Vlad Jr. Makes History With Derby Win, but He’s Coming Up Short Elsewhere

Vladimir Guerrero Jr. wasn’t precisely the forgotten man on the 2023 House Run Derby at T-Cellular Park; this scribe was hardly alone in predicting he’d win. However the 24-year-old slugger didn’t put up an astronomical whole of dingers the best way hometown favourite Julio Rodríguez did within the first spherical (breaking Guerrero’s personal 2019 report of 40 homers, at that). Nor did he cruise into the finals by a lopsided rating the best way Randy Arozarena did in knocking off the top-seeded Luis Robert Jr. within the semifinals. Guerrero did begin his night time by steamrolling Mookie Betts, then narrowly eked out wins over each Rodríguez and Arozarena to take house the championship that eluded him in 2019, when he was runner-up to Pete Alonso. In victory, he joined his father, who gained in 2007, as the primary father-son duo to win the Derby. Congrats to Vlad and Dad.

With Blue Jays supervisor John Schneider serving as his pitcher, Guerrero — considered one of simply three contestants who had participated in a earlier Derby, together with Alonso and Rodríguez — wanted till his fifth swing to get on the board, however as soon as he did, with a 453-footer, he discovered his groove. He beat Betts handily, 26–11, then walked off in opposition to Rodríguez, needing only one homer in bonus time to win, 21–20. He hit 25 within the finals, a report for the shorter spherical (two minutes as an alternative of three), then needed to wait out Arozarena, who completed regulation with 20. Crucially, Arozarena solely had the usual 30 seconds of additional time as a result of he hadn’t gotten the gap bonus, unlocked when a participant hit two homers with projected distances of no less than 440 toes — one thing Guerrero managed in all three rounds. Arozarena ran out of each fuel and time as his closing fly balls fell quick; he completed with 23 homers to make Guerrero the champion, the second-youngest in historical past by a day (1993 winner Juan Gonzalez was youthful).

Guerrero will function a reserve for Tuesday night time’s All-Star Sport after beginning at first base in every of the previous two seasons. Yandy Díaz was voted to begin for the AL, and it’s powerful to complain when he’s hitting .323/.408/.515 for a 165 wRC+, the best of any first baseman in both league by 10 factors (NL starter Freddie Freeman is second at 155) and the second-highest of any certified hitter behind solely Shohei Ohtani.

Diaz’s 165 wRC+ is harking back to the league-leading 166 Guerrero put up throughout his 2021 season. We’re now two years faraway from that breakout marketing campaign, when at age 22, Vladito made a run on the Triple Crown, falling quick however nonetheless hitting a formidable .311/.401/.601 with 48 homers and 6.3 WAR. His house run whole led the league, as did his on-base share, a small comfort for ending “solely” third in batting common; likewise, he led in whole bases and slugging share and was second in WAR, a fairly good offset for ending “solely” fifth in RBIs.

Once you’re 22 years outdated and the son of a Corridor of Famer, a season like that sends expectations into the stratosphere, so it’s come as one thing of a disappointment that Guerrero’s follow-up seasons haven’t been as much as that commonplace. He hit .274/.339/.480 with 32 homers, a 132 wRC+, and a couple of.8 WAR final 12 months, and arrived on the All-Star break batting .274/.344/.443 with 13 homers, a 120 wRC+, and (gulp) 0.4 WAR this 12 months. A great — or not-so-good, really — a part of that decline in worth is Guerrero’s protection, which has gone downhill rapidly. I’ll get to that under, however what everyone seems to be questioning is what’s occurred to his offense. In taking a look at his numbers, a couple of issues stand out.

For one, regardless of the early-season indications on the contrary, Guerrero has gotten much less selective. In 2021, he chased simply 28.3% of pitches exterior the zone, however in every of the previous two seasons, he’s as much as 34.2%. As you possibly can see from these warmth maps, final 12 months it was particularly a matter of chasing excessive, and this 12 months, he’s chasing excessive and low as properly:

Guerrero doesn’t strike out a lot for an influence hitter; actually, his 15.6% charge is 0.2 factors decrease than in 2021 and 0.8 factors decrease than final 12 months. The issue is that his outcomes when chasing pitches exterior haven’t been pretty much as good as they as soon as had been. Right here’s a have a look at his outcomes when chasing excessive pitches, these in Gameday zones 11 and 12:

The decline hasn’t been uniform, however his AVG and SLG are decrease than in 2021, although his exit velo and xSLG are literally larger. He’s swinging and lacking much more typically when he chases excessive, with each his whiff and swinging-strike charges in these areas a lot larger than in 2021. Together with the pitches he’s chasing in zones 13 and 14, exterior and under the strike zone, his .130 batting common and .190 slugging share are down from 2021’s .171/.240 and final 12 months’s .148/.230.

Whereas Guerrero is swinging and lacking extra at pitches exterior the zone, he’s offset that considerably by making extra contact within the zone; this 12 months’s 86.4% charge is down 1.4 factors from final 12 months however up 2.4 factors relative to 2021. He’s hitting the ball extremely exhausting but additionally on the bottom extra typically than in 2021:

Guerrero is scalding the ball, rating sixth within the majors in common exit velocity and seventh in hard-hit charge and touchdown within the 88th percentile in barrel charge. He’s much more spectacular by way of Finest Velocity (the common exit velo of his high 50% of batted ball occasions, a extra helpful measure than the easier-to-find common EV as a result of it filters out the noise), rating third within the majors, and but he’s even under each 2021 and ’22 in that metric.

For as exhausting as Guerrero is hitting the ball, he’s simply not getting the outcomes that ought to accompany it:

Guerrero’s xBA is identical because it was two years in the past, solely this time he’s 33 factors quick as an alternative of 4 factors over. His SLG is 37 factors under final 12 months, however his xSLG is 88 factors larger, and that sample carries over to his wOBA (9 factors under final 12 months) and xwOBA (49 factors larger). His SLG-xSLG differential is the majors’ second-largest, and his wOBA-xwOBA differential is the fourth-largest. Right here’s the rating by the previous class:

I highlighted the three different gamers with wOBA-xwOBA differentials as low or decrease than Guerrero’s; you possibly can see their rankings by sorting the desk. Past them, the remainder didn’t make the lower; see right here as an alternative.

Digging a bit of deeper, it’s Guerrero’s outcomes on fly balls which are notably out of whack:

Although his fly balls are being hit as exhausting, they’re at a steeper angle than earlier than, however even the shorter carry isn’t sufficient to elucidate his shortfalls of 527 factors of slugging share and 272 factors of wOBA. Because it seems, these are the biggest shortfalls on fly balls of any participant in the whole Statcast period, from 2015 onward! He’s obtained a 77-point “lead” in slugging differential:

As an apart, how scary is it that for as nice as Acuña’s season is, he’s right here as properly? So are Swanson and Grisham from this season, and if I’d expanded the desk, Guerrero’s teammate Matt Chapman could be proven at sixteenth, with a -319-point hole (.851 SLG, 1.170 xSLG). Guerrero moreover has a 34-point “lead” over Cruz in wOBA differential, with Swanson third and Acuña fourth, and everyone else via eighth current within the desk above.

Through the Statcast broadcast of the Derby on ESPN2 (that includes Jessica Mendoza and FanGraphs alum Mike Petriello), somebody famous that Guerrero didn’t hit his first homer on the Rogers Centre this 12 months till June 23 and has hit simply three of his 13 homers there, all coming inside a seven-day span. Digging into the info, his slugging differentials for house and away are related in scale, however the underlying numbers are method aside:

What’s going on with that change charge? Guerrero is falling over 500 factors quick within the slugging division on each splits, however the place he’s slugging solely .406 on his Canadian fly balls, he’s at .906 on his American ones. Even on condition that he’s not hitting his fly balls as exhausting at house as on the highway, producing a 15-foot distinction in distance, that also doesn’t account for the way lopsided his cut up is.

The problem could also be his Guerrero’s pull-rate splits. This 12 months he’s pulling 36.1% of his batted balls at house and 43.3% on the highway, in comparison with 43.6% at house and 35.6% on the highway final 12 months and 39.7% at house and 40.2% on the highway in 2021. Observe that these are Sports activities Information Answer classifications; Statcast’s pull percentages differ, typically with larger middle charges, which makes the single-season pull samples sufficiently small that I don’t suppose they imply a lot once we begin taking a look at precise and anticipated numbers. For illustrative functions, I’ll notice that by way of Baseball Savant, Guerrero has slugged .667 on six pulled flies at house, in comparison with a 1.439 xSLG; on 15 such balls final 12 months and 18 the 12 months earlier than, he slugged over 2.000, so it’s truthful to say that he does appear to be shedding out not pulling the ball as constantly at house.

Whereas the Rogers Centre did endure renovations this previous offseason, to my information all of these pertained to the fan expertise, not the sphere of play. The fence distances and heights stayed the identical. Replace: Opposite to the assertion I simply crossed out, the Blue Jays did alter the fence distances and heights, although they made the announcement at a special time than that of the ballpark’s inside. Rating that E-6 on my half [looks at webbing of glove, shakes head sheepishly]. Right here’s what the modifications appear like:

Listed here are the brand new Rogers Centre dimensions LCF now 368 (was 375) with a wall that is larger. RCF now 359 (was 375) with a wall that is a lot larger. pic.twitter.com/dgM7DbkZE2

To either side, the Blue Jays have shortened distances whereas elevating fence heights, although it’s not symmetrical. The distances modifications are much less excessive on the left facet, Guerrero’s pull facet, and likewise with the peak modifications, however these could also be canceled out by his much less pull-happiness this 12 months. In brief, I’m unsure this is sufficient to clarify what’s happening with Guerrero’s fly balls at house, notably on condition that the nearer fences had been extra more likely to improve offense. However when coupled with the stadium’s capability being lowered by about 7%, right down to 41,500, it’s doable the renovations had an affect on air circulation as properly. It does appear value noting that the common distance of hard-hit fly balls (95 mph or larger) has decreased from 363 toes to 357, that whereas the MLB-wide common has elevated by one foot, from 365 to 366. In the meantime, the Blue Jays’ total SLG-xSLG differential of -.015 (.415 SLG, .430 xSLG) is tied for the sixth-lowest within the majors, however the venue’s -.028 hole on fly balls (.836 SLG, .861 xSLG) is in the course of the pack, rating because the Thirteenth-lowest of the 30 ballparks.

For no matter purpose, Guerrero isn’t hitting the ball as exhausting at house, and he’s getting the shaft at an historic degree on his fly balls each house and away, which can or might not have one thing to do with the modifications. Aside from the pull splits, I can’t establish any particular points as to why that might be, however Nonetheless, I do suppose it’s truthful to determine that some optimistic regression might be in retailer.

As famous, one different factor that stands out about Guerrero is his defensive decline. Recall that in 2021, he moved from third base to turn out to be a full-timer at first base, the place he was a really nice shock. Now, he’s instantly turn out to be DH-caliber:

Yikes. To the best of the divider, I’ve damaged out Guererro’s Outs Above Common splits, and as you possibly can see, he’s been particularly poor; he’s the majors’ worst first baseman at coming in and at shifting to his proper, towards third base. Whether or not he’s missing in focus, carrying his offensive shortcomings (resembling they’re) into the sphere, or missing in mobility relative to 2 years in the past, he has to wash that up. Over the course of a full season, the distinction between good Vlad and dangerous Vlad within the discipline quantities to greater than a win, and for a workforce that’s within the thick of the AL Wild Card race — at 50–41, the Jays are tied for the second spot however only a recreation forward of the Yankees (49–42) and two video games forward of the Pink Sox (48–43) — each win counts. Nonetheless, I’d count on that we’ll see a extra productive Guerrero on the plate within the second half, and whereas some will credit score his Derby win at having jump-started his season, you and I’ll know higher.
