I believe through June, his O-Swing was under 30%... he seemed to come a little undone in that regard the 2nd half of the season - but there's no doubt that was a big part of his season, and huge 1st half. Good stuff though, well done.

Thanks! And yeah, I agree. Just from my memory, he seemed to whiff more and be less selective after the ASG. I couldn't find much to back it up, so I stuck with year-over-year comparisons. If and when he leaves Baltimore, I'll put together an article on how to stop him based on what we know from his time here and his relative decline in 2013. Didn't want that information being public yet :P

Patrick....I think you want to change '2012' in the first paragraph to '2013'....although it's true for 2012 also!

Shoot, you're right! Good catch!

The way he hit and his approach the last 3-4 months of the season makes me wonder how much he has turned things around and how much he can carry into 2014.

I agree. I imagine 2013 is his best season ever, but he'll always have spurts of high OBP with singles and doubles that just won't be as prolonged as the first 81 games of this past year.

He should have a 900ish OPS in 2014. Still very valuable but not what he did last year.

His big thing, which he lost for a stretch last year, is maintaining his approach. He started pressing a little in the second half which changed his ability to make contact. I'm really hoping the O's keep pushing for a long term deal with him.

Not likely...but he can still be an AS level player and I would expect that.

Any chance there's a mirror that isn't behind a paywall?

 

Chris Davis came into the major leagues in 2008 as a highly touted slugger from East Texas who was expected to hit monster home runs in bunches. He hit 17 home runs in a little less than half a season, but the next three seasons were the most frustrating three years of his baseball career. That began a stretch during which his swing was under heavy scrutiny and suffered numerous ill-advised changes. Davis was chosen for this article because the swing changes he made or was encouraged to make are some of the “go-to” changes hitting coaches will push upon their players.

co8.gif

Let’s look at bright-eyed Chris Davis as he hits a home run in his first year in the show. Here he has an upright stance coupled with some moving parts. He loads his hands down and tight to his body as his front leg moves. Not the simplest move, and Davis seemed to be in organization that considered simpler better. There is obvious intent to hurt the baseball in his swing, but that intent wouldn't translate into production until three years later, when he was traded away from the Rangers.

 

Take a moment to get familiar with the identity of Chris Davis. He holds his hands very deep, with his back elbow at a 90-degree angle. During the gather phase of his swing he uses a decent-sized leg lift combined with a slight lowering of his hands. His natural approach is incredible for a power hitter. Watch his hips. The front of his hips angles up while he inwardly rotates his back hip just a bit. He then lines his whole swing up with his hip to give an upward trajectory to the ball. He torques his hips back early then aggressively begins to open them, all while holding his shoulders square. This is great hip flexibility. The one drawback is his back knee. It ends up in a great place but is a tad late getting there. Watch how Davis’ back knee rotates back toward the catcher before driving forward and down. If 2008 Chris Davis wanted to get everything into the ball he had to commit extremely early.

 

At this stage, Davis had to commit to the ball prematurely, but the changes he made in an attempt to rectify this issue were superficial.

 

Mid 2009:

cvyo.gif

Here Davis has essentially the same stance, but the movement of his front leg is much smaller. Everything appears smooth and relaxed, but Davis’ numbers didn't reflect a positive change in his swing. This is not the best angle, but look at his back leg. See how it snaps through well after the ball is off the bat. Let’s do some baseball algebra. His back knee was timed to fire after his front leg had been moving for X amount of time. With a smaller leg lift, his front leg is further through his swing progression at time X. His backside is now playing catch-up.

At this point, David was demoted to Triple-A, and the parade of new swing changes accelerated.

 

 

Late 2009:

78d.gif

The stance is now much wider with more bend in his legs. He is also holding the bat lower. His stride is still small and contained, and his hands barely move at all. Even though his extremities are relatively calm, his whole torso bends and drifts toward the plate. There is no momentum in this swing. It’s only through pure strength that he can hit this ball out. His follow-through falls off to the side.

 

The next change was to lower his stride again, which made him land in a different pattern than the one to which he was accustomed. Watch his front foot. Davis naturally moves his front foot and knee in unity, but ere they are disjointed. His knee comes down and then his foot kicks out onto a more pointed landing position.

 

2010:

4l1.gif

Davis is back to his narrow and upright stance of old, but his hands are even lower. The stride is minimal, and he lands on a deliberately pointed foot. This is where Davis really got lost; his stride isn’t doing anything for him here. The point of a stride is to get a hitter’s energy going forward. In this swing Davis slides his foot forward but has generated no momentum; all he's done is widen his stance. It’s likely that he was being told to get his front foot down earlier. Some hitters can make this adjustment with great success, like David Wright, who lands on a pointed toe, then transfers his weight forward, plants the heel, and fires the swing.

 

Look at Davis' posture here. Remember, as a rookie he set his hip angle very early and then rode it out through the progression of his swing. With his foot being down so early he has no chance to set his hips. The hips try to reach their natural alignment at the very end of the swing out of habit, but the hips are at one angle and the shoulders at another. Imagine playing tetherball on a pole with a big kink in the middle. Without a stable axis to fire his swing around, his stroke is on life support.

 

Late 2010:

742p.gif

Davis is back in the majors. Stance is upright and hands are back about shoulder high. He’s gotten rid of that terrible striding pattern. Now when he strides he brings his momentum with him. He has also aligned his posture better, leading to a stronger follow-through. His balance is much better compared to his swing in the previous months.

 

2011:

Rangers:

n3j.gif

Orioles:

8un.gif

 

Davis is returning to his natural stance and stride. He’s back to using a higher leg lift, and his aggressive hand-loading movement shows up. With the Orioles, he reclaims another small but significant mechanical feature. As a Ranger, he had tried to keep his head still, likely thinking that it would help him see the ball. The Orioles let him move his head however he wants. His head now moves forward and down over the duration of his swing. His backside is much smoother with Baltimore. That back knee doesn’t appear to snap at the end of the swing. Rather, it works in unison with the front side.

 

2012:

3n89.gif

Davis is becoming the homer-hitting machine he was always meant to be. His swing looks like it did when he was rookie. Everything is a bit slower and more controlled. Pay attention to the timing between his hands moving down and in and his leg moving forward. It’s an athletic movement not seen since his rookie season. His hips clear through the zone much earlier. He keeps his hands in tight so the early clearing off his hips actually increases his torque. In Texas, Davis tinkered with a handful of unnatural movements. The Orioles slowed down his stride, refined the movement of his back knee, and allowed him to clear his hips earlier.

 

2013:

r4pa.gif

The monster is out of his cage. Davis' swing is now a finely tuned piece of horsehide-demolishing machinery. Five years later, that superfluous movement of his back knee toward the catcher is gone.

 

Let’s look at four things in Davis’ swing and compare how he dealt with them while with the two organizations he's played for.

 

The Upright and Narrow Stance
Rangers: Wider, more bend; lower the hands.

O’s: Upright and narrow; don’t sit back on the back leg quite so much.

 

Head moving forward and down
Rangers: Took it away; keep the head still.

O’s: Keep it smooth.

 

The Stride
Rangers: Shorten it. No, take it away. No, land on your toe.

O’s: Slow it down just a bit

 

The aggressive hand-load
Rangers: Depends on where your hands are starting this week.

O’s: No issue with the hand-load.

 

This is not meant to blast the Rangers. Swinging a baseball bat is a complex movement pattern. While with the Rangers, Davis tried to adopt a new pattern on several occasions. The Orioles worked within his pre-existing pattern to maximize the overall movement.

 

The bigger issue here is how every mechanical change will alter a hitter’s timing within his own swing. It appears that Davis' natural timing pattern was to slot his hands back from their starting position and into his body as his front leg rose up then down. Once his foot does get down he immediately launches the bat through the zone.

 

When Davis changes his starting hand position, he changes how long it will take to slot his hands back. When his stride changes, his timing is altered again. His natural tendency is for his hands to be deepest in his stance just after his front knee starts tracking to the ground. With a smaller stride, his knee tracks down at a different time.

 

Davis is the type of hitter whose swing launches as soon as the front toe touches down. When he touched his toe down to the grounder earlier, he changed his timing. Landing on a pointed toe so early in his swing progression also put him in a much weaker position and destroyed his natural sense of timing. On top of that, restricting his head's forward motion changed how he saw the ball.

 

You might be wondering whether Davis made these changes on his own during his time in Texas. That’s entirely possible, but the changes he made (widen out, lower the hands, quiet the stride, get the foot down earlier, keep the head still, etc.) are some of those most commonly recommended by hitting coaches. These “corrections” are made in the hope of minimizing error while increasing balance and control within a swing.

The Orioles, however, saw a power hitter. Power hitters need their legs to drive the swing, and the O's made sure that Davis' legs established a strong position early to provide a powerful foundation. As a Ranger, Davis tried to minimize risk in his swing. As an Oriole, he's maximized the reward.

I can't believe no ones commented on this article. It explains why he seemed so lost from 2009-2011. It gives me great hope that his breakout was for real.

I love articles where the writer intelligently breaks down the mechanics of hitting.


Davis's power is here to stay for sure. He's a 30+ homers and doubles, high slg % and ISO power guy for the foreseeable future.

There is still legitimate concerns about the batting avg and OBP.

Nice to see the Orioles make a change in a player for the better. Very informative article.
