Chris Taylor Puts the Super in Superutilityman

On Tuesday, July 20, Chris Taylor led off the bottom of the first inning with a double off the Giants’ Alex Wood. But he was still hungry, so he homered twice and drew a walk later in the same game.

On Wednesday, Chris Taylor led off the bottom of the first inning with a homer off the Giants’ Logan Webb. But he was still hungry, so he later singled off Webb.

On Thursday, Chris Taylor led off the bottom of the first inning with a single off the Giants Anthony DeSclafani. But he was still hungry.

On Friday, Chris Taylor led off the bottom of the first inning with a double off the Rockies’ Chi Chi González. But he was still hungry, so he later singled off Daniel Bard.

On Saturday, Chris Taylor led off the bottom of the first inning with a single off the Rockies’ Kyle Freeland. But he was still hungry. Read the rest of this entry »


The Weekend in No-Hit Bids and the Effect of the Sticky-Stuff Crackdown

For a brief period on Saturday night, it appeared possible that not only would the single-season record for no-hitters fall, but that two pitchers — the Angels’ Patrick Sandoval and the Astros’ Framber Valdéz — would spin no-hitters on the same day for just the third time in history. Neither was successful, but on Sunday, the Yankees’ Domingo Germán put in his own no-hit bid, one that not only fell short but turned into a debacle. While this season’s breakneck pace of no-hitters has slowed down drastically, with just one in June and none in July after six in April and May, the drop in the number of close calls hasn’t been quite as sharp, but even so, the concentration of such games from Saturday and Sunday was notable.

Valdéz had the earlier of the two no-hit bids on Saturday night. The 27-year-old lefty has generally pitched well this season, but in his first four outings of June had struggled with his mechanics and compromised his command, walking 15 in 22.1 innings, and getting tagged for 27 hits and 15 runs (13 earned). Even against a Rangers team that entered having lost 10 straight games, his command woes — which had abated somewhat in his July 18 outing against the White Sox, when he walked just two hitters in 6.1 innings — returned, but this time he was effectively wild, walking six in six innings without allowing a hit or a run; he threw just 53 strikes out of 99 pitches. Despite sandwiching two first-inning walks around a wild pitch, and walking two more in the second, he escaped both jams and kept the Rangers off the board. Only twice did he retire the side in order, but each of the other two walks he issued came with two outs.

Valdéz needed a game-high 23 pitches to get through the sixth, with the final two hitters of the frame — Nate Lowe, who walked, and Curtis Terry, who struck out looking — each battling through eight pitches. For manager Dusty Baker, it was a no-brainer to remove him even given that he hadn’t given up a hit. Via MLB.com’s Brian McTaggert, “If we’d left him out there to get the no-hitter, he’d be up to 140 pitches,” said Baker, who decades ago gained a reputation for pushing his young pitchers too far, one that’s no longer applicable. “You’ve got to think logically what’s best for him.” Read the rest of this entry »

The 2021 Replacement-Level Killers: Center Field and Designated Hitter

For the full introduction to the Replacement-Level Killers series, follow the link above. While still focusing upon teams that meet the loose definition of contenders (a .500 record or Playoff Odds of at least 10%), and that have gotten about 0.6 WAR or less thus far — which prorates to 1.0 WAR over a full season — this year I have incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included them here because the team’s performance at that spot is worth a closer look.

As noted previously, some of these situations are more dire than others, particularly when taken in the context of the rest of their roster. As with some of the previous entries in this series, a few of these situations include midseason turnarounds where returns to normalcy are camouflaged by early-season struggles; one problem spot, that of the Rays’ designated hitters, was shored up in impressive fashion with Thursday night’s acquisition of Nelson Cruz from the Twins. As with previous entries in this series, won-loss records and Playoff Odds are through yesterday (July 22, in this case), but statistics through the day before (July 21).

Yankees (50-44, 3rd in AL East, 43.9% Playoff Odds)

For the Yankees, this season was supposed to mark a changing of the guard in left field, with Clint Frazier having hit and fielded well enough in late 2020 to take over regular duties from the aging Brett Gardner. Like so much else in the Yankees’ lineup, however, things haven’t worked out. Frazier hit just .186/.317/.317 (83 wRC+) with -0.8 WAR and lost his starting job before being sidelined in early July by what was originally diagnosed as vertigo but is now considered to be a vision problem, possibly related to his previous concussion-related issues.

The 2021 Replacement-Level Killers: Introduction & First Base

In a race for a playoff spot, every edge matters. Yet all too often, for reasons that extend beyond a player’s statistics, managers and general managers fail to make the moves that could improve their teams, allowing subpar production to fester at the risk of smothering a club’s postseason hopes. In Baseball Prospectus’ 2007 book It Ain’t Over ‘Til It’s Over, I compiled a historical All-Star squad of ignominy, identifying players at each position whose performances had dragged their teams down in tight races: the Replacement Level Killers. I’ve revisited the concept numerous times at multiple outlets and have presented it at FanGraphs in an expanded format since 2018.

When it comes to defining replacement level play, we needn’t be slaves to exactitude. Any team that’s gotten less than 0.6 WAR from a position to this point — prorating to 1.0 over a full season — might be considered fair game. Sometimes, acceptable or even above-average defense (which may depend upon which metric one uses) coupled with total ineptitude on offense is enough to flag a team. Sometimes a team may be well ahead of replacement level but has lost a key contributor due to injury; sometimes the reverse is true, but the team hasn’t yet climbed above that first-cut threshold. As with Supreme Court Justice Potter Stewart’s definition of hardcore pornography, I know replacement level when I see it.

For this series, I’ll go around the diamond, pointing out the most egregious examples of potential Killers at each position among contenders, which I’ll define as teams who are above .500 or have playoff odds of at least 10.0%. That definition covers 17 teams (sorry Braves, Cubs, Cardinals, and Nationals, but you’ll have to do this without my help). If one of the aforementioned fringe teams gets their record or odds above the threshold this week, I’ll do an additional Very Special installment at the end. And while I may mention potential trade targets, I’m less focused on these teams’ solutions than I am the problems, because hey, human nature.

This first installment will cover first basemen. All statistics within this piece are through Saturday, July 17. Read the rest of this entry »

Vladimir Guerrero Jr. Is Soaring to New Heights

On the strength of his monster home run and an additional RBI groundout, Vladimir Guerrero Jr. took home MVP honors from the All-Star Game at Coors Field on Tuesday night. In doing so, the 22-year-old slugger — who also nearly decapitated National League starter Max Scherzer with his hardest-hit ball of the evening — became the youngest player ever to win that award. The performance was just the latest chapter of Guerrero’s breakout, as he lives up to the high expectations set by his pedigree and his precocious development.

If for some reason you haven’t seen his highlights from Tuesday night, here’s Guerrero’s first-inning plate appearance, where his 111.1 mph rocket back through the box produced such a close call that Guerrero felt obliged to apologize to Scherzer, who remarked after the game, “I’m alive… that’s the success story… I’m just grateful I still have a blue eye and a brown eye”:

And here’s Guerrero’s third-inning homer off Corbin Burnes:

The 468-footer was the longest All-Star Game homer of the Statcast era, surpassing Kris Bryant’s 2016 shot by a good 58 feet. With it, Guerrero became the second-youngest player to go yard in an All-Star Game, after Johnny Bench did so in 1969 at the age of 21 years and 228 days. In winning MVP honors, Guerrero, at 22 years and 119 days, surpassed Ken Griffey Jr., who was 117 days older when he won in 1992. Meanwhile, Guerrero and dad Vlad joined the Griffeys and Bobby and Barry Bonds as the only father/son combinations to homer in the All-Star Game.

With the single-game spotlight and honors behind him, Guerrero is now angling to become the youngest position player to win a regular season MVP award; he won’t surpass pitcher Vida Blue, who was 22 years and 64 days old on the final day of the 1971 season, but would surpass Bench, who was 22 years and 298 days on the final day of the ’70 season. He and his father, the AL MVP in 2004, would be the first pair to win the award. Of course, the competition for Guerrero to win is daunting given the ongoing tour de force of Shohei Ohtani. A month ago, Guerrero led the AL in all three Triple Crown categories and WAR, kindling a debate over the merits of that combination relative to Ohtani’s pitching. At that point, Dan Szymborski estimated Vladito’s chances of winning the Triple Crown at 19.1%, but the five-homer lead he held over Ohtani has become a five-homer lead for Ohtani (33-28) thanks to the Angels’ superstar’s recent flurry. Guerrero’s .332 batting average and 73 RBI both still leads the AL, as does his .439 on-base percentage, 189 wRC+, and 4.6 position player WAR, though Ohtani has taken over the combined WAR lead at 5.5, and has a slugging percentage 40 points higher than Guerrero’s .658.

Regardless of whether he’s first or second in any category, Guerrero has taken a massive leap forward from his performances in 2019 and ’20, which were solid enough for a 20- or 21-year-old, but hardly All-Star caliber. After batting .272/.339/.433 (105 wRC+) in 2019, he showed more power last year, hitting .262/.329/.462 (112 wRC+); his ISO jumped by 37 points, and his home run rate rose from 2.9% to 3.7%, a gain of about 28%.

Guerrero is showing even greater in-game power this year — his display in the 2019 Home Run Derby provided more evidence of raw power than anyone this side of Iggy and the Stooges — as you can see from the basic numbers, but before discussing that, it’s worth acknowledging his improved plate discipline. He’s cut his rate of swinging at pitches outside the strike zone from 31.6% as a rookie to 27.4% last year and then 25.3% this year; among qualifiers, he’s climbed from the 46th percentile to the 70th and now the 83rd. As a result, he’s posted the majors’ fifth-largest gain in walk rate from 2020 to ’21, jumping 5.7 percentage points to 13.9%; only Starling Marte (+7.9%,), Joey Gallo (+7.7%), Carlos Correa (5.9%), and Andrew McCutchen (+5.8%) have gained more. While Guerrero is striking out more as well (up two points to 17.6%), he’s still in the 70th percentile in that category.

The biggest difference in his performance relative to 2020, though, is how much harder he’s hitting the ball:

Vladimir Guerrero Jr. Batted Ball Profile
Season GB/FB GB% EV Barrel% HardHit% AVG xBA SLG xSLG wOBA xwOBA
2019 1.50 49.6% 89.5 6.9% 37.9% .272 .254 .433 .433 .329 .326
2020 1.96 54.6% 92.5 8.7% 50.8% .262 .260 .462 .437 .338 .331
2021 1.35 44.8% 95.2 16.7% 55.6% .332 .318 .658 .625 .453 .436

Guerrero’s exit velocity already ranked in the 93rd percentile last year, but he was hitting grounders about twice as often as fly balls. He still hits more grounders than flies, but his 9.8 percentage point drop in groundball rate is the majors’ fourth-largest behind Jonathan Villar (-14.0%), Kyle Schwarber (-10.6%), and Kevin Pillar (-9.9%). He’s nearly doubled his average launch angle (from 4.6 degrees to 8.4), and with it, has nearly doubled his barrel rate while increasing his already-high hard-hit rate. A picture is worth a thousand words:

Guerrero has improved in every Statcast-tracked category here — even the ones that pertain to his speed and defense, the evidence of the better conditioning and work he’s put into learning a new(ish) position — except for maximum exit velocity, where he already ranked in the 99th percentile. In case you were worried that he was stagnating, he has actually shown improvement there nonetheless, from last year’s 116.1 mph to 117.4 (for what it’s worth, he topped both with a 118.9 mph single in 2019). Fittingly, where last year’s hardest-hit ball was a lineout to second base, this year’s was a home run off the Rays’ Ryan Yarbrough, the first of the two he hit on May 24 at the team’s temporary Dunedin home:

That first one had a projected distance of 461 feet, four short of his regular season career long, set just eight days earlier off the Phillies’ Brandon Kintzler, also in Dunedin:

Guerrero’s All-Star Game homer topped that, albeit with an assist from Coors Field’s altitude (which added 32 feet, according to Weather Applied Metrics’ Ken Arneson) if not the wind (which took away 10).

On the subject of harnessing his incredible bat speed towards improving his ability to get the ball in the air, in April our own Carmen Ciardiello wrote about the possibility of Guerrero improving what he called his attack angle to better launch the ball. Using an approximation based upon the top 5% of each player’s hardest-hit batted balls, Ciardiello compared Guerrero to the other mighty sluggers with similar maximum exit velocities and estimated his attack angle at 8.71 degrees. Only Giancarlo Stanton (8.74 degrees) had one nearly as flat, while Ronald Acuña Jr. had the highest angle at 17.86 degrees, followed by Trout at 16.94. In my attempt to track this as a potential explanation for Guerrerro’s year-to-year improvement, I calculated that based upon his top 5% of hard-hit balls, his attack angle has actually dipped to an average of 6.69 degrees; five of his 13 hardest-hit balls thus far have negative launch angles, meaning that they were hit on the ground, while only four are double-digit positives, all of them homers. I’ll leave it to Ciardello for further interpretation of those results.

Looking at Guerrero’s year-to-year improvement by pitch type what quickly becomes apparent is that he’s now a serial murderer of four-seam fastballs; he’s gone from a .254 AVG, .465 SLG, and .356 wOBA against them last year to a .386 AVG, .830 SLG, and .538 wOBA. Among players with at least 100 PA ending in four-seamers, only Juan Soto has a higher average, while those other two figures are tops. Guerrero’s 18 runs above average against four-seamers is the highest of any player against any pitch, and represents a full 18-run gain relative to last year as well. His other big improvements are against sliders, where he’s gained eight runs (from +1 to +9) primarily by improving from .576 SLG to .633, and sinkers, where he’s gained six runs (from +3 to +9) primarily by improving from .485 SLG to .614.

Using 200-PA cutoffs for both last year and this one, Guerrero owns the majors’ biggest gains in both slugging percentage and wRC+. Here’s the top 15 for the former:

And here’s the latter:

Player Team 2020 2021 Dif
Vladimir Guerrero Jr. TOR 112 189 78
Bryan Reynolds PIT 72 146 74

Kyle Schwarber CHC/WAS 91 140 49
Nolan Arenado COL/STL 76 120 44
Minimum 200 plate appearances in both seasons.

I should point out that my somewhat arbitrary choice of 200 PA as a cutoff for both seasons — made in part because I wanted batting title qualifiers for 2020, but then 186 PA just looked weird — meant leaving Ohtani off the tables given that he had just 175 PA last year. His 332-point gain in slugging percentage (from .366 to .698) and 98-point gain in wRC+ (from 82 to 180) dwarf the gains of Guerrero and the rest, so if you want to imagine a version of the tables with him on top, you’re free to do so.

So long as we’re talking improvements, it’s worth noting Guerrero’s progress on the defensive side. After a rough introduction to the majors at third base in 2019 (-9.4 UZR, -3 DRS, and -19 OAA in just 824 innings), he split last season between first base (-1.8 UZR, -4 DRS, -2 OAA in 324 innings) and DH. Particularly given his weight and conditioning issues — he showed up to summer camp somewhere in the vicinity of 285 pounds — his future appeared to tilt towards the latter slot, limiting his ceiling. After apologizing to his teammates for showing up out of shape last summer, he lost 42 pounds this past winter and appears to have kept the weight off. His mobility and flexibility have improved and so have his defensive numbers, which are now within hailing distance of average (-0.5 UZR, -2 DRS, and 0 OAA in 576.2 innings).

Even for a player who was so heavily touted as a prospect — recall that he was the consensus number one heading into 2019 — Guerrero has come a long way in a short time, and what he’s doing at such a young age puts him alongside the likes of Soto and Fernando Tatis Jr., not to mention some of the game’s other recent prodigies:

Right now, Guerrero has the highest slugging percentage and wRC+ of any of the bunch, though preserving that distinction is no small challenge given the amount of season remaining. Our rest-of-season projections forecast him to add another 2.3 WAR, which would tie him with Seager for fifth on the list. At the rate he’s going, it would hardly be a surprise if he climbs higher.
