News broke last night that Rays’ prospect Brendan McKay will make his debut on Saturday; Marc Topkin of the Tampa Bay Times had the initial report. The reasons for Tampa calling up McKay, who was ranked 14th overall this spring by Eric Longenhagen and Kiley McDaniel before moving up to 11th on THE BOARD in the post-draft update this month, are threefold. First, the Rays need a pitcher Saturday. As Topkin noted in his piece, Ryan Yarbrough pitched three innings in last night’s 18-inning win over the Twins, and he won’t be able to take the bulk of the innings tomorrow as originally planned. Second, the Rays are in what should be an incredibly close race for the playoffs and need every competitive advantage they can get. And third, tying into the second, McKay is a very talented pitcher who gives the Rays the best shot at winning.

Before getting to McKay’s talents, let’s first examine the competitive landscape in the American League. Much has been made of the parity in the National League, with nearly every teams having some shot at the playoffs halfway through the season. The top-heavy nature of the American League has made for a bunch of haves and have-nots, with only a handful of teams having a realistic shot at the playoffs. Looking at the playoff odds, the Rays are one of those teams:

Brandon Belt isn’t having a particularly good year. For once, I don’t just mean that his counting numbers are unimpressive; he’s long been a player whose production has outstripped his reputation, as light-slugging first basemen tend to be, and playing in San Francisco’s extreme scoring environment hasn’t helped. From 2012 to 2018, he produced 3.4 WAR per 600 plate appearances, All-Star-level production, despite never really hitting for power or average.

This year, his defense has dragged him down near replacement level (note to the Giants: Belt really shouldn’t play the outfield), but his hitting isn’t up to his usual standards either (a 107 wRC+ that equals last year for his worst full-season rate). Even as Belt’s production wanes, though, he’s actually getting more fun to watch. Why? Well, you never know when he’s going to drop down a bunt, regardless of situation, and bunting for a hit is among the most fun plays in baseball.

When you picture the ideal player to shift against, Brandon Belt is almost a perfect match. He’s left-handed, pulls a ton of his groundballs, and isn’t fast enough that a second baseman in shallow right field might not have time to throw him out on a grounder. When shifting exploded in frequency from 2014 to 2016, Belt was the kind of player who gave teams a reason to do it. In 2015, 54% of the balls he put in play were against a shift, up from 14% in 2013. By 2016, that number climbed to 78%, and it’s bounced around 80% ever since.

At first, Belt had no clear counter. By the end of 2016, he’d bunted only five times in his major league career, going 2-4 with a sacrifice. Teams shifted on him with impunity, and Belt lashed grounders into the shift. His groundball rate decreased, but that’s not a way to punish shifting; it’s merely a way to ignore it. He tried bunting more in 2017, but it was only middlingly effective — he finished 3-6 on the year, and two of those singles were bang-bang plays; he easily could have been 1-6. “Bunt against the shift” is a great idea in theory, but Brandon Belt wasn’t doing it well enough in practice.

Bunting skill isn’t fixed, though, and Belt proved it. His bunts in 2018 were crisper, better-executed, and better-aimed. Take a look at this surgical strike against the Padres:

Freddy Galvis’s kick-stop drives the point home: there’s no reason to bother fielding that ball. For the season, Belt went 4-6 on bunts, and none of the singles even drew a throw. That .667 on-base percentage will do, even if he did embarrass himself in a Bay Area tilt:

Hey, they can’t all be perfect. That’s no different than a grounder into the shift, even if it probably feels worse.

Remember all the way back in the previous paragraph where I said they can’t all be perfect? Well, I lied. Brandon Belt is perfect on bunts this year, and he’s getting increasingly audacious. He’ll bunt in situations where a runner is valuable, sure. Leading off an inning against a decent reliever in a close game? That’s a great time to get a runner on first, and the shift is just asking for it. He doesn’t even hesitate:

That’s too obvious, though. Brandon Belt isn’t about bunting only in situations where a runner on first is most important. He’s in it for the love of the bunt. 1-1 count with two outs and a one-run lead? Sure, Belt will bunt on you:

Are runners on first valuable with two outs? Not at all! Still, Belt’s feeling it. Put away your run expectancy tables and feel the magic. Sometimes you just have to bunt.

How about against an Orioles righty in Camden Yards, a situation where Belt is probably as likely to hit a home run in a single plate appearance as he’ll ever be? Oh yeah, absolutely:

Keep your home runs; Belt will take his not-even-guaranteed base and be happy with it. The Giants hit three long balls in this game. Brandon Crawford, he of the .141 career ISO and 8.7% home run per fly ball rate, hit two home runs. Lefties batting against Oriole righties are in the best possible situation to succeed. Gabriel Ynoa has a 6.45 FIP and 6.75 ERA this year, for crying out loud! Belt doesn’t care, though. He’s bunting.

If you think those last two bunts are questionable, his latest one takes the cake. With the bases empty, a bunt single and a walk are exactly the same. Honestly, a bunt single and a walk are the same almost all the time, but especially with the bases empty. 3-0 count, pitch that might well be called a ball? Bunts away!

Bunts on 3-0 are rare, because they’re ridiculous. 3-0 counts often end in walks, without the hassle of having to connect on a bunt and reach base safely. When Matt Carpenter did it last year, I looked into it and found that he was only the third player to get a fair bunt down with a 3-0 count and the bases empty in the last 10 years. Well, that statistic is now outdated, because Brandon Belt is the fourth.

Think about what bunting on 3-0 entails. A 3-0 count is the best place a hitter could ever find himself. After 3-0 counts this year, major league hitters as a whole walk 60.6% of the time. They get on base 72.8% of the time. On the rare occasion where they don’t walk, they often hit home runs — 5% of non-walk at-bats that hit 3-0 end in a dinger. Literally every offensive stat is improved; batters have posted a .233 ISO (against .180 ISO overall), a .322 BABIP (.296 overall), and a .309 batting average. Brandon Belt doesn’t care. He just wants to bunt.

At this point, I think we can say that Brandon Belt is drunk with bunt power. In a twist, though, that isn’t really new. When Cody Bellinger bunted on 3-0 in 2017, Jeff Sullivan investigated and found a 3-0 bunt attempt from Belt that went foul in May 2017. Brandon Belt wasn’t even a good bunter in 2017! That bunt rolled foul, and it might be good that it did; the Dodgers weren’t particularly over-shifted. He just felt like bunting.

Hittable righties, favorable counts, spots where a runner on first isn’t all that valuable? That’s all irrelevant. Brandon Belt sees an opening, and he attacks. It’s not going to stop teams from shifting against him — he’s grounded into a shift 41 times this year, which means the shift is saving more in grounders than it gives back in bunt singles. Still, if you’re playing against Belt, maybe keep your third baseman close to home until the count gets to two strikes. Honestly, maybe leave him there with two strikes, too. Belt hasn’t attempted a bunt with two strikes yet in his career, but at the rate he’s turning bizarre situations into bunt singles, it’s only a matter of time.

The MLB All-Star Game is just two weeks away, and the Baltimore Orioles have been campaigning hard for Trey Mancini to appear on the American League roster. This is understandable — at 22-58, the Orioles have given fans little to cheer for this year, and Mancini is rather unambiguously the best player on the club. Teammate Chris Davis has been vocal in his support for Mancini, and the organization went so far as to put together a full-fledged (if tongue-in-cheek) campaign video for him.

Baltimore’s enthusiasm surrounding Mancini’s All-Star candidacy helps draw attention to what has been a fantastic bounce-back season for the 27-year-old. He owns a .303/.362/.557 line and a 139 wRC+, good for 24th-best in the majors. His 7.9% walk rate and 19.5% strikeout rate are both career bests, and his xSLG, xBA, and xwOBA figures each put him in the 87th percentile of all major leaguers or better.

That set of numbers contrasts sharply with where we found Mancini in 2018. He smacked 24 homers for a second year in a row, but that was the lone bright spot in an otherwise underwhelming offensive season. He hit just .242/.299/.416, posting a 93 wRC+ and 0.29 BB/K figure. Because Mancini was a nightmare in the field — his -17.2 defensive runs above average were the fifth-worst in baseball — he finished the season as a sub-replacement level player. In most other organizations, he likely would have lost his starting job, but on the talent-bereft Orioles, he’s gotten a second chance. How has he made the most of it? Read the rest of this entry »

2018 was the end of an era for the Washington Nationals. After failing to get Bryce Harper to agree to a long-term contract with the organization, his final year in D.C. appeared destined to have something of a valedictory nature, a long farewell to the player who was drafted to be the face of the franchise. The script seemed to be in place for one last hurrah. After all, this was a team that during the Pax Brycetania won the NL East four times in six seasons, with their 555 wins second only to the Dodgers. 2018 would be the year they finally got over the playoff hump and won the World Series, after which the credits would roll, and captions would indicate what had happened to each of our favorite characters.

Oops.

Projected to go 89-73 by ZiPS, the Nats underperformed by seven games, finishing 82-80. Thanks to the Braves misbehaving and butting into contention before their number was called, Washington fell out of the postseason race for good by the All-Star break. There was a silver lining in the emergence of Juan Soto, who somehow needed just a month more seasoning to turn from a South-Atlantic League star into a major league one, effectively becoming better at being Bryce Harper than Bryce Harper. The way forward in 2019 was clear: a full season of Soto and Victor Robles, together with Patrick Corbin, would make up for the loss of Harper, and constitute enough of a gain that it wouldn’t be a major problem that Brian Dozier was a poor replacement for vintage Daniel Murphy. ZiPS even projected the Nats to be better in 2019 than it did in 2018.

Oops.

An 8-18 run from mid-April to mid-May left Washington rubbing elbows with the Marlins in the wastelands at the bottom of the NL East. The team’s gone 20-9 since, but that’s only been enough to get them to the precipice of a .500 season, rather the edge of greatness. At 39-40, they still stand eight games behind the Braves, a team with a lot more prospect currency to trade for short-term improvement at the deadline. Read the rest of this entry »

Six weeks ago, the Miami Marlins looked dead in the water. They were 10-31 at the time, and given their tough schedule ahead, they had a small yet tangible shot at eclipsing the 1962 Mets’ record for the most losses since integration. Jay Jaffe covered Miami’s putrid start, and the details were very grim indeed:

They’ve lost seven games in a row… They scored a grand total of eight runs in that span, never more than two in a game… Did I mention that it’s been a full week since the last Marlins position player drove in a run, or 11 days since one of their players homered? Or that it’s the team’s only homer this month, hit by a 29-year-old rookie named Jon Berti?

Miami’s ineptitude at the plate explained most of the trouble; the Fish were scoring barely 2.5 runs per game. They were also on pace to hit fewer than 100 home runs, an astonishingly feeble output in today’s dinger-happy game.

But in baseball, yesterday’s trends are tomorrow’s distant memory. Miami commenced a six-game winning streak the day Jaffe’s post went live, and they’ve gone 20-17 since publication — an 88-win pace. Obviously, they’re not that good: even terrible squads can string together a .500 stretch over 40 games. Still, the club’s recent surge has given them a better record than four other teams in the majors. Even stranger, the Marlins are… gulp… surprisingly entertaining! Read the rest of this entry »

The lingering suspense over whether the Yankees could break the major league record for consecutive games with a home run, which they had tied at 27 on Monday night, lasted until Tuesday night’s sixth pitch from Blue Jays starter Clayton Richard to Yankees leadoff hitter DJ LeMahieu. Boom!

In the brief interval that it took this scribe to tweet about that record — admittedly, while juggling a beer and a scorebook in section 422 of Yankee Stadium — Aaron Judge homered as well. In fact, solo home runs accounted for the Yankees’ entire output in their 4-3 victory, with Gleyber Torres and Edwin Encarnacion joining the party, too. The latter even broke out the parrot against his old team for just the second time since departing in the winter of 2016-17, that while a hawk literally watched his dinger from atop the right field foul pole.

Here’s the Yankees’ new perch after Wednesday, when Didi Gregorius’ second-inning home run off Toronto’s Trent Thornton further extended the streak (LeMahieu added another one in the Yankees’ come-from-behind win as well):

It doesn’t take the eyesight of a hawk to note that 11 of those 13 seasons are from the post-1992 expansion era, which has featured at least one home run per team per game — a level previously topped only in 1987 — in all but five seasons (1993, and every year from 2010-14 except for ’12). Four of those seasons, including three of the top seven, are from the 2016-19 period, which, as I noted on Monday in relation to Justin Verlander’s performance, is the first four-year stretch with at least 1.1 home runs per team per game. This year’s 1.36 per game is the all-time high, 0.1 ahead of the previous high set just two seasons ago, an increase of 8.7%. It’s 0.21 home runs per game (18.8%) higher than last year, and 0.5 homers per game (58.4% higher) than in 2014, the year of the post-1992 low:

If we factor in the ever-increasing strikeout rates, the rise is even sharper. This year’s rate of home runs per batted ball — that is, HR/(AB-SO+SF) — is 5.31%, 0.49 points (10.1%) higher than the previous high in 2017, 0.86 points (19.3%) higher than last year, and 2.08 points (64.2%) higher than 2014.

I’ll get back to that momentarily, but it’s worth noting that when the Yankees’ streak began in late May, only three of the seven players who contributed the most home runs to last year’s record-setting total of 267 were active, namely Aaron Hicks (who tied for second on the team with 27 homers), the sixth-ranked Torres (24), and seventh-ranked Gary Sanchez (18). Since then, the 1-2 punch of Giancarlo Stanton (38) and Judge (27) has returned from lengthy stints on the injured list, and Gregorius (27) has returned from off-season Tommy John surgery. Miguel Andujar (27) is out for the remainder of the season due to surgery to repair a torn labrum, but on June 16, the team traded for Encarnacion, who currently leads the league in homers (24, including three as a Yankee).

All of which is to say that it’s been a mix of A- and B-list players who have not only propelled this particular Yankee streak but have helped the team out-homer all but three other teams, namely the Twins (149), Mariners (145), and Brewers (138):

Such are the Yankees’ power reserves that the acquisition of Encarnacion led to Frazier, who has hit a robust .283/.330/.513 (117 wRC+), being optioned to Triple-A Scranton/Wilkes-Barre, and remaining on the farm even as Stanton went back to the IL with a sprained posterior cruciate ligament in his right knee, the result of a baserunning mishap early in Tuesday night’s game. He’ll miss the upcoming London series against the Red Sox, and will be out for longer than the 10-day minimum. With or without Stanton, who has played just nine games this season, it’s not hard to imagine a more complete Yankees lineup overtaking the Twins in the home run department. But even if they don’t, the rather patchwork lineup has kept them on pace to eclipse last year’s total, which is a hint that the homer situation is simply getting silly.

League-wide, no individual is on pace to challenge Barry Bonds‘ single-season home run record of 73; Christian Yelich, who leads the majors with 29 homers, would finish with 62 if he were to keep hitting them at the same pace over the Brewers’ final 82 games as he has over his first 73 (he’s missed seven games with assorted aches and pains). However, with only five teams past the halfway point in their schedules heading into Thursday (the Mariners have played 84 games, the other four of those teams 82), a total of 56 players had reached the 15 homer plateau, meaning that they were on pace for 30 homers. The league-wide record for such players is 47, set in 2000. Four of the top five totals hail from the 1996-2001 stretch, with the fifth coming in 2017, when 41 players reached it. Similarly, 18 players have reached 20 homers, and are on pace for at least 40. The record for players with 40-homer seasons is 17, set in 1996, and we haven’t seen more than nine players do it in any Statcast-era season; there were nine in 2015, but just three last year. Yelich, Pete Alonso (27 homers through the Mets’ 81 games) and Cody Bellinger (26 homers through the Dodgers’ 82 games, including one on Wednesday) are on pace for at least 50 homers. Only in 1998 and 2001 did more than two players reach that plateau, with four apiece in both of those years, including the single-season record breakers, Mark McGwire and Barry Bonds.

Meanwhile, 14 of the majors’ 30 teams are on pace to set franchise records, with the top four surpassing last year’s Yankees:

All but three of the 30 teams are averaging at least one homer per game. Twenty-two teams are on pace for 200 homers, one fewer than in all of baseball prior to the 1994 players’ strike. Only in 2017, when 17 teams reached that plateau, have there even been as many as a dozen teams to do so. Eight teams are on pace for 250 homers, a level reached by just six teams ever prior to this year. The mind reels at these numbers.

While one can point to the general trend of batters making greater efforts to elevate the ball — whether to hit it over shifted infielders or not — it’s more accurate to call that an adaptation to the new reality. The scientific evidence again points to the ball itself as being the driving factor. Earlier this week at The Athletic, Dr. Meredith Wills published a follow-up to last year’s breakthrough article, which itself was a follow-up to MLB’s Home Run Committee report. That committee, led by Dr. Alan Nathan, professor emeritus of physics at the University of Illinois, had found that the recent home run spike was caused by a decrease in the ball’s aerodynamic drag, but found no physical difference in the balls that would explain the change.

Conducting her own measurements using digital calipers and disassembled baseballs, Wills concluded that post-2015 balls’ laces, which were an average of nine percent thicker than balls from the 2010-14 period, were producing less bulging at the seams, yielding a more spherically symmetric ball with less aerodynamic drag — thus allowing them to fly further.

For her latest study, Wills examined 39 balls from this season, which she found differed from the 2015-18 balls and even earlier ones. Most notably, she found “demonstrably lower” seams, only 54.6 percent ± 15.0 percent as high as those on balls from previous seasons. By measuring the coefficient of static friction, she also found that the leather on this year’s balls is relatively smoother, concluding, “the static friction for the 2019 balls is 27.6 percent lower, a statistically significant result demonstrating the leather covers are genuinely smoother.” She measured the bulging of the seams and found, “Not only were the 2019 balls virtually round, what bulging they did show was slightly negative, suggesting the seams might be slightly ‘nestled’ into the leather.” The significantly rounder balls, which have thinner laces than last year’s (more in line with 2000-14 samples) produce even less drag than before, and thus even more carry. Wills noted that both the seam and smoothness issues jibe with anecdotal reports from pitchers about difficulties in gripping this year’s balls, as voiced by players such as Sean Doolittle, Jon Lester, and Noah Syndergaard.

As for commissioner Rob Manfred’s recent suggestion that a better-centered pill (the core of the ball) is a factor in creating less drag, Wills was largely dismissive, writing, “[T]his is the most difficult result to produce without significant manufacturing changes, since existing techniques make it hard to keep the pill from being centered to begin with… Therefore, it seems unlikely that pill-centering would explain a sudden change in drag; at the very least, we would be remiss not to also examine other possible sources.”

All of Wills’ articles on the topic, which are behind a paywall, are worth reading, but it should suffice to say that there’s ample scientific evidence that the ball is carrying this. And how. Check out these numbers, which combine Statcast’s average distance measurements with those from our stat pages:

Fly balls are carrying an average of four feet further than last year, and eight feet further than in 2015. Add to that a general increase in fly ball rates and you have a recipe for significantly more homers. Perhaps too many homers. Combine that trend with the aforementioned strikeout trend and lower batting averages — though this year’s .251 is three points higher than last year, it’s in a virtual tie with 2014 for the second-lowest mark of the DH era, which began in 1973 — and the result is a greater percentage of runs being scored via homer than ever before. Here’s an historic look at what Joe Sheehan christened “the Guillen Number” a decade ago at Baseball Prospectus:

For a period of over two decades, from 1994-2014 — two decades that saw record home run rates, PED scandals, expansion, new ballparks galore — the rate of runs scored via homers was remarkably stable around 35%, never deviating more than two points in either direction. It hit 37.3% in 2015, and has climbed at a rate of about two points per year since, to heights previously unseen, and now, both statistically and aesthetically, the situation sticks out like a sore thumb. Ken Rosenthal called it “Bludgeon Ball” earlier this month, and I think the description fits. This is brute force baseball, and while it doesn’t lack for a certain amount of excitement, it’s very lacking in subtlety. When nearly half the league is on pace to set home run records, and the vast majority of teams are set to exceed totals that were once very rare, we’ve gone too far.

It’s time for MLB and Rawlings (which the league bought last year) to fix this. Wills noted that while Manfred has maintained that Rawlings hasn’t changed its manufacturing process or materials “in any meaningful way,” this may be an issue of semantics:

The Home Run Committee found that Rawlings regularly implements production improvements, including changes to the yarn (February 2014), the pill (March 2014, May 2015), the leather (June 2014, February 2017, August 2017) and the drying process (March 2016, February 2018). The Committee described these changes as “largely technical in nature and very unlikely to be in any way related to the (2017) home run increase.” That being the case, things like enhancing leather smoothness or drying baseballs more efficiently might not be considered “meaningful” to manufacturing.

While this may have been a reasonable attitude in the past, such enhancements now appear to have compounded, producing a more aerodynamic ball.

Wills recommended another committee report with the goal of using the information to tighten specifications, improve quality control and “determine further production improvements.” To these eyes — and I know I’m not alone — such improvement would include the restoration of some normalcy. When a player’s 40-homer season, or a team’s mountain of 200 homers, is no longer worthy of celebration, is as common as a garden weed, we’ve lost something. It’s worth searching for how to get that special something back.
