitters in 2022 — 95 more than the team with the next-highest total, the Athletics. It’s also a whopping 222 more than the team with the fewest pinch-hit plate appearances, the Rockies. It’s so many pinch-hitters, in fact, that the Giants wouldn’t have looked out of place in the pitcher-hitting era. They used more bats off the bench in 2022 than one NL team, the Cardinals, used in 2021. In the first full year of the universal DH, the Giants were still pinch-hitting at a pre-DH rate.

No National League team benefited more from the universal DH this year than the Philadelphia Phillies. The torn UCL Bryce Harper suffered in April would’ve been a season-ending injury for any Phillies outfielder from 1883 to 2019, but Harper was able to get a platelet-rich plasma injection, grit his teeth, and DH the rest of the way. You’re probably familiar with what ensued: Philadelphia’s first playoff berth in 11 years, numerous loud home runs and memorable GIFs, “swing of his life,” and so on and so forth.

Unfortunately for Harper, eventually someone had to open up his throwing arm and see precisely what had gone wrong in there. Last week, Dr. Neal ElAttrache — there’s a name you never want to see in a news story about your team’s best player — broke out his scalpel and went spelunking.

For months, Harper and the Phillies settled into a position of anxious uncertainty; perhaps the damage to his elbow wouldn’t be so bad. An Opening Day start in right field was probably too much to ask for, but maybe he could rehab in the offseason and get back to throwing by mid-spring. This is a situation that ought to be familiar to anyone who’s sat in their mechanic’s waiting room and hoped that the phrase “blown head gasket” would not be part of the day’s conversation.

Unfortunately, Dr. ElAttrache was forced to perform another dreaded proper noun: Tommy John surgery. In short, you can take that depth chart with Harper in right field and throw it right in the trash. Now, the party line is that Harper will return to the lineup as a DH around the All-Star break, and maybe start playing the outfield again by the end of the 2023 regular season.

Financial implications aside, how the Oakland Athletics fared in the August 1 trade-deadline deal that sent Frankie Montas and Lou Trivino to the New York Yankees in exchange for Cooper Bowman, Luis Medina, JP Sears, and Ken Waldichuk won’t be known for at least a few more years. Two of the players who headed west made their big-league debuts last summer, while the others finished their respective seasons in Double-A and High-A. The extent to which the foursome goes on to thrive — or flop — can’t be predicted with any degree of certainty.

David Forst is understandably bullish on the quartet. Three-plus months after he pulled the trigger on the trade, I asked Oakland’s GM what he found appealing about each acquisition.

“We think Waldichuk has a chance to be a top-of-the rotation arm, and we certainly saw glimpses of that in the big leagues,” Forst said of the 24-year-old left-hander, who is No. 69 our Top 100 Prospects list. “With him, it’s the physicality, the fastball command, and the swing-and-miss he gets with three different pitches. I think Ken has a huge upside.

“Upside is the whole conversation with Medina,” continued Forst. “Huge arm, huge fastball. Whether he remains a starter or not, we’ll see. He’s pitching really well in the Dominican [Winter League] right now. I know that he wants to remain as a starter, but he has to improve his command.” Read the rest of this entry »
