First, a bit of history:

The major league annals include just two players born in Slovakia. One of them is Elmer Valo, an outfielder for six teams from 1940-1961 who hailed from the village of Rybnik. The other is Jack Quinn (born Johannes Pajkos), a pitcher for eight teams from 1909-1933 who drew his first breaths 333 kilometers away in Štefurov. Both came to the United States at a young age, their families settling in the Pennsylvania.

Adam Macko hopes to follow in their footsteps, albeit via pathways. A native of Bratislava, Slovakia, Macko moved to Stoney Plain, Alberta, Canada when he was 12 years old — a year in Ireland bridging the Atlantic journey — and then to the southern part of the province where he spent three years at the Vauxhall Baseball Academy before being selected by Seattle in the seventh round of the 2019 draft.

Profile-wise, Macko is more finesse than power, albeit not by a wide margin. The 20-year-old called himself “a command lefty” when offering a self scouting report, but that belies a velocity jump that saw him clocked as high as 97 mph in spring training. In his first start of the season, Macko sat 92-96 with his four-seamer while hurling four scoreless innings for the Low-A Modesto Nuts. Mixing and matching effectively, the southpaw set down seven Stockton Ports batters on strikes. Read the rest of this entry »

When we last checked in on our partially crowd-run Out Of The Park Baseball team, the season wasn’t yet underway. We spent the offseason building pitching depth after a nightmarish injury season left us with a bullpen made of duct tape and late-season callups. In an effort to avoid a recurrence of that problem, we came into this season with pitching depth that could best be described as excessive.

Even after trading Eric Lauer (more on that in a second), the team went seven deep on starters: Brandon Woodruff, Kevin Gausman, Collin McHugh, Freddy Peralta, Adrian Houser, Corbin Burnes, and Brent Suter are all at least candidates for a rotation spot. Surely, I (and you) reasoned, that depth will sustain us even if injuries become a problem again.

Good news: through 42 games, injuries haven’t been a problem. Our top five starters have made all 42 starts, though virtual Adrian Houser is headed for the bullpen unless he turns things around quickly; his 10.64 ERA isn’t reflective of his true talent, but his 9.25 FIP isn’t exactly a great sign. He’s become a two-pitch pitcher in this simulation, so a swap with Suter might suit both.

Pitchers are always looking to chip away at the platoon advantage. Two of the most common weapons in doing so are the changeup and curveball. The former fades away from opposite-side batters and from the barrel as the bat whips through the zone. Most of a curveball’s movement, meanwhile, is vertical; no matter the handedness of the batter and corresponding bat path, the pitch can duck under the bat as the batter makes contact. Sliders, though, generally have a large platoon split, to the detriment of the pitcher, as they move more horizontally relative to vertically and toward the pitcher’s glove side. This leads the ball towards the barrel of an opposite-handed hitter, giving him more of an opportunity to make contact.

Cutters are interesting in this regard. Given the movement of the pitch, you would expect it to have significant platoon splits like a slider. The ball moves toward a pitcher’s glove side, albeit generally not as far as a slider; an opposite-handed hitter would have a better chance putting the barrel on it. But this is not the case, according to research from Max Marchi done back in 2010, as he found that cutters were in the middle of the pack with respect to pitch-type platoon splits. It still had more favorable splits when the batter had the platoon advantage, but that is the case for all pitches in general.

So why does the cutter not have much of an effect on the platoon advantage despite its break? As MLB.com explains it, the magnitude of the horizontal break is subtle enough to catch a hitter expecting a four-seamer off guard. Thus, when he swings, the movement of the pitch forces the batter to fight it off his hands and either induces weak contact or breaks the bat altogether. My thesis was that players are turning to the cutter because of these neutral platoon splits, as heavily using a pitch that works well to hitters from both sides makes you harder to predict.

I love wonky early-season slash lines, the kinds of combinations that make you scratch your head and consider what exactly had to happen to get to this point. It’s pretty easy to put Yasmani Grandal’s start in that category: Through 22 games and 91 plate appearances, Grandal is hitting .113/.378/.242, slugging two homers and posting a… 102 wRC+?!?

Yes, you read that correctly. Through games on Sunday, Grandal has just seven hits and has the worst batting average among players with at least 80 trips to the plate. And yet he’s also managed to be an above-average hitter by wRC+. There’s truly some wild stuff going on here.

Of course, none of this is sustainable. Grandal has faced some pretty horrible BABIP luck, and as Dan Szymborski noted in his article yesterday, he is the fourth-largest underachiever in actual BABIP (.119) versus ZiPS-developed zBABIP (.261). Plug that figure into his balls-in-play total and you’d find that Grandal should have more than 13 hits this season, giving him a more-respectable-though-still-not-great .210 batting average.

But what is most interesting about Grandal’s start isn’t that he’s faced such poor BABIP luck; it’s that he has still managed to be a productive hitter in spite of it. Grandal has walked a whopping 27 times to start the season, a near-30% walk rate and a figure that leads baseball by a rather healthy margin. As of this writing, Max Muncy is the only other player who has amassed more than 50 plate appearances with a walk rate above 20%, and he’s still more than six points behind Grandal. Since 1901, Grandal’s 27 walks in his 22 games are tied for the 16th-most walks in any player’s first 22 to begin a season, but he’s one of just five players to do that while also batting under .150.

First base is an offense-first position. Sure, it’s great to have a first baseman who is handy with the glove and can scoop errant throws, but by and large, it’s a position for sluggers. Even though the position supplied both of last season’s MVPs — Freddie Freeman and José Abreu — it’s production doesn’t hold up as strongly as it has compared to previous years. From 2018 through the 2021 season thus far, first basemen have averaged a 108 wRC+ compared to an average wRC+ of 115 over the 2000-17 seasons.

There are plenty of teams suffering from lackluster production at first base but I want to highlight two of them: the Milwaukee Brewers and the Tampa Bay Rays. The Brewers have managed a measly 68 wRC+ and -0.5 WAR, with contributions mostly from the duo of Keston Hiura (who is now in Triple-A) and Daniel Vogelbach. The Rays have been a bit better with a wRC+ of 82 and -0.1 WAR. These aren’t the worst teams in the majors at first base but they do share something in common; they once had Jesús Aguilar under team control and let him go.

In his tenure with the Marlins after being selected off waivers on December 2, 2019, Aguilar has solidified himself as the team’s primary first baseman, slashing .254/.356/.469 with 14 homers across his two seasons (the stats in this piece are through May 9); that’s good for 126 wRC+ and 1.2 WAR. This season has been particularly good to Aguilar so far. He’s slashing .269/.363/.490 and is in the top 10 in the majors among first basemen in wRC+ (9th) and WAR (9th). Not bad for a waiver pickup! I make mention of his previous clubs’ oversight not to shame them; it’s not the first time a valuable player has been overlooked. But his path to the player he is today is a unique one.

If it feels as though you’re seeing more extra-innings games than usual this year, it’s not just your imagination. Nor is it your confirmation bias — assuming, that is, that you’re not a fan of the new-fangled rule that starts every inning after the ninth with a runner on second and thus regard every instance of such games as a seed between the teeth. Not only are more games going past nine innings this year than last, but the rate of extra-innings games is higher than it’s been in more than half a century. Unfortunately, with scoring at its lowest level since 2015, we’re probably in for more of the same over the remainder of this season.

The extra-innings rule, which was introduced in the minor leagues for the 2018 season and had previously been used in international play, was adopted last year as part of the COVID-19 health and safety protocols. The goal was to end extra-innings games more quickly, thereby reducing players’ time in proximity to each other and their risk of spreading COVID-19, as well as reducing their amount of wear and tear via marathon games. The hope was that the rule would add some excitement as well as a layer of strategy by creating an immediate level of urgency given the automatic placement of a runner in scoring position.

The rule did what it was supposed to do last year in terms of shortening games, at least as measured by innings. Extra-inning games — and here I’m excluding the ones attached to seven-inning doubleheader games — averaged 10.42 innings in 2020, down from 11.26 in ’19 and 11.17 in ’18. The percentage of games going past 11 innings dropped to 0.7%, down from 2.3% in 2019 and 2.8% in ’18. Only two games lasted into the 13th inning, compared to 37 in 2019 and 39 in ’18.

As for “excitement,” that’s subjective, but the rule gained a surprising amount of acceptance within the game once people saw it in action. In November, Major League Baseball Players Association executive director Tony Clark told Sportico’s Barry Bloom that the players were interested in continuing with the rule in order to cut down the stress on pitchers’ arms and position players’ legs, and commissioner Rob Manfred loved it, of course, crowing, “It was obviously adopted as a health and safety rule so games wouldn’t go on too long. But I just think it had appeal even to some traditional members of the media.” Read the rest of this entry »

There have been some scary moments in the first few weeks of the 2021 major league season. On April 28, Phillies Manager Joe Girardi was ejected after both Didi Gregorius and Bryce Harper were hit by pitches while they were playing the Cardinals. Harper’s incident was particularly scary as he was hit in the face with a 97 mph fastball. On April 5, Cubs catcher Willson Contreras was plunked by a 93 mph fastball to the helmet. Two days later Reds rookie Jonathan India had a similar moment after a fastball ricocheted off his helmet.

It’s not your imagination: batters are being hit by wayward pitches at a record clip. Ken Rosenthal of The Athletic made note of the trend this morning. Baseball Prospectus’ Rob Mains recently published an excellent breakdown of this year’s record-setting pace for hit batsmen. I was particularly taken aback by this chart showing that prior to 2018, no season in baseball history had a hit batsman in more than 1 in 103 plate appearances:

Mains continues:

There was one batter hit per 96 plate appearances in 2018, a new record. It fell further, to 94, in 2019. Then all the way to 81 in last year’s short, weird season.

This year? Through Tuesday night’s games, it’s down to 74.5. Batters are being hit thirty-eight percent more frequently than in 1901. There are just over eight hit batters for every five just a decade ago. We’re averaging 0.997 hit batters per game in 2021, a single HBP shy of one per game—a level the sport’s never approached. Batters so far have a .309 on-base percentage. Hit batters account for thirteen points of that figure. Ten years ago, there were only eight points of hit batters in MLB’s .321 OBP.

I wanted to take a look at possible reasons the HBP rate is at record levels so far in 2021, but first we need to be clear about which parts of this trend are continuations from previous seasons and which parts are actually new. In 2019, Devan Fink demonstrated that the HBP rate per plate appearance was approaching the highest levels seen since the early 1900s. He looked at increased velocity and reliever usage to demonstrate that while a pitches’ speed didn’t necessarily mean a pitcher had worse command, relievers had a larger share of HBP than their starting counterparts.

We are reaching peak levels of Shohei Ohtani early in the 2021 season. The true two-way play we were teased with in 2018 is now on full display, with both hitting and pitching in the same game. But as incredible as the hitting has been, there are still questions about Ohtani’s performance as a pitcher: In 18.2 innings, he has somehow pitched to a 2.41 ERA and 3.96 FIP despite a 22% walk rate that is third worst in the league among pitchers with 10 innings or more. Yet in the midst of massive control issues and everything he’s doing at the plate, Ohtani is continuing to develop as a pitcher, adding a multi-faceted cutter to the pitch mix.

There’s a Jekyll and Hyde nature that comes about even within Ohtani’s starts. Take a look at his April 26 outing in Texas to see what I’m talking about.

Updating Ohtani's night on the mound…

1st inning: 4 runs, 2 hits, 2 walks, HBP, 1 K, 11/29 strikes
Since: 0 runs, 1 hit, 0 walks, 8 Ks, 30/46 strikes https://t.co/H9xcc9hH6i

— Jack Harris (@ByJackHarris) April 27, 2021

Something obviously clicked after the first, and all was well again. But looking at his pitch usage that night tells a story itself about where Ohtani is in his development as a pitcher.

It’s an overly simple bit of visualization, and it should be pretty clear what’s going on: Ohtani is largely only comfortable with the fastball and splitter. You can see that the slider, curveball and cutter barely feature, with the latter two popping up in the first inning but not after and the slider appearing only in the fifth and sixth. That’s in line with his career (70 innings) to date: fastball (52% usage), splitter (21%), slider (12%), curve (6%), and cutter (7%). Not that there isn’t precedent for a pitcher who can live primarily off of a four-seam/splitter mix (cf. Kevin Gausman), but it’s a dangerous line for a starter to walk, especially with Ohtani’s command as is.

In 2018, Matt Barnes had a promising season for the Red Sox. He struck out 36.2% of the batters he faced en route to a 3.65 ERA and 2.71 FIP. His one weakness? He walked 11.7% of the batters he faced, a dangerous number. That pattern carried through to 2019; he struck out 38.6% of his opponents but walked 13.3% of them. That strikeout rate is wonderful, but the walks gave him little margin for error, as evidenced by 2020, when he struck out 30.4% of his opponents (still great) but walked 13.7% on his way to a below-replacement-level season.

In 2021, you’ll never believe it — Barnes is striking out the world again, with a 48.4% strikeout rate that’s fourth among relievers, behind only Aroldis Chapman, James Karinchak, and Josh Hader. Oh yeah — he’s also walking 4.8% of his opponents and has been quite possibly the most valuable reliever in the game. Let’s get an explanation for that, shall we?

At surface level, it’s easy! Take a look at swinging strike rate, a statistic that becomes reliable quickly:

A 19.1% swinging strike rate is excellent; top-of-the-league excellent, really. Also true: Barnes hasn’t changed his pitch mix. He’s a two-pitch reliever, with a riding four-seamer and hammer curve. He throws them both roughly half the time, and they spin more or less exactly opposite out of his hand, which seems to help them both play up:

Great, problem solved. Hard curveball, decent fastball, they both play into each other’s deception, sounds like a good reliever to me. One small problem: there are maybe 50 relievers like that in baseball, and Barnes was also like that in the past, when he was far more walk-prone without his current killer strikeout numbers.

After three weeks of these rankings and plenty of feedback — both positive and constructive — I’ve decided to change the way pitching factors into overall team quality. I had been using FIP to assess pitching performance, but using only peripherals undervalued some teams who were actually quite good at preventing runs and overvalued other teams who couldn’t keep runs off the board despite good pitching fundamentals. So instead of using straight park- and league-adjusted FIP as the pitching metric, I’ll be using a straight 50/50 split of FIP and RA9- beginning this week. This gives us a way to evaluate a team’s pitching staff with a blend of actual run prevention (including teams who may or may not benefit from good defense) and pitching talent. This 50/50 composite is shown below as SP- and RP-. The rest of the factors remain the same — offense is represented by wRC+ and combined with the two pitching factors to create an overall team quality metric. Then a team’s expected win-loss record (“luck”) is factored in to produce a power ranking.

There’s a new team on top of the rankings this week. Despite losing Luis Robert for months on Sunday, the White Sox rose to the highest spot in the rankings after allowing just five total runs to score last week. Their starting rotation has been the best in baseball by a wide margin — the runs allowed by Lucas Giolito on Sunday were the first a White Sox starter had allowed in a week. There are certainly some concerns about their outfield, with two of their young stars now out for extended periods of time. Read the rest of this entry »
