I’ll all the time have an affinity for hitters with a knack for vertical bat variability. To successfully cowl pitches at totally different heights within the strike zone, a hitter has to fluctuate the angle of their bat relative to the bottom to create elevate. To hit a pitch on the high of the zone for a line drive, the bat ought to be flatter, and to elevate a pitch on the backside of the zone for a line drive, the bat ought to be steeper. It’s a easy idea that some hitters can execute with extra consistency than others. Jackson Merrill is a type of guys.
Once I first actually began moving into the mechanics of hitting, Mike Trout was the dude who made it straightforward to know vertical bat variability. Classic Trout’s decrease half regarded nearly an identical throughout all swings, however relying on the peak of the pitch, his whole torso angle would alter. By means of the years, gamers like Michael Brantley, Freddie Freeman, and Trea Turner have all executed spectacular ranges of vertical bat variability, too. And unsurprisingly, all of them maintained (or nonetheless do) strikeout charges properly under the league common with nice gap-to-gap line drive expertise. When Eric Longenhagen first in contrast Merrill’s swing to that of Brantley, I turned very impatient anticipating what the Padres outfielder would do within the huge leagues. To date, he’s exceeded expectations.
By means of his first 121 profession video games, Merrill has hit for a 125 wRC+ with a .290/.321/.484 slash line. Over the previous month, he’s discovered his energy stroke to associate with his excellent line drive swing, and through that span, he’s been among the best hitters in baseball, with a 182 wRC+ throughout 104 plate appearances. It’s come at a great time for the Padres, who’ve picked it up and are solely three video games behind the NL West-leading Dodgers.
Merrill’s sound mechanics and manufacturing on the plate are all of the extra spectacular contemplating that he’s nonetheless only a 21-year-old rookie who can also be studying a brand new place. Though his outfield expertise within the minors was restricted to 45 innings in left area final yr at Double-A, he’s already changed into one of many high defensive heart fielders within the sport (6 OAA).
His skill to go down and get it with the very best of them whereas nonetheless protecting the highest of the strike zone is the important thing to his success so early in his profession. Under is a desk highlighting his performances in each the higher and decrease thirds of the zone:
Merrill Efficiency by Vertical Zone
| Zone | xwOBA | League Rank* |
|---|---|---|
| Higher Third | .381 | 27 |
| Center Third | .432 | 29 |
| Decrease Third | .386 | 25 |

*Out of 194 batters to see no less than 1,250 pitches as of Aug. 20
Elite hitters have all totally different shapes of manufacturing. Juan Soto mashes all the things on the high of the zone, Aaron Decide crushes all the things within the coronary heart, and Yordan Alvarez demolishes all the things down low. However it’s unusual for hitters to be this productive on each excessive and low pitches. In actual fact, among the many 194 hitters who’ve seen 1,250 pitches this season, solely two different gamers have xwOBAs that rank within the high 30 on pitches in each the higher and decrease thirds of the zone, Ketel Marte and Marcell Ozuna, who’re two of the very best 11 hitters within the sport by wRC+. Merrill and Ozuna are the one two hitters with top-30 xwOBAs in all three vertical thirds.
As I mentioned earlier than, a hitter must make use of a flatter swing path on the high of the zone and a steeper one on the backside. Sounds straightforward sufficient, however the tough half is producing sufficient bat velocity throughout a spread of bat angles to make it work from a injury perspective whereas sustaining the physique management to make contact. What’s notable right here is how Merrill does this: In contrast to most hitters, Merrill retains his bat vertically oriented towards high and low pitches, which permits him create sufficient elevate to shoot the gaps regardless of the peak of the pitch. It’s a stability of energy and finesse that Merrill appears to have mastered.
I may throw a bunch of numbers at you to elucidate this specific ability, however one of the simplest ways to know that is by watching what he does together with his physique and bat. Let’s have a look:
Higher Third
Earlier than watching the decrease third swings, listed below are a number of fast notes. He maintains his posture and shoulder airplane throughout all three of those swings. Due to that, he retains his bat on the identical vertical airplane as these pitches so he can sq. up the underside a part of the baseball to create backspin however not get up to now beneath it that he pops them up. Additionally, his torso backbend on the second swing is unbelievable. This transfer is most noticeable from a hitter like Shohei Ohtani, who proper earlier than contact bends his higher physique backward to offer his barrel house to get behind the ball. Few hitters have the required higher physique or t-spine flexibility to do that; Merrill is one in all them. Okay, now onto some swings within the decrease third:
Decrease Third
Take note of his again shoulder on every of those swings. Merrill’s physique and bat are transferring collectively as he swings, and he makes use of his again shoulder as a information to get his barrel on airplane with pitches within the decrease third. Whether or not it’s a back-foot breaking ball or a dotted heater away, his again shoulder angle traces up his swing.
The vital factor to remove from all of that is Merrill has an awesome understanding of methods to use his higher physique to get his bat on airplane with pitches at totally different heights. That’s the elite ability carrying his sport proper now. He has the expertise to develop further instruments and sharpen those he presently owns as he beneficial properties extra expertise. He’s already began tapping into his energy extra during the last month or so. He nonetheless chases too many pitches and struggles towards lefties, albeit in a small pattern of plate appearances (70 wRC+, 127 PA), however once more, he’s 21 and figuring issues out in his first huge league season. What we’re seeing from him proper now could be primarily his start line as a hitter, and that’s actually thrilling.
